Question

我在尝试使用fopen在textarea到.txt文件中写入文本行时遇到问题。这是我的代码，希望有人可以提供帮助！

<?php
    session_start();
    if (!isset($_SESSION['username'])) {
        $_SESSION['msg'] = "You must log in first";
        header('location: login.php');
    }
    if (isset($_GET['logout'])) {
        session_destroy();
        unset($_SESSION['username']);
        header("location: login.php");
    }
    $username = $_SESSION['username'];
    $file = "extra/" . $username . ".png";
    if (!file_exists($file)) $file = 'extra/defaultProfile.png';
    function sendData($u) {
        $myfile = fopen('bio/' . $username . '.txt', $u);
    }
?>

        <div class="profilename">
            <p style="position: absolute; top: 8px; left: 130px; color: white; font-size: 30px;"><?php echo $username ?></p>
        </div>
        <div class="biotext">
            <form action="" method="post">
                <textarea name="lines" width=25% height=9.5% background-color='white' style="position: absolute; top: 75px; left: 132.5px;"></textarea>
                <input type="submit" name="submit" value="submit" formaction="sendData()"/>
            </form>
        </div>
    </body>
    <footer>
        <div class="status">Currently logged in as <?php echo $username ?></div>
    </footer>
</html>

我已经尝试了所有可能出现的但我似乎无法找到正确的解决方案......我尝试制作并使用名为sendData()的函数，但这也不起作用。非常感谢任何人提供的任何帮助，谢谢！

检查文件是否存在
检查是否授予了写入文件的权限
sendData（）它的php，你从html中调用它
你忘了在调用函数

你可以这样做：

<?php
  if (!empty($_POST))
  {
    $text_data = $_POST['text_data'];
    $username = $_POST['username'];
    fopen('bio/' . $username . '.txt', $text_data);
  }
?>

<link rel="stylesheet" type="text/css" href="css/main.css">
<header>
    <div class="container">
      <nav>
        <ul>
          <li><a href="index.php">Home</a></li>
          <li><a href="downloads.php">Downloads</a></li>
          <li><a href="chat.php">Chat</a></li>
          <li><a href="profile.php">Profile</a></li>
          <li class="logout"><a href="index.php?logout='1'">Logout</a></li>
        </ul>
      </nav>
    </div>
  </header>
<body>
  <div class="profileimg">
    <img src=<?php echo $file; ?>  width="125" height="125">
  </div>
  <div class="profilename">
    <p style="position: absolute; top: 8px; left: 130px; color: white; font-size: 30px;"><?php echo $username ?></p>
  </div>
    <div class="biotext">
        <form action="" method="post">
        <textarea name="lines" width=25% height=9.5% background-color='white' style="position: absolute; top: 75px; left: 132.5px;"></textarea>
        <input type="text" name="text_data" value="">
        <input type="hidden" name="username" value="<?php echo $username ?>">
        <input type="submit" name="submit" value="submit"/>
        </form>
