我的联系表在查看页面时发送空白电子邮件

Question

每次我访问该页面时，我的联系表单都会发送黑色电子邮件，并且每当有人填写表单并单击发送时都会发送另一封电子邮件。我正在尝试学习如何验证我的联系表格的数据，并且一整天都没有运气。到目前为止，我对 php 或 javascript 代码知之甚少，但已经从以前编写的代码中尽力而为。

我尝试使用此http://www.inmotionhosting.com/support/edu/website-design/using-php-and-mysql/how-to-create-a-custom-php-contact-form 来帮助编写代码。

有什么想法吗？

<form action="" method="post" style="width:100%;">
    Name*<br> <input type="text" name="name" style="width:50%;" ><br/><br/>
    Email*<br> <input type="text" name="email" style="width:50%;"> <br/><br/>
Phone*<br> <input type="text" name="phone" style="width:50%"> <br/><br/>
    <input name="submitted" type="submit" value="Send" >
    <input name="" type="reset" value"Reset">
</form>


<?php 
if (isset($_REQUEST['submitted'])) {
    // Initialize error array.
    $errors = array();
    // Check for a name
    if (!empty($_REQUEST['name'])) {
        $name = $_REQUEST['name'];
        $pattern = "/^[a-zA-Z0-9\_]{2,20}/";]
        if (preg_match($pattern,$name)) {
            $name = $_REQUEST['name'];
        } else { 
            $errors[] = 'Your Name can only contain _, 1-9, A-Z or a-z 2-20 long.';
        }
    } else {
        $errors[] = 'You forgot to enter your name.';
    }

    //Check for a valid phone number
    if (!empty($_REQUEST['phone'])) {
        $phone = $_REQUEST['phone'];
        $pattern = "/^[0-9\_]{7,20}/";
        if (preg_match($pattern,$phone)) {
            $phone = $_REQUEST['phone'];
        } else {
            $errors[] = 'Your phone number can only be numbers.';
        }
    } else {
        $errors[] = 'You forgot to enter your phone number.';
    }

    //Check for a valid email
    if (!filter_var($_REQUEST['email'], FILTER_VALIDATE_EMAIL)) {
        $errors[] = 'The email provided is not valid.';
    }
} else {
    $email = $_REQUEST['email'];
}


//End of validation 
if (empty($errors)) { 
    $from = "From: " . $_REQUEST['email'];
    $to = "myemail@myemail.com"; 
    $subject = "A comment from " . $name . "";

    $message = "Message from " . $name . "
        Phone: " . $phone . "
        Email: " . $_REQUEST['email'] . "";
    mail($to,$subject,$message, $from);
} 

//Print Errors
if (isset($_REQUEST['submitted'])) {
    // Print any error messages. 
    if (!empty($errors)) { 
        echo '<hr /><h3 >The following occurred:</h3><ul>'; 
        // Print each error. 
        foreach ($errors as $msg) { 
            echo '<li>'. $msg . '</li>';
        }
        echo '</ul><h3 >Your mail could not be sent due to input errors.</h3><hr />';
    } else {
        echo '<hr /><h3 align="center" >Your mail was sent. Thank you!</h3><hr /><p>Below is the message that you sent.</p>'; 
        echo "Message from " . $name . "<br />Phone: ".$phone."<br />Email:" . $email;
    }
}
//End of errors array
?>

Answer 1

您正在if (isset($_POST['submitted'])) 块之外发送邮件。我认为问题在于您在这里有一个额外的大括号：

    //Check for a valid email
    if (!filter_var($_REQUEST['email'], FILTER_VALIDATE_EMAIL)) {
        $errors[] = 'The email provided is not valid.';
    } // <<===== HERE
} else {
    $email = $_REQUEST['email'];
}

因此，else 子句未连接到电子邮件验证，而是连接到 if (isset($_POST['submitted']))。因此，当表单尚未提交时，您设置$email，然后进入发送电子邮件的代码。

尚未声明的数组仍为空。

改变

if (empty($errors)) { 

到

if (isset($errors) && empty($errors)) {
