above URLs are also not working getting 404 error

I’ve added echo ”; print_r($_POST); echo ”; in front of all php code and this is the output:

Array
(
[id] => H27427
[type] => value
[name] => name
[number] => number

[update] => Update
)

Is it normal to have a value for update in the post array?

When I add this code
if($query->execute())
{
echo “Added!”; } else {echo “Error:”;
print_r($dbh->errorInfo());}

I get this message:

Array ( [0] => 00000 [1] => [2] =>
