I'm trying to use a PHP script to include in all my pages via:

[php]<script src="../scripts/rollover.php?sub=1" type="text/javascript" language="Javascript"></SCRIPT>[/php]

The reason I'm doing this is so I can use one global rollover script that can be included with simple adjustment to the X in the "sub=X" field.

Now, I'm having problems getting the script to work. It works fine when a file is sitting in the root of my server (sub=0) but when I try to reference from any folders below the site (sub=1, etc.) the script doesn't seem to work.

Here is the code:
[php]
<?
for ($i=1; $i<=${"sub"}; $i=$i+1)
{

$Location=$Location+"../";

}

?>

<!--
var roll = 0;
if (navigator.appName == "Netscape" && parseFloat(navigator.appVersion) >= 3.05){roll=1;}
else if (navigator.appName == "Microsoft Internet Explorer" && parseFloat(navigator.appVersion) >= 3.02){roll=1;}

if ((document.images) && (roll == 1)) {

//preload main nav out images
whoOut = new Image();
whoOut.src = "<? echo $Location; ?>images/nav/main_who.gif";
whatOut = new Image();
whatOut.src = "<? echo $Location; ?>images/nav/main_what.gif";
newsOut = new Image();
newsOut.src = "<? echo $Location; ?>images/nav/main_about.gif";
contactOut = new Image();
contactOut.src = "<? echo $Location; ?>images/nav/main_contact.gif";
workOut = new Image();
workOut.src = "<? echo $Location; ?>images/nav/main_working.gif";
homeOut = new Image();
homeOut.src = "<? echo $Location; ?>images/nav/main_home.gif";
arrowOut = new Image();
arrowOut.src = "<? echo $Location; ?>images/nav/arrow.gif";


//preload main nav over images
whoOver = new Image();
whoOver.src = "<? echo $Location; ?>images/nav/main_who_o.gif";
whatOver = new Image();
whatOver.src = "<? echo $Location; ?>images/nav/main_what_o.gif";
newsOver = new Image();
newsOver.src = "<? echo $Location; ?>images/nav/main_about_o.gif";
contactOver = new Image();
contactOver.src = "<? echo $Location; ?>images/nav/main_contact_o.gif";
workOver = new Image();
workOver.src = "<? echo $Location; ?>images/nav/main_working_o.gif";
homeOver = new Image();
homeOver.src = "<? echo $Location; ?>images/nav/main_home_o.gif";
arrowOver = new Image();
arrowOver.src = "<? echo $Location; ?>images/nav/arrow_o.gif";

}



//Begin Function for Rollover On State
function imgOn(imgName) {
if ((document.images) && (roll==1)) {
document[imgName].src = eval(imgName + "Over.src");
}
}
//End Function for Rollover On State

//Begin Function for Rollover Off State
function imgOff(imgName) {
if ((document.images) && (roll==1)) {
document[imgName].src = eval(imgName + "Out.src");
}
}
//End Function for Rollover Off State

//Begin Function for Rollover On State
function terOn(imgName) {
if ((document.images) && (roll==1)) {
document[imgName].src = arrowOver.src;
}
}
//End Function for Rollover On State

//Begin Function for Rollover Off State
function terOff(imgName) {
if ((document.images) && (roll==1)) {
document[imgName].src = arrowOut.src;
}
}
//End Function for Rollover Off State

// End Function for Opening New Window with Event-Specified Parameters

[/php]

If anybody could help or could suggest a different forum where I could find help I'd appreciate it, I think at this point I've been staring at it for too long to pick up the problem.

Sorry I had to use the "php" vBcode b/c the "code" tag didn't seem to work

Try:

$Location .= "../"

I don't think an addition symbol works the same in PHP as it does in Javascript for string concatenation.

...it doesn't. it's also good programming practice to initialize $Location to the null string prior to doing a .= though php does that for you automatically

Heh, that was it. I figured it was something simple that I was just missing after staring at the code.

Thanks for the help .

also, if your image folder is located at the root of your site, you could bypass the whole script thing by using your image refs like "/images/myImage.jpg" instead of "images/myImage.jpg"...

less overhead.
