​​黄聪：wordpress通过page的ID或者别名获取内容​​

知道ID：

$page_id = 123; 
$page_data = get_page( $page_id ); 
echo '<h3>'. $page_data->post_title .'</h3>';// 标题
echo apply_filters('the_content', $page_data->post_content);  //内容

知道别名：

$name = 'about'; //page别名
global $wpdb;
$page_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = '$name'");
echo $page_data = get_page( $page_id )->post_content;
