我不知道在哪里关闭表中的 td 标签

Question

我有以下代码，它确实在下拉框中显示了所有选项，但我刚刚注意到我在某处缺少</td>。我试图将</td> 放在我的第二个选项标签之后，但由于某种原因，它不起作用......只需在表格之外显示我的所有选项：这是我的代码：我试图将 td 标签放在所有有点地方，但我什至不确定我是否需要这里的 td .....

<?php
include_once __DIR__.'/header2.php';

  echo "<meta http-equiv='refresh' content='0;url=index.php?create_music_sub=notlogin'>"; 
   exit();
} else {
if($_SESSION['u_permission'] == 0){
    echo "<meta http-equiv='refresh' content='0;url=header2.php?create_music_sub=nopermission'>"; 
    exit();
} else {

    $date = date("Y-m-d H:i:s");


    $sql = "SELECT * FROM music_forum_cats;";

                 $stmt = mysqli_stmt_init($conn);

                if(!mysqli_stmt_prepare($stmt, $sql)) {
                       echo "SQL error";

您应该删除每个<option> 标记之后的“</td>”，在所有<option> 标记之后添加一个结束标记“</select>”，然后在此处添加</td>。我认为验证你的输出可以帮助你。尝试使用this tool
