How to use joomla JHTML::_('select.genericlist') with selected option

[Fejér Ferenc]

I try for a while to understand how can I add selected option to my dropdownlist my code looks as it follows. I create an option array than I genrate the list, on the next step I check if already has the a filed a selected option if yes I would like show as <option value = "my_value" selected="my_selected">My selected</option>


The code above won't do that

    public function getInput() {
       
        $spec_fields = array();
       
        $jinput = JFactory::getApplication()->input;
        $id = $jinput->get('id');

        $db = JFactory::getDbo();
        $query = $db->getQuery(true)
                ->select('*')
                ->from('#__immobilien_cat')
                ->order('cat_name');
        $db->setQuery($query);
        $rows = $db->loadObjectList();

        if (isset($id)) {
    
        $query = $db->getQuery(true)
                ->select('cat.id,cat.cat_name')
                ->from('#__imobillien AS immo')
                ->join('LEFT', '#__immobilien_cat AS cat ON immo.category_id = cat.id')
                ->where('immo.id = ' . $id);
        $db->setQuery($query);
        $actual_row = $db->loadRow();
        var_dump($actual_row[1]);
        }
       
        $options[] = JHTML::_('select.option','',JText::_('COM_IMMOS_SELECT_CAT'));
        foreach ($rows as $key => $value) {
            $options[] = JHTML::_('select.option', $value->id, JText::_($value->cat_name));    
        }

        //return JHTML::_('select.genericlist', $options,'jform[category]', 'class="nourritures"','value','text',$actual_row[1]);
        return JHTML::_('select.genericlist', $options, 'jform[category]', 'class = "nourritures"', 'value','text', 'Villa' );
             

    }

mixed $selected: The key that is selected (accepts an array or a string).

You don't need the foreach to iterate over the $rows. Just pass the objectlist as a parameter to JHtmlSelect and it will do the magic.

You then specify which properties of the object should be used as value and text, text will also be translated by default.

The $selected has to contain the id of the selected value. JHtml will then assign it itself.

JHtml::_('select.genericlist', $rows, 'jform[category]', 'class = "nourritures"', 'id','cat_name', $row->id);
