Exclude custom post type category from homepage

    Hi there,

    I am trying to exclude a custom post_type category from displaying on the homepage. I am half way there…

    If I remove the <if> statements in the following code it works perfectly but I need them otherwise the function is applied to all pages in the site, not just the home page.

    I have a static front page configured.

    This is the code I have been trying to use:

    add_action('pre_get_posts','exclude_cat');
function exclude_cat( $query ) {
	if ( !is_admin() && $query->is_main_query() ) {
		$tax_query = $query->get( 'tax_query' ) ?: array();
		$tax_query[] = array(
			'taxonomy' => 'st_category',
			'field'    => 'id',
			'terms'    => array( 115 ),
			'operator' => 'NOT IN',
		);
		$query->set( 'tax_query', $tax_query );
	}
	return $query;
}

    I have also tried the following <if> statements with no success:

    if( $query->is_page( array( 113, 'portfolio', 'Portfolio' ) ) ) {

    if( $query->is_home() ) {

    if( $query->is_front_page() ) {

    What is going on?

    Please help if you can – thank you so much!

    Hello Bytelab,

    try ($query->query_vars[‘page_id’] == 113) as the first condition. is_front_page() does not work, because pre_get_posts runs before WP_Query has been setup (https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts).

    Hi buntegiraffe – thanks so much.

    I have tried the following based on your suggestion but again it just renders the function seemingly obsolete and shows all posts again rather than excluding those with the post_type category id of 115.

    add_action('pre_get_posts','exclude_cat');

function exclude_cat( $query ) {
        if($query->query_vars['page_id'] == 113) {
		$tax_query = $query->get( 'tax_query' ) ?: array();
		$tax_query[] = array(
			'taxonomy' => 'st_category',
			'field'    => 'id',
			'terms'    => array( 115 ),
			'operator' => 'NOT IN',
		);
		$query->set( 'tax_query', $tax_query );
	}
	return $query;
}

    I am really lost as to why this is happening… no doubt something simple though.
    If you have any further ideas I will be very grateful.

    Thanks!

    Success! I have found a solution using get_the_ID() …

    add_action('pre_get_posts','exclude_cat');
function exclude_cat( $query ) {
        if ( get_the_ID() == '113' ) {
		$tax_query = $query->get( 'tax_query' ) ?: array();
		$tax_query[] = array(
			'taxonomy' => 'st_category',
			'field'    => 'id',
			'terms'    => array( 115 ),
			'operator' => 'NOT IN',
		);
		$query->set( 'tax_query', $tax_query );
	}
	return $query;
}

    Thanks again 😀
