I have a PHP-script that adds time into a SQL-DB like this:
$howlong = 75; // Amount of seconds
$timetowait=time()+ $howlong; // This inserts into "timetowait" in SQL DB
Then to show my users how long they have to wait, I have this:
$timeleft= $rows['timetowait']; // This is the field in DB from above^
func_time($timeleft); // Function below, which shows the time left
The function above is:
function func_time($until){
$now = time();
$difference = $until - $now;
$seconds = $difference;
$output = "$seconds seconds";
return $output;
}
It works fine, but I want it to be a dynamic countdown. (Automaticly counting down, without refreshing the site) My problem here, is that I am using the "time()", and not pure text (f.ex 21/11/2013 20:00)
Usually this type of "countdown" like thing is handled by Javascript:
On the client side you could do something like this:
function countdown(seconds) {
if(seconds > 0) {
alert(seconds + ' Seconds Left');
setTimeout(function(){
countdown(--seconds);
}, 1000);
}
else {
alert('Time out!');
}
}
