HTTP_POST_VARS help

visiblyConfused

This is my form code:

<?php

$type = 2;
.....

?>
</form>

And this is searchresult.php:

<?php
if ($HTTP_POST_VARS["type"] == 2)
echo 'reports';
else if ($HTTP_POST_VARS["type"] == 1)
echo 'students';
else
echo 'nothing';
?>

I get the mesage:

Undefined index: type in C:.........searchresult.php pn line 9

I tried setting Register_Globals to On, and just call $type, but I'd get the same error. Since there is no track_vars setting in my php.ini, iassume it's always on.

I'm using PHP 4.3.2 on WinXP, using DzSoft PHP Editor's built-in http server on a single machine.

I have another problem which might be unrealted, but sometimes, the editor will take forever when loading the forms, eventually giving me a timeout error, and then I'd see an illegal memory reference error cause bythe editor.

Anybody knows why i got these problems?????

Also, I already tried using $_POST("type"), and using single quotes on both methods but still won't work.

Forms POST the content of the form fields. If you want to pass the $type variable to "searchresult.php", you should do this (in HTML, convert to PHP echo() if desired)...

<input type=hidden name=type value=2>

prior to closing your <form> tag...

HTH, 🙂

OK, so I have this:

<?php
include('db_connect.php');
$type = 1;
echo $type;
?>
<table>
<tr><b>-- STUDENT SEARCH -- </b></tr>
<tr bgcolor=#ff0000>
<td><b>Student ID</td>
<td>Last Name</td>
<td>First Name</td>
<td>Room</td>
<td>Status</b></td>
</tr>
<tr>
<td width=150 align=center><input type="text" name="SID" size=24 maxlength=9></td>
<td width=150 align=center><input type="text" name="Lname" size=24 maxlength=20></td>
<td width=150 align=center><input type="text" name="Fname" size=24 maxlength=20></td>
<td width=150 align=center><input type="text" name="RoomID" size=24 maxlength=9></td>
<td width=150 align=center><input type="text" name="isStudent" size=24 maxlength=1></td>
</tr>
</table>
<input type=submit value="Search">

<input type=hidden name=type value=1>

</form>

and searchresult is:

<?php
if ($type == 2)
echo 'reports';
else if ($type == 1)
echo 'students';
else
echo 'nothing';
?>

ANd still getting the same error🙁
But, I think I do understand that HTTP_POST_VARS will only look at the type=submit variables, right?:p

Thanks for your help, BTW😉

Well, you're part way there ... lots to remember when you're starting out... 😉

<?php 
if ($_POST['type'] == 2) 
echo 'reports'; 
else if ($_POST['type'] == 1) 
echo 'students'; 
else 
echo 'nothing'; 
?>

It will only look at variables in the form that has method set to POST. I believe that, as we see here, they must be in HTML <input> tags, but it's Sunday, and I'm not headed over to the manual to see if I'm right 😉
