I have a custom field “site_link” which is of the type “Link to page or article”.
I want to display this url in my RSS feed.
I use the function in “function fields_in_feed” in function.php
If I use:. get_field($post_id, “site_link”, true ) > it does not show me anything
If I use: . get_post_meta($post_id, “site_link”, true) > it shows me a number but not a URL
Do you have a solution
Reminder of the base code “function fields_in_feed”:
function fields_in_feed ($ content) {
if (is_feed ()) {
$ post_id = get_the_ID ();
$ output = ”;
$ output. = ”. get_post_meta ($post_id, “field”, true). </ P> ‘;
$ output. = ‘</ div>’;
$ content = $ content. $ output;
}
return $ content;
}
add_filter ( ‘the_content’, ‘fields_in_feed’);
get_field('site_link', $post_id);
The first argument for get field is the field name, second is the post ID, this is reverse of get_post_meta()
