Using a for loop with an array?

[Iain M]

Hi,

I'm having problems validating radio options from a form, before entering into the database.
Because the names of the radio options change depending on the row id.
I put my validation into a for loop, but it didn't work - nothing was posted from the form.

PHP Code:

        for($i=$oldestID['id'];$i<=$newestID['id'];$i++)
        {
            // Clean parameters
            $vbulletin->input->clean_array_gpc('p', array(
                'gender_$i'    => TYPE_BOOL,
                'free_$i'    => TYPE_BOOL,
                'active_$i'    => TYPE_BOOL,
            ));  
            // Easy names
            $gender = $vbulletin->GPC['gender_$i'];
            $free = $vbulletin->GPC['free_$i'];
            $active = $vbulletin->GPC['active_$i'];        

            // Do stuff
        } 


The names of the fields are:
gender_{vb:raw id}
free_{vb:raw id}
active_{vb:raw id}

id changes for each row pulled from the database, so we'll have

HEADER
Row 1: gender_1 | free_1 | active_1
Row 2: gender_2 | free_2 | active_2
Row 10: gender_10 | free_10 | active_10

Could someone point me in the right direction?

If I use

PHP Code:

            $gender = $_POST["gender_$i"];
            $free = $_POST["free_$i"];
            $active = $_POST["active_$i"]; 


in my for loop, it works fine, but I'd rather validate the entries.



Thanks in advance for your help.
