我點擊提交後，爲什麼會從我的表單收到2封電子郵件

Question

我的表單有問題。當我點擊提交時，所有的細節都通過我的電子郵件發送，但問題是：我收到2封電子郵件，其中1封在我的收件箱中，一封在我的垃圾郵件中。

我真的不知道爲什麼我有什麼錯我的代碼..

任何建議將高度讚賞。

這裏是我的send_app.php

<?php 

// get posted data into local variables 
$EmailFrom = "webmaster"; 
$EmailTo = "sjb_jparedes@yahoo.com"; 
$Subject = "Contact us"; 
$name = $_POST['name']; 
$address=$_POST['address']; 
$month =$_POST['month']; 
$day =$_POST['day']; 
$year =$_POST['year']; 
$home =$_POST['home']; 
$mobile =$_POST['mobile']; 
$contact =$_POST['contact']; 
$relationship =$_POST['relationship']; 
$course =$_POST['course']; 
$hours =$_POST['hours']; 



// prepare email body text 
$Body = ""; 
$Body .= "Name: "; 
$Body .= $name; 
$Body .= "\n"; 
$Body .= "Address: "; 
$Body .= $address; 
$Body .= "\n"; 
$Body .= "Month: "; 
$Body .= $month; 
$Body .= "\n"; 
$Body .= "Day: "; 
$Body .= $day; 
$Body .= "\n"; 
$Body .= "Year: "; 
$Body .= $year; 
$Body .= "\n"; 
$Body .= "Home No.: "; 
$Body .= $home; 
$Body .= "\n"; 
$Body .= "Mobile: "; 
$Body .= $mobile; 
$Body .= "\n"; 
$Body .= "Contact Person: "; 
$Body .= $contact; 
$Body .= "\n"; 
$Body .= "Relationship: "; 
$Body .= $relationship; 
$Body .= "\n"; 
$Body .= "Course: "; 
$Body .= $course; 
$Body .= "\n"; 
$Body .= "Hours: "; 
$Body .= $hours; 
$Body .= "\n"; 

$headers = "From: ".$EmailFrom."" ; 

// send email 
$success = mail($EmailTo, $Subject, $Body, $headers); 

// redirect to success page 
if (mail($EmailTo, $Subject, $Body, $headers)){ 

header("Location: application.php"); 

} 
?> 

Answer 1

好代碼，你在你的代碼中調用mail兩次：

// send email 
$success = mail($EmailTo, $Subject, $Body, $headers); 

// redirect to success page 
if (mail($EmailTo, $Subject, $Body, $headers)){ 

所以當然郵件發送兩次...

Answer 2

您正在給郵件打兩次電話！與

if ($success){ 

Answer 3

答案很簡單替換此代碼

// redirect to success page 
if (mail($EmailTo, $Subject, $Body, $headers)){ 

：您發送2個電子郵件：

// First E-Mail 
$success = mail($EmailTo, $Subject, $Body, $headers); 

// Second E-Mail 
if (mail($EmailTo, $Subject, $Body, $headers)){ 
    header("Location: application.php"); 
} 

只要刪除第一行，或者 - 如果你需要的返回值 - 寫此：

// Send E-Mail 
$success = mail($EmailTo, $Subject, $Body, $headers); 

if ($success){ 
    header("Location: application.php"); 
} 

Answer 4

// redirect to success page 
if (mail($EmailTo, $Subject, $Body, $headers)){ 

這個條件實際執行另一個發送，如果成功，然後將執行

header("Location: application.php");
