Pass array in hidden field

[damiantaylor]

Hi all!
I'm trying to pass an array as a hidden field from a form in the URL of the browser but it's not working.
Can you tell me what is wrong with this...it's my first attempt so be gentle :)

The form HTML is

<form name="filter" action="http://www.myurl.com" method="get">

<input type="hidden" name="main_page" value="index" />
<input type="hidden" name="Flt_Grade[]" value="100" />

<select name="filter_id" onchange="this.form.submit()">
 <option value="1">Most Popular</option>
 <option value="2" selected="selected">Price: Low to High</option>
 <option value="3">Price: High to Low</option>
 <option value="4">Title</option>
 <option value="6">Date Added: Newest</option>
 <option value="7">Date Added: Oldest</option>
</select>
 
</form>

I would expect, when option 4 in the dropdown is selected the URL to be
www.myurl.com&main_page=index&Flt_Grade%5B%5D=100&filter_id=4

Where %5B = [ and %5D = ]

But what I actually get is
www.myurl.com&main_page=index&Flt_Grade=&filter_id=4

The Flt_Grade array is not passed properly.

Can this be done so the hidden field is passed in the URL as an array?

Did you get this working?

I saved your HTML on a test.php page, on its own, and it worked fine.

Output using print_r($_GET):

Array (
[main_page] => index
[Flt_Grade] => Array ( [0] => 100 )
[filter_id] => 4
)
