editing a record in a database with a form
first of all i would like to appolagise on the amount of code i am about
to paste, i didn't want to snippet any more incase its a bit that's giving
me the errors
i have a table named contacts and want to update the table by a form.
i am not sure if its the form or if its the code as the delete user isn't
working
i have just started to learn this (a few days ago)so the code might be
messy or not 100% secure as it should this is for a offline database so i
would improve it as i learn.
<?php include("header.php");
//include database connection
include 'db_connect.php';
$action = isset( $_POST['action'] ) ? $_POST['action'] : "";
if($action == "update"){
//write query
$query = "update contacts
set

$query = "DELETE FROM users WHERE id =
