我需要帮助自动检测URL的标题。我将使用当前网站博客帖子的链接。
我现在拥有的代码：
<?php
$custom_fields = get_post_custom($post_id); //Current post id
$my_custom_field = $custom_fields[\'Featured-Blog\']; //key name
foreach ( $my_custom_field as $key => $url )
echo $key."<a href=\'" .$url. "\'>Title</a><br /><br /><br/>";
?>
我需要代码自动检测URL的标题，而不是“标题”。有人能帮忙吗？
我的职能。php代码：
$args = array(
\'labels\' =>$labels,
\'public\' =>true,
\'publicly_queryable\' =>true,
\'show_ui\' =>true,
\'query_var\' =>true,
\'menu_icon\' =>get_bloginfo(\'template_url\').\'/images/serviceicon.png\',
\'rewrite\' =>array(\'slug\' => \'Featured-Blog\'),
\'capability_type\' =>\'post\',
\'hierarchical\' =>true,
\'menu_position\' =>\'\',
\'supports\' =>array(\'title\',\'editor\',\'thumbnail\',\'custom-fields\',\'excerpt\' ),
\'has_archive\' =>true
);

如果你储存邮件，你的生活可能会更轻松IDs 作为您的自定义元值，而不是发布URLs; 也就是说，你可以试试back-tracing the Post ID using url_to_postid(), 然后从ID获取帖子对象，然后获取帖子标题：
// Your original code here
$custom_fields = get_post_custom($post_id); //Current post id
$my_custom_field = $custom_fields[\'Featured-Blog\']; //key name
// Your original foreach loop
foreach ( $my_custom_field as $key => $url ) {
// Fetch the Post ID from the url
$postid = url_to_postid( $url );
// Get the post object
$post_obj = get_post( $postid );
// Get the post title
$post_title = $post_obj->post_title;
// Then construct the link:
$link = \'<a href="\' . $url . \'">\' . $post_title . \'</a>\';
}
编辑法典条目中规定的
url_to_postid(), 对于自定义帖子类型，该函数当前无法正常工作。此行为预计将在WordPress 3.7中修复。
在此期间，最简单的选择是储存邮件IDs 而不是postURLs:
// Your original code here
$custom_fields = get_post_custom($post_id); //Current post id
$my_custom_field = $custom_fields[\'Featured-Blog\']; //key name
// Your original foreach loop
foreach ( $my_custom_field as $key => $id ) {
// Get the post object
$post_obj = get_post( $id );
// Get the post title
$post_title = $post_obj->post_title;
// Get the post permalink
$post_permalink = get_permalink( $id );
// Then construct the link:
$link = \'<a href="\' . $post_permalink . \'">\' . $post_title . \'</a>\';
}
