wordpress列表分页显示404页面的解决办法
今天客户wordpress网站出现列表分页显示404页面的情况,列表页正常,翻页的时候出现404的错误页面。
遇到这个问题需要修改wordpress文件wp-includesclass-wp.php ,
要找到对应函数function handle_404()
public function handle_404() { global $wp_query; /** * Filters whether to short-circuit default header status handling. * * Returning a non-false value from the filter will short-circuit the handling * and return early. * * @since 4.5.0 * * @param bool $preempt Whether to short-circuit default header status handling. Default false. * @param WP_Query $wp_query WordPress Query object. */ if ( false !== apply_filters( 'pre_handle_404', false, $wp_query ) ) { return; } // If we've already issued a 404, bail. if ( is_404() ) return; // Never 404 for the admin, robots, or if we found posts. if ( is_admin() || is_robots() || $wp_query->posts ) { $success = true; if ( is_singular() ) { $p = false; if ( $wp_query->post instanceof WP_Post ) { $p = clone $wp_query->post; } // Only set X-Pingback for single posts that allow pings. if ( $p && pings_open( $p ) ) { @header( 'X-Pingback: ' . get_bloginfo( 'pingback_url', 'display' ) ); } // check for paged content that exceeds the max number of pages $next = '<!--nextpage-->'; if ( $p && false !== strpos( $p->post_content, $next ) && ! empty( $this->query_vars['page'] ) ) { $page = trim( $this->query_vars['page'], '/' ); $success = (int) $page <= ( substr_count( $p->post_content, $next ) + 1 ); } } if ( $success ) { status_header( 200 ); return; } } // We will 404 for paged queries, as no posts were found. if ( ! is_paged() ) { // Don't 404 for authors without posts as long as they matched an author on this site. $author = get_query_var( 'author' ); if ( is_author() && is_numeric( $author ) && $author > 0 && is_user_member_of_blog( $author ) ) { status_header( 200 ); return; } // Don't 404 for these queries if they matched an object. if ( ( is_tag() || is_category() || is_tax() || is_post_type_archive() ) && get_queried_object() ) { status_header( 200 ); return; } // Don't 404 for these queries either. if ( is_home() || is_search() || is_feed() ) { status_header( 200 ); return; } } // Guess it's time to 404. $wp_query->set_404(); status_header( 404 ); nocache_headers(); }
修改为如下代码,就可以解决这个问题。
function handle_404() { global $wp_query; if ( !is_admin() && ( 0 == count( $wp_query->posts ) ) && !is_404() && !is_robots() && !is_search() && !is_home() ) { // Don’t 404 for these queries if they matched an object. if ( ( is_tag() || is_category() || is_tax() || is_author() ) && $wp_query->get_queried_object() ) { if ( !is_404() ) status_header( 200 ); return; } $wp_query->set_404(); status_header( 404 ); nocache_headers(); } elseif ( !is_404() ) { status_header( 200 ); } }
