I'm facing a strange problem. I'm trying to define a custom field for the frontend-view of my component like this:

defined('JPATH_BASE') or die;


class JFormFieldAssignToUser extends JFormFieldList
    protected $type = 'assigntouser';

    protected function getInput() 
        $html                 =     array();
        $user                 =     JFactory::getUser();

        $html[]             =     JHtml::_('select.option', 

        $html                 =     array_merge(parent::getOptions(), $html);

        return $html;

now I'm adding this to my xml:

<field    name            =        "assigntouser" 
        type            =        "assigntouser"    
        label            =        "TEST"                
        description        =        "TEST"
        filter            =        "safehtml"
        default            =        "">
            <option value    =    "">TEST</option>

and include it to my layout like that:

<?php echo $this->form->renderFieldset("testfieldset"); ?>

But it only shows this error:

Notice: Array to string conversion in /var/www/web1/htdocs/layouts/joomla/form/renderfield.php on line 35

A field, which is designed in the same way, that is added to the backend of Joomla, works without problems...


I think you want to use use getOptions(..) not getInput(...) with a JFormFieldList.

getInput returns the full <select /> input as a string. getOptions populates the select options with an array of <option /> strings.
