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'>> 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'>> 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'>> 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'>> 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.
