我正在构建自定义主题,并且我想在我的联系页面上使用AJAX发送电子邮件。通过进行一些研究,我找到了一种方法来实现这一目标。
首先,在提交表单后,我使用常规javascript进行了一些验证:
const contactFormSubmit = () => {
const submitButton = document.querySelector('#contact-submit');
console.log(submitButton);
document.addEventListener('click', e => {
if (e.target == submitButton) {
e.preventDefault();
const name = document.getElementById('name').value;
const email = document.getElementById('email').value;
const message = document.getElementById('message').value;
checkForm(name, email, message);
}
})
}
此代码只是简单地预设了默认值并获取输入数据。然后将数据发送到checkForm()函数以检查是否有任何错误。
const checkForm = (name, email, message) => {
if (name && message && email) {
if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(email)) {
jQuery.ajax({
url: `<?php echo admin_url('admin-ajax.php'); ?>`,
type: "POST",
cache: false,
data:{
action: 'send_email',
name: name,
email: email,
message: message,
},
success:function(res){
alert("Email Sent.");
}
});
printMessage('success', 'Thank you for you email. We will get back to you as soon as we can');
} else {
printMessage('error', 'email is not in the correct form')
}
} else {
printMessage('error', 'Make Sure all fields are filled out')
}
}
如果有错误,它将通过将其发送到printMessage来错误显示消息。
const printMessage= (outcome, message) => {
if (!messageOn) {
resultMessageContainer = document.createElement('div');
pageContent = document.querySelector('.contact-container');
document.body.insertBefore(resultMessageContainer, pageContent);
} else {
resultMessageContainer.innerHTML = '';
}
if (outcome == 'success') {
resultMessageContainer.innerHTML = `${outcome} ${message}`;
console.log('SUCCESS');
messageOn = true;
} else if (outcome == 'error') {
resultMessageContainer.innerHTML = `${outcome} ${message}`;
console.log('failure');
messageOn = true;
}
}
如果没有错误,我们应该向后端发出ajax请求。然而。在发送此ajax请求时,出现以下错误:
jquery.min.js:4 POST http://elbe.local/contact-us/%3C?php%20echo%20admin_url(%27admin-ajax.php%27);%20?%3E 404 (Not Found)
从错误中可以看出问题出在admin-ajax.php文件。我的javascript文件位于单独的文件中,也许与此有关。
在我的functions.php中,这是负责发送电子邮件的函数。
add_action( 'wp_ajax_send_email', 'callback_send_email' );
add_action( 'wp_ajax_nopriv_send_email', 'callback_send_email' );
function callback_send_email(){
$name = $_REQUEST['name'];
$email = $_REQUEST['email'];
$message= $_REQUEST['message'];
$subject = "Contact Form";
$email_body = "The following prospectus has contacted you.<br>".
"Name: $name. <br>".
"Email: $email. <br>".
"Message: $message. <br>";
$to = "naderabouezze93@gmail.com";
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= "From: $name <$email> \r\n";
$headers .= "Reply-To: $email \r\n";
$mail = mail($to,$subject,$email_body,$headers);
if($mail){
echo "Email Sent Successfully";
}
die();
}
有关如何进行这项工作的任何指导将不胜感激。谢谢!

如 @ADyson 所述,如果此文件位于.js文件中,则不会执行PHP代码,因此您应该通过隐藏的输入来获取它,例如:
<input type="hidden" value="<?= admin_url('admin-ajax.php'); ?>" name=ajaxURL >
在PHP文件中包含以上代码,可能在 header.php 或 footer.php
中然后您可以这样获取:
url:jQuery('input [name = ajaxURL]')。val(),
