Hi i would like to stop user refreshing on the same page... I have this game which when the user loses in an attack the user could keep on refreshing the page till the opponents hp is 0 and then he would win the fight. so what i want to do is when the user trys to refresh a message would say that he cannot refresh that page or something. below is the code of what i have so far... sorry its a bit mess and long.. [code]<?php session_start(); require "global_func.php"; if($_SESSION['loggedin']==0) { header("Location: login.php");exit; } $userid=$_SESSION['userid']; require "header.php"; $h = new headers; $h->startheaders(); include "mysql.php"; global $c; $is=mysql_query("SELECT u.*,us.* FROM users u LEFT JOIN userstats us ON u.userid=us.userid WHERE u.userid=$userid",$c) or die(mysql_error()); $ir=mysql_fetch_array($is); check_level(); $fm=money_formatter($ir['money']); $cm=money_formatter($ir['crystals'],''); $lv=date('F j, Y, g:i a',$ir['laston']); $h->userdata($ir,$lv,$fm,$cm,0); $_GET['ID'] == (int) $_GET['ID']; if(!$_GET['ID']) { print "WTF you doing, bro?"; $h->endpage(); exit; } else if($_GET['ID'] == $userid) { print "Only the crazy attack themselves"; $h->endpage(); exit; } //get player data $youdata=$ir; $q=mysql_query("SELECT u.*,us.* FROM users u LEFT JOIN userstats us ON u.userid=us.userid WHERE u.userid={$_GET['ID']}",$c); $odata=mysql_fetch_array($q); if($odata['hp'] == 1) { print "This player is unconscious.<br /> <a href='index.php'>&gt; Back</a>"; $h->endpage(); $_SESSION['attacking']=0; exit; } else if($odata['hospital'] and $ir['hospital']==0) { print "This player is in hospital.<br /> <a href='index.php'>&gt; Back</a>"; $h->endpage(); $_SESSION['attacking']=0; exit; } else if($odata['fedjail'] == 1) { print "The other person is in fed!<br /> <a href='index.php'>&gt; Back</a>"; $h->endpage(); $_SESSION['attacking']=0; exit; } else if($ir['hospital'] and !$odata['hospital']) { print "Stop trying to attack other people your in hospital.<br /> <a href='hospital.php'>&gt; Back</a>"; $h->endpage(); $_SESSION['attacking']=0; exit; } print "<table width=100%><tr><td colspan=2 align=center>"; if($_GET['wepid']) { if($_SESSION['attacking']==0) { if ($youdata['energy'] >= $youdata['maxenergy']/2) { $youdata['energy']-= $youdata['maxenergy']/2; $me=$youdata['maxenergy']/2; mysql_query("UPDATE users SET energy=energy- {$me} WHERE userid=$userid",$c); $_SESSION['attacklog']=""; } else { print "You can only attack someone when you have 50% energy"; $h->endpage(); exit; } } $_SESSION['attacking']=1; $_GET['wepid'] = (int) $_GET['wepid']; $_GET['nextstep'] = (int) $_GET['nextstep']; //damage $qr=mysql_query("SELECT * FROM inventory WHERE inv_itemid={$_GET['wepid']} and inv_userid=$userid",$c); if(mysql_num_rows($qr)==0) { print "Stop trying to abuse a game bug.

i've been looking for a script for email validation to check if the email is vaild also to send an email validation to validate that account. any help? also how would the account be activated via email?

hi what i want to do is when a user registers it checks the ip address to see if it is already in the database and if it is it would refuse the user..... the problem is if the user are on a LAN so he could register on one computer then move to the nxt and register again creating lots of users. so what i want to do is to stop users registering on a LAN only to restrict it to one user. so far this is what i have below $ip = ($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR']; $q=mysql_query("SELECT * FROM users WHERE lastip='$ip'",$c); if(mysql_num_rows($q)) { die("Only <B>ONE</B> user per IP"); }
