PHP: Interactive Contact form not working - php

Question

Why is this form not working?
I'm creating a form that sends messages to users.
The user email comes from the database.
The query that searches the database is influenced by some data sent previously to the browser.
The problem at the moment is:
When one clicks to submit, nothing really happens.
Got a file called mini-contact.php with the following:
Script to proccess the form:
<?php
var_dump($_POST);
error_reporting(E_ALL);
$company=$_GET['company'];
$sql = "SELECT * FROM companies WHERE companies.companyID= '$company'";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
$row = mysqli_fetch_assoc($result);
$companyemail = $row['Email_Address'];
if(isset($_POST['submit'])){
$to = "tiagomartinsperes#gmail.com"; // this is your Email address
$from = $_POST['email']; // this is the sender's Email address
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$subject = $_POST['subject'];
$subject2 = "Copy of your form submission";
$message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
$message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];
$header = "From:" . $from;
$header.= "MIME-Version: 1.0\r\n";
$header.= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$header.= "X-Priority: 1\r\n";
$header2 = "From:" . $to;
$header2.= "MIME-Version: 1.0\r\n";
$header2.= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$header2.= "X-Priority: 1\r\n";
$status1 = mail($to,$subject,$message,$header);
$status2 = mail($from,$subject2,$message2,$header2); // sends a copy of the message to the sender
if($status1 and $status2){
$first_name = $_POST['first_name'];
echo 'Mail Sent. Thank you' . $first_name . ', we will contact you shortly.';
} else {
echo '<p>Something went wrong, Please try again!</p>';
}
// You can also use header('Location: thank_you.php'); to redirect to another page.
}
}
?>
The actual form:
<form id="contact-form" method="post" action="">
<div class="messages"></div>
<div class="controls">
<div class="row">
<div class="col-md-6 col-sm-6 no-left-pad">

</div>
</div>
<div class="row">

<div class="form-group">

<textarea name="message" class="form-control" placeholder="Please enter your message" rows="4" required="required" data-error=" Please enter your message."></textarea>
<div class="help-block with-errors"></div>
</div>
</div>
<div class="col-md-12 no-left-pad">
<p class="text-muted"><strong>*</strong> These fields are required.</p>
</div>
<div class="col-md-12 no-left-pad">
<input type="submit" class="btn btn-default caps" name="submit" value="Submit">
</div>
</div>
</div>
</form>
What am I doing wrong?
Thank you for your time

One needs to have SMPT properly configure so that it works.
