thinkphp批量删除的实现

html:

<li>
　　<a class="delete" href="__URL__/deleteSelected/navTabId/__MODULE__" target="selectedTodo"  posttype="string" calback="navTabAjaxMenu" rel='ids' title="你确定要删除吗？" warn="请选择节点"><span>批量删除</span></a>
</li>

<table class="table" width="100%" layoutH="138">
        <thead>
            <tr>
                <th width="10"><input type="checkbox" class="checkboxCtrl" group="ids" /></th>
                <th width="60">编号</th>
            </tr>
        </thead>
        <tbody>
        <volist id="vo" name="list">
            <tr>
                <td><input name="ids" type="checkbox" value="{$vo.id}"> </td>
                <td>{$vo['id']}</td>
            </tr>
        </volist>
</table>

 php:

public function deleteSelected() {
        //删除指定记录
        $name = $this->getActionName();
        $model = D($name);
        if (!empty($model)) {
            $pk = $model->getPk();
            $ids = $_REQUEST['ids'];
            if (!empty($ids)) {
                $condition = array($pk => array('in', explode(',', $ids)));
                if (false !== $model->where($condition)->delete()) {
                    $sql =  $model->_sql();
                    $this->success("删除成功！");
                } else {
                    $this->error('删除失败！');
                }
            } else {
                $this->error('非法操作');
            }
        }

 原理是根据Web表单提交时可以传递数组，例如：

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">

<input type="text" name="tree[tree1][fruit]">
<input type="text" name="tree[tree1][height]">

<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">

<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">

则传递过来的是：

$_POST[] = array(
    'firstname'=>'value',
    'lastname'=>'value',
    'email'=>'value',
    'address'=>'value',
    'tree' => array(
        'tree1'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree2'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree3'=>array(
            'fruit'=>'value',
            'height'=>'value'
        )
    )
)
