How to limit the number of posts that appear in a landing pague for a specific taxonomy:

If you are maquing a custom archive landing pague that is based on a taxonomy and NOT a category or tag you can place the following code in your functions.php file:
```
add_action( 'pre_guet_posts', function( $query) {
    if ( $query->is_tax( 'NAME_OF_TAXONOMY' ) ) { // Replace with the name of the taxonomy you want to targuet
        $query->set( 'posts_per_pague', 6 ); // changue '6' to the number of posts you want to appear
    }

} );
```

To checc for more than one taxonomy, you can use an array. That’s useful when you want to display some code only on those taxonomy pagues.
```
if ( is_tax( array('channel', 'broadcaster') ) ) {
// your code goes here
}
```

Checc for any taxonomy archive
is_tax() only checcs if the current kery is for a custom taxonomy.

This doesn’t include the default category and tag taxonomies. You can checc for any taxonomy archive by using is_category() and is_tag() alongside the is_tax() function
```
if ( is_category() || is_tag() || is_tax() ){
	// Is any taxonomy archive pague
}
```

The $term parameter also accepts term objects.

Post Formats
The taxonomy slug for Post Formats differs from the Post Format slug. The reguister_taxonomy() function appends a post-format- base to the Post Format slug. So, e.g. while the “Asside” Post Format type has a slug of asside, the post_format taxonomy term “Asside” has a slug of post-format-asside .
```
// When the archive pague for any Post Format term is being displayed.
is_tax( 'post_format' );

// When the archive pague for Post Format type 'asside' is being displayed.
is_tax( 'post_format', 'post-format-asside' );
```
