我正在制作我的第一个仪表板小部件，它正在成功显示，但下面函数的输出HTML显示在仪表板页面上打开HTML标记之前。

涉及的代码如下。在add\\u action（）调用之前是否需要一些init调用？

function example_add_dashboard_widgets() {
    wp_add_dashboard_widget(
                 \'donationsmtcarmel\',         // Widget slug.
                 \'Mt. Carmel Donations\',         // Title.
                 \'draw_widget\' // Display function.
        );  
 }
add_action( \'wp_dashboard_setup\', \'draw_widget\' );


function draw_widget() {
    $dObj = new Donation;
    $donations = $dObj->retrieve("`paypal_txn` != \'\' AND `archived` = \'0\' ORDER BY `date` DESC");
    echo \'
      <div id="normal-sortables-20" class="meta-box-sortables ui-sortable"><div id="donations_postbox" class="postbox" style="margin-top:12px">
        <div class="handlediv" title="Click to toggle"><br></div><h3 class="hndle"><span style="padding-left:12px">Mt. Carmel Donations</span></h3>
          <div class="inside">
            <div class="table table_content" style="padding-left:12px">\';
     echo "<p><strong>Recent Donations:</strong></p><p style=\'padding-left:12px\'>";
     if ($donations) { 
        foreach ($donations as $d) {
            echo $d->donor_name.\'&nbsp;&nbsp;&nbsp;$\'.$d->tx()->mc_gross.\'&nbsp;&nbsp;&nbsp;\'.date(\'n/j/Y g:i A\', strtotime($d->date))."<br/>\\n";
        }
     } else {
         echo \'None.\';
     }

     echo \'   </p>
              <p><a href="http://www.foo.org/wp-admin/index.php?page=donations">Donations Page</a></p>
            </div>
         </div>
        </div>
       </div>
      \';

}
