get_post_custom()WP 1.2.0

Retrieve post meta fields, based on post ID.

The post meta fields are retrieved from the cache where possible, so the function is optimized to be called more than once.

No Hooks.

Return

Mixed. An array of values. False for an invalid $post_id (non-numeric, zero, or negative value). An empty string if a valid but non-existing post ID is passed.

Usage

get_post_custom( $post_id );
$post_id(int)
Post ID.
Default: ID of the global $post

Examples

#1 Get the same post meta-fields with different values

Get the values of custom fields with the key my_custom_field for post 72 (assuming that the post has 3 such fields with the values "dogs", "47" and "selfies")

$custom_fields = get_post_custom( 72 );
$my_custom_field = $custom_fields['my_custom_field'];

foreach ( $my_custom_field as $key => $value ){
	echo $key . " => " . $value . "<br />";
}

As a result, we will see the following on the screen:

0 => dogs
1 => 47
2 => selfies
