php - 将网站表单转换为 PDF 并通过电子邮件发送给网站管理员

Question

我正在尝试为我的网站创建一个表单，提交后将转换为 PDF 并通过电子邮件发送给我自己(网站管理员)。

我知道我无法纯粹使用 JQuery/Javascript 来完成该操作，我需要使用 PHP 来发送电子邮件。

将 HTML 转换为 PDF 的 Javascript

var doc = new jsPDF(); 
var specialElementHandlers = { 
    '#editor': function (element, renderer) { 
        return true; 
    } 
};
$('#submitformz').click(function () { 
    doc.fromHTML($('#content').html(), 15, 15, { 
        'width': 190, 
            'elementHandlers': specialElementHandlers 
    }); 
    doc.save('sample-page.pdf');  
});

我遇到的问题是，它会转换为 PDF，然后下载到用户计算机上。理想情况下，我想转换“doc.save”，以便它与 PHP 结合以通过电子邮件发送文档

PHP:

if(isset($_POST['email'])) {

    $email_to = "webmaster@website.com";
    $email_subject = "Your email subject line";

    function died($error) {
        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();
    }

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);

或者...有什么方法可以修改 Javascript，以便不再将文件下载到客户计算机上，而是下载到我网站后端的媒体库中？

如果我目前理解你，你应该从客户端和前端获取数据，然后在后端使用 php 创建 PDF(你可以使用 wkhtmltopdf 将 HTML(由后端数据生成)转换为 PDF)，然后通过电子邮件发送此 PDF 文件。
