Hey there, I would like to build something that functions much like the colour and txt size options on [a href=\"http://www.thefloatingfrog.co.uk/\" target=\"_blank\"]http://www.thefloatingfrog.co.uk/[/a]

I started with :

/*** CSS Colour Selector ***/
if (!$cselected) {
$css = $_GET[colour];
if(!strcmp($css, 'blue')) { $cur_colour="<link href=\"blue.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else if(!strcmp($css, 'orange')) { $cur_colour="<link href=\"orange.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
$cselected=1;
}

/*** CSS Text Size Selector ***/
if (!$tselected) {
$txt = $_GET[textsize];
if(!strcmp($txt, 'small')) { $cur_txt="<link href=\"small.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else if(!strcmp($txt, 'large')) { $cur_txt="<link href=\"large.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else { $cur_txt="<link href=\"medium.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
$tselected=1;
}

but as I am sure you see it does not work correctly... any ideas on how to fix this?

I found that the below works.. does anyone see anything here that could be improved?

/*** CSS Colour Selector ***/
if($css = $_GET[colour]) {
if(!strcmp($css, 'blue')) { $cur_colour="<link href=\"blue.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else if(!strcmp($css, 'orange')) { $cur_colour="<link href=\"orange.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else { $cur_colour="<link href=\"orange.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
$_SESSION['cselected']=$cur_colour;
}
else {
$cur_colour="<link href=\"blue.css\" rel=\"stylesheet\" type=\"text/css\" />";
$_SESSION['cselected']=$cur_colour;
}

/*** CSS Text Size Selector ***/

if ($txt = $_GET[textsize]) {
if(!strcmp($txt, 'small')) { $cur_txt="<link href=\"small.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else if(!strcmp($txt, 'large')) { $cur_txt="<link href=\"large.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
else { $cur_txt="<link href=\"medium.css\" rel=\"stylesheet\" type=\"text/css\" />"; }
$_SESSION['tselected']=$cur_txt;
}
else {
$cur_txt="<link href=\"medium.css\" rel=\"stylesheet\" type=\"text/css\" />";
$_SESSION['tselected']=$cur_txt;
}

Yes. You can replace all of the if-else-if statements with switch statements and you can delimit your strings with single quotes to eliminate the escaped double quotes:
[code]<?php
/*** CSS Colour Selector ***/
$selected_color = 'blue';  // default if $_GET['colour'] not set
if (isset($_GET['colour'])) {
    switch ($_GET['colour']) {
         case 'blue':
         case 'orange':
                $selected_color = $_GET['colour'];
                break;
         default:
                $selected_color = 'orange';
     }
}
$cur_colour = '<link href="' . $selected_color . '.css" rel="stylesheet" type="text/css" />';
$_SESSION['cselected']=$cur_colour;

/*** CSS Text Size Selector ***/

$text_size = 'medium'; // default text size if $_GET['textsize'] is not set
if(isset($_GET[textsize])) {
    switch ($_GET['textsize']) {
        case 'small':
        case 'medium':
        case 'large':
               $text_size = $_GET['textsize'];
               break;
         default:
                $text_size = 'medium';
    }
}
$cur_txt='<link href="' . $text_size . '.css" rel="stylesheet" type="text/css" />';
$_SESSION['tselected']=$cur_txt;
?>[/code]
Much cleaner, simpler, and easier to maintain. For example, if you want to add a new valid color (or colour), just add it the the list of case statements.

Thanx, but this does not seem to work the same way as what I posted.

If I pick Orange, and then pick a large txt size I end up losing the orange selection and am presented with Blue + Large txt

You're loosing one of the selections because, even though the selections are stored in session variables, they are not used. If the code is modified slightly to use the session variables, it should work as you intended.
[code]<?php
$selected_color = (isset($_SESSION'[cselected']))?$_SESSION['cselected']:'blue'; // default if $_GET['colour'] not set
// ...
$_SESSION['cselected']=$selected_color;
//
// and
//
$text_size = (isset($_SESSION['tselected']))?$_SESSION['tselected']:'medium'; // default text size if $_GET['textsize'] is not set
//...
$_SESSION['tselected']=$text_size;
//
?>[/code]
