[PHP] Whats wrong?
Whats wrong with this where $senderemail = $_POST['from']; It doesnt It only echos thank you. Why?
Re: [PHP] Whats wrong?
Hey, Just touched it up a bit but its working: This should come before: $senderemail = $_POST['from']; not after this: print "Thank You, $senderemail"; plus I'm guessing that either your form is sending $senderemail or that you are getting via a $_GET you have to post $from not $senderemail.

[PHP] For Loops and Variables??
When I use for loops, at the start of each iteration, the variables hold the values from the last loop. First, is there an elegant way of clearing variables at the start of each loop rather than using unset???! It just seems wrong. Also, all my problems would be solved if variables in a for loop were kept local, but everything by default is a global. Can I change this in php.ini or something??

[PHP] Using Image/GD functions to transform images stored in database
I'm new to the GD/Image functions with PHP, and I'm trying to use them to manipulate jpeg images that I've stored in a MySQL database (specifically, creating thumbnails). The thing I can't tell from reading the documentation is how to use these image functions to operate on image data -- it looks like you get a GD image resource in each case by specifying a file name, not by passing image data directly. While I can see how that's convenient for the common case, I can't figure out how to make this work without writing the image out to a file (and since I'm already taking a bit of a performance hit by reading the image out a database, that seems like the wrong thing to do). Can anyone elaborate? Thanks, Weston -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] square brackets in form names violate HTML specs?
Something I've noticed in PHP is a proliferation of code like this:
According to the specs, the square brackets in "stuff[title]" are
technically illegal.
http://www.w3.org/TR/html4/types.html#h-6.2
ID and NAME tokens must begin with a letter ([A-Za-z]) and may
be followed by any number of letters, digits ([0-9]), hyphens
("-"), underscores ("_"), colons (":"), and periods (".").
Thoughts? Suggestions for writing flexible PHP code that at least
passes the HTML 4.01 Transitional DTD?

[PHP] htmlentities() and the macintosh character set
Hello- I have a request but don't know where to send it. Thus, it ends up here. Alternately, I'm looking for some solutions: The request: Can the macintosh character set be added as an option for htmlentities() and other commands? That would be so helpful for our mac-based company. The problem: I'm fairly new to php and have found that the macintosh character set is pretty different from other standard sets, so when someone in our company enters an em-dash (an extended dash, that would be represented as &emdash; in html) into our SQL database, browsers display it as Ñ (Ñ) because that's the correct mapping in other, standard sets. Of course, I could do a replace on that character, but there are another 6 characters that I know of that will cause problems, and probably more beyond that. The quick and good way is to convert with htmlentities(), but the mac charset is lacking. Any suggestions how to fix this?

[PHP] socket_write eats data
Hi,
I am deveoping a chatserver in IRC-style in PHP. For communication it uses
socket-multiplexing aka socket_select. So long so good, works perfectly.
The problem is, than when i make several socket_write's to the same client
without waiting about 0.1sec after each write, the written data gets lost
somewhere. socket_write does NOT throw any error, the data seams just
sended, but the clients never receives it.
Small example of the used code:
-
var $clients // array of 'client'-objects, each object has it's own
socket-descriptor in the object-variable $socket
function write_to_clients ($text) {
for ($i = 0; $i < count ($this->clients); $i++) {
socket_write ($this->clients[$i]->socket, $text);
}
// usleep (1); if this is uncommented, all write are received by all
clients
}
for ($i = 0; $i < 10; $i++) {
$this->write_to_clients ("test ".$i);
}
-
Okay, this doesn't check the client-sockets for readiness to write, but even
if I check (via socket_select), ALL clients are ready to write and writes
get lost too. It can't be the network-connection, because the tests run with
standalone PHP-clients on the same machine.
Is there any possibility to make fast writes without waiting after each
write? The wait limits the server to max. 10 writes per second, wich isn't
really enaugh for a good chatserver.
Thanks for your help!

Re: [PHP] socket_write eats data - solved
Hi,
i've checked a hundred things before posting this question, but i forgot the
most important thing, the buffer.
The 'eaten' writes were buffered by the network-kernel and sent as bunch of
data. If too much data for the buffer is sent, the write is broken up and
completed in the next bunch-of-data.
My receive-script hasn't diplayed the raw output, but an unserialized array,
fetched out of the received string.
Maybe this will will help someone in future.

Wouldn't =& still be legal because you are assigning a reference of what
is returned? Would that make $some_object a reference to a reference? It
doesn't seem to raise an exception.

Subject: Re: [PHP] Session stealing, ..
I wrote a custom session handler that encrypts the session before it is
stored in /tmp that way even if someone has access to the session files
they are useless.
It stores the randomly generated encryption key on the user's client
base64_encoded, which can be intercepted as well all know but it still
increases the difficulty of reading the /session files now they must
have access AND sniff the encryption key. Additionally for the more
secure sites I require the user access the site through SSL so the
cookie is not passed in plain text.
If you are interested I'll see if I can send it to you, it uses my Crypt
Class (PHP class simplifying Mcrypt usage).

