Fronted Search Setting options [esclude terms empty]

[K15Lmk98]

This is an automatic translation

Good day,

Frontend Search Settings > Categories & Taxonomy Terms, i added the taxonomy “luoghi” with over 1000 terms. – see screenshot1 –

It is possible, perhaps through a filter to exclude all empty terms, and leave only those who post?

Thanks, Claudio_

Hi Claudio!

It is actually possible with a filter. Use this code for your case to filter the “luoghi” taxonomy:

[php]add_filter( ‘asp_fontend_get_taxonomy_terms’, ‘asp_filter_empty_terms’, 1, 3 );

function asp_filter_empty_terms($terms, $taxonomy, $args) {
if ( $taxonomy == ‘luoghi’ ) {
return get_terms($taxonomy, array(
‘orderby’ => $args[‘orderby’],
‘order’ => $args[‘order’],
‘taxonomy’=> $taxonomy,
‘hide_empty’ => 1
));
}
return $terms;
}[/php]

Hi Ernest,

Thanks for the filter.
I just wanted to take the term parent, and I modified the code with ‘parent’ => 0:

[code]add_filter( ‘asp_fontend_get_taxonomy_terms’, ‘asp_filter_empty_terms’, 1, 3 );
function asp_filter_empty_terms($terms, $taxonomy, $args) {
if ( $taxonomy == ‘luoghi’ ) {
return get_terms($taxonomy, array(
‘orderby’ => $args[‘orderby’],
‘order’ => $args[‘order’],
‘taxonomy’=> $taxonomy,
‘parent ‘ => 0,
‘hide_empty’ => 1
));
}
return $terms;
}[/code]

But strangely always returns the children – see screnshot –

You have a solution?

Thanks, Claudio_

Hi,

The parent =>0 parameter works on my test environment, it only displays parent elements, so I don’t know what is wrong.

If you want, you can provide temporary log-in and FTP and I can take a look.

Hi Ernest,

in fact it is really strange. I disabled some plugins that could interfere with ASP, but the result does not change.

I’m developing locally.
When I publish the site I send accesses.

Thanks, Claudio_

Hi Ernest,

This is a machine translation.

Like I said, it is strange that ‘parent’ => 0 does not work.

However I want to share the solution I found, if other users had my need.

[code]add_filter( ‘asp_fontend_get_taxonomy_terms’, ‘asp_filter_empty_terms’, 1, 3 );
function asp_filter_empty_terms($terms, $taxonomy, $args) {
if ( $taxonomy == ‘luoghi’ ) {
$terms = get_terms($taxonomy, array(
‘orderby’ => $args[‘orderby’],
‘order’ => $args[‘order’],
‘taxonomy’=> $taxonomy,
‘parent ‘ => 0,
‘hide_empty’ => 1
));
foreach ($terms as $key =>$singleTerm) :
$term = get_term_by(‘id’, $result->term_id, $taxonomy);
if ( $singleTerm->parent != 0 ) :
unset($terms[$key]);
endif;
endforeach;
return $terms;
}

return $terms;
}[/code]

Ticket chiuso. Thanks for the support, Claudio_
