Hi there,

I'm relatively new to Processwire (and PHP!) and have the following question:

I'm currently looping through the images field as shown below:

foreach($page->images as $image) {
					$large = $image->size(1200, 795);
					echo "{$large->url},";
				}

You'll notice that there is a comma after the {$image->url}. I would like to be able to check in the loop if it is the last image and if so, the comma is not shown. Would appreciate the help!

Cheers,
Sev

Hi sev and welcome!

You could do the following and strip the last char from the string after the loop.

<?php
// if there's any images
if(count($page->images)){
	$out = '';
	foreach($page->images as $image) {
		$large = $image->size(1200, 795);
		$out .= "{$large->url},";
	}
	echo substr($out, 0, -1);
}

Works perfectly – Thanks Soma!
