SUBMIT A FORM WITH AJAX
09.11.2008 Posted by Marjan Trifunjagic in CakePHP No comments
The new release of CakePHP (RC2) comes with a completely rewritten AjaxHelper::form() function (with the disadvantage that it breaks existing code). Let’s look how to use it: <?php $ajax->form(array('action'=>'/controlle/action'),'post',array('update'=>'mydiv')); ?> I think this code is self-explanatory (if not, please write a comment). What’s cool about this code is the fact that it will also work when you disable JavaScript. The form will submit the form data in both cases to /controller/action. That means you have to distinguish in your action whether it is called via Ajax or not, and then you have at least to select the appropriate layout. You can do it in the following way (thanks to nate for this hint): <?php $headers = getallheaders(); if (isset($headers['x-requested-with'])) { $this->layout = 'ajax'; } You can access the form data in both cases as you are already used to with $this->params['data'] That’s it. It is really that simple :) Update (2006-03-16): The layout selection has changed (you still can use the approach described earlier), the new approach for doing the layout selection is: class YourController extends AppController { var $components = array('RequestHandler'); function youraction() { ... // do something $this->RequestHandler->setAjax($this); } }

HOW TO USE FIREBIRD WITH PHP?
09.11.2008 Posted by Marjan Trifunjagic in Firebird No comments
The simplest way of adding Firebird support is adding the interbase module to an existing PHP installation. On Windows it's a matter of simply unpacking the .zip package and extracting the PHP_INTERBASE.DLL extension, or choosing the Interbase package while installing from setup.exe installer. Please note that in the latter case, the installer also installs old gds32.dll from InterBase 6.0, which you need to delete manually and replace with Firebird's fbclient.dll (just rename it to gds32.dll). On Linux, you need to compile the interbase.so module. It is done like this: 1. install php-devel package (needed for phpize. If you already have phpize command, you don't need it) 2. get the php source code for the exact version as you are running 3. unpack the source and go to ext/interbase directory 4. run: phpize 5. run: ./configure --with-interbase=shared,/opt/firebird 6. run: make 7. this will create interbase.so module (most probably in .libs subdirectory) The following steps apply for Windows as well: 8. copy the module (.so or .dll) to /usr/lib/php/extensions (or whatever is the 'extension_dir' setting in php.ini) 9. uncomment the ;extension=php_interbase.dll in php.ini 10. restart Apache if you are using PHP with it Here's a set of tests to see if you extension is working properly: http://fbexport.sourceforge.net/ibtest.php.txt Please note that PHP5.x has a bug regarding NUMERIC(18,7) and other datatypes with precision higher than 6. The bug has been reported to PHP bug tracker, but is not fixed yet (PHP 5.2.3).
