addBlock() – Adds a block to the template

Synopsis

require_once 'HTML/Template/Sigma.php';

mixed HTML_Template_Sigma::addBlock ( string $placeholder , string $block , string $template )

Description

Adds a block to the template changing a variable placeholder to a block placeholder. This means that a new block will be integrated into the template in place of a variable placeholder. The variable placeholder will be removed and the new block will behave in the same way as if it was inside the original template.

The block content must not start with <!-- BEGIN blockname --> and end with <!-- END blockname -->, if it does the error will be thrown.

Parameter

Return value

return SIGMA_OK on success, error object on failure
