Re: [PHP] convert array to HTML GET request

[hope]

on 2nd page you can use

global $HTTP_POST_VARS; 
print_r($HTTP_POST_VARS);


/// u can use $HTTP_GET_VARS for GET method

regards
hope

if i understand well you need to get an array from html post




if you use the same name for your html fields you automatically have
an array in $_POST



eg



input type=text  name=myfield value="field_1"
input type=text name=myfield value="field_2"



you'll get the array  ar_myfield = $_POS['myfield']



you should achieve the same result using myfield[key] in the name of html

2005/10/2, Martin van den Berg <[EMAIL PROTECTED]>:

Newbe question:

How does one convert an array into a HTML GET request easely? Are
there any standard functions?

Same for HTML POST requests.

Thanks,

Martin.

[PHP] Re: PHP and Active Directory

[Mark Rees]

How do I connect a php script running on linux with Active Directory on
a windows machine? I would like to have my php script autmotatically
read email addresses from the AD server. Can this be done? I've found a
bunch of ldap functions for php but they seem to require ldap to be
installed on linux. I'm confused. Thanks in advance for your help.

I've managed to do it from Windows, after a lot of trial and error, but in
the end it wasn't that complicated.  Have you got any specific questions,
based on following the steps in the manual?

What's the best approach to create a shopping cart.?

I see that you have received some answers already but I wanted to point out
something very obviouslearn how to plan a software application. I know
that I am old school, but I see far too many developers today winging it. A
lot of the reason is that many languages now lend themselves to being
self-taught, and while learning the language is great it is not the only
thing a programmer needs to know about developing software.

A basic flowchart could have helped you to answer your question and broken
down the processes into their componenet parts. Heck, you don't even need
fancy flowcharting software...just write down the steps.

[PHP] Upper case problem

[Merlin]

Hi there,

I am having problems with users who upload text that only contains upper case 
letters. For example "SEARCHING FOR".  Is there a way to detect this via PHP?`
I would like to have the script return him to the form and inform him that this 
is not allowed.

So basicly I need a sort of regex which does detect upper case letters in a row.
Has anybody ann idea how such an regex could look like?

Thank you for any hint,

Merlin

[PHP] session save path

[jonathan]

I'm looking for where apache / php will be saving the user session  
files. when I do a phpinfo(), it tells me that session.save_path will  
be temp but when I look at the files in there, there are only a  
couple of files and they say nwIN;


Is there any way to directly access the session files in this way to  
get at the values?

Now the following would facilitate the action you appear to be

Do you need to decrypt the query string first ?


yes - if you have a query string like

4509134534068953534875104584437043134081743

or whatever then php won't turn it into a $_GET var.
although your query string could contain &'s and/or ?'s and/or ='s
in which case you might have cruft in the $_GET array which you would
want to clean out before extracting your decrypted string into
$_GET ..


decrypt($_SERVER['QUERY_STRING']);
Once you have decrypted it, can you pass it along to a $_GET as you 
would with an unencrypted query string ?

$test = $_GET['test'];
Or, do you need to parse the string to extract variables?


yes you do, but this being php - there is a function that will do it 
for you :-)

many thanks

Here is the method I use:

   $srcimg=imagecreatefromjpeg($path.$files[$i]);
   imageantialias($destimg,true);
   
imagecopyresized($destimg,$srcimg,0,0,0,0,$aspect_w,$aspect_h,ImageSX($srcimg),ImageSY($srcimg));

   imagejpeg($destimg,$dest_dir.$image_name);

imageantialias() might do some good in your case.

Likewise, i had not followed what you were doing with the lines I

"isset" checks that the item with ID $item is in the trolley. No need to
decrease the quantity if it's not there.

> > {
> > $trolley[$item] -= $quantity;

The expression:

$trolley[$item] -= $quantity;

is a short form for the following:

$trolley[$item] = $trolley[$item] - $quantity;

Essentially we decrease the quantity of the given item by $quantity.

Above we check if we subtracted more items than is physically possible
:)

> > unset( $trolley[$item] );

If there are 0 or less items then there's no point having 0 of the item
in the trolley, so we unset the item from the array, which essentially
removes it completely. To view the difference at each step you can do
the following:

";
trolleyPrint();

$trolley[$item] -= $quantity;

echo "Trolley after removing $quantity of $item";
trolleyPrint();

if( $trolley[$item] < 1 )
{
unset( $trolley[$item] );

echo "Trolley after cleaning up empty entry for $item";
trolleyPrint();
}
}

?>

Cheers,
Rob.

Re: [PHP] session_name("CCLTrolley")

Is that over kill? No matter how I slam it, still referring to my 
Frankensteinian merge, "unset" does the job.

http://testesp.flsh.usherbrooke.ca/db/trolley.php
But then again, I will not require a quanity of items. The visitor will 
only want one copy of a bibliographic entry :-\ - I hope?!
You were checking to see if there was a greater than 1 quantity of 
post[RNum], right?

