找不到错误PHP

Question

所以，这是我第一次尝试 PHP，所以它可能很容易修复。我正在尝试制作一个可以提交并发送到管理电子邮件的表单。

我正在使用 MAMP 运行服务器，在线填写表单并提交，但出现错误：

We are very sorry, but there were error(s) found with the form you submitted. These errors appear below.

We are sorry, but there appears to be a problem with the form you submitted.

Please go back and fix these errors.

完整的 PHP 代码：

<?php
if(isset($_POST['email'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "I HAVE CORRECT EMAIL HERE 4 SURE";
    $email_subject = "eShop Contact Form";

    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }


    // validation expected data exists
    if(!isset($_POST['fname']) ||
        !isset($_POST['lname']) ||
        !isset($_POST['email']) ||
        !isset($_POST['subject'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');
    }



    $first_name = $_POST['fname']; // required
    $last_name = $_POST['lname']; // required
    $email_from = $_POST['email']; // required
    //$country = $_POST['country']; // not required
    $comments = $_POST['subject']; // required

    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

    if(!preg_match($email_exp,$email_from)) {
        $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
    }

    $string_exp = "/^[A-Za-z .'-]+$/";

    if(!preg_match($string_exp,$first_name)) {
        $error_message .= 'The First Name you entered does not appear to be valid.<br />';
    }

    if(!preg_match($string_exp,$last_name)) {
        $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
    }

    if(strlen($comments) < 2) {
        $error_message .= 'The Comments you entered do not appear to be valid.<br />';
    }

    if(strlen($error_message) > 0) {
        died($error_message);
    }

    $email_message = "Form details below.\n\n";


    function clean_string($string) {
        $bad = array("content-type","bcc:","to:","cc:","href");
        return str_replace($bad,"",$string);
    }



    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
//    $email_message .= "Country: ".clean_string($country)."\n";
    $email_message .= "Subject: ".clean_string($comments)."\n";

// create email headers
    $headers = 'From: '.$email_from."\r\n".
        'Reply-To: '.$email_from."\r\n" .
        'X-Mailer: PHP/' . phpversion();
    @mail($email_to, $email_subject, $email_message, $headers);
    ?>

    <!-- include your own success html here -->

    Thank you for contacting us. We will be in touch with you very soon.

    <?php

}
?>

这是应该有问题的部分：

    // validation expected data exists
    if(!isset($_POST['fname']) ||
        !isset($_POST['lname']) ||
        !isset($_POST['email']) ||
        !isset($_POST['subject'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');
    }

P.S 我在这里复制了http://www.freecontactform.com/email_form.php 的代码并稍作修改。

好吧，现在我将从这里开始。 我会重新编辑你的代码

SUBMIT.PHP

<?php
if(isset($_POST['formid'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "yourmail.com.id@maisetting.com";
$email_subject = "eShop Contact Form";
//
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$mail = $_POST['email'];
$subject = $_POST['subject'];
$comments = $_POST['comm'];
// I was replace this line
// validation expected data exists
if(empty($fname) or empty($lname) or empty($mail) or empty($subject) or empty($comments)){
$err_msg = 'We are sorry, but there appears to be a problem with the form you submitted.';
} else {
// check mail registered
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$mail)) {
$err_msg = 'The Email Address you entered does not appear to be valid.<br />';
} else {
// check name
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$fname)) {
$err_msg = 'The First Name you entered does not appear to be valid.<br />';
} else {
// check Last name
if(!preg_match($string_exp,$lname)) {
$err_msg = 'The Last Name you entered does not appear to be valid.<br />';
} else {
// Check comment
if($comments<2 or $comments=='') {
$err_msg = 'The Comments you entered do not appear to be valid.<br />';
} else {
// SEND msg from the visitor
$err_msg = 'Your Messages Was Send. ThankYou!';
$email_message = "Form details below.\n\n";

function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}

$email_message .= "First Name: ".clean_string($fname)."\n";
$email_message .= "Last Name: ".clean_string($lname)."\n";
$email_message .= "Email: ".clean_string($email)."\n";
//    $email_message .= "Country: ".clean_string($country)."\n";
$email_message .= "Subject: ".clean_string($comments)."\n";

// create email headers
$headers = 'From: '.$email."\r\n".
'Reply-To: '.$email."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);

}}}}} } else { $err_msg = 'Add Your comment here'; }
?>

INDEX.PHP

<?php require('SUBMIT.PHP'); ?>
<form action="#" method="post" />
<p><label>First Name</label>
<input type="text" placeholder="First name here" name="fname" />
</p>
<p><label>Last Name</label>
<input type="text" placeholder="Last name here" name="lname" />
</p>
<p><label>Mail</label>
<input type="text" placeholder="Add yourmail here" name="mail" />
</p>
<p><label>Subject</label>
<input type="text" placeholder="Subject here" name="subject" />
</p>
<p><label>Your Comment</label>
<textarea name="comm"></textarea>
</p>
<p><input type="submit" name="formid" value="Send"  /></p>
</form>
<?php echo $err_msg; ?>

现在，开始测试。
