验证的php联系表中的代码错误发送邮件[重复]

Question

我编写了一个联系我们页面并验证它我想要的是当用户单击发送按钮时信息应该首先验证然后发送一封电子邮件到给定的硬编码电子邮件地址我面临一个问题不知道为什么我的编码是不工作，验证很好，但是当我点击提交按钮时，它没有显示任何关于电子邮件的成功消息，也没有发送电子邮件。请帮忙，这是我的代码：

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

                        <label>Your Name: * </label>
                        <span style="color:#F00;" class="error"><?php echo $nameErr;?></span>
                        <input type="text" name="name" placeholder="Noman" width="100px;">

                        <label>Email Id: * </label>
                        <span style="color:#F00;" class="error"><?php echo $emailErr;?></span>
                        <input type="text" name="email" placeholder="yourname@gmail.com">

                        <label>Contact Number (Optional): </label>
                        <span style="color:#F00;" class="error"><?php echo $contactErr;?></span>
                        <input type="text" name="contact" placeholder="0312-1234567">

                        <label>  Website URL (Optional):</label>
                        <span style="color:#F00;" class="error"><?php echo $websiteErr;?></span>
                        <input type="text" name="website" placeholder="www.yoursite.com">

                        <label>  Message: * </label>
                        <span style="color:#F00;" class="error"><?php echo $messageErr;?></span>
                        <textarea name="message" rows="10" cols="10" placeholder="Message"></textarea>

                        <input type="submit" name="submit" value="Submit" id="submit">      
                    </form> 

这是我的php代码

                        ?>

我认为这是标题问题，

这只是一个例子，改变值......

$header = "From: info@".$_SERVER["SERVER_NAME"]."\n";
$header .= "Content-Type: text/html; charset=utf-8\n";
$recipient = "abc@gmail.com"
$subject = $_POST['subject'];

    $body='<table width="90%" border="0">
    <tr>
    <td><b>Name:</b></td> <td>'.$name.'</td>
    </tr>
    <tr>
    <td><b>Email:</b></td> <td>'.$email.'</td>
    </tr>
    <tr>
    <td><b>Message:</b></td> <td>'.$message.'</td>
    </tr>
    <tr></table>';

    $res=@mail($recipient,$subject,$body,$header)

;
