我需要帮助来扩展我的 PHP 脚本。我需要必填字段和注册表单中电子邮件字段的验证。

这是我的代码，我尝试使用不同的 if 和 echo 代码，但在其中没有任何作用。

<?php

$email = $_POST['email'];
$from = $email;

$to = "xy@gmail.com";
$subject = "SIGN UP";

$emailbody = "";
$emailbody .= "Email: " . $email . "\n";

$header = "";
$header .= "From:" . $from . " \n";
$header .= "Content-Type:text/plain;charset=utf-8";

// Sending message
$success = mail($to, $subject, $emailbody, $header);

if ($success){
print "<meta http-equiv=\"refresh\" content=\"0;URL=confirmation_signup.html\">";
}
else{
print "<meta http-equiv=\"refresh\" content=\"0;URL=error.html\">";
}
?>

代码有效，电子邮件已送达，但如果未填写字段，则表单不应该成功。提前谢谢您。

您可以检查电子邮件字段是否为空，然后您可以filter_var用来验证提供的电子邮件。

这是一个例子

<?php
if(!empty($_POST['email']) && (!filter_var($email, FILTER_VALIDATE_EMAIL) === false) )
{
    $email = $_POST['email'];
    $from = $email;

    $to = "xy@gmail.com";
    $subject = "SIGN UP";

    $emailbody = "";
    $emailbody .= "Email: " . $email . "\n";

    $header = "";
    $header .= "From:" . $from . " \n";
    $header .= "Content-Type:text/plain;charset=utf-8";

    // Sending message
    $success = mail($to, $subject, $emailbody, $header);

    if ($success)
    {
        print "<meta http-equiv=\"refresh\" content=\"0;URL=confirmation_signup.html\">";
    }
    else
    {
    print "<meta http-equiv=\"refresh\" content=\"0;URL=error.html\">";
    }
}
else print "<meta http-equiv=\"refresh\" content=\"0;URL=error.html\">";
?>

问题解决了，但又出现了一个问题。html 表单无法正确发送邮件。我尝试了六个邮件地址。如果有人提交表格，邮件有时会发送到其中一个 - 有时会发送到另一个 - 有时会发送到没有地址。我听说不要使用常规的 mail() 命令。有人可以告诉我吗？

<?php
if(!empty($_POST['email']) && !empty($_POST['name']) && !empty($_POST['message']) && (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) === false)){

$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = $email;
$to = "test@test.com";
$subject = "SUPPORT";

$emailbody = "";
$emailbody .= "Full name: " . $name . "\n";
$emailbody .= "Email: " . $email . "\n";
$emailbody .= "Message: " . $message . "\n";

$header = "";
$header .= "From:" . $from . " \n";
$header .= "Content-Type:text/plain;charset=utf-8";

$success = mail($to, $subject, $emailbody, $header);

if ($success){
print "<meta http-equiv=\"refresh\" content=\"0;URL=de/confirmation.html\">";
}
else{
print "<meta http-equiv=\"refresh\" content=\"0;URL=de/error.html\">";
}
}
else print "<meta http-equiv=\"refresh\" content=\"0;URL=de/error.html\">";
?>

似乎电子邮件是您从 POST 中收集的唯一内容，因此请先检查它是否为空，然后验证它：

<?php

if(!empty($_POST['email']) && (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) === false)){

  $email = $_POST['email'];
  $from = $email;

  $to = "xy@gmail.com";
  $subject = "SIGN UP";

  $emailbody = "";
  $emailbody .= "Email: " . $email . "\n";

  $header = "";
  $header .= "From:" . $from . " \n";
  $header .= "Content-Type:text/plain;charset=utf-8";

  // Sending message
  $success = mail($to, $subject, $emailbody, $header);

  if ($success){
  print "<meta http-equiv=\"refresh\" content=\"0;URL=confirmation_signup.html\">";
  }
  else{
  print "<meta http-equiv=\"refresh\" content=\"0;URL=error.html\">";
  }
}
else echo "email required";
?>

在它到达服务器之前，您可以通过首先进行一些客户端验证来帮助您的用户，以确保输入是电子邮件，并且是必需的。