[PHP] MySql Query Help: COUNT()
Hello everyone!
I'm trying to get the total number of a certain records from a database,
but the result is always '1'. Please advise!
=MySql Table =

-total number of projects per employee
I currently have
$_sql = "select count(*) as TotalRecords, count(employee_id) as
TotalEmployees, count(project_id) as TotalProjects GROUP BY employee_id,

[PHP] Text into a url
Hi
I am havening a problem retrieving url from a mysql database. I have the
url's stored as text and am using the following code to retrieve them
$query = "SELECT name,url FROM clubs WHERE url>'' ORDER BY name";
$result = @mysql_query($query) or die ("Query failed");
if (mysql_num_rows($result) == 0) {
print "No Club Links Found.";
} else {
while ($row = mysql_fetch_assoc($result)) {
print $row["name"] . "";
This seems to work except the url refers to the previous name on the list
produced with the first name as a blank url.
Can anybody help

You have incorrect HTML. You're last line should look like this:
print "{$row['name']}";
You were starting your link after you printed out the value, without
ending the link, so it continued to the next item and only ended when
the next link started on the next row.

[PHP] More Image Transformation Difficulty
I'm trying to write a script that pulls an image from a database and transforms
the size if passed a width via the url query string.
Thanks to the helpful hint about the function "imagecreatefromstring", I
think I'm now able to ready image data I've pulled for a database with
GD. However, I'm still having trouble resizing... at least, when I'm
sending the image to my browser, I'm being told that it "cannot be
displayed, because it contains errors." (And the script does work if
I don't try resizing... see below for example URL).
Here's what I'm doing:
$row = mysql_fetch_row($dbresult);
$imgdata = $row[0];
if(isset($width) && !empty($width) && is_numeric($width))
/* only do transformation if given a width */
{
$gdimg = imagecreatefromstring($imgdata);
$srcWidth = imagesx($gdimg);
$srcHeight = imagesy($gdimg);
$scaleFactor = $width/$srcWidth;
$targetHeight = $srcHeight * $scaleFactor;
$resizedimg = imagecreatetruecolor($width,$targetHeight);
imagecopyresized($resizedimg,$gdimg,0,0,0,0,$width,$targetHeight,$srcWidth,$srcHeight);
}
header("Content-Type: image/jpeg");
header("Content-Transfer-Encoding: binary\n");
//send file contents
if(!empty($resizedimg))
imagejpg($resizedimg);
else
{
header("Content-length: " . strlen($imgdata) . "\n");
print($imgdata);
}
Does anyone see what I'm doing wrong? Again, the script actually works if I
don't try to do the transform. See:
http://www.fsboutah.net/jpg.php?table=homes&key=4&field=Picture1
and
http://www.fsboutah.net/jpg.php?table=homes&key=4&field=Picture1&width=100
for contrasts.

//output
echo $_res->TotalRecords; //prints nothing
echo $_res->TotalEmployees; // returns 1
echo $_res->TotalProjects; //also return 1
Your query doesn't even have a "FROM Table" in it. Hopefully that's just
a cut and paste error, as you should see your "die" message because of
that error.
You're not going to get the results you're after with a single query
(unless you have PHP do some of the counting). Look at using a couple
different queries to get your count.
One solution may be:
SELECT employee_id, COUNT(*) AS NumProjects FROM activity GROUP BY
employee_id;
The number of rows returned will be the number of employees. Each row
will list the employee_id and how many times it appeared in the table.
If project_id is not repeated for a given employee_id, then this will be
your project count. As you loop throught the results, keep a running
total of the NumProjects column to get the total projects.

Whats wrong with this
where
$senderemail = $_POST['from'];
It doesnt It only echos thank you.
Why?--- End Message ---
--- Begin Message ---
Hey,
Just touched it up a bit but its working:
This should come before:
$senderemail = $_POST['from'];
not after this:
print "Thank You, $senderemail";
plus
I'm guessing that either your form is sending $senderemail or that you are
getting via a $_GET
you have to post $from not $senderemail.
If you change the above to a $_GET this will work
YourFileName.php?from=Ryan

Subject: [PHP] socket_write eats data
Hi,
I am deveoping a chatserver in IRC-style in PHP. For communication it uses
socket-multiplexing aka socket_select. So long so good, works perfectly.
The problem is, than when i make several socket_write's to the same client
without waiting about 0.1sec after each write, the written data gets lost
somewhere. socket_write does NOT throw any error, the data seams just
sended, but the clients never receives it.
Small example of the used code:
-
var $clients // array of 'client'-objects, each object has it's own
socket-descriptor in the object-variable $socket
function write_to_clients ($text) {
for ($i = 0; $i < count ($this->clients); $i++) {
socket_write ($this->clients[$i]->socket, $text);
}
// usleep (1); if this is uncommented, all write are received by all
clients
}
for ($i = 0; $i < 10; $i++) {
$this->write_to_clients ("test ".$i);
}
-
Okay, this doesn't check the client-sockets for readiness to write, but
even
if I check (via socket_select), ALL clients are ready to write and writes
get lost too. It can't be the network-connection, because the tests run
with
standalone PHP-clients on the same machine.
Is there any possibility to make fast writes without waiting after each
write? The wait limits the server to max. 10 writes per second, wich isn't
really enaugh for a good chatserver.
Thanks for your help!

