Passing arrays around with forms

[Anon]

Here's the goal: To convert an array to a value passed in a form input type=hidden, and then convert it back to an array at the target page.

$obj is an array, with a variable number of
values stored.

I want to pass it, the whole thing, via an input form to another page, intact.

Here's what I've got so far trying to break it down:

ONE.PHP:
<?php

$obj[name]="Ben";

$obj[number]=1;

$objpass=serialize($obj);

$objpass=addslashes($objpass);

echo "<form method=post action=two.php>
<input name=objpass type=hidden value=$objpass>
<input type=submit>
</FORM>
";

?>

And now for page two.php:

TWO.PHP:

<?php

$obj=stripslashes($objpass);

echo $obj;

$obj=array(unserialize($obj));

?>

But this doesn't work! The output of page two is:

obj🅰2:{s:4:\"name\";s:3:\"Ben\";s:6:\"number\";i:1;}aa

But the form input from one.php is:

a:2:{s:4:\"name\";s:3:\"Ben\";s:6:\"number\";i:1;}

It seems that the main difference is that "obj" at the beginning and the "aa" at the end. How do I convert this back to an array that I can use?

Thanks guys, all of you have been immensely helpful!

Use urlencode and urldecode instead of addslashes and removeslashes to transport values from one script to another. Also there is no need to re-create array again in your unserialize function. So it might look like this:

Your first script:

$obj = array();
$obj[name]="Ben";
$obj[number]=1;

$objpass=serialize($obj);
$objpass=urlencode($objpass);

and second:

$obj=urldecode($objpass);
$obj=unserialize($obj);

Hope it helps...
