ThinkPHP 3.0的parseFieldsMap问题
数据库里的字段是uid, uname
页面表单的name分别是id和name

Model代码:

PHP code

-->
    protected $_map = array(
        'id' => 'uid',
        'name' => 'uname',
    );

Copy after login


Action代码:
PHP code
<!--

-->
        $model = M('Demo');
        $list = $model -> select();
        print_r($list);
        $list = $model -> parseFieldsMap($list);
        echo '<br><br>';
        print_r($list);

Copy after login


输出结果都一样
都是

Array ( [0] => Array ( [uid] => 1 [uname] => 测试 ) ) 


问题在这里:
按官方的说法是parseFieldsMap转了以后
最终输出的那个$list应该是

Array ( [0] => Array ( [id] => 1 [name] => 测试 ) ) 

才对啊?
网上到处搜不到
哪位知道还请不吝赐教啊!

------解决方案--------------------
其实 你应该区分 M 和 D 方法的 M的方法是不加载自己定义的模型文件, 而$_map 是定义在你自己创建的模型文件中, 所以应该这样调用: $list = D('Demo') -> parseFieldsMap($list);
------解决方案--------------------
由 parseFieldsMap 方法的定义可知:
他只能作用于一维数组,即
Array ( [uid] => 1 [uname] => 测试 )
变为
Array ( [id] => 1 [name] => 测试 )
