#33759 [NEW]: single POST variable is corrupted
From: kyle dot grieser-c at iovation dot com
Operating system: linux
PHP version: 4.3.11
PHP Bug Type: Variables related
Bug description: single POST variable is corrupted
Description:
------------
A form of type POST that contains a single form element will corrupt the
incoming value.
What I get is this: formvalue="valueformvalue=value"
What I expect is this: formvalue="value"
Yuck! I found a very old bug report consistent with this from 2002 (
http://bugs.php.net/bug.php?id=18648 ) that
suggested adding a hidden form
element like this:
<input type=hidden name=bugfix>
This does indeed fix the problem, but seems like this bug has returned in
a recent version of PHP. Is there a fix?
I could not find any other bugs matching this report, and believe it was
reintroduced with 4.3.11.
Reproduce code:
---------------
<html>
<body>
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$formvalue = trim($_POST['formvalue']);
print "Recieved from Post: '". $formvalue."'";
}
?>
<form action="#" method="post">
<p>
FORM VALUE:<br><br><input type="text" name="formvalue"
value=""
size="50" maxlength="50"></td>
<input type= submit value=submit>
</p>
</form>
</body>
</html>
Expected result:
----------------
I expect this:
formvalue=value
Actual result:
--------------
I get this:
formvalue=valueformvalue=value
