Exclude category in blog posts

Hi,

I selected all the categories but the one I want to exclude.

Did you select the parent categories? It should display only the items from the selected category unless the parent category of the child categories where the posts belong to are selected.

Hi,

Thanks for the update. This filter might help:

// exclude meat
add_filter('avia_blog_post_query', 'avia_blog_post_query_mod', 10, 2);
function avia_blog_post_query_mod($query, $params) {	
	$query['tax_query'][] =
        [
            'taxonomy' => 'category',
            'field'    => 'name',
            'terms'    => 'meat',
            'operator' => 'NOT IN',
        ];

    return $query;
}

Hi,

You can use the is_page conditional function if you want this modification applied to a specific page. And change the value “meat” to an array if you need to exclude multiple categories.

Hi,

The code should look something like this:

// exclude categories
add_filter( 'avia_blog_post_query', 'avia_blog_post_query_mod', 10, 2 );
function avia_blog_post_query_mod($query, $params) {
    if( is_page('home') ) {
        // exclude meat category when the current page is "home"
        $query['tax_query'][] =
        [
            'taxonomy' => 'category',
            'field'    => 'name',
            'terms'    => 'meat',
            'operator' => 'NOT IN',
        ];
    }	

	 if( is_page('fish') ) {
         // exclude an array of categories on the "fish" page
        $query['tax_query'][] =
        [
            'taxonomy' => 'category',
            'field'    => 'name',
            'terms'    => array('meat', 'vegetables', 'fruits'),
            'operator' => 'NOT IN',
        ];
    }	

    return $query;
}

Hi,

Thanks for the update.

Is “home” the actual slug or name of your home/front page? Try is_home instead of is_page or use the actual name or id of your home page.