Thanks,
John

Yep the frankensteinian version should work fine if you never want a
quantity greater than one, I was just trying to head off problems before
they occurred, but confused the issue since you don't need quantities :)

I took a look at your link and it appears to be working fine, though you
haven't yet wired up the viewcart.php page :)

[PHP] Making MYSQL's RAND() more random

[Graham Anderson]

what would be the best way to make MYSQL's RAND() more random ?

my random result set always seems pretty predictable.  The first record 
in the result set always seems to be the same 4 tracks :(
Would adding some kind of random seed like RAND($randomNumberGenerator) 
work ?

If so, how do you implement this ?


$sql = "SELECT media.id,
artist.name as artist,
artist.spanish as bio,
artist.purchaseLink,
artist.picture,
media.spanish as trackName,
media.path,
media.quality,
mediaType.id as mediaType
FROM artist, media, playlistItems, mediaType
WHERE playlistItems.playlist_id = $myID
AND playlistItems.media_id = media.id
AND media.artist_id = artist.id
AND media.mediaType_id = mediaType.id
ORDER BY RAND($randomSeed) LIMIT 0, 30";

many thanks in advance

http://dev.mysql.com/doc/mysql/en/mathematical-functions.html:


RAND() is not meant to be a perfect random generator, but instead a
fast way to generate ad hoc random numbers that is portable between
platforms for the same MySQL version.


You might try pulling the results into a PHP array and then use PHP's
random functions instead.  I always got good randomness with
mt_rand().

When I create viewcart.php, what is the best way to extract and display 
the contents of $_SESSION['TrolleyContents'] ?


Do I use my $sql value?
or in my while statement where
$mydata->RNum = $_SESSION['TrolleyContents'][??]] echo $mydata->RNum, 
$mydata->field1, $mydata->field2


Do I implode or explode $_SESSION['TrolleyContents']?

John


$myconnection = mysql_connect($server,$user,$pass);
mysql_select_db($db,$myconnection);
$sql = select * where RNum ... ?
$news = mysql_query($sql1) or die ...
   while ($mydata = mysql_fetch_object($news))
   {
while $_SESSION['TrolleyContents'][??]
echo $mydata->RNum -
   }

echo implode( ',', $_SESSION['TrolleyContents'] );  gives me a comma 
delimited.

Use "foreach" to traverse the array and display each trolly entry nicely
(probably as you do in the search results).

In the search results, I use something longwinded:




You are talking about doing this, below. It looks a little clunky,

foreach ($_SESSION['TrolleyContents'] as $value) {

This might be cleaner? I'm not sure if I'm using while and list right, 
but somehting like that?


$glquery = mysql_query($sql);
while ($mydata = mysql_fetch_object($glquery)) {

 while (list($_SESSION['TrolleyContents'], $value) = $mydata->RNum)
 {
 echo "$mydata->RNum - $mydata->field1: $mydata->field2.";

Believe it or not (you who have not actually used a flowchart for

Another thing I've found is that it's not important to get hung up on

revising it as necessary, putting as much detail as you can.

[PHP] Can I call .html file as a form action instead of .php?

[MI SOOK LEE]

Hello,
Some guy told me that I can call the .html file as a form action instead of 
..php file.

So he said I could do something like this,
echo "Edit";

instead
echo "Edit";

editStaff.html and editStaff.php have the same content, only the file name 
is different. But if I do the former way(call editStaff.html as a form 
action), it doesn't work. It calls some files but looks horrible.

So the advice of the guy was wrong, or did I do something wrong?

Thanks,

This should work fine -- more then likely you do not have your apache (or
whatever web server you use) configured to allow .html files to be parsed as
php files. 

You will need to update your web server configuration.

You can, but unless you configure your web server to consider .html 
files to be PHP scripts, it doesn't make much sense. HTML documents are 
static, so you wouldn't be able to do anything with the data.


Hope that helps.

Two things to add:

1/ Setting your webserver to consider all .html files to be PHP scripts 
is good and bad. It is sometimes considered good because it hides the 
fact that you're using PHP from potential attackers (but they'd have to 
know about a vulnerability in PHP first, so as long as you keep 
up-to-date...), but it's sometimes bad because it causes PHP to process 
all HTML files, even if they don't have any PHP in them, which slows 
things down.


2/ Passing parameters in the query string to a static HTML page can very 
occasionally be useful if you intend to do something with those 
parameters in JavaScript.

[PHP] Handling competing edits in a wiki engine?

[Murray @ PlanetThoughtful]

Hi All,

I've recently been working on building my own wiki engine for my blog
site. While the majority of the engine is complete, a remaining concern
I have is how to handle competing edits (ie when two or more people are
editing the same wiki page simultaneously).

I'm wondering if anyone else on the list has given this some thought?
How would / do you handle competing edits to the same entry in a wiki
application?

