variable array value passing from an include

miraclewhipkey

I have an include file that has an array of hex codes in it. It looks something like this:

<?
$color = ("000000","FFFFFF","CC0000");
?>

Thats abbreviated but you get the point. At the bottom of the same include file, I also have a CSS style tag that declares the color of links using the variable, like this:

A {
   color: #<? echo $color[2]; ?>;
}

That works fine. When I view the source of the file that uses this include, it shows the CSS style tag where it should be, and it prints the proper hex code in it place.

The problem I'm having is that if I try to use this variable in the main document that uses the include, it doesn't print anything. I would have code like this:

<body bgcolor="#<? echo $color[1]; ?>">

but it would come out like this when I view source:

<body bgcolor="#">

ANy ideas as to what I need to do to the variable in the include file to get it to pass the values from its array to the main files?

Have you placed the include code above your body tag ? .... sorry but this seems the most obvious.

Yes. I know it is reading the include file, because when I view source on the main file, I can see the CSS block with the hex code printed from the variable array. That CSS block is part of the include, not the main file. It "echoes" the value in the CSS block in the same include file, but it just won't send the value of the variable FROM the include TO the main file that is "including it.

Anyone else have this problem, or know how to fix that?

Do you have any instance where you do a comparison with $color? A common bug is to use one = when you mean ==

Example:

if($color[0]='') { #do something }

unfortunately $color[0] is now an empty string, even if it didn't start that way.

Should be (of course):

if($color[0]=='') {....}

where you are having trouble use this:

<?php

/// include your file

echo "<pre>";
echo gettype($color);
echo "<br>";
print_r($color);
echo "</pre>";

/// where you can't find $color

this will show you what exactly your program thinks $color is at that moment in time.
