筛选结果的搜索挂钩？

Question

我一直在浏览文档和源代码，寻找的东西没有运气。

是否有一个Drupal 6钩子在hook_search（）之后被调用，但在$ results被传递给模板系统之前被调用？

我需要做一个相当自定义的修剪和重新排序结果返回。我可以重新实现hook_search（），但这似乎是矫枉过正。

谢谢。

没有; search_view()（它显示结果）调用search_data()，调用hook_search()然后立即主题化结果。重新实施hook_search()可能是最直接的路线。

这样说，你可以改为hook_menu_alter()并让搜索页面调用你的自定义函数，而不是调用search_view()（随后调用search_data()）。例如：

function test_menu_alter(&$items) { 
    $items['search']['page callback'] = 'test_search_view'; 

    foreach (module_implements('search') as $name) { 
    $items['search/' . $name . '/%menu_tail']['page callback'] = 'test_search_view'; 
    } 
} 

// Note: identical to search_view except for --- CHANGED --- 
function test_search_view($type = 'node') { 
    // Search form submits with POST but redirects to GET. This way we can keep 
    // the search query URL clean as a whistle: 
    // search/type/keyword+keyword 
    if (!isset($_POST['form_id'])) { 
    if ($type == '') { 
     // Note: search/node can not be a default tab because it would take on the 
     // path of its parent (search). It would prevent remembering keywords when 
     // switching tabs. This is why we drupal_goto to it from the parent instead. 
     drupal_goto('search/node'); 
    } 

    $keys = search_get_keys(); 
    // Only perform search if there is non-whitespace search term: 
    $results = ''; 
    if (trim($keys)) { 
     // Log the search keys: 
     watchdog('search', '%keys (@type).', array('%keys' => $keys, '@type' => module_invoke($type, 'search', 'name')), WATCHDOG_NOTICE, l(t('results'), 'search/'. $type .'/'. $keys)); 

     // Collect the search results: 
     // --- CHANGED --- 
     // $results = search_data($keys, $type); 
     // Instead of using search_data, use our own function 
     $results = test_search_data($keys, $type); 
     // --- END CHANGED --- 

     if ($results) { 
     $results = theme('box', t('Search results'), $results); 
     } 
     else { 
     $results = theme('box', t('Your search yielded no results'), search_help('search#noresults', drupal_help_arg())); 
     } 
    } 

    // Construct the search form. 
    $output = drupal_get_form('search_form', NULL, $keys, $type); 
    $output .= $results; 

    return $output; 
    } 

    return drupal_get_form('search_form', NULL, empty($keys) ? '' : $keys, $type); 
} 

// Note: identical to search_data() except for --- CHANGED --- 
function test_search_data($keys = NULL, $type = 'node') { 

    if (isset($keys)) { 
    if (module_hook($type, 'search')) { 
     $results = module_invoke($type, 'search', 'search', $keys); 
     if (isset($results) && is_array($results) && count($results)) { 
     // --- CHANGED --- 
     // This dsm() is called immediately after hook_search() but before 
     // the results get themed. Put your code here. 
     dsm($results); 
     // --- END CHANGED --- 

     if (module_hook($type, 'search_page')) { 
      return module_invoke($type, 'search_page', $results); 
     } 
     else { 
      return theme('search_results', $results, $type); 
     } 
     } 
    } 
    } 
}

您可以使用hook_search_page()重新排序或格式化搜索结果。

钩子search_execute允许你以你需要的方式修改查询。你甚至可以触发与自定义的SQL新的查询，例如：

function mymodule_search_execute($keys = NULL, $conditions = NULL) { 

     // Do some query here. 
     $result = my_fancy_query(); 

     // Results in a Drupal themed way for search. 
     $results[] = array(
     'link' => (string) $result->U, 
     'title' => $title, 
     'snippet' => $snippet, 
     'keys' => check_plain($keys), 
     'extra' => array($extra), 
     'date' => NULL, 
    );
