drupal - 更改搜索表单操作不适用于自定义搜索模块，Drupal 6

Question

我正在更改 Drupal 站点上基本搜索表单的表单操作的值。这是我添加到我们的 hook_form_alter() 中的行在我们的自定义搜索模块中实现:

$form_id['#action'] = 'http://mydomain.com/search/customsearchmodule/';

当我查看表单的来源时，操作与我在上一行中设置的完全一样。问题是，提交表单后，显示的是默认搜索结果页面，而不是自定义搜索结果页面。

如何设置显示自定义搜索结果页面，而不是默认页面？

这是我的 hook_form_alter() 的示例执行:

/**
* Implementation of hook_form_alter()
*/
function mymodule_form_alter(&$form, &$form_state, $form_id) {
  if($form_id == 'search_block_form') {
    $form['#action'] = 'http://www.mydomain.com/search/mymodule/';
  }
}

另外:

我添加了 unset($form['#submit']);我对 hook_form_alter() 的实现并且，在提交表单后，到达了适当的 URL ( http://www.mydomain.com/search/mymodule)，只是没有传递任何数据(没有关键字)。

我正在研究 Drupal API 和核心搜索模块，只是想看看它是如何工作的。这是核心 search_box_form_submit()来自我们的 /modules/search/search.module的功能:

    /**
     * Process a block search form submission.
     */
    function search_box_form_submit($form, &$form_state) {
      // The search form relies on control of the redirect destination for its
      // functionality, so we override any static destination set in the request,
      // for example by drupal_access_denied() or drupal_not_found()
      // (see http://drupal.org/node/292565).
      if (isset($_REQUEST['destination'])) {
        unset($_REQUEST['destination']);
      }
      if (isset($_REQUEST['edit']['destination'])) {
        unset($_REQUEST['edit']['destination']);
      }

      $form_id = $form['form_id']['#value'];
      $form_state['redirect'] = 'search/node/'. trim($form_state['values'][$form_id]);
    }

请注意定义 $form_state['redirect'] 的行。如果我将此行注释掉，则搜索表单将位于 search/mymodule/页面，尽管没有传递任何搜索关键字。

编辑 - 工作代码

最终解决方案是 nmc 答案的修改版本。我不得不改变他的 mymodule_form_submit()执行。该函数应命名为 mymodule_submit()并且函数中的代码也需要更改:

function mymodule_submit($form, &$form_state) {
  // The search form relies on control of the redirect destination for its
  // functionality, so we override any static destination set in the request,
  // for example by drupal_access_denied() or drupal_not_found()
  // (see http://drupal.org/node/292565).
  if (isset($_GET['destination'])) {
    unset($_GET['destination']);
  }

  // Check to see if the form was submitted empty.
  // If it is empty, display an error message.
  // (This method is used instead of setting #required to TRUE for this field
  // because that results in a confusing error message.  It would say a plain
  // "field is required" because the search keywords field has no title.
  // The error message would also complain about a missing #title field.)
  if ($form_state['values']['search_block_form'] == '')
  {
    form_set_error('keys', t('Please enter some keywords.'));
  }
  else
  {
    $form_id = $form['form_id']['#value'];
    $form_state['redirect'] = 'search/mymodule/'. trim($form_state['values'][$form_id]);
  }
}

Answer 1

尝试更改表单调用的提交函数，而不是更改表单操作的 URL:

/**
* Implementation of hook_form_alter()
*/
function mymodule_form_alter(&$form, &$form_state, $form_id) {
  if($form_id == 'search_block_form') {
    $form['#submit'][] = 'mymodule_form_submit';
  }
}

/**
 * Process a block search form submission.
 */
function mymodule_form_submit($form, &$form_state) {
  // The search form relies on control of the redirect destination for its
  // functionality, so we override any static destination set in the request,
  // for example by drupal_access_denied() or drupal_not_found()
  // (see http://drupal.org/node/292565).
  if (isset($_GET['destination'])) {
    unset($_GET['destination']);
  }

  // Check to see if the form was submitted empty.
  // If it is empty, display an error message.
  // (This method is used instead of setting #required to TRUE for this field
  // because that results in a confusing error message.  It would say a plain
  // "field is required" because the search keywords field has no title.
  // The error message would also complain about a missing #title field.)
  if ($form_state['values']['search_block_form'] == '') {
    form_set_error('keys', t('Please enter some keywords.'));
  }

  $form_id = $form['form_id']['#value'];
  $form_state['redirect'] = 'search/mymodule/'. trim($form_state['values'][$form_id]);
  }
  else {
    form_set_error(NULL, t('Search is currently disabled.'), 'error');
  }
}

这应该将搜索重定向到 http://www.mydomain.com/search/mymodule/keywords然后您的模块可以相应地处理关键字。
