我的聯繫表單有什麼問題？

Question

我做了一個簡單的聯繫表單，只是爲了練習，但由於某種原因它不起作用。這裏是我的代碼：

<?php 
if($_SERVER['REQUEST_METHOD'] == "POST") { 

$required = array('name', 'email', 'onderwerp', 'bericht'); 

$error = false; 
foreach($required as $field) { 
    if (empty($_POST[$field])) { 
    $error = true; 
    } 
    } 

if ($error) { 
    echo "All fields are required!"; 
} else { 
    $to = 'example@example.com'; 
    $datum = date("d-m-Y H:i"); 
    $ip = $_SERVER['REMOTE_ADDR']; 
    $naam = $_POST['name']; 
    $email = $_POST['email']; 
    $from = $_POST['email']; 
    $onderwerp = $_POST['onderwerp']; 
    $bericht = $_POST['bericht']; 
    $subject = "New e-mail!: $onderwerp"; 
    $message .= $bericht . "\n\n"; 
    $message .= "-----------------------------\n"; 
    $message .= "From:: " . $name . " (" . $_POST['email'] . ")\n"; 
    $message .= "IP-adres: " . $ip . "\n"; 
    $message .= "Sent on $datum \n"; 
    $headers = 'From: '.$_POST['email']; 

$sent_email = mail($to, $subject, $message, $headers); 
if (!$sent_email) { 
echo "Mail has been sent!"; 
} 
else 
{ 
echo "Woops!"; 
} 

} 

} 
else { 
// Form has not been submitted 
} 

所以結果是Woops！但我想不出爲什麼事先不工作:( 謝謝！

Answer 1

你被錯誤檢查if聲明。[其實郵件在你的情況下發送]你的代碼是。

if ($sent_email) { // I have modified here 
echo "Mail has been sent!"; 
} 
else 
{ 
echo "Woops!"; 
} 

Answer 2

你的邏輯是落後的。成功mail()返回true。但你治療，真正的失敗。如果要

if ($sent_email === TRUE) { 
    success ... 
} else { 
    failure ... 
}
