Making jquery ajax call from view to controller in cakephp 2.x

Question

I Am trying to make an ajax request from the view to controller, ajax requst is working fine, but from controller nothing is returned back to the view. i don't know where is the problem.. what i am trying is in my view side i am displaying some data from the controller and there is one select box. whe i select a city from the select box, it calls the ajax request and should show the result from that particular city in the view.ctp.

 $('#cityid').change(function() { $city_id= $('#cityid :selected').val(); alert($city_id); $.ajax({ url : "<?php echo Router::url(array('controller' => 'deals', 'action' =>'topdeals'), true); ?>", type : "POST", cache : false, data : {city_id: city_id}, success : function(data){ alert(data); } }); }); });

and in the view

 <div id="form"> <?php echo $this->Form->create('Deal', array('action'=>'topdeals','type'=>'post'));?> <?php echo $this->Form->input('city_id', array('label'=>'City','type'=>'select', 'id'=>'city_id','empty'=>'select City','options' =>$city)); echo $this->Form->end(); ?> </div> <div class="line"></div> <?php if(!empty($topdealsortbyrank)) { foreach($topdealsortbyrank as $topdealsortbyrank) {?> <div class="items"> <div class="itemslogo" > <?php echo $this->Html->image('deal/dealimage/'.$topdealsortbyrank['Deal']['image'],array('width'=>"100px",'height'=>"80px"));?> </div><!-- items Logo ends--> <div class="itemdetails"> <b><?php echo $topdealsortbyrank['Advertiser']['name']?></b> <p class="red"><?php echo $topdealsortbyrank['Deal']['title']?></p> <?php } }?>

And in the controller

 function topdealajax() { $this->log('Ajax call -----------------'); if ($this->request->isAjax()) { $this->log('inside if request is ajax -----------------'); $this->layout = null; $this->view = 'topdeals'; if(!empty($this->request->data)) { $this->log('inside if not empty of params -----------------'); $data = $this->request->data['city_id']; $this->log($data); $city_id=$data['city_id']; $this->log($city_id); $city_id= $this->request->data['city_id']; // $this->log($city_id); $topDealSortbyRank1=$this->Deal->find('all', array('conditions'=>array('date_expiry >=' =>date('Y-m-d ') , 'date_expiry <=' => 'date_expiry','Deal.city_id'=>$city_id),'order'=>array('Deal.deal_rank ASC'))); //$this->log($topDealSortbyRank1); $this->set('topdealsortbyrank',$topDealSortbyRank1); $this->render('topdeals'); } } }

you shouldn't use exit, or break, you have to let it render and return the response, otherwise it doesn't return anything — amstegraf

same for $this->autoRender = false. If nothing gets redered, nothing gets returned! just $this->layout = null, and then normal data manipulation and rendering — amstegraf

* first of all your action in the controller is topdealajax() and you make an ajax request for topdeals() * second of all in the controller you set $data as $this->request->['city_id'] instead of $this->request->['Deal']['city_id'] Am I wrong? Why don't you sent the form normally and var_dump the POST in the action to see you are getting the desired values for the variables — amstegraf

/*IN THE AJAX REQUEST YOU SHOULD HAVE*/ $.ajax({ ..... success: function(data){ $('#MYDIV').html(data);}, //YOU CAN APPEND OR REPLACE THE CONTENT OF A CONTAINER WITH THE RESPONSE ... }); //in DealsController::topdeals() you should have at the begining if ($this->request->isAjax()): $this->layout = null; $this->view = 'view_ajax'; //Other view that doesn't needs layout, only if necessary endif; /*DO WHATEVER YOU WANT HERE, SEND IT TO THE VIEW, THE VIEW GETS RENDERD AND RETURN AS A RESULT*/

ii tried but still not getting..the result is not send back to the view , that is the problem. ajax request is working fine and in controller i am getting the id..

$this->view = 'view_ajax'; //means that you can have a different template for the ajax return if you look at the comments I made above at your question you will see that you have a rendering issue, because you break with exit and set autoRender to false, which means nothing gets returned

before you try to get the answer by AJAX you should first access the controller manually and dump some data, to see what happens
