Question

某些变量用于phtml文件，不能在php文件中使用。我也尝试使用GLOBAL变量范围，但它对我没有帮助。单击“提交”按钮后，我需要执行display（）函数。在功能显示（）中，我写了一个条件，点击“提交”按钮后执行，然后我想收到下载文件的ID，用于在提交按钮下面生成下载链接。的错误：

Undefined index: $fileId in C:\wamp64\www\index.phtml on line 24

我的代码： PHTML文件

<?php global $fileId; ?>
<body>
   <?php 
        function displayID()
        {   
            //$fileId = '5';
            if($fileId ?? TRUE) 
            {
                echo $fileId;
            } else { echo 'Not working'; }
        }            
    ?>

    <div style="border-bottom: 2px solid black; border-top: 2px solid black; background-color: white; width: 25%; text-align: center; display: block; margin: auto; ">
        <?php foreach ($files as $file) { ?>
            <p style="text-align: inherit"><?php echo $file; ?></p>
            <?php  ?>
        <?php } ?>
    </div>

    <div style="text-align: center; float: inherit; margin-top: 5%">
        <form method="post" action="<?php echo $_SERVER['PHP_SELF']?>">
            <input type="submit" value="Upload" name="submit"><br><br>
        </form>
        <form method="GET" action="<?php echo $_SERVER['PHP_SELF']?>">
            <input type="submit" value="Get Link" name="Get"><br><br>
        </form>
        <br>
        <div style="border-bottom: 2px solid black; border-top: 2px solid black; background-color: white; width: 25%; text-align: center; display: block; margin: auto; ">
            <p> 
            <?php 
                if (isset($_GET['Get']))
                    {
                       displayID();
                    } else {
                        echo '';
                    }
            ?> 
            </p>
        </div>
    </div>
