# OnTheGoSystem Resources loader master branch

We have code and resources in GIT for branding of our plugins.
https://www.onthegosystems.com/misc_svn/onthegosystems-branding/

It contains icons (as fonts) and colors for Toolset plugins.

For example the menu icons and icon and color of popups.

## Including the code:

Plugins can include this code via SVN externals.

## Loading code and resources:

The loader.php should be included early in the main plugin.php file. Then the onthego_intialize function should be called. The onthego_intialize function should be passed the file path to the directory where loader.php is and the URL to the directory where loader.php is.

      require PATH_TO_ONTHEGO_RESOURCES_DIR . 'loader.php';
       onthego_initialize(PATH_TO_ONTHEGO_RESOURCES_DIR, URL_TO_ONTHEGO_RESOURCES_DIR);
 
### Loading the latest version of the resources when multiple plugins use the code:

Normally the first plugin that runs its code will determine what resources get loaded. 

loader.php is responsible for loading the latest version of the resources. The loader.php has a version number and keeps a record of the path and url for that version of the code.

Then after all the plugins code are loaded it uses the ‘plugins_loaded’ hook to then find the latest version of the code and then uses the matching path to load further php files and the matching url for loading the resources.

This way a user can have various versions of the onthego branding resources in his plugins but the code will always ensure that the latest version is used.


         // This version number should always be incremented by 1 whenever a change
             // is made to the onthego-resources code.
             // The version number will then be used to work out which plugin has the latest
              // version of the code.
         
        $onthegosystems_branding_version = 1;
