Form and session variables not passing correctly

Chris-the_dude

Hello PHP gurus,

I'm having a problem getting both my form variables and session variables to pass to the next page. In fact they will not pass at all. I've done some searching on my problem, and can't seem to come up with anything.

the first page, cgitest.php, is a form. when the submit button is pressed, we go to cgitest2.php, yet no variables are passed. cgitest2 just displays: "variables not passed"

cgitest.php

<?php
session_start();
session_register('valid user');
$vartest = "ugly";
?>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<form action='cgitest2.php' method=post>
<table>
<tr>
<td>Input1:<input type='input1' size=30></td></tr>
<tr><td>Input2:<input type='input2' size=30></td></tr>
<tr><td><input type='submit' value='Submit'></tr></td>
</table>

cgitest2.php

<?php 
session_start(); 
?>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<?php

if (!$input1 && !$input2)
	echo "variables not passed";
echo $input1."<br>";
echo $input2."<br>";
echo $vartest;
?>

</body>
</html>

I can supply the contents of my phpinfo page if neccessary. thanks

Sorry Chris, but there is a lot wrong with your code. First lets look at your html ...

sould be

now, do you have registered globals on or off?

try this instead on your second page...

if ((!empty($POST["input1])) && (!empty($POST["input2])))

next do some reading on session variables, because you are not using them correctly!

Cogen

Opps, I guess to be similar to your structure it wouldn't be ...

!empty()

just empty()

Any way, the point was to use $_POST

Chris-the_dude

I checked and yes, register globals is off

I fixed my code up like you suggested - using $POST, but it is still exhibiting the same behavior. IT is saying that $POST['input1'] and $_POST['input2'] are empty.

here's the new code from the second page:

<?php

if ((empty($_POST['input1'])) && (empty($_POST['input2'])))
	echo "variables not passed";
echo $_POST['input1']."<br>";
echo $_POST['input2']."<br>";
//echo $vartest;
?>

try using

<?
if ($_POST['input1'] && $_POST['input2'])
{
echo $_POST['input1'] . "<br>";
echo $_POST['input2'] . "<br>";
echo $_SESSION['vartest'] . "<br>";
}
?>

stolzboy, when I try your code I get no output- just like I expected

stolzyboy

whatta mean

"just like I expected"

that will work, no ifs and or buts

as long as you have both input1 and input2 filled out and they are
named name="input1 and name="input2" and your form is posting

Chris-the_dude

Alright, I got the form variables working with $_POST.
It wasn't working after the changes because of a syntax error on my part. my appologies.

If I seem dense about the sessions and form variables here, its because I have come from an environment where register globals is enabled, and I'm having to learn to do without it now. I didn't think it would make such a big difference.

Thanks for the help
