New BB tag to do rainbow text...

[Zzed]

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.php?s=&threadid=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. :D

Note3: You can find the revised and BB code friendly version in this post (https://vborg.vbsupport.ru/showthread.php?postid=340386#post340386)

Note4: You can find the version that displays the full spectrum of colors in this post (https://vborg.vbsupport.ru/showthread.php?postid=342116#post342116).

Looks good;)

Please add your hack in a .txt file rather then showing it like this. Thank you.

[DrkFusion]

Hehe cool little hack :)

Drkfusion will install this

[vdinh]

Cool hack :) ... However, I have some problem with some unicode characters. They will show as #xxxx, not as the real unicode charaters. Would you please point out what should I do ?

I wonder if you can point me to a thread in your forums so that I can see what you are seeing. :)

Zzed, I figured out how to take the black background out but how do I make the rainbow text the same size that is set for the message? It is bigger than the regular message text.

Great hack, by the way. :)

Thank you Boofo. :)

Here is how you fix the font size. ;)

Change this line in dorainbow()


$buffer .= "<font color=\"$color\">";


To this:


$buffer .= "<font color=\"$color\" face=\"verdana,arial,helvetica\" size=\"2\">";

[Boofo]

That was quick. Thank you. :)

Here is what I changed to make the background transparent.

$buffer = "<table><tr><td bgcolor=\"\">";

It works, but is it the correct way to do it? :)

[corsacrazy]

is there a way to add this using the bb code adding option in the acp or do i have to edit my functions :(

[Zzed]

Boofo, You can actually leave out the bgcolor stuff and just use <td> by itself. ;)

corsacrazy, unfortunately to the best of my knowledge this is the only way to do it. :(

DOHH!!! :) I figured that out after I wrote the message. Sorry about that. The size change works great but I can not change the size of the text to anything else within the message now for some reason. :(

Ok, I assume you are talking about post #2 in that thread. I made a note in my original post that using BB code inside the rainbow tags will end up displaying the underlying HTML code, which is what you are seeing in there.

I can probably fix it. But it is not something that I can do any time soon. :(

[nymyth]

i installed this hack, but i dont see anything.......whats going on??

Peace

ps..i mean is there supposed to be an option that u press like php/list etc??

[Silenced Soul]

heh, pretty cool. I'll install it just for fun. :P

[bitbender]

Ok, I understand.. I wondered if I read past it before.... and I did..sorry.

[nymyth]

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

[KuraFire]

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!

[Zzed]

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.

[John]

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);
}

[Areku]

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!!

supercalifragilisticumspialidociousisthewordiuseto testthisrainbowthing

[Areku]

Oh!

It didn't work!!

DarkFusion, what did u use!? Manually entered that sentence colorfull?

[John]

Yes, he did (try quoting his post!)

[Areku]

I did quote his, still stunned he spent that much time!!

However there must be a way to add blue and green to the rainbow of this hack, isn't it??

[John]

There's always a way, but the maths would be more complicated.

Also jsut a reminder to people you will use J.Eovies mod, keep in mind that the glow style can be viewed by users using IE 5.5+ I am not sure about other browsers.

By the way its a secret :speechless:

[Areku]

So how many $$$ to reveal your trick Dfusion? ;)

I installed this and the only vbcode it would recognize and use was the FONT code. The size and nothing else works with it. What is the difference between this version and the first version you posted? And is there a way to get the whole color spectrum (like in Drks replies)? Also, is there a way to have it default to the board set font size instead of having to hard code it to size 2?

[John]

I found a bit of a flaw in this - when you type in a lot of text, you can see the backslashes for " cancelling and line breaks:

Nice, won't install it though ;)

I might install it, thanks!

I went ahead and made a new version that looks like DrkFusion's posts. Here is an example. I will release it in this thread for anyone who is interested.

[Boofo]

I'm interested. Send it up, sir. :)

Will they still make the rainbow wider as you add more text or will it start the rainbow effect over again after so much text? The second option would actually be better, if it can be done, that is. :)

[nymyth]

im interested...how can i get it...thanx

It widens as your text gets longer. ;)

We are waiting man. Glad you are helping with this.

Here is the version with the full spectrum of colors.

Zzed, I couldn't do the new version with the following line:

$bbcode=str_replace("{", "{", $bbcode); // stop people posting replacements in their posts

Because my line for that is this:

// $bbcode=str_replace("{", "{", $bbcode); // stop people posting replacements in their posts

because of another hack. I just changed the "// ###################### Startdorainbow #######################" part and left the first part from version 1 in there instead. It seems to work. ;)

LOL That was already done (with a little less glow effect, which looks better) in the beginning of the thread. What else was changed, maybe I missed it?

I get a division by zero error every time someone types in without anything in it. The error only appears on the page at which it's typed but doesn't go away, it just accumulates over time. Otherwise the hack works perfectly, but it's that error which is stopping me from installing it, as not all members are kind enough to NOT type it in. :( And way to stop this?

I fixed all 3 versions. ;)

In function dorainbow()
Look for:

Add this directly below it:
