How to overload the constructor with new id

[Peter]

I have a table with an id called 'number' instead of the preferred
name 'id' used by the dbobject class.

How would I overload the constructor to use 'number' as the id column?

Hi

This is the constructor in class.dbobject.php

Drop this constructor in your class that is extending DBObject, and don't call parent::__construct

The best thing would to move "$this->idColumnName = 'id';" form the constructor to the definition of the object.

In that case one would only need to set $this->columnName before calling parent::__construct in the class extending DBObject.

protected function __construct($table_name, $columns, $id = null)

        {

            $this->className    = get_class($this);

            $this->tableName    = $table_name;

            // A note on hardcoding $this->idColumnName = 'id'...

            // In three years working with this framework, I've used

            // a different id name exactly once - so I've decided to

            // drop the option from the constructor. You can overload

            // the constructor yourself if you have the need.

            $this->idColumnName = 'id';

            foreach($columns as $col)

                $this->columns[$col] = null;

            if(!is_null($id))

                if (!$this->select($id))

                throw new Exception("Unknown ID");

        }
