What is does

This extension provides the xAjax PHP Class Library Version 0.2.4. It is used by other TYPO3 extensions like tt_products.


In your extension.

TYPO3 11 and later

You must set this TypoScript to get the absolute image path:

config.absRefPrefix = /

Otherwise an image url “fileadmin/myimage.png” will not be found, because HTML will generate a path like “https://example.com/subpage1/subpage2/fileadmin/myimage.png” out of it.

TYPO3 9.5 and later:

Add the following line into the file ext_localconf.php of your extension my_ext.

$GLOBALS['TYPO3_CONF_VARS']['FE']['taxajax_include']['my_ext'] =  \MyDomain\MyExt\Controller\TaxajaxController::class . '::processRequest';

The links generated by typolink must contain this element inside of the querystring:

$addQueryString = [
    'taxajax' => 'my_ext'

TYPO3 < 9.5:

For TYPO3 < 9.5 use the eID parameter instead of taxajax

$GLOBALS['TYPO3_CONF_VARS']['FE']['eID_include']['my_ext'] =  \MyDomain\MyExt\Controller\TaxajaxController::class . '::processRequest';

The links generated by typolink must contain this element inside of the querystring:

$addQueryString = [
    'eID' => 'my_ext'

xajax PHP Class Library

The easiest way to develop asynchronous Ajax applications with PHP

Version 0.2.4 (stable release) Release Notes:
  1. Introduction

xajax is a PHP library that you can include in your PHP scripts to provide an easy way for Web pages to call PHP functions or object methods using Ajax (Asynchronous Javascript And XML). Simply register one or more functions/methods with the xajax object that return a proper XML response using the supplied response class, add a statement in your HTML header to print the Javascript include, and run a request processor prior to outputting any HTML. Then add some simple Javascript function calls to your HTML, and xajax takes care of the rest!

xajax includes a Javascript object to facilitate the communication between the browser and the server, and it can also be used as a Javascript library directly to simplify certain DOM and event manipulations. However, you can definitely choose to use a dedicated Javascript “engine” of your liking and integrate it with xajax’s client/server communication features in a number of ways. More tightly-coupled integration will be forthcoming in a future version of xajax.

The official xajax Web site is located at: http://www.xajax-project.org

Visit the xajax Forums at: http://community.xajax-project.org to keep track of the latest news and participate in the community discussion.

  1. Installation

To run xajax, you need: * Apache Web Server or IIS for Windows XP/2003 Server (other servers may or may not work and are not supported at this time) * PHP 5.5 and later

To install xajax: Unpack the contents of this archive and copy them to your main Web site folder. Or if you wish, you can put all of the files in a dedicated “xajax” folder on your Web server (make sure that you know what that URL is relative your site pages so you can provide xajax with the correct installed folder URL). Note that the

“thewall” folder in the “examples” folder needs to be writable by the Web server for that example to function.

  1. Documentation

Detailed documentation for the xajax PHP classes is available on our wiki (URL listed above in section 2), and more is on the way (particularly in regards to the Javascript component of xajax). Another good way of learning xajax is to look at the code for the examples and tests. If you need any help, pop in the forums and ask for assistance (and the more specific your questions are, the better the answers will be).

  1. Contributing to xajax

xajax is released under the LGPL open source license. If you wish to contribute to the project or suggest new features, introduce yourself on the forums or you can e-mail the lead developers at the addresses listed at the top of this README.
