Question

我的php函数mail（）有问题。它不会发送任何电子邮件:(。我是php的新手，并通过使用大量教程创建代码，所以我认为这可能是错误的。

此外，我在按钮代码下面的验证有问题。我想验证用户是否输入了有效的电子邮件，如果没有，则回显任何内容，因为它无论如何都会显示红色错误。

现在，当电子邮件无效时，它会显示“已发送电子邮件”消息但首先我要通过电子邮件实际发送。

如果没有标题“From ::”，托管也会阻止SSL协议。它被正确放置了吗？

<?php
$NameErr = $EmailErr = $SubErr = $MessErr = "";
$Name = $Email = $Subject = $Message = "";
$To = "blackmagic@xxx.com";
$headers = "From: blackmagic@xxx.com Name: $Name\n $Message\n E-Mail: $Email\n";
$n = NULL;
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (empty($_POST["Name"])) {
        $NameErr = "Name is required";
    } else {
        $Name = test_input($_POST["Name"]);
    }
    if (!preg_match("/^[a-zA-Z ]*$/", $Name)) {
        $NameErr = "Only letters and white space allowed!";
    }
    if (empty($_POST["Email"])) {

据我了解，您发送邮件时遇到问题，如果没有标题“From ::”，则Hosting会阻止SSL协议。它被正确放置了吗？

我的解决方案是您的邮件不发送和用户邮件验证问题。这是我经常用来发送邮件的代码，它的工作非常好。

div id=existing-translation

PHP - 函数邮件不起作用
