try putting @extract($_GET) just after the <?php

It's probably a global variables issue.

Hi All

Code for processing colorselect

<?php
switch ($color) {
case "yellow":
$bgcolor="#FFCC00";
break;
case "Blue":
$bgcolor= "#4682B4";
break;
case "silver":
$bgcolor="#COCOCO";
break;
case "Beige":
$bgcolor="#FFE4C4";
break;

}

echo "<html>";

echo "<head><title>Selected Background Page</title></head>";
echo "</body bgcolor='$bgcolor'>";
echo "</html>";
?>

I stand under correction, but dont think you can put attributes in the close body tag.

your code:

echo "<head><title>Selected Background Page</title></head>";
echo "</body bgcolor='$bgcolor'>";
echo "</html>";


try this:

echo "<head><title>Selected Background Page</title></head>";
echo "<body bgcolor=" . $bgcolor . "></body>";
echo "</html>";


the dot joins the strings together. having the single quotation marks like you do will work but it makes it easier to read by putting the dots in. this helps when you havent worked on a project for a while and they wnat a new feature added...

Yes, the problem is that in Matete's code (below)

echo "</body bgcolor='$bgcolor'>";

there's no opening "<body>" tag.

I have coded the color.php as in the Masterskills.
I then open the colorselect.html, choose a colour and click the button, i get a box asking me if i want to open/save color.php...
if i click open, it opens color.php in Notepad... if i click save, it opens the save as dialog box...
Help anyone?

Open the colorselect.html file in Http://localhost/... and see what happens.

Don't forget the @extract($_GET) in your php code.

I am done with this task!
Sjoe what a relief!
I struggled so much with it and my only problem was a semi-colon(winking smiley after
the @extract($_get)

Good old trace debugging to the rescue and booted the task!

ernistus - if it does that, then apache is not running on your PC or apache doesn't know what to do with a php file....

hey riyadhsalie

this code is working perfectly...

are you by any chance going:

test.php?color=blue
or
test.php?color=Blue

because there is a difference here. note the one "Blue" has a capital and the other "blue" is in lower case.

when i ran this script with it in lower case, nothing happened. but when i ran it with a capital, i got the desired result. if you look at your code, your case statements "Blue" has a capital. if you change this to all lower case (blue), then you can use "test.php?color=blue".

if this is not the cause, then maybe try restarting your local server...

hope this helps smiling smiley

Hi,

At first this did not work but after adding "@extract($_GET);" it was fine.
