Umm you can't run javascript variables in PHP

this is javascript

var timerID = null;
var timerRunning = false;
function stopclock (){
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
}
function showtime () {
var now = new Date();
var hours = now.getHours();
var minutes = now.getMinutes();
var seconds = now.getSeconds()
var timeValue = "" + ((hours >12) ? hours -12 :hours)
if (timeValue == "0") timeValue = 12;
timeValue += ((minutes < 10) ? ":0" : ":") + minutes
timeValue += ((seconds < 10) ? ":0" : ":") + seconds
timeValue += (hours >= 12) ? " P.M." : " A.M."
document.clock.face.value = timeValue;
timerID = setTimeout("showtime()",1000);
timerRunning = true;
}
function startclock() {
stopclock();
showtime();
}

this is PHP

<?
//how to make if hour=5 it show "haha"??
if(hours==5)
{ echo "haha";}
?>

But with a very big problems. Variablies in PHP are indicated by a "$" so "hour" should be "$hours" which leads to the fact that "$hours" is undefined in PHP. And To get the value of "hours" to PHP you will have to send it via GET or POST.

The other option is to run all the code in javascript.

hi thanks. i want text on my page.
Actually i want post to database, is that a way use javascript to update database when hour=5?
Or use javascript to call a function that update the database?
btw, how to use GET or POST between javascript and php?
Thanks again

Krik

So when the hour reaches 5 you want to update your database.

You could use the PHP [man]date[/man] function

if(date('h') == 5) {
// update database
}

If you need the javascript to send some data to the PHP when it reaches 5 you can create a hidden form and form field and have the javascript submit it to the PHP. This would be the POST method.

<script>
if(hours == 5) {
document.myform.submit();
}
</script>
<html>
<form name="myform" id="myform" method="post" action="submitdata.php"> 
<input type="hidden" name="mydata" id="mydata" value=""> <!-- add your data here -->
</form>
</html>

<?php
if(issest($_POST['mydata'])) {
$mydata = $_POST['mydata'];
// update database
}
?>

It should be fine. I only offered that as an option in case you needed to send some data to the PHP script.

As to why it wasn't submiting data to your data base I would have to see your PHP and SQL.

if(hours==3){
document.write("haha")
}

That will not work because the "hours" variable is a local scope. It was set in the "showtime" function so in the above segment "hours" is undefined. To set "hours" in a global scope set "var hours;" outside of the functions.

var hours;
var timerID = null;
var timerRunning = false;
function stopclock (){
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
}
function showtime () {
var now = new Date();
hours = now.getHours(); // note the change here as well
var minutes = now.getMinutes();
var seconds = now.getSeconds()
var timeValue = "" + ((hours >12) ? hours -12 :hours)
if (timeValue == "0") timeValue = 12;
timeValue += ((minutes < 10) ? ":0" : ":") + minutes
timeValue += ((seconds < 10) ? ":0" : ":") + seconds
timeValue += (hours >= 12) ? " P.M." : " A.M."
document.clock.face.value = timeValue;
timerID = setTimeout("showtime()",1000);
timerRunning = true;
}
function startclock() {
stopclock();
showtime();
}

if(hours==3){
document.write("haha")
}

Also the "document.write" will just write to first character space on the screen which may be under something. Use "alert()" as it will make sure it doesn't get hidden

if(hours==3){
alert("haha")
}

As well as what Krik says, the showtime() function doesn't run until startclok() is run. And that doesn't run until the page has loaded. Which doesn't happen until a long time after that "if(hours==3){...}" bit has been executed. In fact, where it is now, the <body> element doesn't even exist yet when it executes.

How to make it call the function reload() to refresh or redirect if time =12.00 a.m ?

Krik

Was thinking that I made a small error in what I last posted and I think it is related to your last question.

Place the

if(hours==3){
alert("haha")
}

in the "showtime" function.

This will make it so that when the timer hits the correct time that "if" will be triggered.

I followed ur instruction put inside showtime() function, but nothing happen when comes to 3 AM or 3 PM. Helps~~ Thanks again.:eek:

Krik

Did you place it after the "hours" variable was defined?

hackerzz

of course, u can try copy paste the code.. if statement not triggered
