我认为你可以使用WordPress钩子，这就是我的做法。在添加以下代码中：functions.php&nbsp;<?php&nbsp;&nbsp; &nbsp; &nbsp; function populate_posts_data( $posts, $query ) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;global $wpdb;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;if ( !count( $posts ) )&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;return $posts;&nbsp; // posts array is empty send it back with thanks.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;while ( $posts as $post ) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// do whatever you want for each post, alter its data, etc&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$post->title = $post->title . ' Edited');&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;return $posts;&nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp; &nbsp; &nbsp;add_filter( 'the_posts', 'populate_posts_data' );&nbsp;?>谢谢，希望它能帮助你。
