Dynamic Hostname

ຄຳອະທິບາຍ

This plugin changes dynamically and automatically the host name which WordPress uses. For example, when you run WordPress on your different servers, for production, development or staging, the host name will be changed dynamically and each site won’t have broken links. It’s very useful when you use it with Vagrant Cloud.

Some features

• Temporarily changes the host name to the current host name ($_SERVER[‘HTTP_HOST’]).
• Also replaces the host name of the links to the contents and the images in the same site.
• The host name included in the contents on the development server will be changed to the one for the production server. (You don’t need to replace the host name in the database when you move it to the production server.)
• The host name in the editor window is temporarily replaced with the current host name, so when you edit some on the development server, you never have broken links.

Hooks to use for replacing

This plugin uses the filter hooks below to replace the host name in URL.

$hooks = array(
    "home_url",
    "site_url",
    "stylesheet_directory_uri",
    "template_directory_uri",
    "plugins_url",
    "wp_get_attachment_url",
    "theme_mod_header_image",
    "theme_mod_background_image",
    "the_content",
    "upload_dir",
    "widget_text",
);

Those hooks also have their own filter hooks, so you can customize with other plugins you are using, etc.

add_filter('dynamic_hostname_filters' function($hooks){
    $hooks[] = 'some_filter_hook';
    return $hooks;
});
