Classe: HTML_Template_IT  - X-Ref

Integrated Template - IT

Well there's not much to say about it. I needed a template class that
supports a single template file with multiple (nested) blocks inside and
a simple block API.

The Isotemplate API is somewhat tricky for a beginner although it is the best
one you can build. template::parse() [phplib template = Isotemplate] requests
you to name a source and a target where the current block gets parsed into.
Source and target can be block names or even handler names. This API gives you
a maximum of fexibility but you always have to know what you do which is
quite unusual for php skripter like me.

I noticed that I do not any control on which block gets parsed into which one.
If all blocks are within one file, the script knows how they are nested and in
which way you have to parse them. IT knows that inner1 is a child of block2, there's
no need to tell him about this.

<table border>
<tr>
<td colspan=2>
__global__
<p>
(hidden and automatically added)
</td>
</tr>
<tr>
<td>block1</td>
<td>
<table border>
<tr>
<td colspan=2>block2</td>
</tr>
<tr>
<td>inner1</td>
<td>inner2</td>
</tr>
</table>
</td>
</tr>
</table>

To add content to block1 you simply type:
<code>$tpl->setCurrentBlock("block1");</code>
and repeat this as often as needed:
<code>
$tpl->setVariable(...);
$tpl->parseCurrentBlock();
</code>

To add content to block2 you would type something like:
<code>
$tpl->setCurrentBlock("inner1");
$tpl->setVariable(...);
$tpl->parseCurrentBlock();

$tpl->setVariable(...);
$tpl->parseCurrentBlock();

$tpl->parse("block1");
</code>

This will result in one repition of block1 which contains two repitions
of inner1. inner2 will be removed if $removeEmptyBlock is set to true which is the default.

Usage:
<code>
$tpl = new HTML_Template_IT( [string filerootdir] );

// load a template or set it with setTemplate()
$tpl->loadTemplatefile( string filename [, boolean removeUnknownVariables, boolean removeEmptyBlocks] )

// set "global" Variables meaning variables not beeing within a (inner) block
$tpl->setVariable( string variablename, mixed value );

// like with the Isotemplates there's a second way to use setVariable()
$tpl->setVariable( array ( string varname => mixed value ) );

// Let's use any block, even a deeply nested one
$tpl->setCurrentBlock( string blockname );

// repeat this as often as you need it.
$tpl->setVariable( array ( string varname => mixed value ) );
$tpl->parseCurrentBlock();

// get the parsed template or print it: $tpl->show()
$tpl->get();
</code>
