hook_block_view不传递信息

Question

我想在Drupal 7中构建我的第一个自定义模块。它是用户搜索数据库表的客户信息的块表单。我已经创建了模块和信息文件。我的模块显示在模块和块的下面，但是当我将该块添加到内容时，主题和内容不会从我的hook_block_view传递。所以，而不是显示的形式，它只显示块的标题和正文。有人能告诉我我错过了什么吗？

<?php 
/** 
*@file 
* 
*/ 

/** Implements hook_block_info(). 
* 
*/ 

function searchEngine_block_info(){ 
    $blocks = array(); 

    $blocks['searchEngine_form'] = array (
     'info' => t("Applicant Search"), 
     'cache' => DRUPAL_CACHE_GLOBAL, 
    ); 
    return $blocks; 
} 

/** Implements hook_block_view(). 
* 
*/ 

function searchEngine_block_view($delta = ''){ 
    $block = array(); 
    switch($delta) { 
     case 'searchEngine_form': 
     $block['subject'] = t('Applicant Search'); 
     $block['content'] = drupal_get_form('searchEngine_form'); 
    break; 
    } 
    return $block; 
} 

function searchEngine_form($form, &$form_state) { 
    $form['searchOptions'] = array(
     '#type'  => 'select', 
     '#title' => t("Select how you would like to search for an applicant."), 
     '#default_value'=> variable_get("gwf", true), 
     '#options' => array(
      'gwf'  => "GWF".t(" Number"), 
      'email'  => t("Email"), 
      'name'  => t("Name"), 
      'phone_number' => t("Phone Number"), 
     ), 

    ); 
    $form['data'] = array(
     '#type'  => 'textfeild', 
     '#required' => TRUE, 
    ); 
    $form['submit'] = array(
       '#type' => 'submit', 
       '#value' => t('Submit'), 
     ); 
     return $form; 
} 

function searchEngine_submit($form, $form_state) { 
    if(isset($form['data'])){ 
     if($form['searchOptions'] == "name"){ 
      $name = preg_split("/[\s,]+/", $form['data']); 
      $result = db_query('SELECT * FROM tls_active_applicants WHERE first_name = '.$name['0'].' AND last_name = '.$name['1']); 
     }else{ 
      $result = db_query('SELECT * FROM tls_active_applicants WHERE '.$form['searchOptions'].' = '.$form['data']); 
     } 
     print_r($result); 
    } 
}

路过此处的一个可呈现阵列是好的：

$block['content'] = drupal_get_form('searchEngine_form'); 

我只是测试你的代码，形式似乎对我罚款：

现在我们知道了代码的作品，它让我怀疑这只是一些CSS或隐藏它的东西？

我也会安装devel模块，因为它有助于调试。

的，你可以使用此代码：

function searchEngine_block_view($delta = ''){ 
    $block = array(); 
    switch($delta) { 
     case 'searchEngine_form': 
     $block['subject'] = t('Applicant Search'); 
     $form = drupal_get_form('test_form'); 
     dpm($form); // call to dpm here to log if you are successfully getting the form at this point 
     $block['content'] = $form; 
    break; 
    } 
    return $block; 
}
