foreach PHP something wrong - php

Question

I have this code in PHP
<?php foreach($this->group('filter') as $i => $fields): ?>
<?php $newField = $this->field('name#'.$i)->value(); ?>
<?php $finalvar = explode(",", $newField); ?>
<a data-filter=<?php foreach($finalvar as $fletter) : ?>".filter_<?php echo standardize($fletter); ?>">
<?php endforeach; ?>
<?php if($this->field('icon#'.$i)->value()): ?><i class="<?php echo $this->field('icon#'.$i)->value(); ?>"></i><?php endif; ?>
<span class="name"><?php if($this->field('label_items#'.$i)->value()): ?><?php echo $this->field('label_items#'.$i)->value(); ?><?php else: ?><?php echo $this->field('name#'.$i)->value(); ?><?php endif; ?>
</span>
</a>
<?php endforeach; ?>
PHP code works but I have a problem on the HTML code. The generated HTML code is this:
<a data-filter=".filter_country">
".filter_capital;
<span class="name">Australia</span>
</a>
My goal is to implement this one:
<a data-filter=".filter_country,.filter_capital"
<span class="name">Australia</span>
</a>
I know it's something in front of me but I cannot see it. Does anyone have an idea concerning the syntax?

Check your syntax:
<?php foreach ($this->group('filter') as $i => $fields) : ?>
<?php $newField = $this->field('name#' . $i)->value(); ?>
<?php $finalvar = explode(",", $newField); ?>
<a data-filter="
<?php
$i = 1;
foreach ($finalvar as $fletter) { ?>
.filter_<?php echo standardize($fletter); ?>
<?php if ($i < count($fletter)) { ?>, <?php } ?>
<?php $i++; } ?>
">
<?php if ($this->field('icon#' . $i)->value()) : ?><i class="<?php echo $this->field('icon#' . $i)->value(); ?>"></i><?php endif; ?>
<span class="name"><?php if ($this->field('label_items#' . $i)->value()) : ?><?php echo $this->field('label_items#' . $i)->value(); ?><?php else : ?><?php echo $this->field('name#' . $i)->value(); ?><?php endif; ?>
</span>
</a>
<?php endforeach; ?>
