ID Question

If I use a php script to loop an item listing template I have does that mean that the template cannot use ID's as it will be displayed more than once?

Do all the html elements need to be class's instead of ID's?

You could use ID's. What you could do is use some sort of variable that has an initial value of something like $1 = 1.

Then, you could use that on an ID element to make each unique by adding 1 to the counter each time it loops. For example:

<?php
$i = 0;
foreach($items as $item){
    $i = $i + 1;
    echo '<div class="someclass" id="someid-"' . $i . '">' . $item['title'] . '</div>'; 
};
?>

Basically, you are using an $i variable counter to increase by 1 each time the items loops through to make that individual item have a unique id.

Edited slightly, but this should so about what you are trying to accomplish.

I don't follow your question entirely. However, you can have multiple html elements with the same class. Any time the id attribute is used it must be unique to one html element.
