[PHP] Form Actions

[Shaun]

Hi,

I have a number of forms on my site, and each form can be accessed from a
number of different pages. Can anyone suggest a way I can monitor this so
that when the submit button is pressed the user is returned to the page they
were on before. This is also complicated by the fact that I have a system
that returns the user to the same page if there are errors on the form...

Thanks for your help

The code is just a function it's not a "page" in itself. I use it
in a form that display checkboxes for each Sunday in a month.
Someone else may use it by providing the arguments via a form in
the manner you suggest. The function, however, is just that, a
function.

I do this by passing a hidden value in the post. The value can
identify anything you like, on mine it identifies the domain the
form was submitted from (though thinking about this now I can do
this without a hidden value, but you get the idea!).

The problem with this is that it means you have to have a separate
copy of each form unless you can construct the hidden input value
using other variables.

Cheers, Greg.

RE: [PHP] $_SESSION stuffs that come with php.ini

[esctoday.com | Wouter van Vliet]

Hmm .. I haven't been on the list for a while so it took me some time to
answer ;).. Anyways, what I believe is a possible cause for your problem is
that there simply ain't no session started. Maybe the "always start session
before the php page request" setting was On if not configured, but is now
Off in your ini file.

783 ; Initialize session on request startup.
784 session.auto_start = 0

Might wants to be changed to

783 ; Initialize session on request startup.
784 session.auto_start = 1 

Also check this one

773 ; Whether to use cookies.
774 session.use_cookies = 1

In combination with

850 ; trans sid support is disabled by default.
851 ; Use of trans sid may risk your users security.
852 ; Use this option with caution.
853 ; - User may send URL contains active session ID
854 ;   to other person via. email/irc/etc.
855 ; - URL that contains active session ID may be stored
856 ;   in publically accessible computer.
857 ; - User may access your site with the same session ID
858 ;   always using URL stored in browser's history or bookmarks.
859 session.use_trans_sid = 0

If both are set to "0", sessions simply won't work since PHP cannot know
about the session id. If session.use_cookies is enabled, and
session.use_trans_sid is not than you should have Cookies enabled in your
browser for sessions to work. 

Or if you're on Windows, pay special attention to

771 session.save_path = /tmp

Which should then be changed to smth like c:\temp

That's pretty much what I can say about it .. If neither of those work, just
read the entire [Session] section in the php.ini file.

[PHP] Output data repeatedly more than once

Hi all, 
   I am creating a simple receipt system whereby user will enter relevant
info   
via a text form and using echo method to output and print the receipt data. I've
used CSS as the front-end . My question is, is it possible to output the receipt
information more than once on a single page (Browser) as I would need to
print out the receipt thrice for the different department as required.

A hassle is right.  What about your visitors who use a text-only browser
(or surf with images turned off) or who depend on text-to-speech readers?

This sort of thing is, IMNSHO, unnecessary and the wrong approach; it
makes the web harder to use without making it a safer place.  The form
should be designed correctly and safely in the first place.  We don't use
this sort of approach to prevent buffer overflow attacks and it shouldn't
be used anywhere else, either.

Hi,

I need to send the following link

view_day.php?mysql_date=2003-09-23&user_id=35&set_form_actions=true&new_user
=yes&user_name=Kate%20Dickie&link_text=diary&link_action=availability.php?ne
w_user=yes&user_name=Kate%20Dickie.

This may seem strange that I have 2 ?'s in the link but the point here is
that I need everything after the 2nd ? to be used as a link on the following
page - which is actually held in a session.

However when I try to do this, the link_action held is
'availability.php?new_user=yes', how can I get everything after the 2nd ? to
be held in the session var?

