Drupal Views2暴露形式如何更改 [英] Drupal Views2 Exposed Form how to change

问题描述

我有一个暴露形式的视图。我正在尝试一些事情。理想情况下，我想下载一个没有按钮的表单。如果这是不可能的，那么我想让按钮文本与应用不同。

我现在被黑客攻击，并在views.module中更改views_form，但是不好像是正确的做法。我现在只有一个暴露的表格，但是如果我添加更多？

请参阅 http://www.wiredvillage.ca/News 为我的例子。

我在drupal.org上看到，看到其他同样的问题，但迄今为止没有解决方案。不知道得到Drupal帮助的最佳位置。

以下是迄今为止所做的更改：

  function views_exposed_form（& $ form_state）{
 //确保我们验证，因为此表单可能每页多次提交
 //。 
 $ form_state ['must_validate'] = TRUE; 
 $ view =& $ form_state ['view']; 
 $ display =& $ form_state ['display']; 
 $ form_state ['input'] = $ view-> get_exposed_input（）; 
 //让表单插件知道这是暴露的小部件。 
 $ form_state ['exposed'] = TRUE; 
 $ form ['＃info'] = array（）; 
 if（！variable_get（'clean_url'，FALSE））{
 $ form ['q'] = array（
'#type'=>'hidden'，
 '#value'=> $ view-> get_url（），
）; 
} 
 //遍历每个过滤器，让它生成其信息。 
 foreach（$ view-> filter as $ id => $ filter）{
 $ view-> filter [$ id]  - > exposed_form（$ form，$ form_state）; 
 if（$ info = $ view-> filter [$ id]  - > exposed_info（））{
 $ form ['＃info'] ['filter-' $ id] = $ info; 
} 
} 
 
 //我更改了此提交按钮的值GO 
 
 
 $ form ['submit'] =数组（
'#name'=>''，//阻止在$ _GET中显示
'#type'=>'submit'，
'#value'= > t（'go'），
）; 
 $ form ['＃action'] = url（$ view-> get_url（））; 
 $ form ['＃theme'] = views_theme_functions（'views_exposed_form'，$ view，$ display）; 
 $ form ['＃id'] = views_css_safe（'views_exposed_form-'。check_plain（$ view-> name）。' - '。check_plain（$ display-> id））; 
 // $ form ['＃attributes'] ['class'] = array（'views-exposed-form'）; 
 //如果使用AJAX，我们需要表单插件。 
 if（$ view-> use_ajax）{
 drupal_add_js（'misc / jquery.form.js'）; 
} 
 views_add_js（'dependent'）; 
 return $ form; 
} 
  

解决方案

根据伊顿的建议，我可以使用JavaScript而不是黑客模块。

基本上，您可以按照伊顿的建议修改hook_form_alter的文本，然后在相同的hook_form_alter，将您的自定义JS添加到drupal_add_js的一个调用，该JS隐藏了该按钮，并将该表单提交给选择下拉列表的onChange处理程序。你想要那个提交按钮那里的那些10％的JS失败的用户。

I have a View with an exposed form . I am trying to a few things on it. Ideally I would like to have a dropdown that fires the form with no button. If that is not possible then I would like to have the button text something different than apply.

I hacked it for now and change views_form in views.module but that does not seem like the right way to do it. I only have one exposed form right now, but what if I add more?

Please see http://www.wiredvillage.ca/News for my example.

I am poking around drupal.org and seeing others with the same problem but no solutions so far. Not sure where the best place to get Drupal help is.

Here is the change I made so far:

function views_exposed_form(&$form_state) {
  // Make sure that we validate because this form might be submitted
  // multiple times per page.
  $form_state['must_validate'] = TRUE;
  $view = &$form_state['view'];
  $display = &$form_state['display'];
  $form_state['input'] = $view->get_exposed_input();
  // Let form plugins know this is for exposed widgets.
  $form_state['exposed'] = TRUE;
  $form['#info'] = array();
  if (!variable_get('clean_url', FALSE)) {
    $form['q'] = array(
      '#type' => 'hidden',
      '#value' => $view->get_url(),
    );
  }
  // Go through each filter and let it generate its info.
  foreach ($view->filter as $id => $filter) {
    $view->filter[$id]->exposed_form($form, $form_state);
    if ($info = $view->filter[$id]->exposed_info()) {
      $form['#info']['filter-' . $id] = $info;
    }
  }

  // I CHANGED The VALUE OF THIS SUBMIT BUTTON TO GO


  $form['submit'] = array(
    '#name' => '', // prevent from showing up in $_GET.
    '#type' => 'submit',
    '#value' => t('go'),
  );
  $form['#action'] = url($view->get_url());
  $form['#theme'] = views_theme_functions('views_exposed_form', $view, $display);
  $form['#id'] = views_css_safe('views_exposed_form-' . check_plain($view->name) . '-' . check_plain($display->id));
//  $form['#attributes']['class'] = array('views-exposed-form');
  // If using AJAX, we need the form plugin.
  if ($view->use_ajax) {
    drupal_add_js('misc/jquery.form.js');
  }
  views_add_js('dependent');
  return $form;
}

解决方案

If you want the drop-down to fire, I'd use JavaScript instead of hacking the module as Eaton suggests.

Basically, you can modify the text with hook_form_alter as Eaton suggests, then use in the same hook_form_alter, add a call to drupal_add_js with your custom JS which hides the button and submits the form on the onChange handler of the select drop-down. You want that submit button there for those 10% of users for whom the JS fails.
