Maintain Your Site with Page Include Files

Maintain Your Site with Page Include Files by Larry (Momp) PochWe all know how web sites seem to take on a life of their own.As the number of pages increases maintaining the site can be atime consuming task...!The use of "Page Include" files makes the task of editing webpages a lot easier and faster. An additional benefit is that it reduces the size of a page, thus improving page load time. This article takes a brief look at three forms of "Page Include"files. CSS Includes, SSI Includes, and Javascript Includes.1.. (CSS) Cascading Style Sheet IncludesCSS can be used to format the page margins, font, link colors, and much more. Create a file in your text editor, and include all the common stylesheet declarations for your pages, now save the page with a .css file extension.Note: the declaration tags are not included in an external style sheet. This reference is in the Link Relevant tag used to call up the stylesheet.For this example we will call the stylesheet page "main.css". h1 {color: #ff0000; font-family: arial; font-size: 14px; text-decoration : underline; }p {font-family: verdana; font-size: 10pt; color: #ffffff; }td {font-family: verdana; font-size: 10pt; color: #ffffff; }a {font-family: arial; font-size: 10pt; font-weight: bold; }a:link {color: #0000ff; text-decoration: none; }a:visited {color: #800080; text-decoration: none; } a.menu:link {color: #ffffff; text-decoration: none; }a:hover {color: gold; text-decoration: underline; }In the tag area of the page the "main.css" stylesheet is called up using the LINK REL tag. Now when you want to add or change your page format, just edit this one file. The changes will appear on any page where the stylesheet is called up.For more on CSS see:http://www.mompswebdesign.com/css/index.htmlAOL Users Click Here --------------------2.. (SSI) Server Side IncludesSSI is a great way of controlling site content that appearson multiple pages across a web site.Requirements: 1..your web site server must have SSI enabled. 2..most web hosts require the SSI pages to have a file extension of .shtml in place of .html or .htm 3..the file extension used will depend on the operating system used on the web hosts server. Windows servers use .asp file extension. Windows script: Unix/Linux servers use .php file extension. Unix/Linux script: This example will build a navigation bar for the bottom of a page. My web host server is Linux so we will use the .php file extension.Create a file in your text editor and include the HTML code for the navigation bar. Now save the SSI page with a .php file extension. Any HTML coding can be used in a SSI file, but the file should only include the code for the specific item. We will name this file "bot_nav.php" and place it in a sub-directory called "ssi"

Now when you add a new page or section to your site and want to add it to the navigation bar you only have onepage to edit. The changes will appear where ever theSSI include page is called up. Note: when viewing the source code of the page where thescript is called up, the include page coding will appearjust as written in the SSI Include file. --------------------3..Javascript IncludesThe Javascript Include is very similar to the SSI Include inthe example above. The differences are in the way the codeon our javascript include page is written. For this example we will use the same navigation bar code as used above.Create a file in your text editor and include the HTML codefor the navigation bar. We then add some javascript codingto each line of the HTML code as well as opening and closingjavascript tags. The code for the javascript include page willlook like this:Note:The page must begin with Each page line must begin with document.writeln('Each page line must end with ');Now save the page with a .js file extension, "bot_nav.js".Now place the following code on the page in the location youwant the navigation bar to be rendered.Javascript is a very sensitive language, but you can include most HTML or javascript coding on the page. Here are some things to watch for. 1..you can not include javascript that has to access another file to run. DO NOT include the tags in the .js file, they are included in the location script code. 2..if your content contains a backslash "" it must be preceded by another backslash "\". 3..if your content contains an apostrophe (') it must be preceded by a backslash ('). 4..the most common reasons for script error messages are extra space at the end of a line, or missing characters.This is the same type of script used to syndicate content foruse on other sites. But to code a long article or web designtip by hand would take some time. I used a CGI script called"Master Syndicator" that codes the content for me. The scriptis available athttp://www.mompswebdesign.com/cgi-bin/prolinkz/pl.cgi?willmasterNote: whether using CSS, SSI, or Javascript Include pages be sureto upload them to your site in ASCII mode.Implimenting one or all three of these "Page Include" methodswill make maintaining and adding to your site a lot quicker andeasier. -------------------------------------------------Larry(Momp) owns Momp's Web Design and MWD News newsletter.
