javascript - 根据输入表单中输入的内容分别弹出不同的表单

Question

早上好，我修改了一些教程代码，使其分别针对在称为版本的输入表单中键入的版本名称显示不同的帐户创建表单。无论我在此处输入什么版本名称，都会出现完整版本的选项。我正在使用 bootstrap 和 jquery。这是什么问题？

                <?php  
                if(isset($_SESSION['username']))  
                {  
                ?>  
                <div align="center">  
                     <h1>Welcome - <?php echo $_SESSION['username']; ?></h1><br />

                     <?php if ($_SESSION['version'] = "full") { ?>
  <form action="fullfinalinserting.php" method="post" enctype="multipart/form-data">
                  <div class="row">