Thanks for your help

Re: [PHP] download queue

[Marek Kilimajer]

I would do it this way. Output your files and update bandwith usage:

while($out=fread($file, 4096)) {
	echo $out;
	UPDATE bandwith_usage SET bandwith_usage = bandwith_usage+1 WHERE 
second = UNIX_TIMESTAMP() LIMIT 1
	if(mysql_affected_rows()==0) { // if this is the first output in this 
second
		INSERT bandwith_usage SET bandwith_usage = 1, second = UNIX_TIMESTAMP()
	}
}

When you are about to start a download, check the bandwith usage first, 
in this case for the last minute:

SELECT AVG(bandwith_usage) usage FROM bandwith_usage WHERE second > 
UNIX_TIMESTAMP() - 60

usage * 4096 gives you usage in bytes per second. If it exceeds your 
limit, output a html page (sorry...), else open the file and start the 
above loop.

You might want to change 4096 to a higher value. You should also 
implement a garbage collector that will remove old bandwith usage data, 
the collector can make usage statistics too.

Alex wrote:

the logic of it escapes me. If anyone has ever done this before, seen 
the code behind this before, or knows basically how this would be done, 
I'd be more than happy if you would share your wisdom with me.

Oscar F wrote:

Hello all,

I'm having a problem with PHP/WebDAV. Here's my problem:

I am working on a system that keeps track of documents. The documents 
are stores based on document ids, and the filename is saved on the 
database along with the document id and file type/size, and the file is 
renamed to just the id number.

Now I need to use webdav to let user edit files as it is normally done 
with webbad, with the problem that the files have no name/extension so I 
have to recreate them with php. I created a couple of php files, that 
capture the GET, PROPFINDS, PUTs, etc. The idea is that the user opens 
the php file specifying the file id, and the php file looks up the name, 
retrieves the content of the file and sends it to the client (this is 
currently being done without problem, when the php script sees a GET, it 
looks for the file and send it). I need the php script to be able to 
capture PUT as well and when it gets one, it takes the data and saves it 
to the file that has the id. The problem is, I open the .php file and I 
get the data of the file, but when I save, my php code is replaced with 
the actual text of the file as if the file they're editing is the php file.

Any help or advise you could provide me about this would be really

[PHP] fsockopen()

[Phil Ewington - 43 Plc]

Hi All,

I am having problems with fsockopen() and wondered if anyone else has
encountered this behaviour. My problem is that when connecting to an invalid
domain I cannot trap the errors.

I have tried setting a variable then testing the value, which prints a
warning to the screen...

$sck_handle = fsockopen($hostname, $port, $errno, $errstr, $timeout);
if (!$sck_handle)
{
// socket could not be opened.
$http_statuscode = "Error:" . $errno . "-" . $errstr;
}
else
{
...
}

How can I get $errno & $errstr, are these for read/write errors rather than
socket initialisation? I need to know why the socket could not be opened so
I can give an appropriate error message.

TIA

6 250 MB/s / 4 kB (4096 B) = 1562.5 queries per second
Well that's too much. At this load 4096 can be increased to 409600, the 
database load would be only 15.625 queries per second.

  I would do it this way. Output your files and update bandwith usage:

  while($out=fread($file, 4096)) {
  echo $out;
  UPDATE bandwith_usage SET bandwith_usage = bandwith_usage+1 WHERE 
  second = UNIX_TIMESTAMP() LIMIT 1
  if(mysql_affected_rows()==0) { // if this is the first output in this 
  second
  INSERT bandwith_usage SET bandwith_usage = 1, second = UNIX_TIMESTAMP()
  }
  }

  When you are about to start a download, check the bandwith usage first, 
  in this case for the last minute:

  SELECT AVG(bandwith_usage) usage FROM bandwith_usage WHERE second > 
  UNIX_TIMESTAMP() - 60

  usage * 4096 gives you usage in bytes per second. If it exceeds your 
  limit, output a html page (sorry...), else open the file and start the 
  above loop.

  You might want to change 4096 to a higher value. You should also 
  implement a garbage collector that will remove old bandwith usage data, 
  the collector can make usage statistics too.

[PHP] file_exists on different server...

[Tristan . Pretty]

I'm referencing an image on a different server, and it keeps changing 
URL's
Very odd, but t get round that, I tried...

if (file_exists("http://www.othersite.com/image_1.gif";)) {
$image_show="http://www.othersite.com/image_1.gif";;
} else {
$image_show="http://www.mysite.com/image_1.gif";;
}

but it always seems to do the else command, even though I know the file 
DOES exist...

