parentdbtoclass 1.1Freeware4.3Databases, Design Patterns
Description Author

This package uses the Active Record design pattern to map database table records to objects.

It provides a base class from which all classes that map database tables should inherit.

The sub-class should define the table it is wrapping, the primary key field and variables to store the table field values.

The base class can query the database to retrieve the list of fields of the specified table. It can also perform all the basic operations of INSERT, SELECT, UPDATE and DELETE the mapped table rows.

This package uses ADODb database abstraction package so it can support multiple databases.

coredb.class.php      - DB OBJECT HANDLER (REQUIRE ADODB) (include dirname(__FILE__)."/adodb/adodb.inc.php";)
j-coredb.class.php    - JOOMLA CMS DB OBJECT HANDLER WRAPPER 
parent.dbtoclass.php  - Database Table handler
sample.php	      - Sample handler of table 'catalog';



-------------------------------------------------------------------
Handler Usage >>> 
-------------------------------------------------------------------
For example we have mysql table 'catalog', with fields 'id','title','price':
What we do is :
1)Create Child class of parent.dbtoclass.php (class Foo extends dbtoclass ...) see sample.php
2)Make same fields in class as in db i.e.: see sample.php
3)you can call parent:::makeGetSetMethods() to get All get*,set* methods for all your class fields (title,price...)
4)Also you may get the list of changed values from parent class (value/field that waws realy cchanged, for logging)

/* Update existing  >>> */

$foo = new Foo($db); 	       	     #Initialize object with DB object
$foo->checkout(25);           	     #load item details to class
$foo->setNewValues($hash_array);    #update class with new values
$foo->commit();               	     #Commit all changes to db and write log
$foo->finish();               	     #Finish work with the class.

/* <<< */

/* Create new  >>> */

$foo = new Foo($db); #Initialize object with DB object
$foo->create($hash_array);               #Commit all changes to db and write log
$foo->finish();               #Finish work with the class.

/* <<< */

/* Delete record */

$foo = new Foo($db); #Initialize object with DB object
$foo->delete(25);			   #Delete item
$foo->finish();               #Finish work with the class.
