我如何才能 select 只有 drupal 看门狗数据库 table 中变量的类型？

Question

*****~PLZ HELP~***我想对变量进行特殊化并采用类型，例如 'Notice'、'Error'..在接下来的代码中执行类似这样的操作

3710 a:6:{s:5:"%type";s:6:"Notice";s:8:"!message";s:24:"Undefined variable: path" ;s:9:"%function";s:3:"l()";s:5:"%file";s:44:"c";s:5:"%line";i: 2469;s:14:"severity_level";i:5;}

3711 a:6:{s:5:"%type";s:6:"Notice";s:8:"!message";s:24:"Undefined variable: path" ;s:9:"%function";s:3:"l()";s:5:"%file";s:44:"/c";s:5:"%line";i:2511 ;s:14:"severity_level";i:5;}

3712 a:6:{s:5:"%type";s:7:"Warning";s:8:"!message";s:141:"Missing argument 2 for l(), called in on line 171 and defined" ;s:9:"%function";s:3:"l()";s:5:"%file";s:44:"";s:5:"%line";i:2458;s :14:"severity_level";我:4;}

3713 a:6:{s:5:"%type";s:6:"Notice";s:8:"!message";s:24:"Undefined variable: path" ;s:9:"%function";s:3:"l()";s:5:"%file";s:44:"";s:5:"%line";i:2469;s :14:"severity_level";我:5;}**

    function blabla_page() {

          // Begin building

 the query.
      $query = db_select('watchdog', 'th')
        ->extend('PagerDefault')
        ->orderBy('wid')
        ->fields('th')
        ->limit(10);

    // Fetch the result set.
    $result = $query->execute();

      // Loop through each item and add to the $rows array.
      foreach ($result as $row) {
        $rows[] = array(
        $row -> wid,
        $row -> variables,
       );
      }
    // Headers for theme_table().
      $header = array('ID', 'Message');

    // Format output.
      $output = theme('table', array('header' => $header, 'rows' => $rows)). theme('pager');
         return $output;
       }

字段中的信息已序列化，应该这样做。

  foreach ($result as $row) {
    $message1=unserialize($row->variables);
    if($message1['%type']){
      $rows[] = array(
      $row -> wid,
      $message1['%type'],
    );
   }
  }

现在，只有当 %type 项存在时，输出才会添加到行数组中