Just for the record, this problem exists from our parent website to one of 
the subsideries, we're not referencing anything we shouldn't... ;-)

Any work arounds?

[PHP] PHP 4.3.3 and IIS

[Michael Kochendoerfer]

Hi,

does anyone know how to handle file and directory paths on a IIS 5.0 
server? Problem is that the server has multi-domain and each domain has an 
associated 'root' dir below e:\webspaces.

So if one uses relative path strings, an opendir() for example will fail. 
One has to use "e:\\webspaces\\root_of_domain_1\\images\\" to access the 
/images folder of the configured domain 1.

I'm sure there are functions and env vars to accomplish this, but I'm quite 
new to PHP and didn't find them yet.

Please... can someone enlight a newbie? *g*

Thanks in advance!

- Michael

It is a good idea too to use the pear-imagick module which is a wraper for 
imageMagick. With this you can more easily deal with errors

here is an example with the crop function:
http://grincheux.codelutin.org/~monnier/doc/imagick/crop.php

And the other exemples given in the package:
http://grincheux.codelutin.org/~monnier/doc/imagick/

===
If you use it in cli mode, think you can write errors like this:
fwrite(STDERR, "handle failed!\nReason: $reason\nDescription: 
$description\n");
in stead of this:
print "handle failed!\nReason: $reason\nDescription: 
$description\n";

===
I am interseted in writing a simple application using php-gtk and 
php-imagick. If other peoples are interested in this project, just mail me 
to talk about this.

hi marek,

thanx for your suggestion.
i have tried out the tokenizer but
1.  i think its not realy final and can change in the future
2. the tokenizer can only find real php code but i need to find my
simplified php code without an ; on the end of an statement for example.

so the tokenizer doesn't do my job. i'm not far from the right solution it's
a litle step to bring the regex working with embeded parenthesis beetween "
"

i only had 2pregs in the complete source that can catch any type of
registered function call with the simplified syntax ... this is fast enough
for me ...

[PHP] arrays and php

[Angelo Zanetti]

hi I have a table with rows and each row contains a checkbox ( array) and a
record. TD of the checkbox:
echo("");

as you can see the array of checkboxes is called chkR.

When the user clicks a submit button it calls the same
page and the value of the array is received using: $chkR=$_POST['chkR'];
however this variable is doing something weird because if I immediately do:
echo("chk: is array: " . is_array ($chk)); it doesnt display anything, so I
presume it isnt an array, supporting this is also the fact that I try to use
the $chkR in:

$indReqF = array_diff ($indReq, $chkR)

and everytime i run this statement php tells me that the 2nd argument isnt
an array. What is the reason for $chkR not being an array? I have used the
same code on a different page but instead of it posting to the same page
(like in this example) it posts to another page and works fine !?!?!?!?

can anyone help. this is very strange.

Try giving a TemplateTamer a shot. It is not too big, but it can help you

 Is there any way to avoid having this happen using php if someone sits
on a page too long and clicks the back button to go back to a form they
have filled out and not having the values in a session?

To avoid that I always do a header redirect after processing a post from a form,
that way the browser forgets about the page in the middle and avoids that error
showing up. The down side is you have to save any errors in a session variable
and show them on the next page, but it is worth it I think.

If both images have the same size you don't even need javascript:

#mydiv {
background-image : url(http://domain.org/image1.jpg);
background-repeat : no-repeat;
width : 200px;
height : 120px;
}
#mydiv:hover {
background-image : url(http://domain.org/image2.jpg);
background-repeat : no-repeat;

[PHP] pdf question

[Floyd Baker]

Hello...

I have created a routine which outputs a pdf file of 'data only'.
It is to be printed onto a pdf form which I obtain elsewhere.

At present we are printing the blank form.  Then placing it into the
paper tray in order to print the data file to it.  

I would like to cause the data and form to both be printed on a single
sheet, in one operation.  That is; is it possible to cause the two
files to be accessed in sequence, so that there is not a paper feed
between them?  For one to overlay the other?  

