After searching a bit on the WPML site, I found a code example where you are shown howto create your own language selector menu:
http://wpml.org/documentation/getting-started-guide/language-setup/custom-language-switcher/

I then wrote this function to get the current language of a site:

/**
 * Function for getting the active language of the WPML plugin
 * @return the currently active language, defaulting to 'en'
 */
function getActiveLanguage() {
  // fetches the list of languages
  $languages = icl_get_languages('skip_missing=N&orderby=KEY&order=DIR');

  $activeLanguage = 'en';

  // runs through the languages of the system, finding the active language
  foreach($languages as $language) {
    // tests if the language is the active one
    if($language['active'] == 1) {
      $activeLanguage = $language['language_code'];
    }
  }

  return $activeLanguage;
}
?>

Just add this code to the theme's functions.php file and you are ready to find the active language of your site!

The documentation states:

link_to(name, options = {}, html_options = nil)
link_to(options = {}, html_options = nil) do
# name
end

URL to the rails docs: http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#M001597

And gives a list of options you can set. However, I always seem to have problems remembering the correct syntax if I want to use :confirm and :method.

After fiddling with it a bit, I found that the proper way of using is:

<%= link_to(
  t("Delete"),
  {
    :action => "destroy",
    :id => some_id
  },
  :method => :delete,
  :confirm => t('Are you sure you want to delete it?')
) %>

My biggest problem was, that you do not need to add the controller.

Also, found a nice write up about this on Ryan’s Scraps blog (a bit old post, but still…)

Hope you can use the tip.

I thought to myself, why not use the built in server instead of installing a MAMP package?

Anyways, seconds went by and I found the option in the system preferences, turned on “web sharing” and excitedly headed on to localhost. It worked perfectly, now I just needed to set it up as it was on my linux desktop.

The apache’s httpd.conf file is located in the folder: /private/etc/apache2/httpd.conf
(I used textmate to edit the file.)

What I wanted to do was, since I’m the only user on this laptop, I wanted my Sites folder to have a www “folder”, which was a symlink to a folder in my Documents folder. The symlink would then point to the webapp I was currently coding.

This worked on my linux desktop, so it should also work here.

The first thing I did was to fix the DocumentRoot so it now points directly to my /Users/username/Sites/www folder (or actually the symlink, which we’ll create now).
The I added PHP support by removing the comments from line 116, containing:

LoadModule php5_module         libexec/apache2/libphp5.so

Then I went into my Sites folder and created a symlink to a folder in the Documents folder called “current_project” (yes yes, secret stuff here). This is done using the following command:

ln -s ~/Documents/current_project ~/Sites/www

After that, just reboot you apache server (you can use the Web Sharing option in the System Preferences. Just uncheck the web sharing checkbox and recheck it again).

An here my problems began. I got a lot of warnings in my apache error log (/private/var/log/apache2/error_log) saying:

Symbolic link not allowed or link target not accessible: /Users/username/Sites/www

After googling for a while with no answers, I thought : “why not disable the userdir module? I’m not going to use the localhost/~username anyways”

This turned out to do the trick.

The solution was simply to disable the userdir module in apache.
Comment out line 112 (LoadModule userdir_module libexec/apache2/mod_userdir.so) and line 465 (Include /private/etc/apache2/extra/httpd-userdir.conf)
Restart the apache server (web sharing thingy in the System preferences interface) and you server can now access the symlink.

I hope this will help you on your way, when coding using a Mac.

Small update: (2010-06-02 at 13:15)
Remember to right click the Documents folder and choose “Get Info”. Unfold “Sharing & Permissions” and set “Everyone” to “Read only”, else you will get a permission denied

I have even included an example when you start your server, once the base structure is installed. Go check it out on http://github.com/jimmiw/php-mvc-base

Since this really isn’t a big thing to do in prototypejs and if you use firebug you could inspect the event object in the dom yourself, I’ll just give you the script:

$(document).observe('keypress', function(e) {
  if(e.charCode==115 && e.ctrlKey) {
    e.stop();
    console.log('CTRL+s was called!');
  }
});
