Introduction

PHPTAL is a PHP implementation of ZPT work. To be short, PHPTAL is a XML/XHTML template library for PHP.

While most web developpers continue to use ASP/JSP/PHP tags as the core language of their templates, the Zope community came with a refreshing idea named TAL. The idea was to move presentation actions inside XHTML attributes instead of using plain tags or elements.

Let's start with a simple PHP exemple (usually reproduceable in ASP/JSP):

<?php foreach ($values as $value): ?>




<div>




  <div>




    <?php if ($value->hasDate()): ?><?=$value->getDate()?><?php endif; ?>




    <a href="<?= $value->getUrl() ?>"><?=




		htmlentities($value->getTitle())




	?></a>




  </div>




  <div>




    <?= htmlentities($value->getContent()) ?>




  </div>




</div>




<?php endforeach; ?>

Let's have a look at the TAL way:

<div class="item" tal:repeat="value values">




  <div class="title">




    <span tal:condition="value/hasDate" tal:replace="value/getDate"/>




    <a tal:attributes="href value/getUrl" tal:content="value/getTitle"/>




  </div>




  <div id="content" tal:content="value/getContent"/>




</div>

Now it's up to you to choose which version you prefer. Of course those tal:condition, tal:replace and tal:repeat may looks strange when begining with TAL.

Just for fun let's modify this example:






<div class="item" tal:repeat="value values">




  <div class="title">




    <span tal:condition="value/hasDate" tal:replace="value/getDate">




      2013-08-05




    </span>




    <a href="sample.html"




      tal:attributes="href value/getUrl"




      tal:content="value/getTitle">




      My item title




    </a>




  </div>




  <div class="content" tal:content="value/getContent">




    This is a sample content which is replaced by the




    real content when the template is run with real




    data.




  </div>




</div>
