how to generate url friendly in Joomla ?

Answer 1

You should just work with normal url's in your code. when you turn on SEF joomla! will automaticly convert all links you create to SEF urls and when a request comes in it will revert them back to regular url's for you...

Answer 2

It's a little convoluted, but the proper way to link to SEF URLs is to use the original, non-SEF link. You will need:

• The ID of the article
• The Itemid of the menu item for your section (e.g. the menu item linking to Article Blog layout, etc)

Then you just link to:

index.php?option=com_content&view=article&id=42&Itemid=3

Where 42 is the article ID and 3 is the menu ID.Your link will then look something like:

/section-alias/42-the-article-alias

If you miss off the Itemid your link will look like this (I think):

/components/content/42-the-article-alias
