8.8 Summary
PHP may be used with Ajax either by directly specifying a PHP script
URL in the open() method of the XMLHttpRequest object or with a
PHP framework for Ajax. JDeveloper 10g provides an extension for PHP
for running PHP files in JDeveloper. Xajax is a PHP Ajax framework. In
this chapter we is configured the PHP extension for JDeveloper in
JDeveloper 10g. Using Xajax we sent an Ajax request from an input form
to create a catalog entry. Ajax is used to validate a catalog id for creating a
new catalog entry. Using the Ajax response a validation message is
displayed to indicate the validity of a catalog id.
