Question

所以我试着在drupal 8中实现一个主题，我想从搜索表单中删除搜索按钮。但当我尝试使用hook_form_alter时，我的.theme文件中没有任何内容被触及，我无法想到一个原因，据我所知，我的语法是正确的。即使它不正确，'die'和var_dump语句至少应输出一些东西，但目前不是。

我已将默认主题更改为drupal8_zymphonies_theme，并且挂钩已参与该主题，因此我认为必须有某种需要改变的设置。据说zymphonies主题是在这个结构/主题/ drupa8_zymphonies_theme，而我的endymion主题是主题/自定义/ endymion。不确定这是否重要，但我会提到它。

/**
 * @file
 * Contains theme override functions and preprocess functions
 */
var_dump('another hello');
die('hello there');
use Drupal\Core\Template\RenderWrapper;
use Drupal\search\Form\SearchBlockForm;
use Drupal\Core\Form\FormStateInterface;

    function endymion_form_search_block_form_alter(SearchBlockForm &$form, FormStateInterface &$form_state, $form_id) {
  //Remove the search box from the form to make the look a little cleaner
  $logger = \Drupal::logger('endymion');
  $logger->debug(''. print_R($form, true) . 'search form');
  if ($form_id == 'search_block_form') {
    $logger->debug(''. print_R($form, true) . 'search form');
    $form['actions']['#attributes']['class'][] = 'element-invisible';

    $form['search_block_form']['#size'] = 40;  // define size of the textfield
    $form['search_block_form']['#default_value'] = t('Search'); // Set a default value for the textfield

    // Add extra attributes to the text box
    $form['search_block_form']['#attributes']['onblur'] = "if (this.value == '') {this.value = 'Search';}";
    $form['search_block_form']['#attributes']['onfocus'] = "if (this.value == 'Search') {this.value = '';}";
    // Prevent user from searching the default text
    $form['#attributes']['onsubmit'] = "if(this.search_block_form.value=='Search'){ alert('Please enter a search'); return false; }";

    // Alternative (HTML5) placeholder attribute instead of using the javascript
    $form['search_block_form']['#attributes']['placeholder'] = t('Search');
  }
}

所有挂钩都未达到.theme文件并且未实现预处理
