Question

我创建了一个HTML表单，它应该使用PHP将输入的文本提交到.txt文件中，但它只会创建一个空行，我不知道问题是什么。

非常感谢帮助！

<form class="form-inline validate" name="form1" method="post" action="signup.php" target="_blank" novalidate>
    <div class="row no-gutter">
        <div class="col-sm-9">
            <input type="email" value="" name="mail" class="form-control" placeholder="Subscribe to our newsletter" required>
        </div>
        <div class="col-sm-3">
            <input type="submit" value="SUBSCRIBE" name="Submit">
        </div>

    </div>
</form>

<?php

$username = $_POST['user'];

//the data

$data = "$email\n";

//open the file and choose the mode

$fh = fopen("users.txt", "a");
fwrite($fh, $data);

//close the file

fclose($fh);
print "User Submitted";

?>

如果您想将邮件更改为

   <?php
    if(isset($_POST['Submit'])){
       $email = $_POST['mail'];

      //the data

      $data = "$email\n";

      //open the file and choose the mode

      $fh = fopen("users.txt", "a+");
      fwrite($fh, $data);

      //close the file

      fclose($fh);
      print "User Submitted";
    }
    ?>

HTML表单用PHP将内容提交到.txt文件 - 空白？
