Ajax調用PHP成功觸發錯誤

Question

我打電話給PHP函數發送一封包含表單信息的電子郵件，電子郵件正在成功發送和接收，當我調試PHP函數時，它返回TRUE。問題在於AJAX調用正在捕獲[object Object]錯誤，並在AJAX調用中的錯誤部分中觸發該函數，而不是成功調用該函數。有誰知道這可能是什麼原因造成的？

這裏是我的Java Script代碼：

<script type="text/javascript"> 
$("#candidate_form").submit(function(){ 


$.ajax({ 
    type: "POST", 
    url: "php/mail.php", 
    data: { fname: $("#fname").val(), lname: $("#lname").val(), email: $("#email").val(), phone: $("#phone").val()}, 
    dataType: "json", 
    success: function(response){ 
     alert(response) 
     $("#jobModal").show(); 
    }, 
    error: function(response){ 
     alert("This action failed with the following error" + response); 
    } 
    }) 
    .done(function(data) { 
    $("#jobModal").modal("show"); 
    }) 


}); 

</script> 

這是我的PHP代碼：

所有的

<?php 


if (isset($_POST)) { 
sendCandidate(); 
} 

function sendCandidate() { 

$emailTo="mail@gmail.com"; 
$subject="Candidate Info Submited from Website"; 
$body= "Hello!

Name: ". $_POST['fname']. " ". $_POST['lname']. 
" 
Email: ".$_POST['email']. 
" 
Phone: ". $_POST['phone']. 
"

", $headers); 





return json_encode($candidateMailSent); 
} 



?>

首先，當你做一個json_encode，它需要一個陣列上進行。 Mail會返回一個布爾值，您將其分配給$candidateMailSent。你應該把它分配給$candidateSentMail['success']

在php文件中它表示返回值是true或false。我沒有看到它回覆了一條消息。

然後在jQuery的方面，你將考驗響應，responce.success

前，

success: function(response.success){ 
     alert(response.success) 
     $("#jobModal").show(); 
    }, 
    error: function(response.success){ 
     alert("This action failed with the following error" + response.success); 
    }
