WordPress setup_postdata用法

setup_postdate函数可以设置全局$post变量，使得自定义查询文章语句后也可以使用the_permalink()、the_title()等来直接获取文章信息，具体使用方法如下：

<?php  global $wpdb, $post; //注意这里要申明$post    $str = "SELECT $wpdb->posts.* FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish'";  $result = $wpdb->get_results( $str );    if ( $result ) {  foreach ( $result as $post ): //如果这里获取的是$post_id，可以$post = get_post($post_id);  setup_postdata( $post );  ?>  <li><a href="<?php the_permalink()?>"><?php the_title();?></a></li>  <?php   endforeach;  }  ?>

<?php global $wpdb, $post; //注意这里要申明$post $str = "SELECT $wpdb->posts.* FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish'"; $result = $wpdb->get_results( $str ); if ( $result ) { foreach ( $result as $post ): //如果这里获取的是$post_id，可以$post = get_post($post_id); setup_postdata( $post ); ?> <li><a href="<?php the_permalink()?>"><?php the_title();?></a></li> <?php endforeach; } ?>
