Recommended Posts

Ok so i have been playing with my site for a while and getting there very slowly... but heres the rub i am DYSLEXIC and am having issues following a tutorial and the code therein... the tutorial / code is over at http://www.scriptplayground.com/tutorials/php/Tag-Cloud/ and  where i am at is

[code]
<html>
<head>
<style type="text/css">
.tag_cloud { padding: 3px; text-decoration: none; }
.tag_cloud:link  { color: #81d601; }
.tag_cloud:visited { color: #019c05; }
.tag_cloud:hover { color: #ffffff; background: #69da03; }
.tag_cloud:active { color: #ffffff; background: #ACFC65; }
</style>
</head>

<body>
<?php
function get_tag_data() {
$host = "localhost";
$dbname = "###";
$dbuser = "###";
$dbpass = "###";

$connection = mysql_connect($host, $dbuser, $dbpass) or die(mysql_error());
$db = mysql_select_db($dbname) or die(mysql_error());

  $result = mysql_query("SELECT uid ,firstname ,lastname FROM user ORDER BY uid DESC limit 20");
  while($row = mysql_fetch_array($result)) {
    $arr[$row['firstname, lastname']] = $row['count'];
  }
  ksort($arr);
  return $arr;
}

function get_tag_cloud() {

$min_font_size = 100%;
$max_font_size = 250$;

$tags = get_tag_data();
$minimum_count = min(array_values($tags));
$maximum_count = max(array_values($tags));
$spread = $maximum_count - $minimum_count;

if($spread == 0) {
    $spread = 1;
}

$cloud_html = '';
$cloud_tags = array(); // create an array to hold tag code
foreach ($tags as $tag => $count) {
$size = $min_font_size + ($count - $minimum_count)
* ($max_font_size - $min_font_size) / $spread;
$cloud_tags[] = '<a style="font-size: '. floor($size) . 'px'
. '" class="tag_cloud" href="http://www.mouse.nodstrum.com/full_profile?u$uid . '" title="\'' . $firstname $lastname . '\' profile">'
. htmlspecialchars(stripslashes($tag)) . '</a>';
}
$cloud_html = join("\n", $cloud_tags) . "\n";
return $cloud_html;

?>

//Here is some example HTML to call this tag builder.
<h3>Sample Tag Cloud results</h3>
<div id="wrapper"
<!-- BEGIN Tag Cloud -->
<?php print get_tag_cloud(); ?>
<!-- END Tag Cloud -->
</div>

</body>
</html>
[/code]

okay, so it is only likely to be a missing ; or me mixing $uid and $did <b>BUT</b> if anyone can help i would be most appreciative

many thanks

Mouse
sorry should have said... error message says

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/nodstrum/public_html/mouse/xxxtag.php on line 51

thats the one that starts . '" class="tag_cloud" href="http://
You forgot a period between $firstname and $lastname.
[code=php:0]
$cloud_tags[] = '<a style="font-size: '. floor($size) . 'px'
. '" class="tag_cloud" href="http://www.mouse.nodstrum.com/full_profile?u$uid . '" title="'' . $firstname . $lastname . '\' profile">'
. htmlspecialchars(stripslashes($tag)) . '</a>';[/code]



EDIT: And you have your quotes mixed up around uid. I'm guessing it's suppose to be like this..
[code=php:0]$cloud_tags[] = '<a style="font-size: '. floor($size) . 'px'
. '" class="tag_cloud" href="http://www.mouse.nodstrum.com/full_profile?u=' . $uid . '" title="'' . $firstname . $lastname . '\' profile">'
. htmlspecialchars(stripslashes($tag)) . '</a>';[/code]
