My Model

public function CheckProductInsert($company_id,$purchase_or_id,$product_id,$supplier_id){
    $company_id = $this->db->escape_str($company_id);
    $purchase_or_id = $this->db->escape_str($purchase_or_id);
    $product_id = $this->db->escape_str($product_id);
    $supplier_id = $this->db->escape_str($supplier_id);
    $k="SELECT id 
            FROM gacc_purchases_or_details 
            WHERE 
                purchase_or_id=$purchase_or_id 
                AND product_id=$product_id
                AND supplier_id=$supplier_id
                AND company_id=$company_id
                AND activate=1";
    $re = $this->db->query($k);
    if($re->num_rows() > 0){
        return true;
    }else{
        return false;
    }
}

My Controller

Answer 1

If you used Stored Procedure earlier in this code then this may be the solution

For reference - link

solution :

add following code into /system/database/drivers/mysqli/mysqli_result.php

 function next_result()
 {
     if (is_object($this->conn_id))
     {
         return mysqli_next_result($this->conn_id);
     }
 }

then in model when you call Stored Procedure

$query    = $this->db->query("CALL test()");
$res      = $query->result();

//add this two line 
$query->next_result(); 
$query->free_result(); 
//end of new code

return $res;

or else if you dont want to edit the system files then try this in model when you call Stored Procedure

mysqli_next_result( $this->db->conn_id );
$query->free_result();
