Separate key=>value combobox
The original jQuery combobox allows for separate key=>value pairs. In order to add this functionality to the combobox I added a public property $assoc and the run() method has to be changed as follows:
public function run()
{
list($name, $id) = $this->resolveNameID();
if (is_array($this->data) && !empty($this->data)){
//if $data is not an assoc array make each value its key
if($this->assoc){
$data=$this->data;
}
else{
$data=array_combine($this->data, $this->data);
}
//does the same as array_unshift($data,null) but does not break assoc arrays
$data=array(""=>"")+$data;
}
else
$data = array();
if ($this->hasModel())
echo CHtml::activeDropDownList($this->model,$this->attribute,$data);
else
echo CHtml::dropDownList($name, $this->value, $data);
echo CHtml::textField(null,
($this->hasModel()?
$data[CHtml::resolveValue($this->model,$this->attribute)]:
$data[$this->value]
),array('id'=>$id.'_combobox')
);
$this->options = array_merge($this->defaultOptions, $this->options);
$options = CJavaScript::encode($this->options);
$cs = Yii::app()->getClientScript();
$js = "combobox({$options});";
list($id, $js) = $this->setSelector($id.'_combobox', $js);
$cs->registerScript(__CLASS__ . '#' . $id, $js);
}
Full code on GitHub
IMPORTANT the combobox input field has "_combobox" appended to its id. The select now has the original name and id of the field.
Shout out to @_construct() for the bug fix.
An example of the usage is below
$this->widget('ext.combobox.EJuiComboBox', array(
'model' => $myModel,
'attribute' => 'myAttribute',
// data to populate the select. Must be an array.
'data' => array('Y'=>'Yii','R'=>'Rocks')
'assoc'=>true,
....
));
