Wrong method signature: get_post_meta

[luis.ferro]

On wp-includes/post.php, around line 1458, there is the following signature of a method:

function get_post_meta($post_id, $key, $single = false)

This is incorrect and should be:

function get_post_meta($post_id, $key = null, $single = false)

Cheers,

p.s.- the only effect of this is a warning on the IDE that you can use and naturally a possibility of some warnings on PHP, if they are not squelched.

$key is always required, there should be no default value.

$key is always required, there should be no default value.

Actually the underlying meta API allows it to be skipped to return all meta for a post object.

There's a duplicate ticket though: #17013
