การส่งแบบ POST

$(function(){
     $("#save_type").click(function(){	
		              path = '/it_wallet/category/updatetype?id='+$('#type_id').val();
				
				$.ajax({
					url: path,
					type:'POST',
					dataType:'json',
					data:{name:$('#type_title').val(),description:$('#type_description').val()},
  	   	           success: function (data) {
					 
  	   				}
				});
				
			});});

PHP

  public function actionUpdate($id)
    {  	       $extraData = Yii::$app->request->post();
		$model = Category::findOne($id);
 	        $model->name = $extraData['name'];
	        $model->type_id= $extraData['type_id'];
	 	$model->image_path= $extraData['image_path'];
 	        $model->description = $extraData['description'];
                $model->save();
          echo json_encode(array("id"=>$model->id,'type_id'=>$model->type_id,"name"=>$model->name,"description"=>$model->description,"image_path"=>$model->image_path),JSON_PRETTY_PRINT);
    }
   

การส่งแบบ GET

 $.ajax({
				url: '/it_wallet/category/show_content',
				type:'GET',
				dataType:'json',
   	                        success: function (data) {
				  //   alert("show content");
				  //   alert(data.title);
				  info_data = data.all;
   				}
			});

PHP

  public function actionShow_content()
    { 
		$request = Yii::$app->request->post();
                $types = Type::find()->all();
		$type_array = [];
		
		foreach($types as $type){
			$categories_array = [];
			foreach($type->getCategories()->orderBy("sequence ASC")->all() as $cat){
				$categories = ["id"=>$cat->id,"type_id"=>$cat->type_id,"name"=>$cat->name,"description"=>$cat->description,"image_path"=>$cat->image_path];
				array_push($categories_array,$categories);
			}
			$type_each = ["id"=>$type->id,"name"=>$type->name,"description"=>$type->description,"categories"=> $categories_array];
			
			array_push($type_array,$type_each); 
		}
               echo json_encode(array("all"=>$type_array),JSON_PRETTY_PRINT);
    }

การส่ง Association Array ผ่าน Ajax  ใน jquery

 function UpAndDown(obj){
		
      var row = $(obj).parents(".tab-category:first");
	  alert($(row).attr('id'));
        if ($(obj).is(".up")) {
            row.insertBefore(row.prev());
        } else {
            row.insertAfter(row.next());
        }
		var all_row = $(obj).parents("li:first").find('.tab-category');
		var order_array = [];
		for(vi =0;vi<all_row.length;vi++ ){
			var order=new Object();
			id= $(all_row[vi]).attr('id');
			hid = id.toString().substr(4);
			order.sequence=vi;
			order.id=hid;	
			order_array.push(order);
			
		}
		
		
		//update sequence 
		$.ajax({
			url: '/it_wallet/category/update_sequence',
			type:'POST',
			dataType:'json',
			data:{order:JSON.stringify(order_array)},
			success: function (data) {
				//alert(data.status);
			
			}
	
		});
   }

PHP

   public function actionUpdate_sequence()
    {  	$request = Yii::$app->request->post();
		
 	$orders = json_decode($request['order'],true);
	 foreach($orders as $order){
		
	   $model = Category::findOne($order['id']);
			$model->sequence =  $order['sequence'];
			$model->save();
	    }
          echo json_encode(array('status'=>$request['order']),JSON_PRETTY_PRINT);
    }
