url() functions improvements

I’ve added useful addition for url(), url_user() and url_admin() functions.

Special params @object  @action  @id  @page  inserted from $_GET like this:

@object == $_GET[‘object’]

@action == $_GET[‘action’]

@id == $_GET[‘id’]

@page == $_GET[‘page’]

Examples:

url_user('/@object')
url_user('/@object/testme/4')
url_user('/@object/@action/@id/@page')
url_admin('/manage_users/@action/@id')

urls generation: url_user() and url_admin() functions added

2 new functions added to make project urls generation more simple and straightforward:

url_user() – intended to generate url for user section, no matter from where it was called

url_admin() – intended to generate url for admin section, no matter from where it was called

Examples:

url_user('/') 
url_user('/user/register')
url_admin('/template_editor/edit/main')

Also, these functions will generate url depending on rewrite enabled or not, if rewrite enabled – then result will be fully processed (http://host.dev/testme/some/1),

if rewrite disabled – then urlencoded string will be as result (http://host.dev/?object=testme&action=some&id=1)

 Unit tests added:
