Creating validation for a checkbox array.

[eluser]Bramme[/eluser]
okay, I'm implementing that tonight :p

Can't access the svn folder from my work atm... Stupid proxy.

Did they include something to prepolute the checkboxes? Because my hacks are rather ugly at the moment. It seems to be working though.

This is smth from my controller:

Code:

if( $this->input->post('categories') != FALSE) {
    $data['checkbox_array'] = $this->input->post('categories');
} else {
    $this->db->where('tutID', $tutID);
    $tutcats_query = $this->db->get('tutorial_categories');
    foreach($tutcats_query->result() as $row) {
        $selected_cats[] = $row->catID;
    }
    $data['checkbox_array'] = $selected_cats;
}

in my view i've got

Code:

<input type="checkbox" name="categories[]" value="<?=$cat['catID']?>" id="cat-<?=$cat['catID']?>" <?php echo $this->validation->set_checkbox_array($cat['catID'], $checkbox_array); ?>/>

And in MY_Validation.php

Code:

function set_checkbox_array($needle = '', $haystack = array())
{
    if(empty($needle) OR empty($haystack))
    {
        return FAlSE;
    }
    else if (in_array($needle, $haystack))
    {
        return 'checked="checked"';
    }
    else
    {
        return FAlSE;
    }
}
