Question

我正在使用Bootstrap 4，我创建了一个双窗格表单;注册和登录表格。

我知道使用AJAX更适合这种情况，它不会使页面刷新，但是，我问是否有任何方法可以实现页面刷新并仅使用PHP预览同一个窗格。 / p>

在代码中使用PHP。有什么办法，当我在注册窗格（右侧的那个）中提交表单时，页面会刷新并保持在同一个窗格中。

<!-- Tabs -->
        <nav class="register-nav">
            <div class="nav nav-tabs nav-justified" id="nav-tab" role="tablist">
                <a class="nav-item nav-link active" id="nav-signin-tab" data-toggle="tab" href="#nav-signin" role="tab">Sign in</a>
                <a class="nav-item nav-link" id="nav-signup-tab" data-toggle="tab" href="#nav-signup" role="tab">Create New Account</a>
            </div>
        </nav>
        <!-- Content of Tabs -->
        <div class="tab-content" id="nav-tabContent">
            <!-- Sign in Tab Pane -->
            <div class="tab-pane fade show active" id="nav-signin" role="tabpanel">

Answer 1

它实际上不是PHP的东西，但您可以使用PHP来操作HTML以将活动类移动到另一个选项卡。

<?php
$signinTabIsActive = "active";
$signupTabIsActive = "";

if(isset($_POST['firstname'])){
   $signinTabIsActive = "";
   $signupTabIsActive = "active";
?>

<!-- Tabs -->
    <nav class="register-nav">
        <div class="nav nav-tabs nav-justified" id="nav-tab" role="tablist">
            <a class="nav-item nav-link <?= $signinTabIsActive; ?>" id="nav-signin-tab" data-toggle="tab" href="#nav-signin" role="tab">Sign in</a>
            <a class="nav-item nav-link <?= $signupTabIsActive; ?>" id="nav-signup-tab" data-toggle="tab" href="#nav-signup" role="tab">Create New Account</a>
        </div>
    </nav>

Answer 2

添加一个隐藏输入，其值指示应打开哪个窗格。生成表单（使用Php）时，根据$ _POST数组中的此值确定哪个窗格获取活动类

提交表单而不使用PHP更改选项卡窗格
