you're treating $ingredient_id string it's array. name variables type i'm expecting don't confused... example, $ingredient_id_array.
// var_dump($savedata); die(); $ingredient_id_array = $this->products_model->saveingredients($savedata); foreach (explode(',', $this->input->post('ingredient_category')) $key => $value) { foreach ( $ingredient_id_array $key => $str ){ $joindata[] = array( 'ingredient_id' => intval( $str ), 'category_id' => intval( trim($value) ) ); } }
