提问于

我正在使用我的网站的联系表单，我验证然后通过电子邮件发送给自己，验证工作正常，如果用户第一次正确输入所有详细信息，它会通过电子邮件发送给我 . 但是，如果用户输入不正确的数据，然后更正它并再次点击发送，它将不会发送电子邮件，下面是我到目前为止的表单和PHP代码 .

联系表单的HTML代码

<form action="contact.php" method="post">
<fieldset>

<label for="name">Name:<span class="star">*</span></label> 

<input type="text" name="name" id="name" placeholder="Enter your name" maxlength="50" required />
<label for="email">Email:<span class="star">*</span></label> 

<input type="email" name="email" id="email" placeholder="Enter your email address" maxlength="100" required />
<label for="number">Telephone: </label><input type="tel" name="number" id="number" placeholder="Enter your phone number" maxlength="12" />
<label for="message">Message:<span class="star">*</span></label>
<textarea name="message" id="message" placeholder="Enter your message" cols="54" rows="5" required></textarea>

<p class="small"><span class="star">*</span>&nbsp; Denotes a required field </p>

<input type="submit" id="send" name="send" value="Send" />

</fieldset>
</form>

用于发送表单的PHP代码

function fix_string($var)
{
    if(get_magic_quotes_gpc()) $var = stripslashes($var);
    $var = strip_tags($var);
    return $var;
}

{
    $details = array('name' => fix_string($_POST['name']),
            'email' => fix_string($_POST['email']),
            'number' => fix_string($_POST['number']),
            'message' => fix_string($_POST['message']));
}

$send = $_POST['send'];
$message = "";

 foreach ($details as $field => $detail)
    $message .= $field . ": " . $detail . "
";

$to = "smokey.12345@hotmail.co.uk";
$subject = "Website contact form";
$message = wordwrap($message, 70, "/r/n");
$headers = "From ". $details['email'];

function trim_value(&$value)
{
    $value = trim($value);
}

array_walk($details, 'trim_value');

if ($send)
{
    foreach ($details as $field => $detail)
    {
        if (empty($detail) && $field!='number')
            echo "<p class='error'>Please fill in the required field: " . ucfirst($field) . "
</p>";

    }
}
else
{
    mail($to, $subject, $message, $headers);
    echo "<p class='success'>Mail was sent successfully</p>";
}

    为了使代码在同一页面上工作，您需要将操作设置为 action=""

    否则，您需要使用两页 . 一个用于表单，另一个用于 contact.php ，这是您的处理程序 . 我建议你使用两个页面，但这里有一个可以在一个页面内工作的版本 .

    <?php

if(isset($_POST['send'])) {

function fix_string($var)
{
    if(get_magic_quotes_gpc()) $var = stripslashes($var);
    $var = strip_tags($var);
    return $var;
}

    $details = array('name' => fix_string($_POST['name']),
            'email' => fix_string($_POST['email']),
            'number' => fix_string($_POST['number']),
            'message' => fix_string($_POST['message']));

function trim_value(&$value)
{
    $value = trim($value);
}

array_walk($details, 'trim_value');

    foreach ($details as $field => $detail)

    {
        if (empty($detail) && $field!='number')

            die("<p class='error'>Please fill in the required field: " . ucfirst($field) . "
    </p>");

    }

$message = "";
 foreach ($details as $field => $detail)
    $message .= $field . ": " . $detail . "\n";

$send = $_POST['send'];
$email = $_POST['email'];

$to = "smokey.12345@hotmail.co.uk";
$subject = "Website contact form";

$headers = "From: $email" . "\r\n" .
"Reply-To: $email" . "\r\n" .
"X-Mailer: PHP/" . phpversion();

    mail($to, $subject, $message, $headers);
    echo "<p class='success'>Mail was sent successfully</p>";


exit;

} // closing brace for if(isset($_POST['send'])) {

?>

<!DOCTYPE html>

<title></title>

<label for="name">Name:<span class="star">*</span></label> 
    
<input type="text" name="name" id="name" placeholder="Enter your name" maxlength="50"  />
<label for="email">Email:<span class="star">*</span></label> 
    
<input type="email" name="email" id="email" placeholder="Enter your email address" maxlength="100"  />

<p class="small"><span class="star">*</span>&nbsp; Denotes a required field </p>

<input type="submit" id="send" name="send" value="Send" />

</body>
</html>

    原始答案

    此行格式不正确 .

    $message = wordwrap($message, 70, "/r/n");

    将其更改为：

    $message = wordwrap($message, 70, "\r\n");

    您需要使用 \ 而不是 /

    我可以让你的表单工作的唯一方法是添加一个 die 函数 .

    立即尝试：

    <?php

function fix_string($var)
{
    if(get_magic_quotes_gpc()) $var = stripslashes($var);
    $var = strip_tags($var);
    return $var;
}

    $details = array('name' => fix_string($_POST['name']),
            'email' => fix_string($_POST['email']),
            'number' => fix_string($_POST['number']),
            'message' => fix_string($_POST['message']));

function trim_value(&$value)
{
    $value = trim($value);
}

array_walk($details, 'trim_value');

    foreach ($details as $field => $detail)

    {
        if (empty($detail) && $field!='number')

            die("<p class='error'>Please fill in the required field: " . ucfirst($field) . "
    </p>");

    }

$message = "";
 foreach ($details as $field => $detail)
    $message .= $field . ": " . $detail . "\n";

$send = $_POST['send'];
$email = $_POST['email'];

$to = "smokey.12345@hotmail.co.uk";
$subject = "Website contact form";

$headers = "From: $email" . "\r\n" .
"Reply-To: $email" . "\r\n" .
"X-Mailer: PHP/" . phpversion();

    mail($to, $subject, $message, $headers);
    echo "<p class='success'>Mail was sent successfully</p>";


exit;

?>
