PHP与我们联系表单重新发送页面时

我在PHP方面还很陌生,并且正在尝试为我的网站建立一个简单的联系我们。我有发送表单,但是由于某种原因,每次我重新加载页面时,它也发送空白消息。我在下面贴了一些表格。

这里有任何帮助/您可以提供的任何提示。

   <?php

    $name_error = "";
    $name = "";

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        if (empty($_POST["name"])) {
            $name_error = "Whoops! Please enter your full name";
        } else {
            $name = test_input($_POST["name"]);

            if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
                $name_error = "Whoops! Only letters and white spaces are allowed in a name";
            }
        }

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

        $to = 'myemail@gmail.com';
        $subject = 'Contact Us Form Submission';

        if (mail($to, $subject, $message_body )){
            $success = "Your message has been sent. A representative will be in contact with you shortly.";
            $name = $email = $phone = $message = $inquiry = $hear = $success = '';
        }
    }   
    function test_input($data) {
        $data = trim($data);
        $data = stripslashes($data);
        $data = htmlspecialchars($data);
        return $data;
    }
?>

您的“邮件”逻辑需要放在服务器请求方法中,一个简单的解决方法是将if逻辑复制到邮件逻辑中。即

if($_SERVER["REQUEST_METHOD"] == "POST"){
  if (mail($to, $subject, $message_body )){
    $success = "Your message has been sent. A representative will be in contact with you shortly.";
    $name = $email = $phone = $message = $inquiry = $hear = $success = '';
  }
}

当然,您也可以删除当前的if语句并放在方括号中,然后将其放在代码末尾(因为不需要那么早就破坏if语句)

<?php

$name_error = "";
$name = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (empty($_POST["name"])) {
        $name_error = "Whoops! Please enter your full name";
    } else {
        $name = test_input($_POST["name"]);

        if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
            $name_error = "Whoops! Only letters and white spaces are allowed in a name";
        }
    }

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

    $to = 'myemail@gmail.com';
    $subject = 'Contact Us Form Submission';

    if (mail($to, $subject, $message_body )){
        $success = "Your message has been sent. A representative will be in contact with you shortly.";
        $name = $email = $phone = $message = $inquiry = $hear = $success = '';
    }
}

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