Random hex color

Hello,

I have some PHP code that generates a random hex color code. I would like to incorporate it for use in vbulletin (it has to be server side). In a normal PHP file, the output is something like $randomcolor.

Does anyone know how to get that to be displayed properly within VB using the plugin system (if that's the proper way to do it)?

Stick the PHP code in a new plugin using the "global_start" hook. $randomnumber should then be available to use in most templates.

Best way is to put the code in a plugin for global_start and then call the variable you are using for it wherever you want to use it.

wow, fast replies, many thanks.

Is it simply called with $randomnumber ? Or does it need some {} or [] ?

We can't tell you without seeing your code.

OK, the code I plan on using is from here:

http://www.zend.com/tips/tips.php?id=243&single=1

My rendition is below:

Code:

<? 



// randomize the color 

$r = rand(128,255); 

$g = rand(128,255); 

$b = rand(128,255); 



$randomcolor = dechex($r) . dechex($g) . dechex($b); 

?>

Okay, in your plugin, do NOT include the PHP tags (<? and ?>). Everything else looks okay - be sure to add the # in front of $randomcolor when you use it. And no, you won't need any []s or {}s.

OK, thanks again for the quick reply. I'm trying to use it in the postbit_legacy to display in posts, but nothing is showing.

Should I call it differently for there?

Posts are processed in a function, so it's not available there. If you want every post to have a different color, do this: hook: postbit_display_complete

PHP Code:


		
			
$r = rand(128,255); 
$g = rand(128,255); 
$b = rand(128,255); 

$randomcolor = dechex($r) . dechex($g) . dechex($b);

and then $randomcolor will be available (and unique) in all of your posts (you can remove the other plugin you created in global_start).

If you want them all the same:
postbit_display_complete

PHP Code:


		
			
global $randomcolor;

(while leaving the original global_start hook intact).

Fantastic! My deepest thanks. I'm actually using as part of an included JS script that needs an image border color and it works well now! Thanks!
