<h2>Extend for templates configuration</h2>

<h3>Goal</h3>
<p>Define replacement conditions for each template from template-extension
(template called "replacer").</p>

<p>"original template" from ./template/yoga (or any other than yoga)
 will be replaced by a "replacer" if the replacer is linked to this "original template"
 (and optionally, when the requested URL contains an "optional URL keyword").</p>

<p>"Optional URL keywords" are those you can find after the module name in URLs.</p>

<p>Therefore "Optional URL keywords" can be an active "permalink" 
(see permalinks in our documentation for further explanation).</p>

<p>Read: `<a href="#warnings">Warning</a>` usage conditions.</p>

<h3>What are template extensions?</h3>

<p>This configuration tool is powerfull for beginners and advanced users.
By FTP, in the template-extension folder, the Webmaster can duplicate a lot of
 the distributed .tpl files ("original template") with a different name 
 ("replacer").
 
 "Original templates", current original supported templates are:</p>
<ul>
  <li><span class="filename">index.tpl</span></li>
  <li><span class="filename">mainpage_categories.tpl</span> and/or <span class="filename">thumbnails.tpl</span></li>
  <li><span class="filename">menubar.tpl</span></li>
  <li><span class="filename">header.tpl</span> and/or <span class="filename">footer.tpl</span></li>
  <li><span class="filename">picture_content.tpl</span> and/or <span class="filename">picture.tpl</span></li>
  <!-- <li><span class="filename">slideshow.tpl</span></li> -->
  <li><span class="filename">profile.tpl</span> and/or <span class="filename">profile_content.tpl</span></li>
  <li><span class="filename">tags.tpl</span></li>
  <li><span class="filename">upload.tpl</span></li>
  <li><span class="filename">about.tpl</span></li>
  <li><span class="filename">popuphelp.tpl</span></li>
  <li><span class="filename">search.tpl</span> and/or <span class="filename">search_rules.tpl</span></li>
  <li><span class="filename">nbm.tpl</span> and/or <span class="filename">notification.tpl</span></li>
  <li><span class="filename">identification.tpl</span> and/or <span class="filename">register.tpl</span></li>
  <li><span class="filename">redirect.tpl</span></li>
</ul>

<h3>Where can I find "original templates"?</h3>

<p>Distributed original templates are in template/yoga/ 
(don't edit them in place for upgrade perspectives). So with "original templates", 
any webmaster can create his "replacers (customized templates)".</p>

<h3>Where should I save "replacers"?</h3>

<p><strong>Replacers (customized templates)</strong> must be placed in the 
template-extension folder (or its subfolders).
Replacers can have any filename with the .tpl extension. For example: <span
class="filename">template-extension/my-extension/video.tpl</span>.</p>


<h3>How can I activate my "replacers"?</h3>
<p>An <strong>original template</strong> should be assigned to each
 <strong>replacer (customized templates)</strong> to activate the related replacements.
 This is the goal of "Extend for templates" in the Configuration Administration menu.</p>

<p>If you select an <strong>optional URL keyword</strong> then replacements 
will be operate only on pages with this keyword. For example: <span
  class="pwgScreen">index.php?/<strong>most_visited</strong></span></p>
  
<p>Advanced users will use permalinks as <strong>optional URL keyword</strong>. </p>

<p>If you select a <strong>Bound template</strong> then replacements will be operate only on this template.</p>

<h3>How can I deactivate my "replacers"?</h3>
<ul>
<li>Unselect related "Original templates".</li>
<li>By FTP delete of "replacers".</li>
</ul>

<h3>Warnings</h3>
<ul>

  <li><strong>Original template</strong> must be the "original" template 
  otherwise you could have unpredictable results!</li>

  <li>On several <strong>replacers (customized templates)</strong> with the
  same<strong>Original template</strong> and the same <strong>optional URL 
  keyword</strong> only the last replacer is active.</li>

  <li>Unselected <strong>optional URL keyword</strong> will active the replacer
  on any template usage. As previous point, order can override previous
  selected replacers.</li>

  <li>Subfolders:
Subfolders are ignored but they are usefull to change current order.<br />
distributed-samples: for test purpose are distributed! 
<strong>Don't edit them</strong> create your own ones.
</li>

  <li>On delete of a replacer the <strong>Original template</strong> is 
  immediately reactivated.</li>

</ul>
