Answer 1

So yes you have to add the balise form at this end. Then I advice you to add a hidden value with your id.
<input type="hidden" name"id" value="<?php echo $param['id'] ; ?>">
After ad in your page submit.php,
<?php
include 'connection.php';
if (isset($_POST["id"])){
$id=$_POST["id"];#so you can recover your id
$myquery="UPDATE ... " ;
mysql_query($myquery) or die (mysql_error());
echo "update success";# you can add whatever you want here
}?>

You have to wrap all your form elements into the <form> tag. So place your closing tag (</form>) at the end of your form.
<form name="" id="form1" method="GET" action="submit.php">
<input name="..." />
<select>
<option value="...">...</option>
...
</select>
<button>...</button>
</form>
By the way: PHP's mysql-functions are deprecated. Use mysqli instead!
