php下拉选项的批量操作示例

这篇文章主要为大家详细介绍了php下拉选项的批量操作示例，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随php教程的小玲来看看吧！

实现功能，操作项可以单独删除，批量项可以批量删除，批量显示，隐藏（改广告的数据库的status_is的值）；

1.视图关键点：

代码如下:

<td ><input type="checkbox" name="id[]" value="<?php
/*   php教程 www.512Pic.com   */
 echo $row->id?>"> 
        <?php
/*   php教程 www.512Pic.com   */
 echo $row->id?></td> 

代码如下:

<div class="fixsel"> 
          <input type="checkbox" name="chkall" id="chkall" onclick="checkAll(this.form, 'id')" /> 
          <label for="chkall">全选</label> 
          <select name="command"> 
            <option>选择操作</option> 
            <option value="adDelete">删除</option> 
            <option value="adVerify">显示</option> 
            <option value="adUnVerify">隐藏</option> 
          </select> 
          <input id="submit_maskall" class="button confirmSubmit" type="submit" value="提交" name="maskall" /> 
        </div> 

代码如下:

/*单个删除*/

<a href="<?php
/*   php教程 www.512Pic.com   */
 echo  $this->createUrl('batch',array('command'=>'adDelete', 'id'=>$row->id))?>" class="confirmSubmit"> 

2.控制器：

代码如下:

/** 
     * 批量操作 
     * 
     */
    public function actionBatch () 
    { 
        if (XUtils::method() == 'GET') {     //单个删除是get方式 
            $command = trim($_GET['command']); 
            $ids = intval($_GET['id']); 
        } else 
            if (XUtils::method() == 'POST') { 
                $command = trim($_POST['command']); 
                $ids = $_POST['id']; 
                is_array($ids) && $ids = implode(',', $ids); 
            } else { 
                XUtils::message('errorBack', '只支持POST,GET数据'); 
            } 
        empty($ids) && XUtils::message('error', '未选择记录'); 

        switch ($command) { 

            case 'adDelete': 
                parent::_acl('ad_delete'); 
                parent::_adminiLogger(array('catalog'=>'delete', 'intro'=>'删除广告，ID:'.$ids)); 
                parent::_delete(new Ad(), $ids, array ('ad' ), array ('attach_file' )); 
                break; 
            case 'adVerify': 
                parent::_acl('ad_verify'); 
                parent::_adminiLogger(array('catalog'=>'delete', 'intro'=>'广告状态变更为显示，ID:'.$ids)); 
                parent::_verify(new Ad(), 'verify', $ids, array ('ad' )); 

                break; 
            case 'adUnVerify': 
                parent::_acl('ad_verify'); 
                parent::_adminiLogger(array('catalog'=>'delete', 'intro'=>'广告状态变更为隐藏，ID:'.$ids)); 
                parent::_verify(new Ad(), 'unVerify', $ids, array ('ad' )); 
                break; 
            default: 
                throw new CHttpException(404, '错误的操作类型:' . $command); 
                break; 
        } 

    } 

父类的删除函数：

代码如下:

protected function _delete ($model = null, $id = '', $redirect = 'index', $attach = null, $pkField = 'id') 
    { 
        if ($attach) {          //如果有附件要删除广告的图片 
            $data = $model->findAll($pkField . ' IN(:id)', array (':id' => $id )); 
            foreach ((array) $data as $row) { 
                foreach ((array) $attach as $value) { 
                    if (! empty($row[$value])) { 
                        @unlink($row[$value]); 
                    } 
                } 
            } 
        } 
        $result = $model->deleteAll(array ('condition' => 'id IN(' . $id . ')' )); 
        //刷新缓存 
        self::_refreshCache($model); 
        $this->redirect($redirect); 
    } 

代码如下:

protected function _verify ($model = null, $type = 'verify', $id = '', $redirect = 'index', $cdField = 'status_is', $pkField = 'id') 
    { 
        $criteria = new CDbCriteria(); 
        $criteria->condition = $pkField . ' IN(' . $id . ')'; 
        $showStatus = $type == 'verify' ? 'Y' : 'N'; 
        $result = $model->updateAll(array ($cdField => $showStatus ), $criteria); 
        //刷新缓存 
        self::_refreshCache($model); 
        $this->redirect($redirect); 
    }
