TOPIC: how to develop an extension

how to develop an extension 17 years, 6 months ago #75

  • divivo
Hi,

I would like to develop an extension for Acajoom component. Where do I get started. Is there a documentation or example on how to develop a third party extension for JoomSEF.
Thanks in advance
chris

Hello Chris,

we are sorry, but so far there is no documention for developing 3rd party extensions ready. We still plan to do some major changes in the object model, so maybe we write some after that.

As regards example, you can use some of the models in /sef_ext directory. E.g. DocMan or Joomlaboard.

Basically, what you need to create a new extension is:
  1. create a new file named same as the module you are writing the ext for
  2. build the desired SEF path using the values from the module (so probably you read some data from module tables here etc.) and variables from the original URL that you can get by extract($vars); command, such as IDs and similar; the final path should be prepared in an array, e.g. named fields (each member is one level in SEF URL)
  3. when your path is prepared, just call: $string = sef_404::sefGetLocation($string, $title, $task, (isset($limit) ? @$limit : null), (isset($limitstart) ? @$limitstart : null), (isset($lang) ? @$lang : null));, where $title is your prepared path array, string is the original URL (is handed automatically, just leave it as it is); if desired, $task may be set to null; if$taskt is empty, then path is composed just from $title, otherwise task is appended to it


Well and that is it. It is no big deal, really.

If you write a new ext yourself, please send it to us, so we can add it to the installation package.

Honza<br><br>Post edited by: jan, at: 2006/09/05 02:02

Honza,

that's great very useful. the file will be install in the SEf component extension folder. There is nothing to install in my component, is that correct?
Thank you for your complete answer
Chris

Hi Chris,

wel in fact there are 2 possibilities where to put your SEF extension.

    [li]First, the SEF engine will search in the root directory of the component for file named sef_ext.php[\li]
  1. If such file is not found, then /sef_ext dir in the JoomSEF component is searched for file named com_(module name).php
  2. If neither of those files is found, then a standard SEF handler will be used, unless the SEF is disabled for the module in question


Have a nice day,
Honza

Re:how to develop an extension 16 years, 9 months ago #2278

Hello Jan,

I succesfully developed a custom extension for the component RapidRecipe!

In the Example is an error, it should be:
$string = sef_404::sefGetLocation(...)

instead of:
$string = JoomSEF::sefGetLocation(...)

btw: Will it increase the Speed when I uninstall the included extensions like &quot;alphaconten&quot;, &quot;docman&quot; etc? I don't need all of them.

Regards, Nino
