At Pressable, the WordPress Core files are symbolically linked to another location on the platform. In other words, they are not in the site root, as is the case with a standard WordPress install. Due to this, using
ABSPATH to locate files in the site can result in errors.
ABSPATH vs. WP_CONTENT_DIR
ABSPATH can be used when pointing to Core files, but it will not function correctly if used to locate files/folders within
For example, the following on Pressable:
$target_path = ABSPATH . 'wp-content/plugins/order-tracking/order-sheets/';
$target_path = WP_CONTENT_DIR . '/plugins/order-tracking/order-sheets/';
WP_CONTENT_DIR, files/folders in the site root can be successfully accessed. Note that
ABSPATH has a trailing slash, whereas
WP_CONTENT_DIR does not.
Create Your Own Constant
If you are trying to access the site root on Pressable in various parts of your code and you’d also prefer for the implementation to be less brittle and readily modifidable, we’d recommend the use of a PHP constant to define the site root:
define('PRESSABLE_SITE_ROOT', str_replace( 'wp-content', '', WP_CONTENT_DIR));
This would define
/srv/htdocs/, and it should also be usable on other hosting platforms:
$target_path = PRESSABLE_SITE_ROOT . 'wp-content/plugins/order-tracking/order-sheets/';
This constant could be placed in a plugin or a theme. It is not recommended to use this constant in
wp-config.php because some hosting platforms often do not migrate
wp-config.php or allow it to be modified.
Paths in WP-Admin
While not preferable, if a plugin ever requires you to set an option for your site root via wp-admin, you should use the following path:
