Javascript/PHP problem

[Thomisback]

Hi everyone,

 

I have made a game in which you can build buildings, you have to wait for the time to elapse before you can build a new one. Currently I am using a Javascript script but this can easily be bypassed by changing your computers time! Now I am trying to convert it into PHP to make it more secure but I have got no clue where to start.

 

My javascript code looks like this:

<script   type="text/javascript">

v=new Date();
var bxx=document.getElementById('bxx');
function t(){
n=new Date();
ss={time};
s=ss-Math.round((n.getTime()-v.getTime())/1000.);
m=0;h=0;
if(s<0){
	bxx.innerHTML='{ready}<br><a href=link>{continue}</a>';
}else{
	if(s>59){m=Math.floor(s/60);s=s-m*60;}
	if(m>59){h=Math.floor(m/60);m=m-h*60;}
	if(s<10){s="0"+s}
	if(m<10){m="0"+m}
	bxx.innerHTML=h+':'+m+':'+s+'<br><a href="link">{cancel}<br><br>{name}</a>';
}
window.setTimeout("t();",999);
}
window.onload=t;

</script>

 

I'm sorry if my question is not appropriate for this forum, but thanks!

I've got some other functions which need to be converted as well :/ this is one of them...

And what exactly do want us to do? Were not here to write code for you.

I'm just wondering if there is an easy way to do this in PHP or whether someone knows a workaround to execute javascript on the server-side.

What you could do is (when a user finishes creating a building) store the time the user finished in a database along with something that identifies the user. Then, if they try to create another building, check this database to see whether or not sufficient time has passed.

you could have php write out the current time according to the server and store it in a hidden [display: none;] and DISABLED <input> where the value of this input is the servers time.  From there have javascript pickup that value to do its "has enough time passed?" calculations.

 

<?php
  echo '<input style="display: none;" value="' . date("H:i:s") . '" DISABLED />';
?>

Thanks for your replies, i'm trying to figure it out
