Rainbow Username

[Black Snow]

Hi,

Can anyone tell me why this won't work? It's for creating rainbow usernames but for some reason it doesn't work.

if( strpos( $user['musername'], 'rainbow: true;' ) !== false ) 
{ 
    $i = $b = 0; 
     
    $username = ''; 

    $colours = array('d31539', 'ff7e00', 'ffc20e', '90d125', '187acb', '6f3198', 'ab1d8e'); 

    while( $i < strlen( $user['username'] ) ) 
    { 
        if( $b > ( count( $colours ) - 1 ) ) $b = 0; 
         
        $username .= '<span style="color: #' . $colours[ $b ] . '">' . $user['username'][$i] . '</span>'; 
         
        ++$b; 
        ++$i; 
    } 
     
    $user['musername'] = '<strong>' . $username . '</strong>';

I also made the usergroup HTML markup to:

<strong style="color: #FFBC58; rainbow: true;">

</strong>

You have to split the string up into an array. Here's what I got working:

function rainbow($str)
{
	$array = str_split($str);    
        $i = $b = 0;
        $str = '';
        $colours = array('d31539', 'ff7e00', 'ffc20e', '90d125', '187acb', '6f3198', 'ab1d8e'); 
        while( $i < count($array) ) 
        { 
                if( $b > ( count( $colours ) - 1 ) ) $b = 0; 
                 
                $str .= '<span style="color: #' . $colours[ $b ] . '">' . $array[$i] . '</span>'; 
                 
                ++$b; 
                ++$i; 
        }
        return $str;
}

What hook location did you use? Could you post a screenshot of it?

For some reason, it turns quite a lot of my text a yellow colour but no rainbow effect.

I found that the code you posted in post #1 works using hook fetch_musername, but you're just missing a closing '}' at the end.

Could you post a screenshot if it working? I used the code that nerbert posted with the same hook location you mentioned and it didn't work.

Edit: Got it working. You can close this thread.
