Right, you could place my code in the header file as well. I must've missed that you had a header file.

Nice Renegade, that works perfectly.

What about something like this?

<?php
// if string length is zero, or does not exist
if(strlen($bg) == \"0\") {
  $bg = \"images/default.gif\";
}
?>

This is more or less what mscreashuns has posted. And you might want to get a bit more complicated and check if the image your changing exists. If it doesn't, then go to default.

<?php
// if string length is zero, does not exist, or file doesn't exist
if(!file_exists($bg) || strlen($bg) == \"0\") {
  $bg = \"images/default.gif\";
}
?>

That if() statement will go just before the line:

<?php
<img src=\" echo $bg \">
?>

Which is in your header file right? So, there's no need to edit all 400+ pages. If $bg is already set, then, it won't go to default.

Thanks mscreashuns, but I don't think that is what I am going for.

Let me rephrase...

If I define $bg on the staff.php, the background (bg) image will be displayed on staff.php by the header file where the bg tag is. Now, if I do not define $bg I want it to default to localhost/images/bg.gif. I want that code in the header. The site I am working on has 400+ pages and I can't go into everyone and place a code there.

Does that make sense?

This is how it would look in my own language.

if {bg = "anything"
then {make it the background image}

else {make the background = localhost/images/defaultbg.gif}

Okay, what you can do is add the code I gave you to each page, and on the pages where $bg should be defined, add this line before the code above:

<?php
$bg = "whatever";
?>

This way it will use whatever that line says, since $bg is not empty.

teammatt3 — Sat, 12 Nov 2005 01:10:07 +0000

Can you explain that a little? Where would the default url bg go (http://localhost/images/default.gif) and the variable inside staff.php?

I am new to PHP, I just used includes before.

mscreashuns — Sat, 12 Nov 2005 00:59:17 +0000

Yep, do something like this:

<?php
if ($bg == "") {
$bg = "whatever";
}
?>

'
There are other ways to determine if a variable is empty, but that's what I always do.
