Question

我有一个联系表格，其中包含以下字段：

名字
姓氏
电话
电子邮件
和评论

每当用户将此表单提交到我的电子邮件时，主题值应该是自动的 PHP自动生成的数字。

这是我到目前为止所拥有的

<?php

if(isset($_POST['email'])) {
    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "wouldn't want some spam mail would ya?";      
    $email_subject = "New Property From Customer";

    function died($error) {   
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";

        die();
    }

    // validation expected data exists
    if (!isset($_POST['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');      
    }

    $first_name = $_POST['first_name']; // required
    $last_name = $_POST['last_name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['comments']; // required

    $error_message = "";

    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

    if (!preg_match($email_exp,$email_from)) {
        $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
    }

    $string_exp = "/^[A-Za-z .'-]+$/";

    if (!preg_match($string_exp,$first_name)) {
        $error_message .= 'The First Name you entered does not appear to be valid.<br />';
    }

    if (!preg_match($string_exp,$last_name)) {
        $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
    }

    if (strlen($comments) < 2) {
        $error_message .= 'The Comments you entered do not appear to be valid.<br />';
    }

    if(strlen($error_message) > 0) {
        died($error_message);
    }

    $email_message = "Form details below.\n\n";

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";

    // create email headers
    $headers = 'From: '.$email_from."\r\n" .
               'Reply-To: '.$email_from."\r\n" .
               'X-Mailer: PHP/' . phpversion();

    @mail($email_to, $email_subject, $email_message, $headers); 

?> 

<!-- include your own success html here -->

Your Property has been Posted please check your email address.

<?php

}

?>

Answer 1

嗯，你没有指定你想从哪里获得这个号码。既然你说生成我会假设你是在现场创建的。所以也许可以添加$email_subject之类的$rand(100,1000)这样的结尾？

也许你应该澄清你的要求？

旁注：考虑使用filter_var($email_a, FILTER_VALIDATE_EMAIL)来检查电子邮件，而不是一些preg_match。关于here的更多信息。

Answer 2

生成随机数，简单地用户rand（）函数如下

echo rand($fromRange,$toRange);

您将获得指定范围之间的随机数

在联系表单的主题行中生成一个数字
