Please help me with proper guidance where am i stuck here or i am making mistake

Answer 1

as per your code you put one condition i.e.
if(isset($_GET['id']))
{
.....
}
but in html form you are not pass any id field add id field and try your condition will verify and update will work.
just add one field like below.. remaining is same.
<form action="UPDATE.php?id=<?php echo $id; ?>" method="post" name="insertform">
<input type="hidden" name="id" value="<?php echo $id; ?>" >
...............
.................
</form>
Note: In HTML page id of field should be unique.
