Filter a gallery

I use a template to list all images from a custom post type in a gallery with wp_query function, this works very well ;)

Now I want to add a subnav that functions as filter for the displayed images.

The subnav will show the different available categories for the Custom Post Type.

For example:

I have a Custom Post type of 'Cars' and this CPT has 4 categories: 'AUDI','BMW','FIAT' and 'VOLVO'

First of all if you click my View all cars template, you will see all the cars and now I want to add a subnav ('Filter gallery: ALL AUDI BMW FIAT VOLVO), that depending on the above button you click will update the gallery to show only the selected category!

Do I have to use jquery to achieve this? How do I trigger the button actions?

Thanks in advance,

Hello Steven,

I would take a look at the in_category explanation on the Codex.

The snippet is an example of where I am pulling different widget areas depending on the category of the post when looking at single.php. You should be able to emulate that on your Gallery to use a variable to set the category based off the button pressed.

 <?php if (in_category('3')) {get_sidebar('entertainment');} elseif (in_category('5')) {get_sidebar('functions');} else {get_sidebar('blog');} ?>
