Simple problem about variables

Anon

Right I'm making a wecam portal, and when you click the cams they appear in a popup window which refreshes, anyway I'm using a single file and php to decide which image it displays, anyway here is my code the variable i used was "$cam"

<head>
<STYLE TYPE="text/css">
<!--

body { scrollbar-face-color:#ffffff;
scrollbar-track-color:#ffffff;
scrollbar-arrow-color:#fe00d2;
scrollbar-3dLight-Color:#ffffff;
scrollbar-Base-Color:#ffffff;
scrollbar-DarkShadow-Color:#fe00d2;
scrollbar-Highlight-Color:#fe00d2;
}
{ margin-top: 10 }
.cambox { border: #FF00CC; border-style: dashed; border-top-width: 1px; border-right-width: 1px; border-bottom-width: 1px; border-left-width: 1px}

-->

</STYLE>

	if (document.images) {
		document.refrimage.src = "$cam" + "?" + dummystr
	} else {
		window.location.reload()
	}
	Interv = 30
}
document.clock.time.value = Interv
timrID = setTimeout("startClock2()", 1000)

}

James,
what is the question ?
and where is the php code ?

Anon

well the question is how do I get it to replace $cam with a url and the code is

<!--

var Interv = 2

function startClock2() {
Interv = Interv - 1

var now = new Date()
var dummystr = parseInt(now.getTime() / 1000)
delete now

if (Interv < 0) {
	if (document.images) {
		document.refrimage.src = "$cam" + "?" + dummystr
	} else {
		window.location.reload()
	}
	Interv = 30
}
document.clock.time.value = Interv
timrID = setTimeout("startClock2()", 1000)

}

//-->

Which is java I know but I want to change $cam to a url

and this is the 2nd $cam part

I've used methods similar before but that was in a php include and I think thats why its not working. any ideas why?

nimbus

are you printing the whole stuff with a php echo? if not try changing the line so that php knows that you want it to something:

document.refrimage.src = "<?php echo $cam; ?>" + "?" + dummystr

btw, it's not java, it's javascript. and dreamweaver sucks. :-)

This is not JAVA, it's Javascript.

Second, if you want PHP print a URL for $cam, you'll have to change '$cam' into a PHP statement that prints the value of $cam, so it will be printed when PHP prints the javascript to the client.

yeah i know its javascript, but its quicker to type 4 letters than 10, and its todays modern quick fix world we need to save all the time we can to do more constructive things. anyway it works now so thanks hehe
