I am trying to use a select box to update another select box using ajax. I have two tables: locations and nodes, and Locations hasMany Nodes and Nodes belongsTo Locations. I want a locations select box to update the nodes select box with all the nodes that are at that location. I've been to multiple forums with great tutorials explaining how this works, but I follow their directions exactly and it never works. I am brand new to any type of AJAX development, and I have only been developing with CakePHP for a couple weeks now.
Here is the code: In my controller: ---------------------------------------------------------------------------------------------------------------------------- function update_select() { if(!empty($this->data)) { $locationId = $this->data['Location']['id']; $options = $this->Iface->Node->find('list', array('conditions'=>array ('Node.location_id'=>$locationId))); $this->set('options', $options); $this->render('update_select'); } } ---------------------------------------------------------------------------------------------------------------------------- In my view: ---------------------------------------------------------------------------------------------------------------------------- <?php echo $form->input('Location.id', array ('type'=>'select','options'=>$locations, 'id' => 'LocationId', 'label'=>'Location')); ?> <?php echo $form->input('Node.id', array('type'=>'select', 'options'=> $nodes,'id' => 'NodeId', 'label'=>'Node')); ?> ---------------------------------------------------------------------------------------------------------------------------- In my update_select.ctp: ---------------------------------------------------------------------------------------------------------------------------- <?php foreach ($options as $i => $option): ?> <option value="<?php echo $i; ?>"><?php echo $option; ?></option> <?php endforeach; ?> ---------------------------------------------------------------------------------------------------------------------------- (I have Ajax and Javascript helpers, RequestHandler component, and prototype all defined) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CakePHP" group.
