php if then statements

if one statement is true then several others are true

[Driven]

Hello all,

I'm trying to define several different styles in my web page based on one variable in the query string. So if I have www.mysite.com/index.php?style=1 then I want table cells to be a certain color, links to be a certain color, etc. Obviously style=2 would be a different color scheme.

I have the following code but it doesn't seem to work.

<?php
$style = $_GET['style'];
if ( $style == 1 ) {
$border = 336699;
$bg = FFFFFF;
$links = 0000FF;
$url = 008000;
$text = 000000;
$footer = FFFFFF;
}
if ( $style == 2 ) {
$border = 000000;
$bg = F0F0F0;
$links = 0000FF;
$url = 008000;
$text = 000000;
$footer = FFFFFF;
}
?>

It produces "Parse error: parse error, unexpected T_STRING in /home/drivenin/public_html/partners/style.php on line 12"

Can anyone help me with this? Please let me know if you need furhter info.

Thanks,
Dan

Welcome to WebmasterWorld Driven,

it's because you are missing your quotes

if ( $style == 1 ) {
$border = '336699';
$bg = 'FFFFFF';
$links = '0000FF';
$url = '008000';
$text = '000000';
$footer = 'FFFFFF';
}

if ( $style == 2 ) {
$border = '000000';
$bg = 'F0F0F0';
$links = '0000FF';
$url = '008000';
$text = '000000';
$footer = 'FFFFFF';

try that

The values you've assigned the variables aren't quoted, so the PHP parser is expecting a constant value (unless that value is actually a number).

Try:

$style = (int)$_GET['style'];

switch($style)
{
case 1:
$border = '#336699';
$bg = '#FFFFFF';
$links = '#0000FF';
$url = '#008000';
$text = '#000000';
$footer = '#FFFFFF';
break;

case 2:
$border = '#000000';
$bg = '#F0F0F0';
$links = '#0000FF';
$url = '#008000';
$text = '#000000';
$footer = '#FFFFFF';
break;
}

(I've also typecast the $_GET variable so it will only return an integer, and put your options into a switch statement, which will make it easier to read as you add more styles)
