A bug in front end search functionality?

We love your plugin!

I was trying today to get the font end search working for the EAN-14 numbers we’re entering into the back end.

I ticked the “Search (This will enable searching by EAN on frontend.)” checkbox of course but that didn’t work so I had a look under the bonnet.

I noticed in “ean-for-woocommerce/includes/class-alg-wc-ean-search.php” line 226 – 233 this code..

// Pre-check

if (

	! isset( $wp_query->query['s'] ) ||
	! isset( $wp_query->query['post_type'] ) || 'product' != $wp_query->query['post_type'] ||
	! apply_filters( 'alg_wc_ean_search', true, $wp_query )
) {
	return;
}

But “$wp_query->query[‘post_type’]” returns an array, not the post type itself. When I change the code, adding a “[0]” to the end of “$wp_query->query[‘post_type’]”, like this..

if (

	! isset( $wp_query->query['s'] ) ||
	! isset( $wp_query->query['post_type'] ) || 'product' != $wp_query->query['post_type'][0] ||
	! apply_filters( 'alg_wc_ean_search', true, $wp_query )
) {
	return;
}

The front end search starts working perfectly.

Did I find a bug or am just mis-configuring the plugin or tripping or something?
