PHP - Countdown Timer Help

Hey guys and gals!   I am currently working on implementing the following functionality in one of my pages:     Whenever a person with a specific IP address visits the page, an internal countdown timer of 2 hours should be started. Until that timer is active, the only response from the page ANYONE can get would be a predefined echo value. Once the timer has run out, the normal script execution of the rest of the page should be restored.   Any pointers and tips on how to approach that would be greatly appreciated.

Hi again people!

I found this code that codes for a countdown timer.
My problem is, how do I implement it?
I've found similar codes that leave me dazzled as I try to get them to work.

The URL from which I found this is:
http://scripts.franciscocharrua.com/server-side-countdown-clock.php

The code is:

Code: [Select]
function countdown_clock(year, month, day, hour, minute, format)
         {
         //I chose a div as the container for the timer, but
         //it can be an input tag inside a form, or anything
         //who's displayed content can be changed through
         //client-side scripting.
         html_code = '<div id="countdown"></div>';

         document.write(html_code);

         Today = new Date();
         Todays_Year = Today.getFullYear() - 2000;
         Todays_Month = Today.getMonth();

         <?
         $date = getDate();

         $second = $date["seconds"];
         $minute = $date["minutes"];
         $hour = $date["hours"];
         $day = $date["mday"];
         $month = $date["mon"];
         $month_name = $date["month"];
         $year = $date["year"];
         ?>

         //Computes the time difference between the client computer and the server.
         Server_Date = (new Date(<?= $year - 2000 ?>, <?= $month ?>, <?= $day ?>,
                                 <?= $hour ?>, <?= $minute ?>, <?= $second ?>)).getTime();
         Todays_Date = (new Date(Todays_Year, Todays_Month, Today.getDate(),
                                 Today.getHours(), Today.getMinutes(), Today.getSeconds())).getTime();

         countdown(year, month, day, hour, minute, (Todays_Date - Server_Date), format);
         }

function countdown(year, month, day, hour, minute, time_difference, format)
         {
         Today = new Date();
         Todays_Year = Today.getFullYear() - 2000;
         Todays_Month = Today.getMonth();

         //Convert today's date and the target date into miliseconds.

         Todays_Date = (new Date(Todays_Year, Todays_Month, Today.getDate(),
                                 Today.getHours(), Today.getMinutes(), Today.getSeconds())).getTime();
         Target_Date = (new Date(year, month, day, hour, minute, 00)).getTime();

         //Find their difference, and convert that into seconds.
         //Taking into account the time differential between the client computer and the server.
         Time_Left = Math.round((Target_Date - Todays_Date + time_difference) / 1000);

         if(Time_Left < 0)
            Time_Left = 0;

         switch(format)
               {
               case 0:
                    //The simplest way to display the time left.
                    document.all.countdown.innerHTML = Time_Left + ' seconds';
                    break;
               case 1:
                    //More datailed.
                    days = Math.floor(Time_Left / (60 * 60 * 24));
                    Time_Left %= (60 * 60 * 24);
                    hours = Math.floor(Time_Left / (60 * 60));
                    Time_Left %= (60 * 60);
                    minutes = Math.floor(Time_Left / 60);
                    Time_Left %= 60;
                    seconds = Time_Left;

                    dps = 's'; hps = 's'; mps = 's'; sps = 's';
                    //ps is short for plural suffix.
                    if(days == 1) dps ='';
                    if(hours == 1) hps ='';
                    if(minutes == 1) mps ='';
                    if(seconds == 1) sps ='';

                    document.all.countdown.innerHTML = days + ' day' + dps + ' ';
                    document.all.countdown.innerHTML += hours + ' hour' + hps + ' ';
                    document.all.countdown.innerHTML += minutes + ' minute' + mps + ' and ';
                    document.all.countdown.innerHTML += seconds + ' second' + sps;
                    break;
               default:
                    document.all.countdown.innerHTML = Time_Left + ' seconds';
               }

         //Recursive call, keeps the clock ticking.
         setTimeout('countdown(' + year + ',' + month + ',' + day + ',' + hour + ',' + minute + ',' +
                     time_difference + ', ' + format + ');', 1000);
         }
I've tried saving the file as a php file and html file, but to no avail...