Just to add a little extra information: all 'edits' are in fact
'inserts'. Entries are stored in a mysql table. The engine simply
displays the most recent record for the entry being viewed. This is, of
course, to allow for retrieval of an historical version of the entry
should one or more entries be vandalized.

Much warmth,

Murrray @ PlanetThoughftul

Just like Wikipedia -- that is, send a timestamp in a hidden form field 
with the edit box. When the form is submitted, throw an error if there 
is an edit more recent than that timestamp (an "edit conflict").


If your pages have sections, like Wikipedia's, then you can configure 
your software to only throw an error if there is an edit conflict with 
that section.


Also, it's probably a good idea to make use of transactions in an 
ACID-compliant storage engine like MySQL's InnoDB, if possible.

Seems like you have a couple of choices.

1 - Lock the page when the first user edits it until they save their 
changes.  Has the advantage that it's pretty easy code-wise.  The 
disadvantage being that if that first user leaves, but doesn't save/cancel 
his edit, how/when do you decide to release lock?  This would be similar 
to how Visual Source Safe or RCS does it.


2 - Allow shared edits and programatically merge the changes back into the 
master document.  This is how CVS does it.  So you could do something like 
this:


- user A starts editing document.

- user B starts editing document.

- user A saves his changes.  this copy is now the most recent as the 
system would check to see that no changes were made to the "master copy" 
while user A was making changes.


- user B saves his changes.  the system would see that the "master copy" 
had been updated and would merge the changes into B's copy and save that.


In this last step you could do it a couple of different ways.

When user B saves his changes, the system could create a diff file between 
the most recent version of the document and the one that was the basis for 
B's changes -- this would be the changes user A made.  Then you could 
merge those changes into B's document.   If there was a conflict (ie. user 
A and user B made changes to the same line) user B would have to resolve 
the differences.  This is exactly how CVS handles it.


Or, you could just create a diff file and make user B manually apply the 
patch until he's happy.


If you have access to a unix box take a look at the 'diff' and 'patch' 
commands...


good luck!

[PHP] chown function

[Keith Spiller]

Hello,

I'm using:

chown("$endpath", "admin");

to try to change the owner of directories after using mkdir()
to create them.  It continues to fail on my remote Fedora server.

I know the path is correct because mkdir() works perfectly.
Apache sets the owner as 48 when the directory is created.

I am not running in safe mode.

The php.net documentation does not make certain things
clear to me...  For example, do I need to be using a user id
number instead of a name?  Will the chown only work if
the server is setup as a super user?

Any help would be greatly appreciated.

We use a combination of locking the record using a simple boolean column 
together with the user id who has locked the item and the timestamp.


The locking prevents another user from opening the form  and happily 
editing away without realising his changes will be lost when he presses 
submit. The user id is to inform the second user who has opened the 
document, and the timestemp is so that the first guy doesnt open the 
document and go out for lunch leaving it locked. We default it to 5 
minutes after which someone else can open the document and edit it.

Re: [PHP] PHP and Active Directory

[Rory Browne]

Check out the user contributed notes on the manual page - www.php.net/ldap

A few of them refer to Active Directory.

If you installed PHP from source, then you need to install OpenLDAP or
some other ldap package to get the client libraries.

If you installed PHP from packages, then you need to install the
php-ldap package(assuming the functions do not currently work)

If someone else installed PHP, then you need to get them to install
the LDAP extensions to PHP.

Re: [PHP] chown function

Hi Jasper,

When using my Php script, I don't see any error messages.

I have logged in using SSH, but the directories created are
owned by 48 and not my ftp user and so I have to switch
to a super user to make any changes.

Also, even though I use:
mkdir("$endpath", 0777);
The resulting directories end up as 755.

Yeah I have a feeling that you are right, that apache on
my server does not have chown permissions.

Thank you very mych for your help.

I think I'm going to go with Jasper's suggestion, re: simply 
timestamping the current edit from the preceding version and testing 
that timestamp against the existence of more recent edits and throwing 
back to the user a request to resolve their changes against the now 
'current' version.


I had been thinking about a timed locking strategy (5 minutes seems 
short, though, for content creation, and what do you currently do when 
person A comes back from lunch, person B has made an edit in the same 
entry after person A's lock timed out, and person A commits their now 
aged edit? Do you basically throw an error anyway, and ask person A to 
resolve?), and perhaps implementing a simple javascript countdown on the 
page to alert the person editing the page when time for their edit is 
running out, but in all honesty I think throwing back the error, and 
perhaps presenting a diff of the newer version of the entry, and the 
version the user has edited, might be the way to go.


Either way, gives me plenty to think about.

Out of curiosity, does anyone know if it's possible to tell whether an 
individual session is still alive from PHP? I don't mean from within 
code being run for a particular user, but in code that, for example, 
might be executed by a cron job, which would examine a table in which 
session ids have been recorded automatically for each visitor, and 
determining which of those sessions are still theoretically alive? I 
suspect this isn't possible, but I've also learned to never 
underestimate the ingenuity of those faced with things that aren't possible.
