Question

<div id="formwrap">
    <form method="post" id="submitform" action="submitemail.php" >
        <input type="text" class="formstyle" title="Name" name="name" />

        <textarea name="message" title="Message"></textarea>
        <input class="formstyletwo" type="submit" value="Send">  
    </form>

PHP

<?php
    $mailto = "abcd@gmail.com"; /*PUT YOUR EMAIL IN HERE*/
    $cc = "";
    $bcc = "";
    $subject = "enquiry";
    $vname = "Website Contact Form";
    $email = $_POST['email'];
    function validateEmail($email){
        if(eregi('^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+\.[a-zA-Z]{2,4}(\.[a-zA-Z]{2,3})?(\.[a-zA-Z]{2,3})?$', $email)) return true;
        else return false;
    }
    if(strlen($_POST['name']) < 1  || strlen($_POST['message']) < 1 || validateEmail($email) == FALSE){
        if(empty($_POST['name'])){
            $emailerror .= '<li>Enter name</li>';
        }
        if(validateEmail($email) == FALSE){
            $emailerror .= '<li>Enter valid email</li>';
        }
        if(empty($_POST['message'])){
            $emailerror .= '<li>Enter message</li>';
        }
    }
    else{
        $emailerror .= "Your email has been sent successfully";
        // NOW SEND THE ENQUIRY
        $timestamp = date("F j, Y, g:ia");
        $messageproper ="\n\n" .
            "Name: " .ucwords($_POST['name']) ."\n" .
            "Email: " .ucwords($email) ."\n" .
            "Comments: " .$_POST['message'] ."\n" .
            "\n\n" ;
            $messageproper = trim(stripslashes($messageproper));
            mail($mailto, $subject, $messageproper, "From: \"$vname\" <".$_POST['e_mail'].">\nReply-To: \"".ucwords($_POST['first_name'])."\" <".$_POST['e_mail'].">\nX-Mailer: PHP/" . phpversion() );
    }
?>

<div id='emailerror'>
    <ul>
        <? echo $emailerror; ?>
    </ul>
</div>

在 XAMPP 服务器上运行它时，我在发送按钮下方以文本形式得到错误的输出

显示错误输出

输入姓名'; } if(validateEmail($email) == FALSE) { $emailerror .= ' 输入有效的邮箱 '; } if(empty($_POST['message'])) { $emailerror .= ' 输入消息'; } } else { $emailerror .= "您的邮件已发送 成功"; // 现在发送查询 $timestamp = date("F j, Y, g:ia"); $messageproper ="\n\n" . "名称：" . ucwords($_POST['name']) . “\n”。 “电子邮件： ” 。 ucwords($email) 。 “\n”。 “注释： ” 。 $_POST['消息'] 。 “\n”。 "\n\n" ; $messageproper = 修剪（stripslashes（$messageproper））；邮件（$mailto，$主题， $messageproper, "发件人：\"$vname\" \n回复： \"".ucwords($_POST['first_name'])."\" \nX-Mailer: PHP/" . phpversion() ); } ?>

Answer 1

而不是使用短标签 php <? ?> user <?php ?> 它应该修复它。

另请注意：从本地您不能发送电子邮件 throw mail 函数，并且不推荐使用 eregi 函数，而使用 preg_match 代替它

preg_match('%^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+\.[a-zA-Z]{2,4}(\.[a-zA-Z]{2,3})?(\.[a-zA-Z]{2,3})?$%', $email)

Answer 2

好的，这应该可以工作

<?php
$mailto = "abcd@gmail.com"; /*PUT YOUR EMAIL IN HERE*/
$cc = "";
$bcc = "";
$subject = "enquiry";
$vname = "Website Contact Form";


$errors = array();
if($_POST){

    if(!isset($_POST['name']) || $_POST['name'] == "")
        $errors[] = "Please enter your name.";

    if(isset($_POST['email']) && $_POST['email'] != ""){
        if(!preg_match('%^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+\.[a-zA-Z]{2,4}(\.[a-zA-Z]{2,3})?(\.[a-zA-Z]{2,3})?$%', $_POST['email']))
            $errors[] = "Not valid email";
    }else
        $errors[] = "Please enter your email";

    if(!isset($_POST['message']) || $_POST['message'] =="" ){
        $errors[] = "Please enter the message.";
    }

    if(!$errors){
        //send here your email...
        echo "email sended";
    }
}



?>
 <div id='emailerror'>
    <ul>
        <?php 
            foreach($errors as $err){
                echo "<li>$err</li>";
            }
        ?>
    </ul>
</div>

Answer 3

如前所述，使用完整标签。此外，您应该在附加到它之前声明您的 $emailerror 变量：

$emailerror = "";

在代码的开头。
