WordPress – Return URL

October 2nd, 2008 by Frank • WordPress Hacks • 2 Comments

I already talked in my article Determine Path To Plugin and Content Directories about the possibilities how to keep functions in themes or Plugins free from error if you rename a folder, for example wp-content.

Since version 2.6 you can also solve this problem pretty easy with another function.
More details and information are available in /wp-includes/link-templates.php.

Return the site url

Returns the 'site_url' option with the appropriate protocol, 'https' if is_ssl() and 'http' otherwise.
If $scheme is 'http' or 'https', is_ssl() is overridden.

$path - Optional path relative to the site url
$scheme Optional scheme to give the site url context. Currently 'http','https', 'login', 'login_post', or 'admin'

site_url($path = '', $scheme = null)

Return the admin url

Returns the url to the admin area.

$path - Optional path relative to the admin url

admin_url($path = '')

Return the includes url

Returns the url to the includes directory.

$path - Optional path relative to the includes url

includes_url($path = '')

Return the content url

Returns the url to the content directory

$path - Optional path relative to the content url

content_url($path = '')

Return the Plugins url

Returns the url to the Plugins directory.

$path - Optional path relative to the Plugins url

plugins_url($path = '')

At version 2.8 of WordPress you can use two parameter. Use $plugin with __FILE__ for scan your folder.

plugins_url($path = '', $plugin = '')

Examble for Pluginpath

The follw code load a javascript from the Plugin in folder examble_plugin_folder.

wp_enqueue_script( 'farbtastic', plugins_url('/examble_plugin_folder/includes/farbtastic/farbtastic.js'), array('jquery'), '1.2' );

I hope you enjoy this alternative. please comment for a better idea or a other ways to do it.
