Sep14Security component black hole, form submit dies on a blank page with no error
The problem started when i used Auth component in my current CakePHP project. Everything seemed working fine until i created an html form, submitted it and tried to retrieve this form’s data in controller action. I tried to print $this->data in controller action but it showed nothing and ended on a blank white page (which is called “blackHole” in Security component’s language). Click to continue »
Aug20Fix to jQuery plugin does not work on ajax loaded content
I had been loading table records through ajax pagination using jquery. Some of the urls/links (View Details, Edit and Delete) in loaded content had been using thickbox to handle respective requests. Although, if i did’t use the ajax to load records these links would work fine and thickbox would open. But once i introduced ajax they suddenly stopped working. Click to continue »
Jul01Cakephp pagination and custom named arguments handling
Let’s have a look at the scenario first.
I have a “contacts” controller, a “display” action in it(controller) and a view “display.ctp” to show results. As normal my “display” action lists all the contacts by calling $this->set(‘contacts’, $this->paginate(‘Contact’)) inside the controller action “display”. The view works normal. Click to continue »

If you plan your Cakephp application depend heavily on Javascript, its right time to chose jQuery for your cakephp-cum-javascript needs. Click to continue »
May07Simple captcha component for CakePHP (New)
Updated on – December 23, 2011
Follow these simple steps to make it working. (I assume that someone trying it has proficient knowledge of CakePHP framework. I may or may not help in problems which are related to knowledge of CakePHP rather than component itself).
Copy attached font file (monofont) to ‘webroot’ folder.
Copy component file (captcha.php) to app/controllers/components
Create a function similar to the following in your controller. (NOTE: I have used “signups” controller for demonstration purpose only. You should change controller name accordingly.)
function captcha() {
$this->autoRender = false;
$this->layout='ajax';
if(!isset($this->Captcha)) { //if Component was not loaded throug $components array()
App::import('Component','Captcha'); //load it
$this->Captcha = new CaptchaComponent(); //make instance
$this->Captcha->startup($this); //and do some manual calling
}
//$width = isset($_GET['width']) ? $_GET['width'] : '120';
//$height = isset($_GET['height']) ? $_GET['height'] : '40';
//$characters = isset($_GET['characters']) && $_GET['characters'] > 1 ? $_GET['characters'] : '6';
//$this->Captcha->create($width, $height, $characters); //options, default are 120, 40, 6.
$this->Captcha->create();
}
Call the captcha action from within your img tag in the view file as below:
echo $form->create("Signups");
echo $html->image($html->url(array('controller'=>'signups', 'action'=>'captcha'), true),array('style'=>'','vspace'=>2)); ?>
echo 'Enter the given security code:';
echo $form->input('Signup.captcha',array('autocomplete'=>'off','label'=>false,'class'=>'','error'=>__('Failed validating code',true)));
echo $form->submit(__(' Submit ',true));
echo $form->end();
And you are done! The captcha image should look like 
Also, you can re-generate the captcha by adding (replacing code in line 2 of the above) ajax code something similar to the following:
<div id="captchaID" ><?php
echo $html->image($html->url(array('controller'=>'signups', 'action'=>'captcha'), true),array('style'=>'','vspace'=>2)); ?></div>
<?php echo $ajax->link('Can not read this code? Reload.','regenerate code',array('url'=>'reload_captcha','update'=>'captchaID')); ?>
In the code above it calls a reload_captcha function of the current controller. You can place reload_captcha in current controller or preferrably in the app_controller to make it available universally. Here’s the code:
function reload_captcha() {
App::import('Component','Captcha'); //load it
$this->Captcha = new CaptchaComponent(); //make instance
$this->Captcha->startup($this); //and do some manually calling
$this->layout='ajax';
Configure::write('debug',0);
$this->viewPath = 'elements'.DS;
$this->render('reload_captcha');
}
Obviousaly it renders a reload_captcha element. So create a reload_captcha.ctp file and place it in views/elements with the following code in it:
<?php echo $html->image($html->url(array('controller'=>'signups', 'action'=>'captcha'), true),array('style'=>'','vspace'=>2)); ?>
There is model validation code included in the files with example of how to validate it. Files include a model with new validation entry along with two function.
You can see it in working here. Let me know if you discover any issue while implementing it. Your suggestions to improve it are always welcome.
