for loop with count from array, limit output? PHP
- by Philip
print '<div id="wrap">';
print "<table width=\"100%\" border=\"0\" align=\"center\" cellpadding=\"3\" cellspacing=\"3\">";
for($i=0; $i<count($news_comments); $i++)
{
print '
<tr>
<td width="30%"><strong>'.$news_comments[$i]['comment_by'].'</strong></td>
<td width="70%">'.$news_comments[$i]['comment_date'].'</td>
</tr>
<tr>
<td></td>
<td>'.$news_comments[$i]['comment'].'</td>
</tr>
';
}
print '</table></div>';
$news_comments is a 3 diemensional array from mysqli_fetch_assoc returned from a function elsewhere, for some reason my for loop returns the total of the array sets such as [0][2] etc until it reaches the max amount from the counted $news_comments var which is a return function of LIMIT 10. my problem is if I add any text/html/icons inside the for loop it prints it in this case 11 times even though only array sets 1 and 2 have data inside them. How do I get around this?
My function query is as follows:
function news_comments()
{
require_once '../data/queries.php';
// get newsID from the url
$urlID = $_GET['news_id'];
// run our query for newsID information
$news_comments = selectQuery('*', 'news_comments', 'WHERE news_id='.$urlID.'', 'ORDER BY comment_date', 'DESC', '10'); // requires 6 params
// check query for results
if(!$news_comments)
{
// loop error session and initiate var
foreach($_SESSION['errors'] as $error=>$err)
{
print htmlentities($err) . 'for News Comments, be the first to leave a comment!';
}
}
else
{
print '<div id="wrap">';
print "<table width=\"100%\" border=\"0\" align=\"center\" cellpadding=\"3\" cellspacing=\"3\">";
for($i=0; $i<count($news_comments); $i++)
{
print '
<tr>
<td width="30%"><strong>'.$news_comments[$i]['comment_by'].'</strong></td>
<td width="70%">'.$news_comments[$i]['comment_date'].'</td>
</tr>
<tr>
<td></td>
<td>'.$news_comments[$i]['comment'].'</td>
</tr>
';
}
print '</table></div>';
}
}// End function
Any help is greatly appreciated.
