Joomla! 2.5: Another LDAP (?) Issue

This one was really driving me crazy. Really.

But we can't blame LDAP for that, at least I don't think so...


We have a LDAP authentication set up which is working really well. Except when a user enters a wrong password - then he just gets a blank page. The same is the case for articles with a user restriction (user need to be logged in to view the article) - again, just a blank page.

Turns out the blank page is not as blank as it seems - the source is there, including a nice error message. And a line somewhere in the head saying

html{display:none;}

A lot of research took me to this page, and I decided to try the following, out of some instinct:

 "Comment out line 823 (or thereabouts) in:
libraries> joomla > html > html> behavior.php
$document->addStyleDeclaration('html { display:none }');
To comment out, just add 2 slashes "//" in front of the line."

 Works like a charm. I am afraid the change will be undone by the next Joomla update, but I'll try to report a bug. In the meantime I hope this helps. Happy coding!

edit: Someone reported a bug on a similar problem, seems like version 2.5.9 will not have this line any more. See here.

Joomla! 2.5: Multiple views, one model

Here goes MVC again: I was a bit confused that every time I created a second or third view for a component, I had to create a separate model for it. Did not make sense to me - I had the necessary algorithms in the model for the first view, did I really need to do copy & paste? I hate it! Redundancy, redundancy, redundancy. That case occurred in my current project - I created user profiles and needed an "edit" view. The data is the same, but I need to have the data in editable text fields instead of fixed labels, and maybe some other buttons here and there...  Well, some time later I realized that I just did not quite understand what Joomla! acutally means by "view".  And that there is something called "layout". Long story short: If you have a model that provides all necessary information and you just want to have a different presentation of it, just add a new .php file to your views/<yourviewname>/tmpl folder - let's call it "layo...

Joomla / Eclipse: Use Eclipse to edit files

Even though I could use any Editor or Notepad, after some days of Joomla! I was yearning for some syntax highlighting and maybe even automatic code completion... I did some Java programming in the past, and I am really used to the Eclipse IDE. Eclipse IDE for JavaScript Web Developers seemed to be a good deal for what I was up to do, so I gave it a try. I feel kind of stupid even posting about this, but upon starting up Eclipse, I started to wonder how I would do that - being that Eclipse works with projects, and I didn't want to put all of my components into an Eclipse workspace, and I didn't want to put up a subversioning system. Turns out it is quite simple: Right-click somewhere in the package explorer,  select 'New', 'Project...'. In the dialog, open the folder 'General' and select 'Project'. Click 'Next'. For the name, I usually put the com_componentname / mod_modulename, as in my file system. But I don't think it matters....

Joomla! 2.5: Component as Article

Can you put a component on a page together with other articles? Like, for example, to have a component and a blog layout on the "Home" page? Yes, you can! There are some nice extensions that allow for this. I used the "Plugin Include Component" plugin, which is available on extensions.joomla.org . With this plugin, you simply create an article that contains a special tag, indicating the component to include. Just like this: Install the plugin and put the following code in whatever article you need it in (substitute 'componentName' and 'viewname' for your component's and view's name...). {component url='index.php?option=com_ componentName &view= viewname '}
