dynamic color selector

**Zac** · June 11, 2007

I was trying to create a dynamic color selector using php....

I uploaded it here: http://www.theneopianoutpost.com/new/index.php

I get this error: Parse error: parse error, unexpected T_STRING in /home/content/I/n/d/Individual12/html/new/index.php on line 29

Heres my coding: (Note: Do not try to figure this out if you don't know php or else you'll hurt your head :P)

<?php
function hsb( $h, $s, $v )
{
 $r = $g = $b =0;
 if ( $s==0 )
 {
$r = $g = $b =$v;
 }
 else
 {
$h = $h / 60;
$i = floor( $h );
$f = $h - $i;
$p = $v * ( 1 - $s );
$q = $v * ( 1 - $s * $f );
$t = $v * ( 1 - $s * ( 1 - $f ) );
switch( $i ) {
case o: $r = $v; $g = $t; $b = $p; break;
case 1: $r = $q; $g = $v; $b = $p; break;
case 2: $r = $p; $g = $v; $b = $t; break;
case 3: $r = $p; $g = $q; $b = $v; break;
case 4: $r = $t; $g = $p; $b = $v; break;
default: $r = $v; $g = $p; $b = $q; break;
}
 }
 return array( $r, $g, $b );
}

functiom hsb2hex( $h, $s, $b )
{
  list( $r, $g, $b ) = hsb( $h, $s, $b );
  return sprintf( "#%02x%02x%02x", $r, $g, $b );
}
?>
<html>
<head>
<script language="Javascript">
function mover( id )
{
 var obj = document.getElementById( id );
 obj.style.borderColor = "white";
}
function mout( id )
{
 var obj = document.getElementById( id );
 obj.style.borderColor = "black";
}
function selectColor( color )
{
 document.getElementById( "hoverColor" ).innerHTML = color;
}
</script>
<style type="text/css">
body { font family: arial, verdana, sans-serif; }
#color { font-family: courier }
#hoverColor { font-family: courier; }
</style>
</head>
<body>
Color: <input id="color" type="text" size="8" />
<table cellspacing="10" cellpadding="0"><tr><td>
<table cellspacing="0" cellpadding="0">
<?php
$id = 1;
for( $h = 0; $h < 360; $h += 18 ) { ?>
<tr>
<?php for( $b = 255; $b >= 0; $b -= 10 ) {
$color = hsb2hex( $h, $b / 255, $b );
?>
<td>
<div id="cp<?php echo( $id ); ?>" style="height:10px; width:10px; border: 1px solid white; background:<?php echo( $color ); ?>;" onmouseover="mover('cp<?php echo( $id ); ?>');hover('<?php echo( $color ); ?>');" onmouseout="mout('cp<?php echo( $id ); ?>')" onclick="selectColor('<?php echo( $color ); ?>');"</div>
</td>
<?php
$id += 1;
} ?>
</tr>
<?php } ?>
</table>
</td><td valign="top">
<div id="hoverColor"></div>
</td></tr></table>
</body>
</html>

Any ideas why its not working?

Error on line 29...

which is :

functiom hsb2hex( $h, $s, $b )

and should be

function hsb2hex( $h, $s, $b )

so just a typing error, I think...

I'm curious. I use frontpage and I followed a tutorial on another website on how to use PHP with FP, but it didn't work. What program are you using to code your PHP?

I write my php on notepad and use SmartFTP to upload it...

D'oh! Thanks for the help Angelxepha! ((stupid typo <_<))

You are welcome Zac :P

And usually, well, I dont code much in PHP... but I would do it in notepad or viewing source code in dreamweaver...
