[Deprecated] DMZ 1.5.3 (DataMapper OverZealous Edition)

That's because _input_dropdown is not a static method of the HTMLForm class.

Off the top of my head, I'm not sure what the best solution is. I guess for now, you'll need to instantiate a new HTMLForm class, and then call it on that instance. The overhead should be minimal, unless you need it more than (say) 10 times on one page.

Code:

function input_mydropdown($object, $field, $value, $options)
{
    array_unshift($options['list'], array( 0 => '-- Select --'));
    $hf = new HTMLForm();
    return $hf->_input_dropdown($object, $field, $value, $options);
}

Another option for you would be to "extend" HTMLForm as your own class, then use that extension. I'd try something like this:

Code:

include_once(APPPATH . 'datamapper/htmlform.php');
class myHTMLForm extends DMZ_HTMLForm // v1.5.0
{
    function _input_dropdown($object, $field, $value, $options)
    {
        array_unshift($options['list'], array( 0 => '-- Select --'));
        return parent::_input_dropdown($object, $field, $value, $options);
    }
}

Then just load in the extension 'myhtmlform', or whatever you choose call it.


I admit, I really haven't spent enough time making HTMLForm itself extensible. It takes a lot of work just writing the extensions in the first place. I also have to admit, I don't use the extension myself! :-) This is because I have a lot of legacy code I don't have time to refactor.

Let me know if one of these options works for you. In the future, I'll create a better way to extend HTMLForm, but I have other projects on my plate right now.
