Question

I am using codeigniter for my project and couldn’t find what’s wrong with my code. This is my controller code

$products = $this->products_model->getProductsQuantity($id);
$q = $warehouse_product->quantity;

object notation is working but getting error: Trying to get property of non-object

$q = $warehouse_product['quantity'];

array notation not working and getting php error: Fatal error: Cannot use object of type stdClass as array in products\controllers\products.php on line xx

Here is my model function

public function getProductsQuantity($product_id) 
    {
        $q = $this->db->get_where('products', array('product_id' => $product_id), 1); 
          if( $q->num_rows() > 0 )
          {
            return $q->row();
          } 

          return FALSE;

}

Please help me to fins where is the problem in my code.

Answer 1

You should look at this

if you are limiting your results to 1 as in your get_where instruction then return

$q->row_array() // for array

And

$q->result_array() // for object

And in Controller do this

$products = $this->products_model->getProductsQuantity($id);
$quantity = $products->quantity; // Object notation

And

$quantity = $products['quantity']; // Array notation
