郵件功能不起作用....我無法得到原因

Question

我做了一個PHP腳本發送郵件.....但我只收到一個「ERROR」消息，這是在else條件.. 。和我無法獲得郵件.....這意味着我的郵件功能不起作用...

可能是什麼問題？

$name=$_POST['name']; 
$email=$_POST['email']; 
$phone=$_POST['phone']; 
$comments=$_POST['comments']; 
$verify=$_POST['verify']; 

if(trim($name) == '') { 
echo '<div class="error_message">Attention! You must enter your name.</div>'; 
exit(); 
} else if(trim($email) == '') { 
echo '<div class="error_message">Attention! Please enter a valid email address.</div>'; 
exit(); 
} else if(trim($phone) == '') { 
echo '<div class="error_message">Attention! Please enter a valid phone number.</div>'; 
exit(); 
} else if(!is_numeric($phone)) { 
echo '<div class="error_message">Attention! Phone number can only contain digits.</div>'; 
exit(); 
} else if(!isEmail($email)) { 
echo '<div class="error_message">Attention! You have enter an invalid e-mail address, try again.</div>'; 
exit(); 
} 
if(!isset($verify) || trim($verify) == '') { 
echo '<div class="error_message">Attention! Please enter the verification number.</div>'; 
exit(); 
} else if(trim($verify) != '4') { 
echo '<div class="error_message">Attention! The verification number you entered is incorrect.</div>'; 
exit(); 
} 
if(get_magic_quotes_gpc()) { 
$comments = stripslashes($comments); 
} 


$to="contact@yoursite.com"; 

$subject='Inquiry'; 

$message='Name : '.$name."<br />".'Email : '.$email."<br />".'Mobile : '.$phone."<br />".'Message : '.$comments; 

$headers = "MIME-Version: 1.0\r\n"; 
$headers .= "Content-type: text/html; charset=utf-8\r\n"; 
$headers .= "From: ".$email."\r\n"; 
$headers .= "Reply-To: ".$email."\r\n"; 
$headers .= "X-Mailer: PHP/".phpversion(); 

$mail=mail($to, $subject, $message, $headers); 

if($mail) { 
echo "<fieldset>"; 
echo "<div id='success_page'>"; 
echo "<h4>Email Sent Successfully</h4>"; 
echo "<p>Thank you $name, your message has been submitted to us.</p>"; 
echo "</div>"; 
echo "</fieldset>"; 
} 
else { 
echo "ERROR"; 
} 

Answer 1

這是我假設的問題。

if(!isEmail($email)) {} 

IsEmail是不是一個fundstion，除非你的意思是is_email，我認爲是wordpress？ 或一個我知道的，但你可以使用filter_var與filter_email

這將工作太

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { //Return True Is Valid 
echo "HEY IM VALID"; 
} 

另外我想重做的if語句在某種程度上這樣

foreach ($_POST as $item => $value){ 
    if($value === ""){ echo $item." must be a valid input"; exit();} 
}

似乎郵件函數返回false。郵件功能總是返回true或false。所以你不能很容易地發現，如果郵件沒有工作，很容易出錯。它可能是SMTP錯誤，連接錯誤或任何東西。有可能性的數量在那裏。 have a look at this link
