What's Wrong With My Code?

[noonespecial]

Some examples:

random, staff, inside

random

drew

NULL

tags varchar(255) latin1_swedish_ci Yes NULL

From PHPMyadmin, if this helps.

PHP Code:

$entrys = $db->query_read("SELECT * , tags IS NULL AS isnull FROM " . TABLE_PREFIX . "journal_entries WHERE journal_id =" . $vbulletin->GPC['j']." ORDER BY isnull ASC, tags ASC");    
        
while ($entry = $db->fetch_array($entrys))
{
        
if ($entry['tags'])
    {
        $kwords = explode(',', trim($entry['tags']));
        $entry['tags'] = '';
        foreach ($kwords AS $keyword)
        {    
        $keyword = trim($keyword);
        $entry['tags'] .='<a href="/journal.php?' .$vbulletin->session->vars['sessionurl']. 'do=showjournal&amp;tag='.$keyword.'&amp;j='.$j.'">' .$keyword. '</a>, ';
            
        }
        $entry['tags']= substr_replace($entry['tags'],'',-2);
    }
} 


Also doesn't work.

Edit:

Do I need to somehow add "commas" to the end of the other values?

I am so lost..

Someone, please help.
