addBlock()
Synopsis
mixed HTML_Template_Sigma::addBlock ( string $placeholder , string $block , string $template )
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
- string $placeholder
-
name of the variable placeholder, the name must be unique within the template.
- string $block
-
name of the block to be added
- string $template
-
content of the block
Return value
return SIGMA_OK on success, error object on failure