So I have a count down timer on my site.   http://fpsboost.net

And I am clueless as to how I would set a final date with this. Cant find where it's grabbing the info for "finaldate" or anything like that. Want to set the final date to feb 1st 2015

Javascript newb here. Anyone willing to help would be greatly appreciated.

Thanks in advance!   Btw, I'm using a generic js countdown timer from: http://hilios.github...uery.countdown/ called "The Final Countdown for jQuery v2.0.4" It was preloaded in a template that I downloaded for my site.

Hi,

This is my first post so dont kill me if i did somthing wrong.

Im trying to make a simple php/javascript page that will display the time remaining in each period every day (we have 4 periods per day). I found a nice javascript library from www.hashemian.com and am using the example that he linked to to do multiple countdown timers on one page.

The problem i am having is that the only way i can think of to make it so that it counts down to a dynamic date is to specify that date as a variable and then combine it with the string that specifys the rest of the date/time combo for the target date/time.

The current live version is at smd75jr.com/test/index2.php

The first timer is just a test that im using to make sure i havent completely broken it.
THe second timer is the one im trying to troubleshoot, it is currently set for 11:59 PM EST "today". (see code below)


Any help would be greatly appreciated!!



This is my code:

Code: [Select]
<html>
<head>
<title>Multiple Countdown Clocks</title>
</head>
<body>
<div id="clock1">[clock1]</div>
<div id="clock2">[clock2]</div>
</body>
<script language="JavaScript">


StartCountDown("clock1","06/27/2012 9:33 PM -0400")
StartCountDown("clock2","periodTest")
TodaysDate()



//var today = new Date()
//var todayMonth = today.getMonth() + 1
//var todayDay = today.getDate()
//var todayYear = today.getFullYear()
//var todayDate = (todayMonth + "/" + todayDay + "/" + todayYear)

var periodTest = (todayDate + " 11:59 PM -0400")


var periodA1 = (todayDate + " 8:53 AM -0400")
var periodA2 = (todayDate + " 10:26 AM -0400")
var periodA31 = (todayDate + " 12:32 PM -0400")
var periodLunch1 = (todayDate + " 11:00 AM -0400")
var periodLunch2 = (todayDate + " 12:32 PM -0400")
var periodA32 = (todayDate + " 11:59 AM -0400")
var periodA4 = (todayDate + " 2:05 PM -0400")



//function Periods(todayDate, periodA1, periodA2, periodA31, periodA32, periodA4, periodB1, periodB2, periodB31, periodB32, periodB4, periodLunch1, periodLunch2, periodSchoolStart, periodSchoolEnd)
// {
// var today = new Date()
// var todayMonth = today.getMonth() + 1
// var todayDay = today.getDate()
// var todayYear = today.getFullYear()
// var todayDate = (todayMonth + "/" + todayDay + "/" + todayYear)
//
// var periodA1 = (todayDate + " 21:25 PM -0400")
// }




function TodaysDate(todayDate)
{
var today = new Date()
var todayMonth = today.getMonth() + 1
var todayDay = today.getDate()
var todayYear = today.getFullYear()
var todayDate = (todayMonth + "/" + todayDay + "/" + todayYear)
}

Hey all!
In the code in question I echo out individual records of data from MySQL successfully. For each record there is a number which is used as a var in the javascript that does the count-down-timer part.
However when I view the resulting page the timer works dynamically only with the first record. With the rest, the timer is static.

