php – 将结果添加到WordPress搜索结果中

排除页面

排除搜索结果中的网页.可以通过仅显示帖子的结果来创建限制搜索结果的操作挂钩.

以下示例演示了如何执行此操作：

function search_filter($query) {
  if ( !is_admin() && $query->is_main_query() ) {
    if ($query->is_search) {
      $query->set('post_type','post');
    }
  }
}

add_action('pre_get_posts','search_filter');

在搜索结果中包含自定义帖子类型

function search_filter($query) {
  if ( !is_admin() && $query->is_main_query() ) {
    if ($query->is_search) {
      $query->set('post_type',array( 'post','movie' ) );
    }
  }
}

add_action('pre_get_posts','search_filter');

包括自定义/ API结果

function search_filter() {
    if ( is_search() ) {
        // Do your API call here
        // Save retrieved data in your wordpress
        // This will also help to you avoid api call for repeated queries.
        $post_id = wp_insert_post( $post,$wp_error ); // wp_insert_post() // Programatically insert queries result into your wordpress database
        array_push( $query->api,$post_id );
    }
}
add_action('pre_get_posts','search_filter');    
function have_posts_override(){
    if ( is_search() ) {
        global $wp_query;
        $api_post = $wp_query->api;
        foreach ($api_post as $key) {
        // This will enable you to add results you received using API call
        // into default search results.
            array_push($wp_query->posts,$key); 
        }
    }
}
add_action( 'found_posts','have_posts_override' );
