Hi John and thanks for your quick reply!
Please let me know if I got it right – the htaccess redirection code above has no mistakes and it should work under normal circumstances?

Hello Sayontan!

Just in case you interested, i have found a nice way to use dropdown in an attachement categories gallery page using URL query strings. It utilises the wordpress function ‘wp_dropdown_categories’ and a short script right in the gallery page-id.php. Here is the code:

<?php $linkParam = sanitize_text_field( $_GET['acat'] ); 
 wp_dropdown_categories(array(
	'id'				=> 'drop',
	'exclude'			=> '2395',
    'hierarchical'		=> true,
    'order'				=> 'ASC',
    'orderby'			=> 'name',
    'show_count'		=> 1,
    'show_option_none'	=> 'Choose a category',
    'taxonomy'			=> 'attachment_category',
    'selected'			=>  $linkParam, ) );  ?>

<script>
	let dropdown = document.getElementById('drop');  
	let selIndex = new URL (window.location.href).searchParams.get('acat'); 
	dropdown.addEventListener("change", onCatChange); 

function onCatChange() { 
	let selIndex = dropdown.options[dropdown.selectedIndex].value;
	location.href ="look?acat="+selIndex; } 
</script>

<?php echo do_shortcode('[gallery style="random" category="' . $linkParam . '" main_size="full" order="DESC" orderby="ID" tile_size="full" link="file"]');?>

It works perfectly with the Media Library Categories plugin. It also works fine when the gallery page is opened by an external link with a query string ‘?acat=X’ where X is the ID of the category you want the gallery page to show.
Thank you once again for your kind assistance, it really helped me to resolve the problem. Have a good day!

I found out that accordions are based on CSS display:block/none and tested the feature. A display:none gallery loads as fast as a blank page and only starts loading images after selecting “display:block”. So, as far as I can tell, the idea works fine and I can use it with my dropdown.
Thank you again!

Thanks for the tip!
I just trying to device a simple solution to print galleries on a page using dropdown where a user could select and see different attachment categories from my media library.
For now I coded a dropdown using JS, but still have no idea how to use it to change category value in shortcode.
I’m not sure if I should ask your advice on it in this topic though.

I found the cause of the problem, it was my mistake – I just forgot to load the footer in the page-php. Everything work fine now, sorry to bother you with trifles.

I understand, no problem, thanks!

Another question, if you don’t mind. I print a gallery directly from a page-id-template like so:
<?php echo do_shortcode('[gallery category="200"]'); ?>
and everything goes fine, but as soon as I change it to
<?php echo do_shortcode('[gallery category="200" style="random"]'); ?>
I get a blank area instead of the page content.
Interesting that when if I’m moving a mouse over the blank area I can see the gallery links in the left bottom corner of the browser. The links open in a new page on click, as if the gallery plugin wasn’t there at all. The same Photonic code works fine inside the page.
Is there a way to print Photonic gallery using PHP or may be JS?

Sorry, that was my mistake! I found that I was using “attachment_category” instead of just “category” shortcode. With the latter everything works fine.
PS – it’s weird that [gallery] works with the wrong option at all, so I didn’t notice it right away.

Thank you for your lightning fast reply!
#1 – are you planning to add the Mosaic Trigger width and Random Tile height options for individual gallery shortcode?
#2 – tile_size option works perfectly, thanks!
