HYPERTEXT TEMPLATE CLASS (httclass.php)
- Author: Joseph E. Albritton
- License: Public Domain
- Warranty: None, use at own risk
- Background: Based on the ParseTemplate class of WinSysInfo 1.21
=====================================================================================================
INTRODUCTION
- Hypertext as defined here, is client-side browser renderable code, ie. HTML, SCRIPT, CSS
- A .htt file consist of one or more named sections of hypertext
- A section of hypertext is delimited by the [/SECTION\] and [\SECTION/] tags, where SECTION is the name
- A section of hypertext may contain any number of three different types of replacement tags
[|FILE|] - replaced automatically by the content of FILE name
[[SECTION]] - replaced automatically by the content of SECTION name
[REPLACE] - replaced by calling the Replace() method
=====================================================================================================
PURPOSE
- Provide flexibilty in how hypertext is used by creating separate, reusable, named sections
- Reduce script size and complexity by moving static hypertext into a .htt file
- Reduce redundant hypertext by using automatic replacement section tags
- Change how data is presented by using different .htt files
- Provide tags to be replaced automatically with the content of a file
- Provide tags to be replaced automatically with the content of a section
- Provide tags to be replaced with user defined data

EXAMPLE SCRIPT USING HTTCLASS.PHP (test.php)
<?php

echo $oHtt->Get( "HEAD" );
$oHtt->Replace( "[DATA]" , "Auto TABLE Section" , "BODY" );
$oHtt->Replace( "[TABLE]", $oHtt->Get( "TABLE" ) , "BODY" );
$oHtt->Replace( "[DATA]" , "Another TABLE Section", "BODY" );
echo $oHtt->Get( "BODY" );
echo $oHtt->Get( "FOOT" );
}
