Wordpress：自定义元标记列表

Question

Using Wordpress, I am trying to write a php script that, given a certain post ID, returns all the related custom tags (also named custom terms, i. e. these words that I can use to meta describe a post and are category-independent. For example, in this page the custom terms are "passabile" and "thriller").

Is there a way to do that, possibly some WP-method that takes care of custom tag revisions?

Thanks a lot

Answer 1

Use the get_post_meta() function. Say your tag is named 'custom_terms', you can do this:

$terms = get_post_meta( $id, 'custom_terms' );

If you are already on the post that you want to get that information for you can do:

$terms = get_post_meta( get_the_ID(), 'custom_terms' );

See here: http://codex.wordpress.org/Function_Reference/get_post_meta

$terms will be an array containing all of the values.

EDIT: If you are talking strictly about the tags of a post, you can try this:

$tags = get_the_tags();

This returns an array of tag objects that you can access by looping through them.
