UknowvaTable

Object constructor to set table and key fields. In most cases this will be overridden by child classes to explicitly set the table and key fields for a particular database table.

Magic method to convert the object to a string gracefully.

Sets a default value if not alreay assigned

Returns a property of the object or the default value if the property is not set.

Returns an associative array of object properties.

Get the most recent error message.

Return all errors, if any.

Modifies a property of the object, creating it if it does not already exist.

Set the object properties based on a named array/hash.

Add an error message.

Get the columns from database table.

Static method to get an instance of a JTable class if it can be found in the table include paths. To add include paths for searching for JTable classes see JTable::addIncludePath().

Add a filesystem path where JTable should search for table class files.

You may either pass a string or an array of paths.

Method to get the database table name for the class.

Method to get the primary key field name for the table.

Method to get the JDatabase connector object.

Method to set the JDatabase connector object.

Method to set rules for the record.

Method to get the rules for the record.

Method to reset class properties to the defaults set in the class definition. It will ignore the primary key as well as any private class properties.

Overloaded bind function to pre-process the params.

Method to load a row from the database by primary key and bind the fields to the JTable instance properties.

Method to perform sanity checks on the JTable instance properties to ensure they are safe to store in the database. Child classes should override this method to make sure the data they are storing in the database is safe and as expected before storage.

Method to store a row in the database from the JTable instance properties.

If a primary key value is set the row with that primary key value will be updated with the instance property values. If no primary key value is set a new row will be inserted into the database with the properties from the JTable instance.

Method to provide a shortcut to binding, checking and storing a JTable instance to the database table. The method will check a row in once the data has been stored and if an ordering filter is present will attempt to reorder the table rows based on the filter. The ordering filter is an instance property name. The rows that will be reordered are those whose value matches the JTable instance for the property specified.

Method to delete a row from the database table by primary key value.

Method to check a row out if the necessary properties/fields exist. To prevent race conditions while editing rows in a database, a row can be checked out if the fields 'checkedout' and 'checkedout_time' are available.

While a row is checked out, any attempt to store the row by a user other than the one who checked the row out should be held until the row is checked in again.

Method to check a row in if the necessary properties/fields exist. Checking a row in will allow other users the ability to edit the row.

Method to increment the hits for a row if the necessary property/field exists.

Method to determine if a row is checked out and therefore uneditable by a user. If the row is checked out by the same user, then it is considered not checked out -- as the user can still edit it.

Method to get the next ordering value for a group of rows defined by an SQL WHERE clause.

This is useful for placing a new item last in a group of items in the table.

Method to compact the ordering values of rows in a group of rows defined by an SQL WHERE clause.

Method to move a row in the ordering sequence of a group of rows defined by an SQL WHERE clause.

Negative numbers move the row up in the sequence and positive numbers move it down.

Method to set the publishing state for a row or list of rows in the database table. The method respects checked out rows by other users and will attempt to checkin rows that it can after adjustments are made.

Generic check for whether dependancies exist for this object in the database schema

Can be overloaded/supplemented by the child class

Method to export the JTable instance properties to an XML string.
