<?php/* * OPTIC TEMPLATE LIBRARY * * Jan 1999-2000 Alexander Aulbach for Main Media * * $Id: layout_html.inc,v 1.2 2000/07/12 18:22:34 kk Exp $ * * This Lib is used for the default representation of a page. * It has to be extended for own layout-design * * The class needs the strings2.inc function-set!! include it with * include("strings2.inc"); * * * This lib was written from the need to implement a user-defined * home page design. The user could choose how the server should looks * for him/her. He/she could choose, for the background color, the * color of the tables, the size of the fonts and so on and so on. * First I thought this would be possible to implement it with Style Sheets * but there is no way to make it as flexible as it needs to. * So the idea was born to make this class, which generates the design * on the fly. * * There is NO NEED to use it for everything. Cause it makes things * more difficult to handle. But it is a great help for some special * kind of use, especially for programming sites, where the user can * choose his layout, like for personalized community pages. * * It's also a great help for programmers of a web site. They can just begin * to make their programs and output tons of lists etc. * They don't have to care about the colors and placement, cause the * layout could be fixed later. * * The advancement to e.g. FastTemplate is, that every little piece of HTML * code has some default representation, which can be changed _dynamically_. * It produces also correct HTML code, if you only use the functions. * * For me especially the doc_picture()-function is a great help, cause * I never have to care about the size of the images (The WIDTH and HEIGHT * attributes). * Our designer says "Oh, Alex, before I forget: I have changes the size * of hugo.gif a little bit, could you fix it in your code?" * And I answer: "It's already fixed. Totaly automatically. :-)" * * The disadvantage is of course, that the pages are generated dynamically, * so it is not fast. * * Best efficency can be achived while using BOTH of them, mixing it * up as you need it. * * * * Ideas for later programming: * - implementing an unsorted list with the originial tags not with tables * * - It would be a nice idea to mix the both advantages of FastTemplate and * Layout. There is just a need for a kind of buffer mechanism. Like this * from "Story Server". If the layout exists and is uptodate, then get * the template and use FastTemplate. If not create template with Layout * and store it for next use. * * - Cause this is a class, you can take care, if the functions are * called in the propper order and closings * */class Layout { ## ## ## var $Debug = false; ## ## these vars are needed for generating an IMG-Tag ## layouturl: s.th. like "http://hugo.bla/" ## layoutpath: if empty it will be set on first call to $DOCUMENT_ROOT ## var $layouturl = ''; var $layoutpath = ''; ## ## In most cases only the following definition-section ## must be changed ## ################################################# BEGIN var $docbegin ='<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"><HTML><HEAD>'; ################################################# HTMLHEAD var $htmlhead = ARRAY ( 'TITLE' => "<TITLE>%s</TITLE>\n", 'stylesheet' =>' <style type="text/css"> <!-- body { font-size: 20pt font-family: geneva,Arial,Helvetica,helv,swiss; } td { font-family: geneva,Arial,Helvetica,helv,swiss; } a:visited { text-decoration: none; } a:link { text-decoration: none; } a:active { text-decoration: none; } p { font-size: 20pt ; line-height: 10pt; font-family: geneva,Arial,Helvetica,helv,swiss; fontfamily: geneva,Arial,Helvetica,helv,swiss; } lighthead { font-size: 12pt ; line-height: 10pt; font-family: geneva,Arial,Helvetica,helv,swiss; fontfamily: geneva,Arial,Helvetica,helv,swiss; color: #EEEEEE } --> </style>'); var $htmlhd_def = ARRAY( 'TITLE' => '', 'PRETITLE' => '' ); ## ## For stylesheets we must add ## ID, CLASS, STYLE, LANG and DIR ## to nearly every element!
