Got this page, a player clicks the "accept challenge" button, then it is recorded in the database that the challenge as been started and once the form has been self submitted, the button is disabled. It does what I expect, but I have to refresh the page again for the button to be displayed as disabled. How can I do it so the page is changed once the form has been submitted? 

<?php
session_start();what  but after clicking a button I have to refresh the page again, before the button is displayed as disabled
include('functions.php');
connect();
?>

In the safe.php file 

<?php
$statsGet = mysql_query("
SELECT * FROM stats WHERE userid='".$_SESSION['userid']."'
") or die ("Could not get statistics from database");
$stats = mysql_fetch_assoc($statsGet);

$chal1Get = mysql_query("
SELECT * FROM chal1 WHERE userid='".$_SESSION['userid']."'
") or die ("Could not find data on challenge 1 from database");
$chal1 = mysql_fetch_assoc($chal1Get);

$task1 = $chal1['task1'];
$task2 = $chal1['task2'];
$task3 = $chal1['task3'];
$task4 = $chal1['task4'];
$start1 = $chal1['start1'];
$start2 = $chal1['start2'];
$start3 = $chal1['start3'];
$start4 = $chal1['start4'];


$curInt = $stats['int'];
$curStr = $stats['str'];
$curXp = $stats['xp'];
$curLevel = $stats['level'];
$curGold = $stats['gold'];

if ($curXp>=0&&$curXp<=74) {
$curLevel = 1;
mysql_query("UPDATE stats SET level='$curLevel' WHERE userid='".$_SESSION['userid']."'")
or die ("Could not update current level 1");
} elseif ($curXp>=75&&$curXp<=157) {
$curLevel = 2;
mysql_query("UPDATE stats SET level='$curLevel' WHERE userid='".$_SESSION['userid']."'")
or die ("Could not update current level 2");
} elseif ($curXp>=158&&$curXp<=323) {
$curLevel = 3;
mysql_query("UPDATE stats SET level='$curLevel' WHERE userid='".$_SESSION['userid']."'")
or die ("Could not update current level 3");
} elseif ($curXp>=324&&$curXp<=655) {
$curLevel = 4;
mysql_query("UPDATE stats SET level='$curLevel' WHERE userid='".$_SESSION['userid']."'")
or die ("Could not update current level 4");
} elseif ($curXp>=656&&$curXp<=1319) {

So, $start1, $start2, $start3 has nothing to do with posting the form, it is only database call?  Yet, you are using that to determine the state of the button?  So, you should either.

 

1. Check the form submission to set the button.

OR,

2. Move the include for safe.php BELOW your updates, so that you pull the info AFTER you update it. (currently you update the info after you pull it).

jcbones,

The variables $start1, $start2 and $start3 contain a value of 1 or 0. 1 meaning the challenge has already been accepted. The values are checked first in safe.php and then the page buttons are displayed - a value of 0 displays a normal button, a value of 1 displays a disabled button. If a button is clicked the database is updated. I'll try what you said and add my safe.php file at the bottom and see if it fixes things.
