联系表格仅发送消息正文但忽略其他字段

Question

请大家麻烦大了，过去 24 小时我一直在大汗淋漓，我有这个联系表格，我上传到我的服务器，但可悲的是，它只是将消息正文发送到我的电子邮件，忽略姓名字段、电子邮件字段和电话号码等其他字段。我厌倦了盯着 php 代码，我觉得一切正常，但代码没有按预期工作，请帮助我。

这是我的 php 代码：

<?php 

// define variables and set to empty values
$name_error = $email_error = $phone_error = $url_error = "";
$name = $email = $phone = $message = $url = $success = "";

//form is submitted with POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (empty($_POST["name"])) {
    $name_error = "Name is required";
  } else {
    $name = test_input($_POST["name"]);
    // check if name only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
      $name_error = "Only letters and white space allowed"; 
    }
  }

  if (empty($_POST["email"])) {
    $email_error = "Email is required";
  } else {
    $email = test_input($_POST["email"]);
    // check if e-mail address is well-formed
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $email_error = "Invalid email format"; 
    }
  }

  if (empty($_POST["phone"])) {
    $phone_error = "Phone is required";
  } else {
    $phone = test_input($_POST["phone"]);
    // check if e-mail address is well-formed
    if (!preg_match("/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3}[\s-]?\d{4}$/i",$phone)) {
      $phone_error = "Invalid phone number"; 
    }
  }

  if (empty($_POST["url"])) {
    $url_error = "";
  } else {
    $url = test_input($_POST["url"]);
    // check if URL address syntax is valid (this regular expression also allows dashes in the URL)
    if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$url)) {
      $url_error = "Invalid URL"; 
    }
  }

  if (empty($_POST["message"])) {
    $message = "";
  } else {
    $message = test_input($_POST["message"]);
  }

  if ($name_error == '' and $email_error == '' and $phone_error == '' and $url_error == '' ){
      $message_body = '';
      unset($_POST['submit']);
      foreach ($_POST as $key => $value){
          $message_body .=  "$key: $value\n";
      }

      $to = 'emmanuelgbnn23@gmail.com';
      $subject = 'Contact Form Submit';
      if (mail($to, $subject, $message)){
          $success = "Message sent, thank you for contacting us!";
          $name = $email = $phone = $message = $url = '';
      }
  }

}

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}

这是我的html代码：

<?php include('form_process.php'); ?>
<link rel="stylesheet" href="form.css" type="text/css">
<div class="container">  
  <form id="contact" action="<?= htmlspecialchars($_SERVER["PHP_SELF"]) ?>" method="post">
    <h3>Contact</h3>
    <h4>Contact us today, and get reply with in 24 hours!</h4>
    <fieldset>
      <input placeholder="Your name" type="text" name="name" value="<?= $name ?>" tabindex="1" autofocus>
      <span class="error"><?= $name_error ?></span>
    </fieldset>
    <fieldset>
      <input placeholder="Your Email Address" type="text" name="email" value="<?= $email ?>" tabindex="2">
      <span class="error"><?= $email_error ?></span>
    </fieldset>
    <fieldset>
      <input placeholder="Your Phone Number" type="text" name="phone" value="<?= $phone ?>" tabindex="3">
      <span class="error"><?= $phone_error ?></span>
    </fieldset>
    <fieldset>
      <input placeholder="Your Web Site starts with http://" type="text" name="url" value="<?= $url ?>" tabindex="4" >
      <span class="error"><?= $url_error ?></span>
    </fieldset>
    <fieldset>
      <textarea value="<?= $message ?>" name="message" tabindex="5">
      </textarea>
    </fieldset>
    <fieldset>
      <button name="submit" type="submit" id="contact-submit" data-submit="...Sending">Submit</button>
    </fieldset>
    <div class="success"><?= $success ?></div>
  </form>
</div>

您在 mail() 函数中使用了错误的变量 $message。由于您要将值附加到 $message_body 中，请将脚本中的 $message 替换为 $message_body 并重试。

<?php 

    // define variables and set to empty values
$name_error = $email_error = $phone_error = $url_error = "";
$name = $email = $phone = $message = $url = $success = "";

//form is submitted with POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (empty($_POST["name"])) {
        $name_error = "Name is required";
    } else {
        $name = test_input($_POST["name"]);
    // check if name only contains letters and whitespace
        if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
            $name_error = "Only letters and white space allowed"; 
        }
    }

    if (empty($_POST["email"])) {
        $email_error = "Email is required";
    } else {
        $email = test_input($_POST["email"]);
    // check if e-mail address is well-formed
        if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
            $email_error = "Invalid email format"; 
        }
    }

    if (empty($_POST["phone"])) {
        $phone_error = "Phone is required";
    } else {
        $phone = test_input($_POST["phone"]);
    // check if e-mail address is well-formed
        if (!preg_match("/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3}[\s-]?\d{4}$/i",$phone)) {
            $phone_error = "Invalid phone number"; 
        }
    }

    if (empty($_POST["url"])) {
        $url_error = "";
    } else {
        $url = test_input($_POST["url"]);
    // check if URL address syntax is valid (this regular expression also allows dashes in the URL)
        if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$url)) {
            $url_error = "Invalid URL"; 
        }
    }

    if (empty($_POST["message"])) {
        $message = "";
    } else {
        $message = test_input($_POST["message"]);
    }

    if ($name_error == '' and $email_error == '' and $phone_error == '' and $url_error == '' ){
        $message_body = '';
        unset($_POST['submit']);
        foreach ($_POST as $key => $value){
            $message_body .=  "$key: $value\n";
        }

        $to = 'emmanuelgbnn23@gmail.com';
        $subject = 'Contact Form Submit';
        if (mail($to, $subject, $message_body)){
            $success = "Message sent, thank you for contacting us!";
            $name = $email = $phone = $message = $url = '';
        }
    }

}

function test_input($data) {
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
}

?>

更改您的代码

if ($name_error == '' and $email_error == '' and $phone_error == '' and $url_error == '' )

到这里

if ($name_error == '' && $email_error == '' && $phone_error == '' && $url_error == '' )
