Pass an array to page

Anon

Is there a way to pass an array from a form page to a new page?

Is there someway I can do it with something like
<input type=hidden> or simular?

Tried "PHP Sessions?"

also listboxes are array when passed.

You can do this using input type=hidden if you wish. However, like Nil-Joe says, sessions is the "easy" solutions. If you need to avoid it, you can however try something like this (php4):

foreach ($array AS $key => $val)
print '<input type="hidden" name="array['.$key.']" value="'.$val.'">';

I can't get too technical since you don't say anything about where the array comes from. But I'll try to give you some hints anyway :

1) If the array is from a list of checkboxes or selection box with multiple selections, you will be able to process it as an array

2) If you want to 'store' the contents of an array on a webpage, I suggest you take a look at 'serialize' and 'unserialize' which will 'compress' your array into a string which then can be used as the value of a HIDDEN-type form-element. Then when the form is submitted, use unserialize on the serialized data and - woppie - there's your array! S

Just an idea ...

Thanks for your input guys!

I totally forgot about sessions. I just tried out the sessions way and it's working great!

Thanks Nil & Terje.

Wow, I didn't know about serialize; that's a new function for me. I'll check into that on the php.net page. Looks like it will work though.

Thanks!!

Well, I suggest you don't skip the PHP-manual (especially the online version with comments!)

There's a lot of nice tips and conversations about commands and solutions.

One last thing - before you make your own functions to do something (simple), check out the functions related to your task. There might just be a function to do what you want to do ...

PS : Have you tried http://www.php.net/<function_name> yet? I mean : Which PHP-function do you want to check out today? lol

Hi there,
simple problems have complex solutions.here's the answer to ur querry:
1. In page1.php
.......
$array_to_be_passed[]= "data";
.......
<form action=page2.php>
<input type=hidden name=array_to_pass value='serialize($array_to_be_passed)'>
.......
</form>
ps: remember to send the value in ('') single quotes bcoz if u use ("") then the serialized data doesnt pass.(echo the serialized data, it will have " to seperate the data elements).

2.page2.php
global $array_to_pass ;

$array_to_pass = unserialize(stripslashes($array_to_pass));
for ($i=0; $i< sizeof($array_to_pass); $i++)
echo $array_to_pass[$i];

this will echo u the whole array passed as a hidden field from page1.php.
ps: the array which was serialized in page1.php has slashes. so stripslashes was used in page2.php. again, the whole serialized data is to be deserialized, which restores the array, stored in $array_to_pass.
Happy programmin