Code: [Select]
<?
$result0 = mysql_query("SELECT * FROM table WHERE field='$value'");
while ($riw0 = mysql_fetch_assoc($result0)) {
$seconds1 = $riw0['seconds'] ;
//// echo out data and set variable for the number of seconds to count down
?>

<script language="JavaScript">
var countDownInterval=<?=$seconds1?>;
var c_reloadwidth=200
</script>
<ilayer id="c_reload" width=&{c_reloadwidth}; ><layer id="c_reload2" width=&{c_reloadwidth}; left=0 top=0></layer></ilayer>
<script>
var countDownTime=countDownInterval+1;
function countDown(){
countDownTime--;
if (countDownTime <=0){
countDownTime=countDownInterval;
clearTimeout(counter)
window.location.href="military3.php" //Redirection URL
return
}
var mins = Math.floor(countDownTime/60)
var secs = countDownTime-(mins*60)
if (document.all) //if IE 4+
document.all.countDownText.innerText = mins+" minutes "+secs+ " ";
else if (document.getElementById) //else if NS6+
document.getElementById("countDownText").innerHTML=mins+" minutes "+secs+ " "
else if (document.layers){
document.c_reload.document.c_reload2.document.write('Soldiers will be ready in... <span id="countDownText">'+countDownTime+' </span> seconds')
document.c_reload.document.c_reload2.document.close()
}
counter=setTimeout("countDown()", 1000);
}

function startit(){
if (document.all||document.getElementById)
document.write('Soldiers will be ready in <span id="countDownText">'+countDownTime+' </span> seconds')
countDown()
}

if (document.all||document.getElementById)
startit()
else
window.onload=startit
</script>
<? } ?>

I tried replacing the javascript vars with PHP echoes for unique variables, but then no timer shows up, even static.
So could anyone advice me on how I could use this code to apply for all MySQL records?

Thanks in advance,
Thauwa

P.S. If I am unclear with my quandary, do let me know. Thank you.

<?php
for($test=100; $test!=0; $test--){
echo $test."\n";
sleep(1);}
?>

Instead of counting down like

100
99
98
etc

how can I make it replace the previous number? So it would just be like

100 then 100 would go away and 99 would replace it and so on

Any help is appreciated

Hey Guy's   I need a quick fix to solve an urgent problem..   I used to do some coding years ago but the old grey matter is not so responsive these days and I have been up all night trying to resolve a problem.   I have built a website for my daughters and created a simple web form but I have come unstuck. All those skills I once took for granted are gone.   So here's where I am at. I've created an input form_mail.html, a contact.php and a reply.html page uploaded them to the Server and hit an error when I tried to send a message. The problem it seems is with the PHP.ini File.   In short I don't have one Duh! Yes I know I should go back and study and that much I intend to do I am currently installing xxampp, MySQL and php on my new laptop.   But in the meantime I need your help urgently..   What code do I need in the php.ini file to make the Form Mail work?   Is there somewhere on the web where I can see a simple code, I am just too tired to wade through heavy docs right now.   Your help would be much appreciated at this time.   Sincerely   Tam        

Hello.
Well i'm trying to make a timer to execute some code.
Basically I want 3 minutes, every 3 minutes a piece of code is activated, then another 3 minutes later it does so again.
But I have tried different ways of doing this, I tried with cookies and found out the person with the cookie is the only one that can refresh the page to activate the code.
Same with sessions.
And all the others are usually interrupted and start the timer again when the page reset.

So yeah, I don't want it to be interrupted by refreshing.
So any help please?
I also tried with timestamps, this has proven to be the best way but I can never get it working 100%

How am i able to setup a countdown timer?
I use the time(); function and want to compare that time with another time that is 8 hours ahead to form a countdown timer, how am i able to do this using php?

Can someone show me the way? I am creating a online examination with time pressured. For example Part I of examination is only good for 20 mins. now if 20 mins is over it will be lock or good as submit. How will I do that?

tnx everyone.

Well I usually run my scripts in CLI.. I have it do something then sleep for x amounr of settings, is there anyway to make it show me the seconds counting down instead of just a blinkin cursor?

I would like to have this done in php but am about to lose my mind. Just need a script to countdown to midnight, server time. Doesn't have to be live, just something to see when the page is reloaded. Any help would be much aprreciated

Im looking for some example code for countdowns.

I need to be able to count down to the same time each day for example 9PM each day.

and be displayed as 5hr 8m 15s.

When the timer runs out, then run some code then start again for the next day.

what would be the best route to take for this?

Thanks in advance
