Introduction --  What HTML_Template_Flexy can do


HTML_Template_Flexy started its life as a simplification of HTML_Template_Xipe, However the long term aim of Flexy is to provide a universal Template Base API for Compiling and native PHP type templates.

Flexy currently supports a number of backends (Template Formats), and is designed to be extended to support more, The Key Formats are:

Data can be assigned in two ways with flexy, depending on your preferred style of working.

With all this Flexibility, it still manages to achieve

How does HTML_Template_Flexy differ from other template systems

If you look around you will see there are other template systems available in PHP, they generally fall into two categories, Replacement Systems, or PHP Code builders.

Replacement systems like HTML_Template_IT, FastTemplate, PhpLib Template tend to be slower at doing block and nested block type templates and involve alot of code to add each variable to the template.

Php Code builders like Flexy, Smarty, SimpleTemplate (now HTML_Template_Xipe) tend to be better at more complex templates, and can offer a better approach to extendability. (the long term aim of Flexy is to integrate support for all of these PHP Generator templates into a simple package)

The Standard Compiling Backend uses a Tokenizer, which offers the possiblities of using HTML tags and attributes to provide looping and conditionals, and make dynamic XML_Tree like elements of HTML Forms that can be manipulated in your code. (This conversion is only done once when the template compiles)

Typical use example

Flexy template is normally called from within a Controller Class (in the Model,View,Controller paragam). You just send HTML_Template_Flexy, the name of the template, and the object to output. - any variable you want printing out just has to be set in the object being used to ouput.

Example 47-1. Typical usage example for HTML_Template_Flexy


/* configure the application - probably done elsewhere */
require_once 'HTML/Template/Flexy.php';
require_once 'PEAR.php';
$options = &PEAR::getStaticProperty('HTML_Template_Flexy','options');
$config = parse_ini_file('example.ini',TRUE);
$options = $config['HTML_Template_Flexy'];

/* the page controller class */

class controller_test 

    var $template = "home.html"; // name of template
    var $title;                  // this relates to {title};
    var $numbers = array();      // this relates to {numbers} , used with foreach
    var $anObject;

    var $elements = array();      // this is where the elements are stored

    /* start section - deals with posts, get variables etc.*/

    function controller_test() 

    function start() 
        // the title
        $this->title = "Hello World";

        // store an object.
        $this->anObject = new StdClass;

        // assign a value to a member.
        $this->anObject->member = 'Object Member';

        // if you need form elements - you have to include them.
        require_once 'HTML/Template/Flexy/Element.php';

        // create an HTML Element for the form element.
        $this->elements['input'] = new HTML_Template_Flexy_Element;

        // assign a value to it

        for ($i = 1;$i< 5;$i++) {
            $this->numbers[$i] = "Number $i";

    /* output section - probably best to put this in the default_controller class */

    function output() {
        $output = new HTML_Template_Flexy();

    function someMethod() {
        return "<b>Hello From A Method</b>";


/* the page controller instantaation - probably done with a factory method in your master page controller class */

new controller_test();


Now the example template,

And the output
