This post is based on Robert Conner's code forCakePHP 1.x., and I made some changes to get it to work onCakePHP 2.x . The original post can be found here.Maybe some people have faced problems trying to send some content to the layout on CakePHP. By content I mean not only a simple string but a whole a piece of HTML code. To solve this, we can create a Helper on CakePHP 2.x, according to the following steps:
1. Create the Helper
On theViews/Helpers folder, you need to create the .php file for the helper. In this case we will call it LayoutHelper.phpclass LayoutHelper extends AppHelper { var $__blockName = null; function blockStart($name) { if (empty($name)) trigger_error('LayoutHelper::blockStart - name is a required parameter'); if (!is_null($this->__blockName)) trigger_error('LayoutHelper::blockStart - Blocks cannot overlap'); $this->__blockName = $name; ob_start(); return null; } function blockEnd(&$view){ $buffer = @ob_get_contents(); @ob_end_clean(); $out = $buffer $view->viewVars[$this->__blockName . '_for_layout'] = $out; $this->__blockName = null } function output($var) { if (isset($var) && $var != null) echo $var; } }
2. Setting up the content
For setting up the content that we want to send to the layout, we use the Helper$layout = $this->Helpers->load('Layout'); $layout->blockStart('custom_content');Right after this, we specify the content that will be sent to the layout
<div>Custom content</div>and we close the block
$layout->blockEnd($this);
3. Show the content
For showing the content on the layout, we add the following$layout = $this->Helpers->load('Layout'); $layout->output($custom_content_for_layout);As we can see, this is really simple and also very useful when trying to customize the content on the layout according to the view we are loading
