PHP mail form : the mail is blank - php

Question

I'm a beginner, and I would like to make a PHP mail form like that :
But it doesn't work, I receive the mail but there is anything in it, and I don't understand why :/
Here is the HTML code for my form :
<form method=POST action=formmail.php >
<input type=hidden name=subject value=formmail>
<p>Pseudo* :<br>
<span class="padding1"><input type="text" name="your-name" value="" size="40" aria-required="true" aria-invalid="false"></span> </p>
<p>Email* :<br>
<span class="your-email padding1"><input type="email" name="your-email" value="" size="40" aria-required="true" aria-invalid="false"></span> </p>
<p>Link of the GIF* :<br>
<span class="link-url padding1"><input type="url" name="link-url" value="" aria-invalid="false"></span> </p>
<p><input type="submit" value="Send"><img class="ajax-loader" src="http://s584101063.onlinehome.fr/wp-content/plugins/contact-form-7/images/ajax-loader.gif" alt="Envoi en cours ..." style="visibility: hidden;"></p>
</div>
</form>
And here is my PHP code :
<?php
$TO = "saintscorporation#gmail.com";
$h = "From: " . $TO;
$message = "";
while (list($key, $val) = each($HTTP_POST_VARS)) {
$message .= "$key : $val\n";
}
mail($TO, $subject, $message, $h);
Header("Location: http://gifmyday.com/index.html");
?>

Answer 1

Adding the headers I put in the following code should help.
<?php
$TO = "saintscorporation#gmail.com";
// The headers have been changed a bit
$h = "From: " . $TO . "\r\n";
$h .= "MIME-Version: 1.0 \r\n" .
"Content-type: text/html charset=iso-8859-1 \r\n";
$message = "";
while (list($key, $val) = each($HTTP_POST_VARS)) {
$message .= "$key : $val\n";
}
mail($TO, $subject, $message, $h);
Header("Location: http://gifmyday.com/index.html");
?>
