requestAction function calls a controller’s action from any location and returns data from the action. See below :

$clientdata=$this->requestAction('/clients/get_client_data/'.$clientid);

Above is code by which you can call controller method/action/function get_client_data from any location or view files. If you use above code it means you are calling client controller and calling get_client_data of client controller. Also you can see that I have passed $clientid with URL, $clientid is dynamic client id which we can passed automatically inside for loop to get client data evertime for loop runs.

When this function calls in view it execute get_client_data function and then return result from get_client_data function in $clientdata variable. In this way we can call controller function from any location or from view.

If you want to disable or not render or want to write controller function without view file then below is the one line code by which you can disable view by writing it in function :

$this->autoRender = false;

Just write this line where you want to disable view.

Below are the syntax to make link on image.

echo $html->link($html->image("user_red_delete.png"), 'javascript:;', array('escape' => false));

In above statement you just have to replace your image path with RED words “user_red_delete.png”.

After doing this you will see that your image will have link on itself.

So if you want to take current URL in cakePHP view than check out below code :

echo Router::url($this->here, true);

This will output current URL. If you want relative path and not full URL than you can do like this :

echo $this->here;

By this you can get relative path in the view.

Open app/config/core.php file and try to find

Configure::write('Cache.disable', true);

If this code is commented in core.php file that means your cache system is enabled in your site So if you want to disable just remove comments from this code, It will disable site wide cache.

If you want to use any other layout in view than you have to write in controller like this :

$this->layout = 'layout_name';

‘layout_name’ should be your layout name and which exists in ‘/app/views/layouts’ directory, Now if you dont want to include any layout in view than you have to make false layout for that controller. Like this.

$this->layout = false;

I am always using loadModel function to load model in controller but I am giving overview of both ways.

First I am explaining $uses variable method. Whenever you want to include or make available other model in controller than you can use $uses variable at start of controller like this
<?php
class RecipesController extends AppController {
var $name = 'Recipes';
var $uses = array('Product', 'User');
}
?>

As you see in above code by $uses variable I have included or make available two models Product and User, So If you want to make available other model in controller you can use $uses variable and than write your model name in that array.

Second way loadModel function, It is efficient way to make available model or load model in controller. Syntax of loadModel function :
$this->loadModel('User');
$users= $this->User->find('all');

In this way you can load model, Just pass model name in loadModel function and than you can use that model for Db interaction.

You can take advantage of CakePHP view/element caching if you supply a cache parameter. If set to true, it will cache for 1 day. Otherwise, you can set alternative expiration times. See Caching for more information on setting expiration.
<?php echo $this->element('helpbox', array('cache' => true)); ?>

Your default caching must be enabled for element caching to be worked.

If you render the same element more than once in a view and have caching enabled be sure to set the ‘key’ parameter to a different name each time. This will prevent each succesive call from overwriting the previous element() call’s cached result. E.g.
<?php
echo $this->element('helpbox', array('cache' => array('key' => 'first_use', 'time' => '+1 day'), 'var' => $var));

echo $this->element('helpbox', array('cache' => array('key' => 'second_use', 'time' => '+1 day'), 'var' => $differentVar));
?>
The above will ensure that both element results are cached separately.

So to make an element simple make a blank php file then write your element code in it and save that file in your app/views/element folder and save it as .ctp file, for this article we save it as top.ctp. Now in top.ctp you can write code you want to use/repeat in other/all pages. In top.ctp you can put html code for navigation menu or footer links or any other code which you want to use/repeat in pages.

Now below is the syntax by which you can include or call element:

<?php echo $this->element('top', array("variable_name" => "current")); ?>

Here you have to write only ‘top’ as element name, not top.ctp and you can pass one variable to that element(top.ctp) file as shown above. In above example after top there is one array by which we can pass a variable to that element file.If you want to see in detail that how to use passed variables in element then check out here.

<?php echo $form->submit('', array('type'=>'image','src' => 'img/buttons/buynow.gif'));  ?>

In Above code just replace ‘img/buttons/buynow.gif’ with your image path. It will show image and working as submit button.

Let me know if you have any problem in this.
