Joomla 1.0 approach to SEF-url

• 3rd party component required– SEFAdvance– OpenSEF – sh404SEF

• Each one uses different approach

• Need to maintain separate plug-in for each component.

Joomla 1.5 and SEF url

• SEF-url engine comes built-in with every installation of Joomla !– Works with/without mod_rewrite– Nice human-readable url

• Not as flexible as 3rd party component

• No url caching

sef-url in Joomla 1.5

• Backend config

• Specify menu title alias

• Some limitations– No choice over url suffix. One will be assigned

automatically. – Potential multiple link to the same content– If multiple menu item use the same link title,

only the first will be accessible

2 approach in SEF rewriting

• No caching, logic-based syetem.

• create and resolve url on the fly

• Cached url system

1. Non-caching

• (my preferred technique)• Able to resolve url that has never been used

before• Twice the amount of work to develop the plugins• Example

– OpenSEF– sefAdvance– Joomla 1.5 default– SmartSEF

2. Cached url system

• url are created and saved• Little overhead to parse the url, need a single

database call• Normally require only the code to ‘create’ the url• url has to be created first, otherwise it cannot be

resolved• Can break your site, damage your SEO ranking

when cached cleared– sh404SEF

Creating sef-url for your component

1. Plan your url

2. List down all your required normal url

3. List down how they should look like, SEF-ed

4. Tips1. “Human readable!”

2. Meaningful, with a hint of the content

3. Contain targeted keywords

1. Create a file ‘router.php’ in your component folder

2. Create 2 function within router.php1. function [Com name]BuildRoute( &$query )

2. function [Com name]ParseRoute( $segments)

…BuildRoute(&$query)

• Take a reference to an array

• $query is built from JRoute::_(…) function call, split-up into array

• Return value should be an array, – $segments = array()$segments[]=‘path1';$segments[]='path2';$segments[]='file';

– Will create path1/path2/file.html

• Need to unset all variables that you have assign a segment

Notes & gotchas

• Do not add ‘.html’ to your SEF url, Joomla will add this automatically if required.

• Create a menu entry to use component ‘alias’ . Otherwise, it will show as ‘/components/com_name/…’

• Alias has to be unique. If there is a duplicate, only the first link will be accessible

…ParseRoute($segments)

• Called to resolve the segment-based url to their original url

• Given an array with url segment

• Return array of actual $_GET values

Notes…

• Joomla convert the first dash ‘-’ to ‘:’

• There is no reliable way to encode/decode url that might contain combination of dash and double colon

• Where do we specify Itemid ? . Don’t worry, menu alias will take care of it!

Other alternative

• SmartSEF (www.smartsef.org)– Each sef plugin can have their own params– Sitemap support– Some security check

• SEFAdvance• Sh404

– H1 tags

• SEF Patch (joomlatwork.com)– (metadata/no-follow)