Re: [PHP] socket_write eats data - solved
No, it's TCP and a very uncomplicated protocol, everything is sent in clear
text. Major problem is the socket-multicasting to keep track of all clients
simultanly.

I almost fell for this and updated my code. Then I decided to read the
spec for myself and noticed that it doesn't say anywhere that % is ok
either *grin*.
- ID and NAME tokens must begin with a letter ([A-Za-z]) and
may be followed by any number of letters, digits ([0-9]),
hyphens ("-"), underscores ("_"), colons (":"), and periods
(".").
Cheers,
Rob.

No, only the button that is clicked will be set.

I wouldn't rely on Javascript...

Re: [PHP] Calling functions from Button actions
apologies i generally use this system for deleting records, i give a
confirm box if they press ok it goes to another action, i suppose i should
change this system to submit the form instead and check for the post var ?
i guess at least it could store the http_referer then :\

Re: [PHP] Calling functions from Button actions
my form action usually looks like this some.php?action=update&ID=1 my update will look like update table set *** where _rowid=$_GET['ID'] so therefore its globally used. i'd use the id from the get var but i guess in the delete function i could place this within the update action so case 'update': delete(tablename); update(tablename); break; i dont tend to like this becuase it'll be in the same action which is why i tried the location.href way to send it to a different action, as both the update and delete buttons are within the same form, i'm sure u could have a delete button in a list although this leads to problems as users generally would like the delete button in the update/view screen so they know exactly what they are deleting so therefore which is why the buttons are in the same form, any ideas ? > [EMAIL PROTECTED] wrote: > >> apologies i generally use this system for deleting records, i give a >> confirm box if they press ok it goes to another action, i suppose i >> should change this system to submit the form instead and check for the >> post var ? i guess at least it could store the http_referer then :\ > > If you're talking about presenting a list of records and using a button > to delete a record, then you should use a method such as this... > > > > Where "xx" is the record_id (or equivalent).

Re: [PHP] socket_write eats data - solved
Wouldn't this multiple connections be a problem for php? IMHO one of the
main draw backs of the PHP IMAP library is the fact that you have to
open and close and imap connection for each page. That issue is
multiplied ten fold in this scenario isn't it?

The 'eaten' writes were buffered by the network-kernel and sent as bunch

completed in the next bunch-of-data.
My receive-script hasn't diplayed the raw output, but an unserialized

fetched out of the received string.
Maybe this will will help someone in future.

Subject: [PHP] socket_write eats data
Hi,
I am deveoping a chatserver in IRC-style in PHP. For communication it
uses
socket-multiplexing aka socket_select. So long so good, works perfectly.
The problem is, than when i make several socket_write's to the same
client
without waiting about 0.1sec after each write, the written data gets
lost
somewhere. socket_write does NOT throw any error, the data seams just
sended, but the clients never receives it.
Small example of the used code:
-
var $clients // array of 'client'-objects, each object has it's own
socket-descriptor in the object-variable $socket
function write_to_clients ($text) {
for ($i = 0; $i < count ($this->clients); $i++) {
socket_write ($this->clients[$i]->socket, $text);
}
// usleep (1); if this is uncommented, all write are received by
all
clients
}
for ($i = 0; $i < 10; $i++) {
$this->write_to_clients ("test ".$i);
}
-
Okay, this doesn't check the client-sockets for readiness to write, but
even
if I check (via socket_select), ALL clients are ready to write and
writes
get lost too. It can't be the network-connection, because the tests run
with
standalone PHP-clients on the same machine.
Is there any possibility to make fast writes without waiting after each
write? The wait limits the server to max. 10 writes per second, wich
isn't
really enaugh for a good chatserver.
Thanks for your help!

[PHP] change PHP include directory
Hi, Normally to change a sites include directory for PHP I'd use a .htaccess file and the following command: php_value include_path ".:/path/to/web/" Again normally, I would get the path to the site by doing a simple phpinfo(); command and find the _ENV["DOCUMENT_ROOT"] line near the end of the phpinfo(); page. I've just setup an account with a shared hosting provider - I'm not fully sure if they allow me to use .htaccess or not, I've got a call into tech support but waiting is boring. So while I wait - is there a better or more accurate way of determining the actual path to my site on their server? I'm sure it has been written into PHP to specifically not allow this - just curious. Secondly, if it is proven that my host does not allow .htaccess - is there another way for me to change the include directory from its default and into my sites root? This current site isn't all that large, so I could live without changing the include path - but my next job (which is already committed to this same host) is fairly large and will be a necessity for the change to occur.

You can do this at the top of each page if all else fails
ini_set('include_path','new_include_path:'.ini_get('include_path'));
(Use a ; as the separator if on windows)
This puts your directory first in the search path
