New BB tag to do rainbow text...

This is a fairly simple hack that allows you to create a new BB tag to do
rainbow colors with text. It is only a few lines and the only file affected
by it is admin/functions.php.

You can see a sample output in this thread: http://www.ls1.com/forums/showthread...hreadid=225576


Note1: This hack has been done and tested on VB 2.2.9
Note2: Using other BB tags within the rainbow tags will convert the underlying HTML code in to rainbow text.

Note3: You can find the revised and BB code friendly version in this post

Note4: You can find the version that displays the full spectrum of colors in this post.

well the code works....when i put in [ rainbow]text here[ /rainbow]

my question is do i have to do this manually each time....????or is there a drop down menu im missing??

Peace

oh god....

*winces*

What a lovely idea.. make the sourcecode of already huge threads even twice as big! :up:

Use five hundred font tags in a page! :up:

Double your bandwidth usages if people use your lovely (</sc>) hack! :up::up:

ugh...
(sorry, just felt like pointing that out ^_^)

Can you, DarkFusion, or anyone, explain me how to get the rainbow to act like HERE and not like the original hack? the original hack is lack of green and blueish colors of the rainbow...

Tu!

Ok, here is the BB code friendly version.

Note: If you have installed the original version, you need to back out of it and replace it with this one.

I made a couple of changes to this - I didn't much like the black background, so I went for the dark glow option. (See attached screenshot)

[John]

To use glow like I did, simply modify the code from the hack in the first post:

Find (in functions.php):

// ###################### Startdorainbow #######################
function dorainbow($code) {
  $len = strlen($code);
  $buffer = "<table><tr><td bgcolor=\"#000000\">";
  $mul = 255/$len;
  for($x = 0;$x < $len;$x++) {
    $color_h1 = 255*sin($x/($len/3));
    $color_h2 = $mul * $x;
    $color = sprintf("#FF%02X%02X", $color_h1, $color_h2);
    $buffer .= "<font color=\"$color\">";
    $buffer .= substr($code,$x,1);
    $buffer .= "</font>";
  }
    $buffer .= "</td></tr></table>";

  return($buffer);
}

And replace with:

// ###################### Startdorainbow #######################
function dorainbow($code) {
  $len = strlen($code);
  $buffer = "<table style=\"filter:glow(color=black, strength=2)\"><tr><td>";
  $mul = 255/$len;
  for($x = 0;$x < $len;$x++) {
    $color_h1 = 255*sin($x/($len/3));
    $color_h2 = $mul * $x;
    $color = sprintf("#FF%02X%02X", $color_h1, $color_h2);
    $buffer .= "<font color=\"$color\" face=\"Verdana\" size=2><b>";
    $buffer .= substr($code,$x,1);
    $buffer .= "</b></font>";
  }
    $buffer .= "</td></tr></table>";

  return($buffer);
}

FAR FAR Much nicer now with the glow effect!

However how do i add the FULL range of colors and not just the red/yellow/pink ones?

Blue and green are missing from the spectrum!!

No idea!

This code is pretty clever stuff, I can't figure it out!

[Areku]

What a weirdo!

Full range of colors is active here!!
