表格提交後，如果用戶已經登錄，然後表格將提交其他登錄優先，然後形式應該提交自動

Question

我想實現一個表格，如果用戶已經登錄然後從提交，否則登錄，然後形式應提交自動在cookie的幫助下，我的代碼在上一次move_uploaded_file中播放了一個錯誤。

我的代碼被賦予

不是一個解決辦法如下，以你的問題：你有沒有分配給您select菜單名稱。

除此之外，您需要檢查是否存在會話變量 - 假設您在用戶登錄時設置某種會話變量？即：$_SESSION['username']='fred'等？您可以生成將在頁面加載時提交表單的JavaScript。

<form name="appointment" method="POST" action="appointment.php" role="form"> 
    <!-- form contents --> 
</form> 

<?php 
    if(isset($_SESSION['username'])){ 
     echo " 
      <script type='text/javascript'> 
       document.querySelectorAll(form['name=\"appointment\"]')[0].submit(); 
      </script>"; 
    } 
?>
