Help with wordpress plugin, php

I'm new with PHP.

I have a wordpress plugin, which I just installed, that displays my designed zazzle's t-shirt on my website (powered by wordpress; self-host). It requires a shortcode, [zazzle rows="3" cols="3"], but that only works in the pages and posts. I want to place it on my website's template, just before the footer.php's first line, '</div>'. I tried to put its shortcode [zazzle rows="3" cols="3"] at footer.php & saved my amendment but it appeared as a text on my website. In other word, that shortcode doesn't work outside page (page.php) & post (post.php).

To help you help me, this is from the plugin's php (part of it):

// Shortcode handlers
add_shortcode('zazzle', 'zazzle_shortcode');
function zazzle_shortcode($atts) {
	$shortcode_atts = shortcode_atts(array(
		rows => 4,
		cols => 4,
		
	), $atts);

	return fetch_gallery($shortcode_atts);
}

Code (markup):

I want to create a php code something like this ... (below) ... so that I can place it on footer.php.

My proposed codes:

<?php if (function_exists('zazzle_shortcode')): ?>
<?php zazzle_shortcode('array(3,1)'); ?>
<?php endif; ?>

Code (markup):

or

<?php if (function_exists('zazzle_shortcode')): ?>
<?php zazzle_shortcode('rows="3" cols="1"'); ?>
<?php endif; ?>

Code (markup):

Obviously my proposed codes are wrong/not-functioning and hence, I am asking for your help. It could be very easy for you but isn't for me.

Many thanks in advance.

 

<?php
echo fetch_gallery(array('rows' => 3,'cols' => 3));
?>

PHP:

Try that

 

I think you should do this?

do_shortcode('[zazzle rows="3" cols="3"]');

PHP:

 

Yep, that is a better idea, go with that (although you might need to echo it too)

 

It seems to work! But currently, zazzle's server not responding, will try again later. Thank you guys.

<?php echo do_shortcode('[zazzle rows="3" cols="3"]'); ?>

Code (markup):

 

An update from me. It works!

Thank you very much, JAY6390 & ads2help!
