控制器里代码：（单行需要下标0）

$map['uid'] = is_login();

$teacher = D('Teacher')->where($map)->select();

        $this->assign('teacher', $teacher[0]);

$this->display();

视图代码：

<p class="Info_Name"><span>*</span>真实姓名：</p>

<div class="Info_Control Info_Control_Type2">

<input type="text" name="real_name" id="real_name" placeholder="请输入真实姓名" checkrule="" maxlength="10" min="2" value="{$teacher.real_name}">

 </div>
