Using Class to create color scheme

[seanmayhew]

I'm trying to create a site with two class files a Category Index file and an article page for each category. I'd like to to set the color scheme for each category based on an include file

function ArtScheme($SchemeSelected){ 
switch($SchemeSelected) 
{ 
case "home": 
include ('homescheme.php'); 
break; 
default: echo "Your Color Scheme does not work"; 
} 
} 
$SchemeNeeded = "home"; 
ArtScheme($SchemeNeeded); 

<table width="775" border="0" cellpadding="1" cellspacing="0" bgcolor="<?php $bordercolor?>">

Here is what my include file looks like

<?
$highlightcolor = "#EBD7AB";
$bordercolor = "#CC9933";
$stripecolor = "#FFFFCE";
?>

All this produces is a bunch of empty quotes bgcolor=""

Any help would be greatly appreciated

You are missing the = operand from the short tags. In other words, this:

bgcolor="<? $bordercolor ?>"

should read:

bgcolor="<?= $bordercolor ?>"

I think when you include the file inside of a function the stuff in the included file, including the variables are restricted to the scope of the function that they were included in.

Does that make sense? The variables are only accessible from within the ArtScheme function. You can change that by using the GLOBAL keyword though. Or by using the $GLOBALS array.


If I were you I'd probably have the ArtScheme function return an
array with the stuff in it you need.


Something like:

<?php


function ArtScheme($SchemeSelected){ 
switch($SchemeSelected) 
{ 
case "home": 
include ('homescheme.php'); 
break; 
default: echo "Your Color Scheme does not work"; 
} 

$colorArr = array('borderColor'=> $bordercolor, 
                  'highlightColor' => $highlightcolor );

return $colorArr;
} 

$SchemeNeeded = "home"; 
$colorVarsArr = ArtScheme($SchemeNeeded); 

?>

<table width="775" border="0" cellpadding="1" cellspacing="0" bgcolor="<?php echo $colorVarsArr['borderColor'];?>">

Or produce a number of css style sheet files and have PHP load up the one required.

Your function isn't returning anything. This would be a quick fix:

<?php 
function ArtScheme($SchemeSelected){ 
    switch($SchemeSelected) 
        { 
        case "home": 
        include ('homescheme.php'); 
        break; 
        default: echo "Your Color Scheme does not work";
        }
    return $color;
    }
?>
$SchemeNeeded = "home"; 
$color = ArtScheme($SchemeNeeded); 

<table width="775" border="0" cellpadding="1" cellspacing="0" bgcolor="<?php echo $color['border']?>"> 

<?php
// this in the include file
$colorscheme['home']['highlight'] = "#EBD7AB";
$color['border'] = "#CC9933";
$color['stripe'] = "#FFFFCE";
?>

And this is another, more compact, way:

<?php
include('colorschemes.inc.php');
$SchemeNeeded = "home"; 
$color = $colorscheme[$SchemeNeeded];
?>
<table width="775" border="0" cellpadding="1" cellspacing="0" bgcolor="<?php echo $color['border']?>"> 

<?php
// the below goes in the include file colorschemes.inc.php
$colorscheme = array(
    'home' => array('highlight' => '#EBD7AB', 'border' => '#CC9933', 'stripe' => '#FFFFCE'),
    'away' => array('highlight' => '#FFFF00', 'border' => '#FF0000', 'stripe' => '#CCCCCC')
    );
?>

No need for functions, just use the power of the array!

Well, and if I can be a pain, why not use CSS and load a different stylesheet?

Have fun with it!

Damn! Late again

Something else... what about a default style?

Here's a modification to the above example:

<?php
include('colorschemes.inc.php') 
$SchemeNeeded = "home";
if is_array($colorscheme[$SchemeNeeded]))
    {$color = $colorscheme[$SchemeNeeded];}
else
    {$color = $defaultcolors;}
?>
<table width="775" border="0" cellpadding="1" cellspacing="0" bgcolor="<?php echo $color['border']?>"> 

<?php
// the below goes in the include file colorschemes.inc.php
$colorscheme = array(
    'home' => array('highlight' => '#EBD7AB', 'border' => '#CC9933', 'stripe' => '#FFFFCE'),
    'away' => array('highlight' => '#FFFF00', 'border' => '#FF0000', 'stripe' => '#CCCCCC')
    );
$defaultcolors = array('highlight' => '#EEEEEE', 'border' => '#000000', 'stripe' => '#CCCCCC')
?>

But torrent is right, best way to do this is with CSS.
