PHP isset form submission question

dcparham

i simply want to check if when the form is submitted on page1, and then define a session variable and pass it along to be picked up by page2. my simple code is not doing the trick; can someone please help?
"page1":

<?php
error_reporting(E_ALL); 
ini_set("display_errors", 1);
//chg to 0=errorReportingNo; 1 for errorReportingYes. 
session_start();
?>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<?php
if(isset($_POST['submit']))
{
$_SESSION['checkbox1']=$_POST['check1'];
}
?>
sessionTest1.php ---> sessionTest2.php
<form method="post" action="sessionTest2.php">
<input type="checkbox" name="check1" value="1" />
<input type="submit" value="submit" />
</form>

"page2":

<?php
session_start();
echo "<br /><br /><br />";
echo $_SESSION['checkbox1'];
?>

you see - code is bare-bones. what am i missing to get the isset to recognize the form is submitted, then to establish the session variable? thx mucho in advance for your help!

it appears, at a guess, your form is posting to the second script, not the first, and it is the first script that processes the form?

hi CoderDan - thx much for the reply - well, the form's checkbox has a value of 1 that i want to send to the second [or another subsequent] page using a session variable. [page1 sometimes goes to page1b,1c,1d, then to page2; or it can go directly from page1 to page2. so on page2 i am collecting session data from previous pages.] the logic seems so simple. write the form with a checkbox name, and submit button name, then if form submitted, assign session var and transfer to "action" page, in this case page2, where it collects the session variable.

not sure if that answered your question or not. the first script, the "isset" is supposed to be set the session var, then the second script is supposed to know what the var value is.

Well, you need the code snipped (or a function call to it) at start of every page that the form might post to:

if(isset($_POST['submit']))
{
$_SESSION['checkbox1']=$_POST['check1'];
}
