Form Variables

nalleyp23

Can someone please help me understand how variables are passed in PHP now. I used the language a couple of years ago and after a database insert you only had to put the $variablename and you had it on the next page.

However, now it doesnt show.. I have a form that is inserting into a MySQL database with POST method. I have tried getting the values of my form variables on the next page from:

$POST
$REQUEST
$_HTTP_POST_VARS

Everything..

PLEASE HELP!!!!!

Humbly,

Yeah, I had the same problem. Try this;

<form action="nextpage.php" method=POST>
<p>Please enter your User iD:<br></p><p>
User ID:
<input type=text name="userID" size=6 maxlength="6">
<p>  </p>
<table width="15%" border="0">
<tr>
<td width="40%">
<input type=submit name="submit" value="Done">

---------------------------------------Now the next page-------------------
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<?php
print $userID;

echo $_GET['userID'];
?>
</body>
</html>

Your problem depends on the version of php you are using. Also when you used php in the past $register_globals was turned on by default. This allowed you to access the form input $username. It is now turned off by default for security reasons.

When submitting a form VIA POST (ie method="POST")
$HTTP_POST_VARS['username'] (Should work up to current version of php)
Not $HTTP_POST_VARS
or $POST['username']

your code won't print anything when you type echo $_GET['userID']; because the submit method was POST. Maybe it was a typo
