Missing something in passing form variables

[Mike Wilcox]

I have the following code to select an item from a drop down menu and
call the same script over again. I am expecting that after the first
time the script is run the first echo would produce the selected PBX
name (e.g. FMSite) but instead I get FMSitepbx=FMSite.

Needless to say this screws up the further processing I want to do. What
I really want to do is set a cookie containing the selected PBX name so
other scripts can get the cookie and provide specific data.

Thanks,

Mike
<?php
echo($_POST['pbx']);
$dbcnx = @mysql_connect("localhost", "***", "**********");
if (!dbcnx){
echo( "<p>Unable to connect to database.</p>");
exit();
}
if ( !@mysql_select_db("inet") ) {
echo( "<p> Unable to locate the iNet database. " . mysql_error() .
"</p>" );
exit ();
}

$query = 'Select Name from PBX order by Name';
$result = mysql_query ($query)
or die ('Query Failed');
echo '<form action="setpbx.php" method="POST">';
echo 'Select PBX <select name="pbx">';
while ($row = mysql_fetch_array ($result)) {
echo '<option value="' . $row['Name'] . '">' . $row['Name'];
}
echo '</select>';
echo '<input type="submit" value="Submit">';
echo '</form>';

Try this instead:

echo ' *** ', $_POST['pbx'];
My suspicion is that the "FMSitepbx=" is written before your script
reaches that particular point (and maybe this proves me right).

maybe a bad html construction
you should verify your 'pbx' value in your html page
by reading your html source code

No space here? ?!?!?!

Can we have a look at your site to see the HTML generated?

while ($row = mysql_fetch_array ($result)) {
echo '<option value="' . $row['Name'] . '">' . $row['Name']; /* it doesn't matter, but I'd add */

what happens if you change the name of your <select> ?

Changed the name of the <select> to "node" and the echo to $_POST["node"]
and now the output is FMSitenode=FMSite

Instead of the echo $_POST["node"], try

echo '<pre>';print_r($_POST);echo '</pre>',"\n";

Which will show you what's in the $_POST array. That may give you a
hint as to what is going on. If the value is correct there, recheck
your code.

^^^^^^
$_POST['pbx']

Ah! Maybe I see what is hapenning now :-)

Try replacing the "echo($_POST['pbx']);" at the top of the script with

echo $_POST['pbx'], ' *** ';

and if the output is

FMSite *** pbx=FMSite

that proves the $_POST['pbx'] is behaving :-)
and that your problem lies elsewhere.

To find where is the problem put a few/lot of

echo '<p><b>* ', __FILE__, '/', __LINE__, ' *</b></p>';

inside your code until you spot the error.

he he...
FMSite (the first occurence) is the value expected (in <option...>)
node=FMSite is the value sent by the form in his header (name and value
of the select element :
.. Content-Type: application/x-www-form-urlencoded
.. Content-Length: 10
.. node=FMSite
as Ken said, there is something wrong in your POST array
is your Register Globals ON or OFF ?
what is your version of php ?

is the output (html source) only :
FMSitenode=FMSite<form action...

or, as you said in a previous post
<Xn*********************************@10.7.208.6> :
FMSitenode=FMSite end <form action...
..................^^^^^

(funny challenge...)

PHP version is 4.2.2, Apache is 2.0.40.

Contents of the array is: [node] => FMSitenode=FMSite

Globals were turned on so I turned them off, no change in the output.

Does it also happen with GET method?

Try it!
change the form method to get and print $_GET['node'].

When you POST the GET (lol) what shows up in the address bar of the
browser?

Are you sure you do only have a single script running?
No auto_append_file, no auto_prepend_file?
No user-defined error_handling function set up?

hmmmm...

I think (at this time) there is something in your script (and in its
includes or requires if there are) that corrupt (rewrite, redefine,
reaffect...) your $_POST array.

but you tried pedro's script too...
so maybe there is a problem in your configuration.

but, in this case, this problem should affect your others scripts...
it's very strange.

Using GET is works correctly!! Changing back to POST will break it
again. Is auto_append_file auto_prepend_file httpd or PHP?

What about error handling?

Try this right before your echo $_POST['whateber']:

<?php

}

$old_eh = set_error_handler('my_error_handler');

Nothing working yet. It does work if I change to get instead of post, so I

That Did It!!! (Putting in an extra field, that is.) Perusing the bug,
it didn't look like it is actually fixed yet and may actually be related
to Apache 2.

Thanks to you and denisb for all of your help, I appreciate it.

the use of Apache 2 is still not recommended in production...
