Try having a look here : http://docs.joomla.org/How_to_override_the_output_from_the_Joomla!_core

 

Think this is what you are looking for. You can also take a look in the default templates. Here you will find af html folder. This is how you are able to display content in a customized way.

Hey Michael,

Thank you for the link, but this is not what I'm looking for.

In j1.6 and 1.7 we are presented with the jform class. Trough a configuration file that resides in models/forms - we define what fields our forms will have, what classes they have, what kind of input is allowed etc... I'm searching for a way to override this file and from what I've found so far - you can't override this file with a template override.

 

Cheers,

Daniel

Ohh i see and no you are right as far as i know. But what you need to do then is to extend the JFormField class

 

Here's what you do :

1. Go to your models folder (administrator/components/com_COMPONENTNAME/models/).

2. Create a new folder and call it fields. In this folder you can create your custom fields for JForm.

3. The name you give this file is the name that you put in the form (.xml file)

 

Take a look at the administrator part of com_modules or com_banners to see examples (administrator/components/com_modules/models/fields/)

 

Hope that helps

Hi,

 

i dont know if there is a better solution, but you could write a plugin and use one of the appropriate events (onContentPrepareForm, onContentPrepareData, dont know if they work good with com_contact though) to hook in, then you can just define your own xml and in that xml define the fields exactly like in the xml you want to override (including <fieldsets> etc).

Thats how i did that overriding some registration fields.
