Big problem with arrays and checkboxes - El Forum - 10-11-2007

[eluser]Référencement Google[/eluser]
Hi,

I am facing a big problem to repopulate checkboxes group from a DB.
Here are the situations:

- The checkbox group can be empty the first time, because we have to add the user selection to the DB
- The checkboxes can be selected according to the DB, for exemple in a editing case
- Finally, we have to keep the choice of the user while posting the form for validation.

So here is my actual code:

Code:
function DB_checkBoxes($data, $fieldName, $values = array())

{

    $CI =& get_instance();

    $html = '';

    $selected = '';

    foreach($data as $item)

    {

        if (!empty($_POST))

        {

           $selected = $CI->validation->set_checkbox($fieldName, $item->word_ID);

        }

        foreach ($values as $value)

        {

            if ($value->word_ID === $item->word_ID)

            {

               $selected = ' checked="checked"';                  

            }

        }

        $html .= "    <label class=\"checkbox\">";

        $html .= "&lt;input type=\"checkbox\" name=\"".$fieldName."[]\" value=\"".$item-&gt;word_ID."\"".$selected." /> ".$item->word;

        $html .= "</label>\n";            

    }

    return $html;

}

Code explaination:
$data is an array containing all the checkboxes
$fieldName is the name of the input, in my casse it will be for exemple choices[]
$values is the array coming from the DB with the checked checkboxes that was saved by the user

I don't know if somebody can help me, really I tryed almost all day about that and can't find the solution!
