我有一个简单的联系表格。它通过AJAX发送电子邮件。工作正常。
现在我需要从此表单的结果创建PDF文件并将其下载到用户here
所以HTML格式:
<form id="contact-form">
<input type="hidden" name="action" value="contact_send" />
<input type="text" name="name" placeholder="Your name..." />
<input type="email" name="email" placeholder="Your email..." />
<textarea name="message" placeholder="Your message..."></textarea>
<input type="submit" value="Send Message" />
</form>
在functions.php中我有发送电子邮件的功能:
function sendContactFormToSiteAdmin () {
try {
if (empty($_POST['name']) || empty($_POST['email']) || empty($_POST['message'])) {
throw new Exception('Bad form parameters. Check the markup to make sure you are naming the inputs correctly.');
}
if (!is_email($_POST['email'])) {
throw new Exception('Email address not formatted correctly.');
}
$subject = 'Contact Form: '.$reason.' - '.$_POST['name'];
$headers = 'From: My Blog Contact Form <contact@myblog.com>';
$send_to = "contact@myblog.com";
$subject = "MyBlog Contact Form ($reason): ".$_POST['name'];
$message = "Message from ".$_POST['name'].": \n\n ". $_POST['message'] . " \n\n Reply to: " . $_POST['email'];
if (wp_mail($send_to, $subject, $message, $headers)) {
echo json_encode(array('status' => 'success', 'message' => 'Contact message sent.'));
exit;
} else {
throw new Exception('Failed to send email. Check AJAX handler.');
}
} catch (Exception $e) {
echo json_encode(array('status' => 'error', 'message' => $e->getMessage()));
exit;
}
}
add_action("wp_ajax_contact_send", "sendContactFormToSiteAdmin");
add_action("wp_ajax_nopriv_contact_send", "sendContactFormToSiteAdmin");
所以在footer.php中我有一个脚本ajax处理程序:
jQuery(document).ready(function ($) {
$('#contact-form').submit(function (e) {
e.preventDefault(); // Prevent the default form submit
var $this = $(this); // Cache this
$.ajax({
url: '<?php echo admin_url("admin-ajax.php") ?>', // Let WordPress figure this url out...
type: 'post',
dataType: 'JSON', // Set this so we don't need to decode the response...
data: $this.serialize(), // One-liner form data prep...
beforeSend: function () {},
error: handleFormError,
success: function (data) {
if (data.status === 'success') {
handleFormSuccess();
} else {
handleFormError(); // If we don't get the expected response, it's an error...
}
}
});
});
});
所有这些都很棒。但我不明白我在哪里粘贴代码用于创建PDF,我试图将其粘贴到sendContactFormToSiteAdmin
php函数中,但它没有用。
在this example中,我需要将此代码完全粘贴到sendContactFormToSiteAdmin
php函数中:
ob_start();
?>
<h1>Data from form</h1>
<p>Name: <?php echo $name;?></p>
<p>Email: <?php echo $email;?></p>
<?php
$body = ob_get_clean();
$body = iconv("UTF-8","UTF-8//IGNORE",$body);
include("mpdf/mpdf.php");
$mpdf=new \mPDF('c','A4','','' , 0, 0, 0, 0, 0, 0);
$mpdf->WriteHTML($body);
$mpdf->Output('demo.pdf','D');
但我不明白如何用ajax响应来做到这一点。
修改 正如Shoaib Zafar评论的那样,如果可以通过电子邮件发送pdf文件作为电子邮件的附件,当然对我来说这是最好的。
答案 0 :(得分:0)
要将PDF作为附件发送电子邮件,您需要更改电子邮件发送功能。
vte_terminal_spawn_async()
我不太了解wp_email函数的工作原理,但从技术上讲,这段代码应该可行,你只需要重构它。 您也可以在官方文档中找到它,以了解有关它的更多信息mPDF Example #3
