Constructor & Destructor Documentation

◆ __construct()

HTML_Template_ITX::__construct ( $root = '' )

Builds some complex regexps and calls the constructor of the parent class.

Make sure that you call this constructor if you derive your own template class from this one.

See also: HTML_Template_IT()

Definition at line 116 of file ITX.php.

References $root.

         $this->checkblocknameRegExp = '@' . $this->blocknameRegExp . '@';
         $this->functionRegExp = '@' . $this->functionPrefix . '(' .

Member Function Documentation

◆ addBlock()

HTML_Template_ITX::addBlock	(	$placeholder,
		$blockname,
		$template
	)

Adds a block to the template changing a variable placeholder to a block placeholder.

Add means "replace a variable placeholder by a new block". This is different to PHPLibs templates. The function loads a block, creates a handle for it and assigns it to a certain variable placeholder. To to the same with PHPLibs templates you would call set_file() to create the handle and parse() to assign the parsed block to a variable. By this PHPLibs templates assume that you tend to assign a block to more than one one placeholder. To assign a parsed block to more than only the placeholder you specify in this function you have to use a combination of getBlock() and setVariable().

As no updates to cached data is necessary addBlock() and addBlockfile() are rather "cheap" meaning quick operations.

The block content must not start with and end with this would cause overhead and produce an error.

Parameters

string	Name of the variable placeholder, the name must be unique within the template.
string	Name of the block to be added
string	Content of the block

Returns: boolean

Exceptions

ilTemplateException

◆ replaceBlock()

HTML_Template_ITX::replaceBlock	(	$block,
		$template,
		$keep_content = `false`
	)

Replaces an existing block with new content.

This function will replace a block of the template and all blocks contained in the replaced block and add a new block insted, means you can dynamically change your template.

Note that changing the template structure violates one of the IT[X] development goals. I've tried to write a simple to use template engine supporting blocks. In contrast to other systems IT[X] analyses the way you've nested blocks and knows which block belongs into another block. The nesting information helps to make the API short and simple. Replacing blocks does not only mean that IT[X] has to update the nesting information (relatively time consumpting task) but you have to make sure that you do not get confused due to the template change itself.

Parameters

string	Blockname
string	Blockcontent
boolean	true if the new block inherits the content of the old block

Returns: boolean

◆ setCallbackFunction()

HTML_Template_ITX::setCallbackFunction	(	$tplfunction,
		$callbackfunction,
		$callbackobject = `''`,
		$expandCallbackParameters = `false`
	)

Sets a callback function.

IT[X] templates (note the X) can contain simple function calls. "function call" means that the editor of the template can add special placeholder to the template like 'func_h1("embedded in h1")'. IT[X] will grab this function calls and allow you to define a callback function for them.

This is an absolutely evil feature. If your application makes heavy use of such callbacks and you're even implementing if-then etc. on the level of a template engine you're reiventing the wheel... - that's actually how PHP came into life. Anyway, sometimes it's handy.

Consider also using XML/XSLT or native PHP. And please do not push IT[X] any further into this direction of adding logics to the template engine.

For those of you ready for the X in IT[X]:

<?php ... function h_one($args) { return sprintf('

s

', $args[0]); }

... $itx = new HTML_Template_ITX( ... ); ... $itx->setCallbackFunction('h1', 'h_one'); $itx->performCallback(); ?>

template: func_h1('H1 Headline');

Parameters

string	Function name in the template
string	Name of the callback function
string	Name of the callback object
boolean	If the callback is called with a list of parameters or with an array holding the parameters

Returns: boolean False on failure.

Exceptions