Many thanks

Floyd

Thanks Tom...

Now, if I understand this properly,

This should return French_France...

   setlocale (LC_ALL, 'fr_FR');
   echo setlocale (LC_ALL, '');

and this English_ Great Britain

   setlocale (LC_ALL, 'en_GB');
   echo setlocale (LC_ALL, '');

   setlocale (LC_ALL, 'de_DE');
   echo setlocale (LC_ALL, '');

and this Russian_Russia

   setlocale (LC_ALL, 'ru_RU');
   echo setlocale (LC_ALL, '');

Well, all of them return the same thing for me...

   English_United States.1252

The 2 lines I have given in my examples are the only 2 lines in the script.

I must be doing something wrong.

Any ideas?

Thanks

That's a valid complaint, but I fail to see how a correctly-designed form can

RE: [PHP] Cleaning up my messy code

[Didier McGillis]

I can understand that.  When I was a young coder, just fresh out of high 
school going to school for Sport Management, btw I believe and have stress 
to the education board that I sit on for high school and trade school tech 
programs that they not teach specifics about a certain language but that 
they teach the kids the proper way to code, database design, all the 
fundamentals and allow the kids to get a good base (think that is more 
imporatant then anything) and then let them discover their own tools, and 
style and language of choice (notice mine isnt english).

Anyway I'm sorry about the rant.  I imagne that you are writting the 
database and coming up with that piece as well.  While you are writting the 
database you are starting to form the foundation of your site, and coming up 
with revisions.  I find its best to make notes in the db design doc, and 
even in the sql about why you did things the way you did.  You can go back 
and reference these notes and build on them.  Secondly I sit down on my 
laptop and while thinking or coding I make other notes either in my code or 
in a coding document about how the structure of how things are laid out, and 
why I did xml over sql calls and such.  This may sound like a lot of extra 
work, but not only is the foundation to your site documentation, which 
should be written but it will help you get a frame of reference should you 
have to step away from teh project or just need a reminder, also if you 
bring someone else in to help you wont have to spend much time babysitting 
them.

Certainly. This is not a theoretical exercise but frustration with
dealing with my own code, trying to implement revisions, and basically
feeling like I need a map of some kind to know where I am.
That's why I'm interested in what other people really do rather than
theoretical models they think might be the "purest." And it isn't just
code and content separation, which isn't always practical as an
absolute, but code separation. If I have a simple set of actions to
perform, say a series of functions to enter data into a db, review the
entry, edit the entry, etc. how can I organize my code so it is easy to
maintain and so some things can be reused? Objects? Functions? Fuses?
Switches? All of these have their adherents... I'm trying to find one
that adheres to me-- i.e. that is usable without being so extensive and
abstract that I spend more time trying to learn how to fit the framework
than actually getting something done...

Those locales actually have to be available or they will be ignored and that
will depend on what type of system your running on.
For example on my system (linux) I had to do

localedef -ci es_ES -f ISO_8859-1:1987 es_ES

and then a restart on apache to get the Spanish locale working.

(Did I mention manuals :)

Firstly you should be putting double quotes around every value in your
HTML tags.

Revised: (watch wrap)

echo "";

I also changed

". $chkSessionF[$i] ."

into

{$chkSessionF[$i]}

.

You can do it either way. I prefer the latter.

If you're not sure what a value is use print_r() to determine it.

echo "";
print_r($chk);
echo "";

Quick side note on the above code:

You cannot write it like:

echo "".print_r($chk)."";

It will not work.

> can anyone help. this is very strange.

I think your problem may just be the quotes around the values in the
HTML. Give it a shot.

OK, I'm on Windows 2k, and after reading Microsofts docs, I thought it was

Maybe not.

Restart the server?

No way to set this on the fly?


> (Did I mention manuals :)

No, but I got 2 private messages stating "RTFM" and no other comments. They
were a big help. :/

I'm beginning to think this is tougher than I thought.

:/

What I'm trying to do is have my new Class be aware of the LOCALE setting
and take advantage of that info to return translated strings based upon that
setting.

