[PHP] Countdown Timer

[vitinho444]

Hey guys, sorry for the oldtimes engine spam questions, i really want to make this one of the best engines for indie developers!

This time i come here saying that the building system is 100% done and fully operational, added some functions and stuff. Now i need to know, how can i make a easy to add countdown timer so it refreshes every second and when its done it does a refresh on the page.

I searched on google and found out this method:

http://stackoverflow.com/questions/1191 ... down-timer

But i cant seem to find a way to implement with the code.

The code im using is the time() function, and check if the time() >= $building_time //building time is the time when the build is finished.

So i want a function (the timer) to be able to get the difference between those two values and display a timer and countdown till 0, then i just need a refresh and the building system will do the rest.

Thanks for the help.

Whoever helps the dev of this engine gets a special spot in the credits, indie-resource.com is granted, but you can add your name to it.

I got this code originally I think from Alexander on these forums (runs the Nryis pbbg, I think?). I refined it slightly:
I use it with an include statement, setting its values just prior: $countdown for the time in seconds, $newpage for the page to go to. The other values you can set are $endcountermessage and $fontsize are optional.

Code: Select all

<?php
// uses $newpage for the page to go to after the count completes, if any
if (!isset($newpage)) $newpage="null"; // for when there is no page jump
if (!isset($endcountmessage)) $endcountmessage="---";
if (!isset($fontsize)) $fontsize=26;
if($countdown > 0)
{
// closing of PHP here so as to do the javascript
?>
            <span id='time'  style='text-align:left;font-size:<?php echo $fontsize; ?>px; color:#300; font-weight:bold'></span>
                        <script type='text/javascript'>
                        v=new Date();
                        var time=document.getElementById('time');
                        function date(){
                            n=new Date();
                            //here we insert the time
                            seconds=<?php echo $countdown; ?>-Math.round((n.getTime()-v.getTime())/1000.);
                            minutes=0;
                            hours=0;
                            if(seconds<0)
                            {
                                time.innerHTML='<?php echo $endcountmessage; ?>'; //'---';
                                // uncomment the line below to enable redirect at the end of the countdown
                                <?php if ($newpage<>"null") echo "document.location='".$newpage."';" ?>
                                //document.location='wurld.php';
                                }
                                else
                                {
                                    if(seconds>59)
                                    {
                                        minutes=Math.floor(seconds/60);
                                        seconds=seconds-minutes*60
                                    }
                                    if(minutes>59)
                                    {
                                            hours=Math.floor(minutes/60);
                                            minutes=minutes-hours*60
                                    }
                                    if(seconds<10)
                                    {
                                                seconds='0'+seconds
                                    }
                                    if(minutes<10)
                                    {
                                                    minutes='0'+minutes
                                    }
                                                time.innerHTML=' '+hours+':'+minutes+':'+seconds+'';
                                                document.title=hours+':'+minutes+':'+seconds;
                                                window.setTimeout('date();',999);
                                }
                                }
                                                date();
                        </script>
<?php
} // end of if $countdown>0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
?>

You said you use it with an include statement.. so i works like a function and i can just include it in the page i need the countdown.

But first i need to declare $countdown and $newpage etc right?

Also in the code i need to add for the $newpage to work a else on if($countdown > 0) so it goes to the $newpage. Right?
