检测PHP Mailer错误并使用jquery在网站中打印消息

我正在使用PhpMailer发送电子邮件。 在我自己的脚本中，我想在下面的if语句中解析一些javascript。 请注意，我已启用html。

当没有发送电子邮件时，我想在.done函数中解析一些未发送电子邮件的javascript。 例如complete.html("Message Not Sent!"); 发送电子邮件时，我想显示电子邮件已发送。 我怎么能这样做，哪里更好，在PHP文件内或在JavaScript中？

  var form = $('#contact'); form.submit(function(event) { event.preventDefault(); var complete = $('#formAppend'); var $form = $(this); var name = $("#fname").val(); var email = $("#email").val(); var Message = $("#msg").val(); var countryoption = $("#country").val(); $.ajax({ type: 'POST', url: '../sendemail.php', data: { Name: name, Email: email, message: Message, Country: countryoption }, beforeSend: function() { complete.html('Message is Sending...').fadeIn(); } }) .done(function(data) { //This should change depending on the php if statement at the bottom. complete.html("Message Sent"); }); }); //end contact form

PHP：

 isSMTP(); $mail->Debugoutput = 'html'; $mail->Host = 'smtp.gmail.com'; $mail->Port = 587; $mail->SMTPSecure = 'tls'; $mail->SMTPAuth = true; $mail->Username = ''; $mail->Password = ''; $mail->SetFrom($from, $from_name); $mail->Subject = "Εμβολιασμός Δέντρων ~ Φόρμα Επικοινωνίας ~ $body "; $mail->CharSet = 'UTF-8'; $mail->isHTML(true); // Set email format to HTML $Country = $_POST["Country"]; $mail->Body = "BLABLA ";//end email body $mail->AddAddress($to); //send the message, check for errors if (!$mail->send()) { //Message not sent echo "Mailer Error: " . $mail->ErrorInfo; } else {//Message sent! echo "Well done $from_name, your message has been sent!\nWe will reply to the following email: $from" . "
Your Message: $body"; } } //end function smtpmailer ?>

改变你这样的PHP和JS代码……..

 require 'PHPMailer-master/PHPMailerAutoload.php'; if (empty($_POST['Email'])) { $_POST['Email'] = ""; } if (empty($_POST['Name'])) { $_POST['Name'] = ""; } if (empty($_POST['message'])) { $_POST['message'] = ""; } if (isset($_POST["message"]) && !empty($_POST["message"])) { $mymail = smtpmailer("[e-mail]", $_POST['Email'], $_POST['Name'], $_POST['message']); } else { header('Location: http://webdominar.xyz'); exit(); } function smtpmailer($to, $from, $from_name, $body) { $mail = new PHPMailer; $mail->isSMTP(); $mail->Debugoutput = 'html'; $mail->Host = 'smtp.gmail.com'; $mail->Port = 587; $mail->SMTPSecure = 'tls'; $mail->SMTPAuth = true; $mail->Username = ''; $mail->Password = ''; $mail->SetFrom($from, $from_name); $mail->Subject = "Εμβολιασμός Δέντρων ~ Φόρμα Επικοινωνίας ~ $body "; $mail->CharSet = 'UTF-8'; $mail->isHTML(true); // Set email format to HTML $Country = $_POST["Country"]; $mail->Body = "BLABLA "; //end email body $mail->AddAddress($to); //send the message, check for errors if (!$mail->send()) { //Message not sent //echo "Mailer Error: " . $mail->ErrorInfo; $responce = array( 'message' => $mail->ErrorInfo, 'success' => FALSE, ); echo json_encode($responce); } else {//Message sent! $msg = "Well done $from_name, your message has been sent!\nWe will reply to the following email: $from" . "
Your Message: $body"; $responce = array( 'message' => $msg, 'success' => TRUE, ); echo json_encode($responce); } } 

像这样更改你的JS代码

 var form = $('#contact'); form.submit(function(event) { event.preventDefault(); var complete = $('#formAppend'); var $form = $(this); var name = $("#fname").val(); var email = $("#email").val(); var Message = $("#msg").val(); var countryoption = $("#country").val(); $.ajax({ type: 'POST', url: '../sendemail.php', data: { Name: name, Email: email, message: Message, Country: countryoption }, beforeSend: function() { complete.html('Message is Sending...').fadeIn(); } }) .done(function(data) { var response=JSON.parse(data); if(response.success == true) { //return true complete.html("Message Sent"); // if you want show Response message which get form sendemail.php complete.html(data.message); } else { //return false complete.html("Message Not Sent!"); // if you want show Response message which get form sendemail.php complete.html(data.message) } //This should change depending on the php if statement at the bottom. }); }); //end contact form

将PHP的结尾更改为：

 header("Content-type:application/json"); $message = "Well done ".$from_name.", your message has been sent!
We will reply to the following email:".$from."
Your Message: ".$body; if (!$mail->send()) { echo '{"error":"'.$mail->ErrorInfo.'"}'; } else { echo '{"success":"'.json_encode($message).'"}'; } 

然后你可以在.done执行此操作：

 .done(function(data) { if (data.error) { complete.html(data.error).addClass("error"); } else complete.html(JSON.parse(data.success)); } });
