Excluding certain categories from the search function

[Madeleine Parkyn]

Hello
Is it possible to exclude certain categories from being returned in the search function?

Also, is it possible to prevent certain categories from showing in the category dropdown for the search funtion.

I’ve tried listing them by slug, but those not listed are appearing in the drop-down.

[event_search event_start_after=”now” posts_per_page=”8″ event-category=”music,adult-outreach,education,exhibition,featured,family,other-events,special-services” filters=”date,event_category”]

Here is the page: http://minster.southwellminster.org/event-search/

Many thanks for your help, I’m finding it a very useful plugin.
Best wishes
Madeleine

Hi
I’d really appreciate some guidance with the query above about excluding certain categories from the displayed search results.

Many thanks

Hi Madeleine,

There isn’t an option to do this, so you would have to modify the code base directly. In line of 203 of includes/shortcodes.php, there is:

$tax = get_taxonomy( 'event-venue' );
$venue_objs = eo_get_venues();
if ( $venue_objs ) {
   ...

You can modify the $venue_objs objecto filter out any venues you don’t want:

$tax = get_taxonomy( 'event-venue' );
$venue_objs = eo_get_venues();
$venue_objs = array_filter($venue_objs, function($venue) {
    $whitelist = array('music', 'adult-outreach', 'education');
    return in_array($venue->slug, $whitelist);
});
if ( $venue_objs ) {
   ...

Many thanks Stephen. I’ll give it a go.

Hi Stephen

I’m a bit confused. I asked about catgories, but your reply refers to venues, with category slugs?

Many thanks
Madeleine

Sorry, for categories line 321 has

$taxonomy = get_taxonomy( $filter );
$term_objs = get_terms( $taxonomy->name, array( 'hide_empty' => 0 ) );

You can modify that to:

$taxonomy = get_taxonomy( $filter );
$term_objs = get_terms( $taxonomy->name, array( 'hide_empty' => 0 ) );
if('event-category' === $filter){
    $term_objs = array_filter($term_objs, function($term) {
       $whitelist = array('music', 'adult-outreach', 'education');
       return in_array($term->slug, $whitelist);
    });
}

Hi Stephen
I’m not seeing that at line 321 of includes/shortcodes.php.

From line 203 I’m seeing

    $tax = get_taxonomy( 'event-category' );
                $cat_objs = get_terms( 'event-category', array( 'hide_empty' => 0 ) );
                if ( $cat_objs ) {
                    $cats = array_combine( wp_list_pluck( $cat_objs, 'slug' ), wp_list_pluck( $cat_objs, 'name' ) );
                } else {
                    $cats = array();

What should I be changing?

Many thanks for your help

Hi Stephen

I was wondering if you’d had any further thoughts about this?

Many thanks
Madeleine

In that case, please try:

case 'event_category':
    $tax = get_taxonomy( 'event-category' );
    $cat_objs = get_terms( 'event-category', array( 'hide_empty' => 0 ) );
    $cat_objs = array_filter($cat_objs, function($cat) {
       $whitelist = array('music', 'adult-outreach', 'education');
       return in_array($cat->slug, $whitelist);
    });
    if ( $cat_objs ) {
        $cats = array_combine( wp_list_pluck( $cat_objs, 'slug' ), wp_list_pluck( $cat_objs, 'name' ) );
    } else {
        $cats = array();
    }

(note the added four lines).

    $cat_objs = array_filter($cat_objs, function($cat) {
       $whitelist = array('music', 'adult-outreach', 'education');
       return in_array($cat->slug, $whitelist);
    });

Thanks very much Stephen. That has done the trick, now I can choose which categories display on the drop down.

Thank you for your help. Have a good weekend.

Hi Stephen,

I have tried adding this custom code which you suggested back in 2018 to exclude certain categories from the search function but this doesn’t seem to be working for me.

Is there a chance that this needs to be updated?

All the best,
George

I think it has changed slightly. Line 321 of includes/shortcodes.php is currently:

$term_objs = get_terms( $taxonomy->name, array( 'hide_empty' => 0 ) );
if ( $term_objs && ! is_wp_error( $term_objs ) ) {
    $terms = array_combine( wp_list_pluck( $term_objs, 'slug' ), wp_list_pluck( $term_objs, 'name' ) );
} else {
    $terms = array();
}

if you modify it so it reads:

$term_objs = get_terms( $taxonomy->name, array( 'hide_empty' => 0 ) );
if ( $taxonomy->name == 'event-category') {
    $term_objs = array_filter($term_objs, function($term) {
        $whitelist = array('music', 'adult-outreach', 'education');
        return in_array($term->slug, $whitelist);
     });
}
if ( $term_objs && ! is_wp_error( $term_objs ) ) {
    $terms = array_combine( wp_list_pluck( $term_objs, 'slug' ), wp_list_pluck( $term_objs, 'name' ) );
} else {
    $terms = array();
}

(i.e. the following has been added after the first line shown)

if ( $taxonomy->name == 'event-category') {
    $term_objs = array_filter($term_objs, function($term) {
        $whitelist = array('music', 'adult-outreach', 'education');
        return in_array($term->slug, $whitelist);
     });
}
