Question

我有一个带有authController的表单页面用于验证。以下是表单页面的代码：

<div class="main-content">
    <h3>log in as student</h3>
    <h3>
        <!-- SHOW URL MESSAGE HERE -->
    </h3>
    <form action="../app/controllers/authController.php" class="login_form" method="POST">
        <div class="form-group">
            <label for="username">Username</label>
            <input type="text" name="username" id="" class="input_field">
        </div>
        <div class="form-group">
            <label for="password">Password</label>
            <input type="password" name="password" id="" class="input_field">
        </div>
        <div class="form-group">
            <input type="submit" name="type" id="" value="Log In" class="btn btn-info">
        </div>
    </form>
</div>

以下是authController的代码：

if ($_POST['type'] == 'Log In') {

    if (! Validator::notEmpty()->validate($_POST['username']) || 
        ! Validator::notEmpty()->validate($_POST['password'])) {

        $err_msg = "One of the fields is empty";
        $user->redirect('stu_login.php?type=' . $err_msg);
        exit;
    }

如何在$err_msg所在的表单页面上显示authController中定义的？

Answer 1

替换

$user->redirect('stu_login.php?type=' . $err_msg);

要

$user->redirect('stu_login.php?msg=' . $err_msg);

并像stu_login.php一样使用

<h3>
    <!-- ERROR OR OTHER MESSAGE -->
    <?php 
        if(isset($_GET['msg'] != '') 
           echo $_GET['msg']; 
    ?> 
</h3>

在页面上显示url变量消息
