atom_enclosure()
Display the atom enclosure for the current post.
描述
Uses the global $post to check whether the post requires a password and if the user has the password for the post. If not then it will return before displaying.
Also uses the function get_post_custom() to get the post’s ‘enclosure’ metadata field and parses the value to display the enclosure(s). The enclosure(s) consist of link HTML tag(s) with a URI and other attributes.
源代码
File: wp-includes/feed.php
function atom_enclosure() {
if ( post_password_required() )
return;
foreach ( (array) get_post_custom() as $key => $val ) {
if ($key == 'enclosure') {
foreach ( (array) $val as $enc ) {
$enclosure = explode("\n", $enc);
/**
* Filters the atom enclosure HTML link tag for the current post.
*
* @since 2.2.0
*
* @param string $html_link_tag The HTML link tag with a URI and other attributes.
*/
echo apply_filters( 'atom_enclosure', '<link href="' . trim( htmlspecialchars( $enclosure[0] ) ) . '" rel="enclosure" length="' . trim( $enclosure[1] ) . '" type="' . trim( $enclosure[2] ) . '" />' . "\n" );
}
}
}
}
