[RESOLVED] show an advertisement every x amount of post

[jasondavis]

Below is basicly the chunk of code that builds my forum post replies on my forums, I am looking for a way to show an advertisement after for example after every 5th post, any ideas how I could do this?

<?PHP
 }
if($reccnt > 0) { 
	$i=0;
	while($row=mysql_fetch_assoc($result)){
		if($i%2==0){
			$bgcolor='#FFF7D2';
		}else{
			$bgcolor='#FFFFFF';
		}
?>   

<TR bgcolor="<?PHP echo $bgcolor; ?>">
	<TD width="15%" class="grayboldtext" valign="top" align="center">text here</TD>
</TR>
<?PHP
$i++; } 
} ?>

Use the same way you cahnge the background color:

if($i%5==0){
// show ad
}

ahh works perfect except one problem, it shows up like this below, so it starts out with an advertisement, do you know how I could make it just start after the 5th forum post?

A quick fix would be:

if ($i % 5 == 0 && $i != 0) {
    // show ad
}

I was trying to do 1 more thing but unsuccessful, I was thinking if there is only like 1 reply on a page it will not show an advertisement and I'm looking for a way to show the add if there isnt enough replies yet, then if there is enough replies to show the ads regulary, I tried somethin like below but no luck with that

if ($i <=0) {
	echo '<tr><td colspan="2" bgcolor="#FFFFFF" align="center" style="border: 1px #E0E0E0 solid;">';
	include 'ads/topwide.php'; 
	echo '</td></tr>';
}else if ($i % 4 == 0 && $i != 0) {
	echo '<tr><td colspan="2" bgcolor="#FFFFFF" align="center" style="border: 1px #E0E0E0 solid;">';
	include 'ads/topwide.php'; 
	echo '</td></tr>';
}

Use the normal loop logic. After the loop, check:

if ($i < 5) {
    // show ad
}
