Problem with checkboxes

[eluser]Johan André[/eluser]
I searched the forums alot for a solution to the problem that checkboxes don't get set correctly when using

Code:

set_checkbox()

I found no solution so I created one myself.

Maybe I'm a complete idiot and not able to read the userguide correctly... Anyway, here it is:

1. Create a file named "MY_form_helper.php" in application/helpers. This will extend (actually overload/append) new functions to the form_helper.php supplied in system/helpers/.

2. Add the following code to the file:

Code:

<?php
function checkbox_check($field, $val)
{
    if(isset($_POST[$field]))
    {
        if($_POST[$field] == 1)
        {
            return ' checked="checked"';
        }    
        return '';
    }
    if($val == 1)
    {
        return ' checked="checked"';
    }
    return '';
}

3. Use like this in your view (assumes you have data in $item['my_checkbox']. 1 = checked, 0 = not checked):

Code:

<label for="my_checkbox">Check it</label>
&lt;input type="checkbox" name="my_checkbox" &lt;?php echo checkbox_check('my_checkbox', $item['my_checkbox']); ?&gt; value="1" /&gt;
&lt;?php echo form_error('my_checkbox'); ?&gt;
</div>

The function will check the $_POST-array is the actual key exist. If it does it will use it. If it does'nt the default data (from database or whatever) will be used.

Hope this helps someone...
