Introduction -- Creating and Parsing templates
Placeholder
The format of placeholder is
This means, the name of the placeholder can consist of upper- and lowercase
letters, underscores and hypens. The name must be placed between curly
brackets without any spaces. Valid names are i.e.:
| {Placeholder} |
| {place2_holder} |
| {PLACEHOLDER1} |
| {Place-Holder} |
Non-valid names are i.e.
| { Placeholder 3 } (spaces) |
| {place*holder} (char isn't permitted) |
Blocks
The format of a block is
<!-- BEGIN [0-9A-Za-z_-]+ -->
... block content ...
<!-- END [0-9A-Za-z_-]+ --> |
The rules for the block name are the same like for placeholders.
In contrast to placeholders the spaces in the block markup are
required.
The nesting of blocks is permitted, but be careful while
parsing. You have to set and parse the deepest inner block first
and then set and parse from inner to outer.
In IT the whole template file itself is nested in a virtual block called
"__global". Most block-related functions use this block
name as default.
Usage Example
Example 31-1. The template <html>
<table border>
<!-- BEGIN row -->
<tr>
<!-- BEGIN cell -->
<td>
{DATA}
</td>
<!-- END cell -->
</tr>
<!-- END row -->
</table>
</html> |
|
Example 31-2. The script <?php
require_once "HTML/Template/IT.php";
$data = array
(
"0" => array("Stig", "Bakken"),
"1" => array("Martin", "Jansen"),
"2" => array("Alexander", "Merz")
);
$tpl = new HTML_Template_IT("./templates");
$tpl->loadTemplatefile("main.tpl.htm", true, true);
foreach($data as $name) {
foreach($name as $cell) {
// Assign data to the inner block
$tpl->setCurrentBlock("cell") ;
$tpl->setVariable("DATA", $cell) ;
$tpl->parseCurrentBlock("cell") ;
}
// Assign data and the inner block to the
// outer block
$tpl->setCurrentBlock("row") ;
$tpl->parseCurrentBlock("row") ;
}
// print the output
$tpl->show();
?> |

Example 31-3. The output <html>
<table border>
<tr>
<td>
Stig
</td>
<td>
Bakken
</td>
</tr>
<tr>
<td>
Martin
</td>
<td>
Jansen
</td>
</tr>
<tr>
<td>
Alexander
</td>
<td>
Merz
</td>
</tr>
</table>
