The function public function add( $type, $value ){ $this->values[] = $value; $this->types .= $type; } Should be public function add( $type, &$value ){ $this->values[] = $value; $this->types .= $type; } Otherwise, this : call_user_func_array( array($stm, 'bind_param'), $bindParam->get()); Will return this : Warning: Parameter 2 to mysqli_stmt::bind_param() expected to be a reference, value given Test script: --------------- // class BindParam copied from user comment $bindParam = new BindParam(); $qArray = array(); $column1NewValue = $_POST['column1']; $column2NewValue = $_POST['column1']; $qArray[] = 'Column1 = ?'; $bindParam->add('i', $column1NewValue ); $qArray[] = 'Column2 = ?'; $bindParam->add('s', $column2NewValue ); $query = 'UPDATE myTable SET '; $query.= implode(' , ', $qArray); $query.= ' WHERE PKeyID= ?'; $bindParam->add('i', $lineToUpdate); $stmt = $mysqli->prepare($query); call_user_func_array(array($stmt, 'bind_param'), $bindParam->get()); $stmt->execute(); $stmt->close(); Expected result: ---------------- Row in database properly updated.
