Php List Help

[driz]

Hi please take a look at this website: http://hermes.hud.ac.uk/u0558234/mediadrop/The images in the middle are created using UL and LI's the first of each three LI's has a class of "first"My problem is that this list will be displayed using PHP, how can I get it so that when my list is shown, the first li of every 3 li's will have a class of "first"?The list will be shown using a simple echo '<li>$row</li>' variable from an MySQL database.Thanks

You should be able to keep track of which item you're printing. You can use a counter for that, or even just a boolean to say whether or not it's the first one.

Hi, thanks for the reply. Would you be able to post an example please, I learn better when I can see the actual code and see how its constructed. Thank you.

[justsomeguy]

$first = true;foreach ($list as $item){  if ($first)	echo '<li class="first">';  else	echo '<li>';  $first = false;  ...}

<?php					$host="localhost";					$username="u0559023";					$pass="02dec86";										mysql_connect($host,$username,$pass);					mysql_select_db($username);										$query="SELECT name, work_location  FROM Portfolios, Work WHERE Portfolios.portfolio_id = Work.portfolio_id";					$result=mysql_query($query);					echo "<ul id='home-recent-work'>";										$first = true;									while($row = mysql_fetch_array($result)){													  if ($first)							echo '<li class="first">';						  else							echo '<li>';						  $first = false;										  										echo "<h3>".$row['name']."</h3>";						echo "<a href='profile.php?name=".$row['name']."'><img src='".$row['work_location']."'/></a></li>";										}											echo "</ul>";					mysql_close();										?>

This is what I have so far, it will add the class to the first LI right? How do I get it so it adds it to the first of every 3 LI'sSo I get this effect:

<li class="first"></li><li></li><li></li><li class="first"></li><li></li><li></li><li class="first"></li><li></li><li></li>

I take it I'm going to need a count to do this? Can you please show an example of how I could do this thanks

[justsomeguy]

$nr = 0;while (){  if (!($nr++ % 3))	echo '<li class="first">';  else	echo '<li>';  }

[driz]

shouldn't that be?

if (!($nr++ % 3)) {	echo '<li class="first">';}  else{	echo '<li>';}

[justsomeguy]

That's the same thing, brackets aren't necessary if a control structure only has a single statement.

[Ingolme]

shouldn't that be?

if (!($nr++ % 3)) {	echo '<li class="first">';}  else{	echo '<li>';}

Braces are not needed if there is only a single line of code after the if() statement.
