PHP联系表格修复

Question

I have a PHP Contact form that was working correctly, but i made some changes to the some variables and it stopped working.

This is the PHP code below:

<?php

$action = $_SERVER['PHP_SELF'];

    $name = $_POST['name'];
    $position = $_POST['position'];
    $school = $_POST['school'];
    $address = $_POST['address'];
    $city = $_POST['city'];
    $state = $_POST['state'];
    $zip = $_POST['zip'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $model = $_POST['model'];
    $comments = $_POST['comments'];

$to = 'jasmeet0921@gmail.com';
$subject = '30 Day Evaluation Request -'.$name;
$body = 'Name: ' . $name .  "\n" .  
'Title/Position: ' . $position .  "\n" . 
'School: ' . $school .  "\n" .
'Address: ' . $address .  "\n" .  
'City: '. $city .  "\n" . 
'State: ' . $state .  "\n" . 
'Zip Code: ' . $zip .  "\n" . 
'Email: ' . $email .  "\n" .
'Phone Number: '. $phone .  "\n" . 
'Model To Evaluate: ' . $model .  "\n" . 
'Comments: ' . $comments .  "\n" . 

$headers = 'From: Sales <seorick1904@gmail.com>';
$thankyou = "thankyou.html"; // thank you page
if(isset($_POST['name']) && isset($_POST['school']) && isset($_POST['address']) && isset($_POST['city']) && isset($_POST['state']) && isset($_POST['zip']) && isset($_POST['email']) && isset($_POST['phone'])&& isset($_POST['model'])&& isset($_POST['comments']))
{
    $name = $_POST['name'];
    $position = $_POST['position'];
    $school = $_POST['school'];
    $address = $_POST['address'];
    $city = $_POST['city'];
    $state = $_POST['state'];
    $zip = $_POST['zip'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $model = $_POST['model'];
    $comments = $_POST['comments'];

    if(empty($phone) || empty($comments) || empty($name) || empty($position) || empty($school) || empty($address) || empty($city) || empty($state) || empty($zip) || empty($email) || empty($model)){
        echo 'Fields With * Sign Are Mandatory';
    }
    else{
        if(mail($to,$subject,$body,$headers)){
            echo "<div class='message'>" . $a = 'Your message has been successfully sent!' . "</div>";
            $name = "";
            $position = "";
            $school = "";
            $address = "";
            $city = "";
            $state = "";
            $zip = "";
            $email = "";
            $phone = "";
            $model = "";
            $comments = "";
        }
        else{
            echo 'There was an error sending email/s.';
        }
    }

}


?>

This is the HTML code:

                        <!--Label-->

                         <textarea name="comments" class="textarea" style="overflow:hidden;" rows="" cols="" ><?php echo $comments; ?></textarea>
                    </div><!--Row-->

                    <input type="submit" class="submit" value="" />
                    <p><?php echo $a ?></p>
                    </form>

Whenever i click on submit i get "There is some error /s sending email".

The last else runs that is in the PHP code.

All fields are mandatory.

Answer 1

One problem I can see:

'Comments: ' . $comments .  "\n" . 

The old missing semicolon.
