Extensive tutorial on layout overrides

masterchief · **Posted:** Mon Jul 07, 2008 1:53 am

I've done an extensive tutorial on layout overrides (and a few other things) on the developer site:
http://developer.joomla.org/tutorials/3 ... oomla.html

Hope people find it useful and if there is anything missing or anything is unclear let me know.

Great article, thanks!

- Does the override apply to Admin templates as well?
- Can any file be overridden and not just View files? e.g. Helper or Controller files?

TIA

You can override the layouts of the admin components only if they'd been MVC'd. Many are still in the old format.

Helpers and controllers cannot be overridden, no.

No idea. You'd have to ask ZenCart.

I want to override the output for the com_content in the admin section.

Is this possible?

I've looked at the folder structure and it has a model and view folder, but not a controller folder. So is this in MVC format?

Thanks

It's not really practical to override backend com_content in 1.5 unfortunately.

is it possible too create a complete outsourced landing page out of a component.
I want to use some functions of joomla like registering users and administration of this landing pages e.g. adding location ids. Is a component a good approach for that? I mean the template should be completey different to joomlas. Can this be done with override directory structure?

So, it is possible to make a frontend component layout showed just like the backend one. Like this,

What about the toolbar and the table style?

@fahmi_priadi

I don't know what you mean.

I'm sorry, my english is not good.

I want to create a frontend component which capable to show a list of data, and input data to the list, just like the Article Manager. I've read Learning Joomla! 1.5 Extension Development book, but the book only tell me how to make the Restaurant Review Manager at the backend.

Can you give me a suggestion, which book or article that i should read to solve my problem?

Thank You

Ok, now I understand. You can apply the same principles for a backend component in the frontend. You don't have a toolbar on the frontend but have a look how com_content frontend handles article submission - that will give you some clues.

Ok, thank you very much.

Um, i'm sorry, i've already checked the com_content. But it seems that you've misunderstood the toolbar that i mean. Here is the picture of the toolbar and table list that i mean,

It is not an actual joomla! webpage, I made the picture using paint.
Sorry to bother you, but i really appreciate your help.

Ok, that is technically possible using layout overrides, but it would take a fair bit of work to do (too much to explain here). Probably something you are going to have a lot of trial and error with.

A very good tutorial.... but there isnt a plugin override in general, right?
for example pagebreak.php....

If any developer can confirm this I 've made a post in http://forum.joomla.org/viewtopic.php?p=1605175#p1605175

I 've uploaded a hacked update for the JPluginHelper class but the official joomla developers must check the file and make fixes...

No, there's no plugin override because they don't work that way. If you want to do that copy the plugin to make a new one and turn the old one off. Simple

Strange, the view of plugins should be separated some how from their functionality, like the MVC in components... but with little code added in JPluginHelper I added plugin override capability per template (my previous post)...

thank you for your immediate reply masterchief.....

Plugins don't have views and they serve a wide variety of purposes. That said, you could theoretically write a content plugin to support templates of a sort. The pagebreak one though, I'd actually turn that one into JHtml helpers myself rather than using a plugin.

Oh, ok masterchief now I got it, thank you very much for this, there is a lot of confusion around plugins. I 'll use of course your first solution "create a new version for the plugin"....

thank u once more for your immediate response...

a 'layout override'? If so how does it work ?

I second and third that! Just like pagination, it's one of those elements that designers'll want to control!

Hopefully the developers pick up on this and add it in future versions!
