Problems passing a serialized array in a session variable

[gszauer]

Hi all, i have a multidimentional array i want to pass as a session variable.
Of course i serialized the array.
I have 2 files, set.php & get.php
set.php populates the array, and get.php prints it out. below is my code:

Set.php:

PHP Code:

<?php
session_start();
$array = $_SESSION['array'];

if ($array) {
    $associative = unserialize($array);
    print "Array Exists <br />";
} else {
    $associative = array();
    print "Array Created <br />";
}

$associative[0] = array();
$associative[1] = array();
$associative[2] = array();
$associative[0][0] = "0-0";
$associative[0][1] = "0-1";
$associative[1][0] = "1-0";
$associative[1][1] = "1-1";
$associative[2][0] = "2-0";
$associative[2][1] = "2-1";


$_SESSION['array'] = serialize($array)
?>

Get.php:

PHP Code:

<?php
session_start();
$array = $_SESSION['array'];

if ($array) {
    $associative = unserialize($array);
    print "Array Exists <br />";
} else {
    $associative = array();
    print "Array Created <br />";
}

for ($i = 0; $i < count ($associative); $i++){
    print "Associative array: ".$associative[$i];
    print "Subarray1: ".$associative[$i][0];
    print "Subarray2: ".$associative[$i][1];
}

?>

So i navigate to set.php, then to get.php but nothing prints....
What am i doint wrong?

Do you have display_errors on? It would seem to me that you have a fatal error somewhere and are not receiving the error message because this is turned off.

Check this tutorial:

This is good also Jordan but it would be easier to just use

PHP Code:

ini_set("display_errors", true); 


or

PHP Code:

ini_set("display_errors", "1"); 


and if you want to turn errors off you can delete that line or change true to false and 1 to 0

Nope, not the problem.
I re-vamped the code, now when i refresh the page it should show me a new entery...

PHP Code:

<?php
ini_set("display_errors", true); 
session_start();
// id, and color_selection are passed via the $_GET method

print "--- Debug info ---<br />";
print "Passed color: ".$_GET['color_selection']."<br />";
if ($_SESSION['color']) {$color = unserialize($_SESSION['color']); print "Color array loaded <br />";} else {$color = array(); print "Color array created <br />";}

for ($i = 0; $i < count ($color); $i++) {
     print "<br />--- Reading Array <br /> Index: ".$i."<br />ID: ".$color[$i]["id"]."<br />Value: ".$color [$i]["value"]."<br />";
}

$arraySize = count ($color);
$color[$arraySize] = array();
$color[$arraySize]["id"] = $_GET['id'];
$color[$arraySize]["value"] = $_GET['color_selection'];
print "<br />--- Writing to Array --- <br />Index: ".$arraySize."<br />ID: ".$color[$arraySize]["id"]."<br />Value: ".$color [$arraySize]["value"]."<br />";

$_SESSION['color'] = $color;

?>
