PHP error on all fields required - but all fields are inserted - php

Question

I'm making a signup form (signup.html) with a php handler (signup-form-handler.php).
But it seems like I'm doing something wrong.
This is my code:
$errors = '';
$myemail = 'example#domain.com';//<-----Put Your email address here.
if(empty($_POST['FirstName']) ||
empty($_POST['LastName']) ||
empty($_POST['City']) ||
empty($_POST['Country']))
{
$errors .= "\n Error: all fields are required";
}
$FirstName = $_POST['FirstName'];
$LastName = $_POST['LastName'];
$City = $_POST['City'];
$Country = $_POST['Country'];
$Int1 = $_POST['Int1']; // <---- Here's what seems to be the issue
$Int2 = $_POST['Int2']; // <---- Here's what seems to be the issue
if( empty($errors))
{
$to = $myemail;
$email_subject = "Udfyldelse af test på Gamification: $FirstName";
$email_body = "Du har fået en ny besvarelse. ".
"Her er besvarelserne:\n Fornavn: $FirstName \n Efternavn: $LastName \n By: $City \n Land $Country \n".
"De fire personlige interesser: $Int1 og $Int2";
$headers = "From: $myemail\n";
mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
}
Here's the relevant html code:
<form id="contact_form" name="contact_form" action="signup-form-handler.php">
<!-- Personlige oplysninger -->
<div class="next">
<h3>Personlige oplysninger<a class="info" href="#" title="Testing"><img style="height: 15px; width: 15px; margin-left: 5px;" alt="Time" src="img/signup_form/info_simple.png"></a></h3>
<b>Mit navn er</b>
<input class="user_field" placeholder="fornavn" id="FirstName" name="FirstName" type="text" maxlength="60" />
<input class="user_field" placeholder="efternavn" id="LastName" name="LastName" type="text" maxlength="60" />
</br>
<b>og bor i</b>
<input class="user_field" placeholder="indsæt by" id="City" name="City" type="text" maxlength="60" />
<b>,</b>
<input class="user_field" placeholder="indsæt land" id="Country" name="Country" type="text" maxlength="60" />
</br>
</br>
<b>Beskriv dig selv med 4 interesser</b>
</br>
<input id="Int1" name="Int1" class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 1" />
<input id="Int2" name="Int2" class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 2" />
<input class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 3" />
<input class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 4" />
</div>
As you can see from my code example, I'm trying to get input from my an html form. I've commented in to the code, where the problem occurs. If I retrieve input from Int1 and Int2, I get the answer, that all required fields need to be filled in, but I don't want to require Int1 and Int2. Also I didn't add Int1 and Int2 in the beginning where I check if the other variables are empty.
If I remove Int1 and Int2 it all works fine.
When I send the form after inserting all the inputs, I get the following message:
"Error: all fields are required"
What am I doing wrong?
Hope I gave enough info to find the issue, thanks!

Answer 1

The default method is GET. Set your form method to POST:
<form id="contact_form" name="contact_form" action="signup-form-handler.php" method="POST">
So basically you're not passing the values to the script. If you wanted to use the GET method, switch all instances of $_POST to $_GET and you can leave your form as is.

Answer 2

In the inputs Int1 and Int2 the attribute type is missing.

Answer 3

ok, for starters, the "< b >" for bold tag is depricated, use "< strong > < /strong > "
if you add this to your php page it works, play about with the form though as i couldnt understand the danish to know what was what. this is a one page solution, no need for a HTML file
<?php
$form = '<form id="contact_form" name="contact_form" action="'.$_SERVER['PHP_SELF'].'" method="post" >
<!-- Personlige oplysninger -->
<h3>Personlige oplysninger<a class="info" href="#" title="Testing"><img style="height: 15px; width: 15px; margin-left: 5px;" alt="Time" src="img/signup_form/info_simple.png"></a></h3>
