PHP Error: all fields are required

Question

I am new to PHP (took some classes in college but its been a long time) and I keep getting this error when I submit my form Im not sure where the error is coming from and its driving me crazy! The error says: Error: all fields are required. This pops up when all the form fields have been filled out. Thank you to anyone that can help!

Here is my HTML: {

            <section id="book-appointment" class="book-appointment gray" style="padding-top: 100px">
                <div class="grid-container grid-container-padded shadow radius">
                    <div class="grid-x">

                            </form>
                        </div>
                    </div>      
                </div>
            </section><!-- /.book-appointment -->

}

And here is my PHP:

<?php 
$errors = '';
$myemail = 'email@hotmail.com';//
if(empty($_GET['firstname'])  || 
empty($_GET['email']) || 
empty($_GET['field_message']))
{
$errors .= "\n Error: all fields are required";
}

$firstname = $_GET['firstname']; 
$lastname= $_GET ['lastname'];
$email = $_GET['email']; 
$orgname = $_GET['orgname'];
$board = $_GET['board'];
$info = $_GET ['info'];
$budget = $_GET ['budget'];
$field_message = $_GET ['field_message'];


if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", 
$email))
{
$errors .= "\n Error: Invalid email address";
}

if( empty($errors))
{
$to = $myemail; 
$email_subject = "Form submission: $firstname $lastname";
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $firstname \n Last Name: $lastname \n Email: 
$email \n Organization Name: $orgname \n Board: $board \n Organization Info: 
$info \n Budget: $budget \n Message \n $field_message"; 

$headers = "From: $myemail\n"; 
$headers .= "Reply-To: $email";

mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
include ('Location: contact-form-thank-you.html');
} 
?>

Answer 1

You have some misnamed variables here (should be $_GET because your form defaults to that method and there are no form fields named 'name' or 'message'), so your error is coming from this block of code:

if(empty($_POST['name'])  || 
    empty($_POST['email']) || 
    empty($_POST['message']))
{
$errors .= "\n Error: all fields are required";
}

I strongly suspect you want the following fields:

if(empty($_GET['firstname'])  || 
    empty($_GET['email']) || 
    empty($_GET['field_message']))
{
$errors .= "\n Error: all fields are required";
}

Your form has no method specified, so it defaults to GET. This means all of your variables will be in the $_GET array, not $_POST

$firstname = $_GET['firstname']; 
$lastname= $_GET ['lastname'];
$email = $_GET['email']; 
$orgname = $_GET['orgname'];
$board = $_GET['board'];
$info = $_GET ['info'];
$budget = $_GET ['budget'];
$field_message = $_GET ['field_message'];

You can also simplify the following block of code, instead of using complex and possibly inaccurate regex:

if (!filter_var($email, FILTER_VALIDATE_EMAIL))
{
$errors .= "\n Error: Invalid email address";
}

这不是您在帖子数据中查看的 php 问题，因此您的表单需要在帖子中提交数据。

<form method="post" data-abide novalidate>