I was hoping not to have a method in my Class to define LOCALE, I wanted to
pick it up from the system, and even let the user set it on the fly.

Thanks for your help Tom.

[PHP] if statement

[Steve Buehler]

I have an "if" statement that I would like to make a little bit more 
generic.  This is how the statement looks now.

if($k2b=="/etc/bind/options.conf.wp" || $k2b=="/etc/bind/rndc.conf.wp" || 
$k2b=="/etc/bind/keys.conf.wp"){
	do this1
}else{
	do this2
}

What I would like to do is to have an array earlier in the script of just 
the items that it is checking for so that it can be more easily changed if 
I put this out as free or shareware software.  Here is what it might look 
like, but I know that if this is possible, it probably won't look at all 
like this:

$array=("/etc/bind/options.conf.wp","/etc/bind/rndc.conf.wp","/etc/bind/keys.conf.wp");
if($k2b==$array){
do this1
}else{
do this2
}
I think that might make enough since to see if someone can help me on 
this.  This would be real nice for me in use in a lot of scripts.

[PHP] storing japanese in mysql (or pgsql)

[Chris W. Parker]

(I posted this to another list yesterday without response, so if it
looks familiar, that's why.)

Hi.

I'm working on a small study aid for myself (and anyone else that wants
to use it) and I could really use the ability to store Japanese
characters in a MySQL or pgsql db. Right now I've created a very large
array.

What I'd like to do is have a form that will allow me to add new
characters whenever needed. So far my attempts at this have failed. It
always seems that the extended characters get turned into their html
entity equivalents before they are inserted into the db.

I'm using euc-jp as the character set.


I'm pretty much lost with this. Anyone have experience with this that
they'd like to share? (on or off list is fine.)


Thanks,
Chris.

The challenge is to create a form that cannot be automated, for whatever reason

Close, but not close enough :)

if (in_array($k2b, $array) ) {
  // do this1
}

http://php.net/in_array

Although depending on the situation I usually set up array's of
this type like this:

$arr = array(
  '/etc/bind/options.conf.wp' => true,
  '/etc/bind/rndc.conf.wp' => true 
  );

Then my condition is:

if (@$arr[$k2b]) {
  // do this1
}

Under windows you could go to control panel ->regional settings ->input locales
and try adding a few and see if that helps.
I only know about apache and that did need a restart to get it to recognize the
new locales available as I think it caches that information.

[PHP] Setting cookies

[Chris Boget]

We have 2 servers, one for development and one for production.  The
development server is "dev.change.wild.net" while the production server
is "change.wild.net".  We are using the following code to set the cookie

$expire_time = time()+60*60*24*30;  // 30 days
setcookie( 'this', $this, $expire_time, '/', $_SERVER['HTTP_HOST'] );
setcookie( 'that', $that, $expire_time, '/', $_SERVER['HTTP_HOST'] );

We are accessing the cookie values using $_COOKIE.  What appears to
be happening is that when we echo the values of the above cookies on
"dev.change.wild.net", it is displaying the values set for on "change.wild.net".
Why is that?  Because "change.wild.net" is the primary domain with 'dev'
being a subdomain?  Is there any way we can force it so that the cookie
values are pulled for the correct domain?

thnx,
Chris

I think you are probably right and I think it is due to tail matching. A 
link from the manual pointed to:

http://wp.netscape.com/newsref/std/cookie_spec.html

What about clearing your cookies when you switch between your dev server 
and your live server. Takes a little more manual effort, but should work.

Re: [PHP] storing japanese in mysql (or pgsql)

characters in a MySQL or pgsql db. Right now I've created a very large

What I'd like to do is have a form that will allow me to add new

always seems that the extended characters get turned into their html

I'm using euc-jp as the character set.

I'm pretty much lost with this. Anyone have experience with this that
they'd like to share? (on or off list is fine.)

Because dev.change.wild.net is within the change.wild.net domain. This is by
design. They are not different domains. You can always use:

1. dev.change.wild.net
2. www.change.wild.net

or

1. change-dev.wild.net
2. change.wild.net

Hope that helps.

