Yii CGridView自定义页脚

Question

我正在使用CGridView以网格格式显示数据，但是我无法创建自定义的页脚， 以下是我使用的代码：

<?php
      $this->widget('zii.widgets.grid.CGridView',
           array('dataProvider' => $dataProvider,
           'columns' => array(
               array(
                   'name' => 'created_date',
                   'header' => 'Created',
               ),
               array(
                   'name' => 'access_date',
                   'header' => 'Accessed',
               ),
               array(
                   'name' => 'referenceCode',
                   'header' => 'Ref Code',
               ),
               array(
                   'name' => 'designation',
                   'header' => 'Designation',
               ),                  
               array(
                   'name' => 'company',
                   'header' => 'Company',
               ),
               array(
                        'name' => 'recommended_actions',
                        'header' => 'Recommended Action',
                        'type' => 'html',
                        'value' => function($jobBoard) {
                            return CHtml::link($recAction[0]['display_text'], Yii::app()->createUrl($actionUrl, $params));
                        }
                    ),
               array(
                   'class' => 'CDataColumn',
                   'header' => 'List of Actions',
                   'type' => 'html',
                   'value' => function($jobBoard){
                        echo '<div class="action-joborder">
                                <ul class="moveto-joborder">
                                    <li>Action <img height="6" width="7" alt="" src="images/bg_action.gif">
                                    <ul>';
                                      echo '<li>'.CHtml::link($actionArray['display_text'], Yii::app()->createUrl($actionUrl, $params)).'</li>';                
                              echo '</ul>
                                </li>
                                </ul>
                               </div>';                        
                   },
                   'name' => 'actions',                    
               ),
    )));         
?>

上面的代码提供了带有分页器的页脚，我想放置一些按钮元素来控制网格。 网格应该如下所示， 是否有办法在页脚处创建自定义元素？

您可以扩展framework/zii/widgets/grid/CGridView.php并将其用于您的代码中。请扩展以下方法以更改页脚。

public function renderTableFooter()
{
  $hasFilter=$this->filter!==null && $this->filterPosition===self::FILTER_POS_FOOTER;
  $hasFooter=$this->getHasFooter();
  if($hasFilter || $hasFooter)
  {
    echo "<tfoot>\n";
    if($hasFooter)
    {
      echo "<tr>\n";
      foreach($this->columns as $column)
              $column->renderFooterCell();
      echo "</tr>\n";
    }
    if($hasFilter)
      $this->renderFilter();
    echo "</tfoot>\n";
  }
}

protected/components/GridView.php

Yii::import('zii.widgets.grid.CGridView');


class GridView extends CGridView
{

/**
 * Renders the table footer.
 */
public function renderTableFooter()
{
    $hasFilter=$this->filter!==null && $this->filterPosition===self::FILTER_POS_FOOTER;
    $hasFooter=$this->getHasFooter();
    if($hasFilter || $hasFooter)
    {
        echo "<tfoot>\n";
        if($hasFooter)
        {
            echo "<tr>\n";
            foreach($this->columns as $column){
                if($column->footer!='')
                    $column->footer=eval("return " . $column->footer.";");

                $column->renderFooterCell();
            }
            echo "</tr>\n";
        }
        if($hasFilter)
            $this->renderFilter();
        echo "</tfoot>\n";
    }
}

public function sumTotal($attribute){
    $data=$this->dataProvider->getData();

    $sum=0;
    foreach($data as $index => $value ){

        if(isset($data[$index]->{$attribute}))
            $sum+=$data[$index]->{$attribute};
    }

    return $sum;
}
