checkboxes and sessions nightmare

[sjlsam]

i have a checkbox that i want to set a session variable based on whether it is selected or not, i have tried ALL the following, and for whatever reason it makes the session variable off for all of them (even if $_POST[$indie] == 'on'!!)

 

what am i doing wrong?

 

 

ATTEMPT 1:

if( $_POST[$indie] == 'on' ) { $_SESSION['indie'] = 'on'; } else { $_SESSION['indie'] = 'off'; }

 

RESULT:

$_SESSION['indie'] always returns as 'off' even when $_POST[$indie] returns as 'on'

 

---

 

ATTEMPT 2:

if( isset($_POST[$indie]) && $_POST[$indie] == 'on' ) { $_SESSION['indie'] = 'on'; } else { $_SESSION['indie'] = 'off'; }

 

RESULT:

$_SESSION['indie'] always returns as 'off' even when $_POST[$indie] returns as 'on'

 

---

 

ATTEMPT 3:

if( isset($_POST[$indie]) ) { $_SESSION['indie'] = 'on'; } else { $_SESSION['indie'] = 'off'; }

 

RESULT:

$_SESSION['indie'] always returns as 'off' even when $_POST[$indie] returns as 'on'

Have you instered session_start() at the beginning of your file?

thanks for your reply, i have made some more adjustments to my code, but it seems that Corp is always on and can never be turned off

i think there is something wrong with my logic

 

what i am trying to accomplish here: i want indie and corp to be passed as a session, but if there is no session present the sessions need to be created based on the user's selection

 

i have been trying to figure out this problem on and off for a month!

 

 

here's my code:

 

PAGE 1

<?php

session_start();

session_register("SESindie");
session_register("SEScorp");

/* GRABBING THE VARIABLES FROM SESSION OR POST */

if (isset($_REQUEST["FRMindie"]) or isset($_REQUEST["FRMindie"])) {
if($_REQUEST["FRMindie"] != "on")	  { $indie = "off"; } else { $indie = "on"; }
if($_REQUEST["FRMcorp"] != "on")	   { $corp = "off"; } else { $corp = "on"; }

/* pass the selection to the session variables */
$_SESSION["SESindie"] = $indie;
$_SESSION["SEScorp"] = $corp;
}
else
{
$indie = $_SESSION["SESindie"];
$corp = $_SESSION["SEScorp"];
}

/* QUERY THAT RUNS  BASED ON YOUR SELECTIONS */
$query = "SELECT * FROM restaurants";
$isfirst = 1;

if($indie=='on'){
if($isfirst == 1){ $query .= " WHERE "; $isfirst = 0; } else { $query .= " AND "; }
$query .= "restaurants.restIndependent = 1";
}

if($corp=='on'){
if($isfirst == 1){ $query .= " WHERE "; $isfirst = 0; } else { if($indie == 'on') { $query .= " OR "; } else { $query .= " AND "; } }
$query .= "restaurants.restIndependent = 0";
}

/* CODE FOR CHECKBOXES */
echo "<form name='search' action='./sessions.php' method='post'>";

/* INDIE CHECKBOX */	
echo "Indie <input name='FRMindie' type='checkbox' onchange='this.form.submit()'";
if ($indie == "on"){ echo " checked='checked' "; }
echo "/>  -  ";

/* CORP CHECKBOX */
echo "Corp <input name='FRMcorp' type='checkbox' onchange='this.form.submit()'";
if ($corp == "on"){ echo " checked='checked' "; }
echo "/>";

echo "</form>";

/* DEBUG */
echo "<div style='background:lightgrey; width:400px;'><strong>DEBUG</strong>";

echo "<br /><br />QUERY: $query<br /><br />";

echo "SESSION indie: " . $_SESSION["SESindie"] . "<br />";
echo "SESSION corp: " . $_SESSION["SEScorp"] . "<br /><br />";

echo "FORM indie: " . $_REQUEST["FRMindie"] . "<br />";
echo "FORM corp: " . $_REQUEST["FRMcorp"] . "</div><br /><br />";

echo "<a href='sessions_forward.php'>Change page</a>";

?>

 

PAGE 2

<?php session_start(); ?>

You went forward!<br /><br />

<?php echo "Indie: " . $_SESSION["SESindie"]; ?>

<br />

<?php echo "Corp: " . $_SESSION["SEScorp"]; ?>

<br /><br />
<a href="sessions.php">Back</a>

Try this:

<?php
/* INDIE CHECKBOX */	
echo "Indie <input name='FRMindie' type='checkbox' value='on' onchange='this.form.submit()'";
if ($indie == "on"){ echo " checked='checked' "; }
echo "/>  -  ";

/* CORP CHECKBOX */
echo "Corp <input name='FRMcorp' type='checkbox'value='on'  onchange='this.form.submit()'";
if ($corp == "on"){ echo " checked='checked' "; }
echo "/>";
?>

 

And another thing. $_REQUEST does not consist $_SESSION variables. It consisting $_GET, $_POST and $_COOKIE variables.