You can do this though:

Or if using a recent version of php:

  echo nl2br(print_r($var, 1)); //or something like that

What's the difference between using , or . for concatenation? (I thought

Hello srs,

Q 1.

  Will the methode __clone() have the posibility of
take arguments  It would be usefull to
reinitialize the clone:

  age = $age;
  $this->owner  = $owner;
}

function __clone($owner) {

}


}

$molly = new Ovelha(2, "Eduardo");

$dolly = $molly->__clone("Igor");

print $dolly->owner;
print $dolly->age;
?>

Warning: Clone method does not require arguments

that´s sure one can create a wrapper function that
initializes it, but


Q 2.

In some old docs, I´ve read the following:

  For convenience, the engine will suply a function
that imports all of the properties from the source
object, so they can start a by-value replica of the
object, and only override properties that need to be
changed. [The function hasn´t been implemented yet].

 How is it actualy?

So
About Question 1,
How do you re-set properties in the clone at the time
it is cloned... as it is done in the constructor

And has someone any answer to Question 2??

Using a comma is just like using another echo command. So for the above,
you're effectively saying:

echo ""; echo print_r($chk); echo "";

Note that print_r() will (by default) return a 1 (TRUE) upon success, so you
end up with a "1" being printed at the end of your data.

You could also use this method:

echo "".print_r($chk,TRUE)."";

The TRUE causes the output of print_r() to be returned instead of printed
automatically. The benefit to this method is that you don't end up with the
"1" being printed.

It depends on how you define "works" :)

You'll end up with output like this:

Array
(
[0] => one
[1] => two
[2] => three
)
1

which "works" but is not what was desired.

".print_r($pageTitle)."";
?>

Gives me:

If I use the , it's a little closer but still not correct (at least not

Close but I don't know where the one is coming from. Maybe it's saying

The comma isn't concatenation; echo can take multiple arguments.

I've heard statements about passing multiple arguments to echo being faster
than using concatenation, but every benchmark I've tried myself shows them to
be nearly identical. Feel free to try it yourself and post your results. :-)
I'd be curious to see if others reach the same conclusion.

[PHP] HTTP HEAD request using curl??

[Marc Richards]

Is it possible to do a http HEAD (instead of GET, POST or PUT) request using
the php curl extension?  I know that curl itself can do it, but I wasn't
able to find the appropriate CURLOPT constant in the documentation for the
php extension.

I need to do a whole bunch of url calls but all I need is the headers, I
don't have curl support compiled in and I probably won't bother compiling in
if it can't do HEAD (I'll just use fopen).

Has anybody been able to do this?

I tried this, and I think the comma was just slightly faster than the
period. But then again I didn't always get consistent results because I
was trying this out on a machine that is not very fast so the speed at
which is processes something varies quite a bit.

My conclusion was that it's not fast enough to bother changing all my
code, or start writing in a new way.


Although during some testing I did find that writing loops in the
following way is faster than normal.

$counter = -1;
while(++$counter < $amount)
{
// do stuff
}

It made a big enough difference on my slow machine to merit me writing
as many loops in this way as I can. (I think.)

[PHP] Making a Session Longer

[Free Grafton]

We offer an application for our customers which allows them to log into
their organization and participate in discussions, register for events and
build their websites. We are using Apache 2.0.47, PHP 4.3.3 and MySQL 4.0.15
for the application. We use session cookies with PHP to establish their
permissions and store other information about them while they are logged in.

The problem we are experiencing is that we are starting to have so many
users on at one time that they are getting bumped off faster and faster. We
have increased the MaxUsers in apache up to 1000, but that doesn¹t seem to
make any difference. Our session_cookie is set to 0 in the php.ini file so
there is no inherent timeout for users. We have 1.5GB of memory on our
production server and aren¹t experiencing any memory swaps, so I don¹t think
that is it as well.

The only other possible thing I can think is that it might be related to
session.gc_maxlifetime =1440 in the php.ini file. I have looked and can¹t
really find much valuable information on what this really does and if it
would have any affect on our sites.

So, if anyone has some advise on what we can try, it sure would be greatly
appreciated. Have an excellent day!
