Hello everyone, just wanna to revive this forum. This is simple and secured(probably) php website code by me.
Additionally I wanna to ask for some suggestions about this, what i can improve or enhance.
ps. idk if all is correct here cuz I change this from my admin panel on quickly (ex. k_users -> bg_users)
index.php
<?php
session_start(); // Code created by Karmel, Copyright 2015 Karmel Inc.
include_once "include/config.php"; // ------- Not for commercial use
try{$db = new PDO("mysql:host=".$server_ip, $user, $password);}
catch(PDOException $e){die('Error connecting to the database');}
function login_check($db, $db0){ // Code sourced for admin panel
if(isset($_SESSION['user_code'], $_SESSION['user_id'], $_SESSION['user_salt'])){
$dbh = $db->prepare("SELECT user_code, a_salt FROM $db0.bg_users WHERE user_id = :user_id");
$dbh->bindParam(':user_id', $_SESSION['user_id'], PDO: ARAM_STR, 20);
$dbh->execute();$dbh = $dbh->fetch();
if($_SESSION['user_salt'] == $dbh['a_salt']){ //&& $_SESSION['user_time'] > date("Y-m-d H:i ",time()-1200)){ // 20min session
$dbh = $db->prepare("UPDATE $db0.bg_users SET a_activetime = '".date("Y-m-d H:i")."' WHERE a_index = '".$dbh['a_index']."'");
$dbh->execute();return true;
}else{return false;}
// for admin panel you should use there ip compare, $_SERVER['REMOTE_ADDR'] & bg_users latest a_activetime
}
}
?>
