WordPress offers many ways to access the names of its folders and build new ones. Here is a helpful list with examples performed, to be more clear, from a subfolder located in a hypothetical plugin:
Plugins
Let's start with plugins_url() useful to determine and build url when you write a plugin.
plugins_url ()
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php plugins_url ( ) ; $ R = plugins_url (); / / Http://www.miosito.com/wp-content/plugins/ plugins_url ( 'myscript.js' , __FILE__ ) ; $ R = plugins_url ('MyScript.js', __ FILE__); / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/myscript.js plugins_url ( 'assets' ) ; $ R = plugins_url ('assets'); / / Http://www.miosito.com/wp-content/plugins/assets trailingslashit ( plugins_url ( 'assets' ) ) ; $ R = trailingslashit (plugins_url ('assets')); / / Http://www.miosito.com/wp-content/plugins/assets/ |
plugin_dir_url ()
This function is a variant of the above.
1 2 3 4 5 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php plugin_dir_url ( __FILE__ ) ; $ R = plugin_dir_url (__ FILE__); / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/ |
plugin_dir_path ()
This is substantially similar to plugin_dir_url() , returns the path on the filesystem. Retrieve the path to the file system is useful and necessary for example when we have to perform the include() . The format paths http , however, are useful and necessary when we have to load scripts, styles, css, images and so on can be reached by your browser.
1 2 3 4 5 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php plugin_dir_path ( __FILE__ ) ; $ R = plugin_dir_path (__ FILE__); / / / Var/www/clients/client2/web18/web/wp-content/plugins/my_plugin/classes / |
In fact can be considered an alias of return trailingslashit( dirname( __FILE__ ) );
plugin_basename ()
1 2 3 4 5 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php plugin_basename ( __FILE__ ) ; $ R = plugin_basename (__ FILE__); / / My_plugin / classes / test.php |
Themes
Let's see the features related to the themes.
get_theme_root_uri ()
Returns the url of the theme. , che nel nostro caso è http://www.miosito.com/ , e un parametro non considerato passato alla stessa get_theme_root_uri() This function applies a filter theme_root_uri with two additional parameters: the address of the site is stored in the option siteurl , which in our case is http://www.miosito.com/ , and not considered a parameter passed to the same get_theme_root_uri()
1 2 3 4 5 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php get_theme_root_uri ( ) ; $ R = get_theme_root_uri (); / / Http://www.miosito.com/wp-content/themes |
get_theme_root ()
This is the variation over to the filesystem. Although this uses a filter theme_root .
1 2 3 4 5 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php get_theme_root ( ) ; $ R = get_theme_root (); / / / Var/www/clients/client2/web18/web/wp-content/themes |
get_theme_roots ()
This returns either a string with the theme folder, if one, or an array of topics.
1 2 3 4 5 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php get_theme_roots ( ) ; $ R = get_theme_roots (); / / / Themes |
WordPress
These functions return a number of key locations and useful.
home_url ()
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php home_url ( ) ; $ R = home_url (); / / Http://www.miosito.com admin_url ( ) ; $ R = admin_url (); / / Http://www.miosito.com/wp-admin/ site_url ( ) ; $ R = site_url (); / / Http://www.miosito.com content_url ( ) ; $ R = content_url (); / / Http://www.miosito.com/wp-content includes_url ( ) ; $ R = includes_url (); / / Http://www.miosito.com/wp-includes/ wp_upload_dir ( ) ; $ R = wp_upload_dir (); / / This returns an array key pair thus formed 6 ) { array (6) { ] => string ( 61 ) "/var/www/clients/client2/web18/web/wp-content/uploads/2012/04" ["Path"] => string (61) "/ var/www/clients/client2/web18/web/wp-content/uploads/2012/04" ] => string ( 49 ) "http://www.miosito.com/wp-content/uploads/2012/04" ["Url"] => string (49) "http://www.miosito.com/wp-content/uploads/2012/04" ] => string ( 8 ) "/2012/04" ["Subdir"] => string (8) "/ 2012/04" ] => string ( 53 ) "/var/www/clients/client2/web18/web/wp-content/uploads" ["Basedir"] => string (53) "/ var/www/clients/client2/web18/web/wp-content/uploads" ] => string ( 41 ) "http://www.miosito.com/wp-content/uploads" ["Baseurl"] => string (41) "http://www.miosito.com/wp-content/uploads" ] => bool ( false ) ["Error"] => bool (false) } |
Multisite
These are features that were introduced with the release of WordPress 3.0, when WordPress MU (Multisite) was merged with WordPress.
get_admin_url ()
di un dato sito. This supports the filter admin_url and returns the administration folder wp-admin of a given site. Almost all of these functions, in fact, accept (optionally) as the first parameter the ID of the blog.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | / / If this line is performed by / / Http://www.miosito.com/wp-content/plugins/my_plugin/classes/test.php get_admin_url ( ) ; $ R = get_admin_url (); / / Http://www.miosito.com/wp-admin/ get_home_url ( ) ; $ R = get_home_url (); / / Http://www.miosito.com get_site_url ( ) ; $ R = get_site_url (); / / Http://www.miosito.com network_admin_url ( ) ; $ R = network_admin_url (); / / Http://www.miosito.com/wp-admin/ network_site_url ( ) ; $ R = network_site_url (); / / Http://www.miosito.com network_home_url ( ) ; $ R = network_home_url (); / / Http://www.miosito.com |
Thanks strategic useful!
