Ich erhalte auf meiner Website leere E-Mails

Question

Ich baue ein HTML5-basiertes Kontaktformular mit PHP-Mail-Skript.

Ich weiß nicht, warum ich leere E-Mails bei der Einreichung erhalten, sowie wenn ich eine Nachricht wie "Vielen Dank für die Kontaktaufnahme mit uns" drucken möchte, wie würde ich das tun.

<?php 
$name = (isset($_POST['name']) ? $_POST['name'] : null); 
$phone = (isset($_POST['phone']) ? $_POST['phone'] : null); 
$address = (isset($_POST['address']) ? $_POST['address'] : null); 
$appointment_datepicker =(isset($_POST['appointment-datepicker']) ? $_POST['appointment-datepicker'] : null); 
$message = (isset($_POST['textarea']) ? $_POST['textarea'] : null); 
$email_address = (isset($_POST['email']) ? $_POST['email'] : null); 



// Create the email and send the message 
$to = 'dipen2512@gmail.com'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to. 
$email_subject = "Website Contact Form: $name"; 
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nPhone: $phone\n\nEmail: $email_address\n\nAppointment: $appointment_datepicker\n\nAddress: $address\n\nMessage:\n$message"; 
$headers = "From: noreply@dev-designers.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com. 
$headers .= "Reply-To: $email_address"; 
$mail_status = mail($to,$email_subject,$email_body,$headers); 

/** Check for empty fields 
if(!empty($_POST['name']) || !empty($_POST['phone']) || !empty($_POST['address']) || !empty($_POST['appointment-datepicker']) || !empty($_POST['textarea']) || filter_var($_POST['email'],FILTER_VALIDATE_EMAIL)) 
{**/ 
if ($mail_status) { ?> 
    <script language="javascript" type="text/javascript"> 
     print("Thank you for the message. We will contact you shortly."); 
     window.location = 'http://thankyou.html'; 
    </script> 
    <?php 
    } 

else { ?> 
    <script language="javascript" type="text/javascript"> 
     print('Message failed. Please, send an email to gordon@template-help.com'); 
     window.location = 'http://thankyou.html'; 
    </script> 
<?php 
} 
?>

Answer 1

Ihren Formulareingaben fehlen die Attribute "name". IDs werden nicht in einer Formularanforderung weitergeleitet. nur die Name-Wert-Paarungen.

    v---------v 
<input id="name" name="name" type="text" class="form-control" required="required">
