random cell color

cmac

Greetins,

i hacked this code together but i get an error. what i would like to do is for a specific cell i would like to dynamically generate random colors when the browser gets refreshed. Is there any sence to the code below? I found the below code to generate random color for fonts. I thought it would just as easy to change the tag to being a cell. I could really use someone's guidence.

<?
$colors[0] = "#000000"
$colors[1] = "#000033"
$colors[2] = "#000066"
$colors[3] = "#000099"
?>
<TD width="100%" align="center" bgcolor="<? echo($colors[$rndNum]); ?>">

Thanks in advance.

swr

I would guess $rndNum is not set. Try this for the echo:
echo $colors[array_rand($colors)];

If you want really random colors, try this instead:

Thanks for the quick reply. It didnt seem to work for me. Is there another piece that i am missing? I think i would like to build an array just have a bit of control. Thanks for looking at this is is MUCH appreciated

This is the error i get in my browser:

Parse error: parse error, unexpected T_VARIABLE in G:\HTML_WorkingFiles\Data\demo2.php on line 10

Here is my code:

You might try adding semi-colons to the end of the lines where you declare your variables 😉

uhh, it doesn't work? whats the problem exactly? Colours always the same? You getting errors? Or you just don't see anything? If you don't see anything you might try adding content to the cell. But yea, work for me!

Im sooo sorry. your right the color is always the same. Dark Blue. I dont get any scripting errors. each time i refresh its the same thing. Thoughts?

cmac

im soo sorry. It does work. My poor eyes wasnt able to see the difference.

THanks sooooooooooooooo Much.

Really? You refreshed many times? Sometimes it may randomly choose the same one. But if it's always the same I don't know, works fine for me!
