Sorry It was My Mistake using dual jQuery different versions 

 

I have an issue i have created an extra hidden field in the form in which i put the receipt values items as json after Save click i receive those in insert into the other table and unset(post_array['jdata']) and return the post array but after this i get the view which is in the attachments:[attachment=1044:error.png]

i don't know how to resolve it and my code is bellow 

	public function index()
	{
		$crud = new grocery_CRUD();

			//$crud->set_theme('metro_blue');

			$Ol=$this->session->userdata('outlet_id');
			$crud->where('fee_payments.outlet_id',intval($Ol));

			$crud->set_table('fee_payments');

			$crud->field_type('outlet_id', 'hidden', '$Ol');
			$crud->unset_columns('outlet_id');
			$crud->fields('jdata','student_id','Recipt','total_amount','total_discount','paid_amount','date','of_month','outlet_id');
			$crud->field_type('outlet_id', 'hidden', $Ol);
			$crud->callback_add_field('Recipt',array($this,'add_field_callback_1'));
			
			$crud->field_type('jdata', 'hidden','abc' );
			$crud->callback_before_insert(array($this,'insertRecipt_callback'));
			$output = $crud->render();
			$output->title="Fee";
			$output->menuActive="Fee";
			$this->_example_output($output);
	}
	public function insertRecipt_callback($post_array){
		$obj1=json_decode($post_array['jdata']);
		foreach($obj1 as $key=>$value){
			$value->discount=$value->percent_discount;
			unset($value->percent_discount);
			unset($value->student_id);
			unset($value->code);
			unset($value->paid_amount);
		}
		$this->admin_model->batch_insert("fee_recipts",$obj1);
		unset($post_array['jdata']);
		 return $post_array;
	}

i create the jdata by using ajax
