get_category_by_path() WordPress Function
The get_category_by_path() function in WordPress allows you to get a category object by its path.
get_category_by_path( string $category_path, bool $full_match = true, string $output = OBJECT ) #
Retrieves a category based on URL containing the category slug.
Description
Breaks the $category_path parameter up to get the category slug.
Tries to find the child path and will return it. If it doesn’t find a match, then it will return the first category matching slug, if $full_match, is set to false. If it does not, then it will return null.
It is also possible that it will return a WP_Error object on failure. Check for it when using this function.
Parameters
- $category_path
(string)(Required)URL containing category slugs.
- $full_match
(bool)(Optional) Whether full path should be matched.
Default value: true
- $output
(string)(Optional) The required return type. One of OBJECT, ARRAY_A, or ARRAY_N, which correspond to a WP_Term object, an associative array, or a numeric array, respectively.
Default value: OBJECT
Return
(WP_Term|array|WP_Error|null) Type is based on $output value.
