Retrieves post data given a post ID or post object.
See sanitize_post() for optional $filter values. Also, the parameter
`$post`, must be given as a variable, since it is passed by reference.
function get_post( $post = null, $output = OBJECT, $filter = 'raw' ) {
if ( empty( $post ) && isset( $GLOBALS['post'] ) ) {
$post = $GLOBALS['post'];
}
if ( $post instanceof WP_Post ) {
$_post = $post;
} elseif ( is_object( $post ) ) {
if ( empty( $post->filter ) ) {
$_post = sanitize_post( $post, 'raw' );
$_post = new WP_Post( $_post );
} elseif ( 'raw' === $post->filter ) {
$_post = new WP_Post( $post );
} else {
$_post = WP_Post::get_instance( $post->ID );
}
} else {
$_post = WP_Post::get_instance( $post );
}
if ( ! $_post ) {
return null;
}
$_post = $_post->filter( $filter );
if ( ARRAY_A === $output ) {
return $_post->to_array();
} elseif ( ARRAY_N === $output ) {
return array_values( $_post->to_array() );
}
return $_post;
