听起来您有两个问题，一个是验证问题，另一个是发送电子邮件问题。首先解决最简单的问题：首先看看您的邮件设置是否正确——php是否可以正常发送电子邮件，或者这是您的代码有问题吗？我使用以下php脚本来告诉我服务器是否正确设置为发送电子邮件：
<?php 
    ini_set( 'display_errors', 1 );
    error_reporting( E_ALL );
    $from = "<YOUR EMAIL>";
    $to = "<YOUR EMAIL>";
    $subject = "PHP Mail Test script";
    $message = "This is a test to check the PHP Mail functionality";
    $headers = "From:" . $from;
    mail($to,$subject,$message, $headers);
    echo "Test email sent";
?>



它不工作，你需要配置服务器让php发送电子邮件。我喜欢使用ssmtp守护进程来简化向SMTP服务器发送电子邮件的过程
至于验证代码，很难理解。您是否考虑过改用验证库？您甚至可以使用原始HTML5——请参见此处：
但如果您真的想使用自己的php验证器，我个人会编写如下内容：
<?php 
$validation_elements = array(
    'nume' => function() {
        if (!isset($_POST['nume'])) return 'You must enter your nume';
        if (!preg_match('/^[a-zA-Z]{1,}$/',$_POST['nume']) return 'Your nume can only be letters.;'
        return false;
    },
    'prenume' => function() {
        if (!isset($_POST['Mandatory'])) return 'Your prenume is mandatory';
        if (!preg_match('/^[a-zA-Z]{1,}$/',$_POST['prenume'])) return "Your presume can only consist of letters";
        if (strlen($_POST['prenume'])<3) return "Your presume is too short.";   
        return false;
    }, 
    'tel' => function() {
        if (!isset($_POST['tel']) return false; // in this example tel is not mandatory but must match the following rule if it is present:
        if ( !preg_match('/^[0-9]{4}[\s.]{0,1}[0-9]{3}[\s.]{0,1}[0-9]{3}$/', $_POST['tel']) && !preg_match('/^[0-9]{3}[\s.]{0,1}[0-9]{3}[\s.]{0,1}[0-9]{2}[\s.]{0,1}[0-9]{2}$/', $_POST['tel']) && ($_POST['tel'] != '-')) return '&nbsp;Mask: 021.021.02.01 or 0740.123.456 or -';

        if (strlen($_POST['mesaj'])<15) return 'Mesaj too short. Min. 15 chars';
        if (strlen($_POST['mesaj'])>150) return 'Mesaj too long. Max 150 chars.';
        return false;
    }
}

我前面的答案的问题是它不可移植——你不能把代码带到别处使用。在我之前的回答中，我暗示有另一种更好的方法来编写验证例程。给你。它更复杂，但只是稍微复杂一点
