Database Abstraction Layer

A.6.1.1 Description

DB is a database abstraction layer providing:

• an OO-style query API

• portability features that make programs written

  • for one DBMS work with other DBMS's

• a DSN (data source name) format for specifying

  • database servers

• prepare/execute (bind) emulation for databases

  • that don't support it natively

• a result object for each query response

• portable error codes

• sequence emulation

• sequential and non-sequential row fetching as

  • well as bulk fetching

• formats fetched rows as associative arrays,

  • ordered arrays or objects

• row limit support

• transactions support

• table information interface

• DocBook and PHPDoc API documentation

DB layers itself on top of PHP's existing database extensions. The currently supported extensions are: dbase, fbsql, interbase, informix, msql, mssql, mysql, mysqli, oci8, odbc, pgsql, sqlite and sybase.

DB is compatible with both PHP 4 and PHP 5.

A.6.7. DB_DataObject_FormBuilder

Repository: PEAR - License: PHP License - By Markus Wolff (lead)

Class to automatically build HTML_QuickForm objects from a DB_DataObject-derived class

A.6.7.1 Description

DB_DataObject_FormBuilder will aid you in rapid application development using the packages DB_DataObject and HTML_QuickForm. For having a quick but working prototype of your application, simply model the database, run DataObject´s createTable script over it and write a script that passes one of the resulting objects to the FormBuilder class. The FormBuilder will automatically generate a simple but working HTML_QuickForm object that you can use to test your application. It also provides a processing method that will automatically detect if an insert() or update() command has to be executed after the form has been submitted. If you have set up DataObject´s links.ini file correctly, it will also automatically detect if a table field is a foreign key and will populate a selectbox with the linked table´s entries. There are many optional parameters that you can place in your DataObjects.ini or in the properties of your derived classes, that you can use to fine-tune the form-generation, gradually turning the prototypes into fully-featured forms, and you can take control at any stage of the process.
