Vérifiez si la catégorie actuelle a des enfants

Il y apeut-être unemeilleurefaçon de lefaire ounon,mais voici commentje procéderais:

 $term = get_queried_object();

$children = get_terms( $term->taxonomy, array(
'parent'    => $term->term_id,
'hide_empty' => false
) );
// print_r($children); // uncomment to examine for debugging
if($children) { // get_terms will return false if tax does not exist or term wasn't found.
    // term has children
}
 

Si leterme detaxonomie actuel a desenfants,lafonction get_terms renverra untableau,sinonelle renverra false.

There may or may not be a better way to do this, but here's how I would do it:

$term = get_queried_object();

$children = get_terms( $term->taxonomy, array(
'parent'    => $term->term_id,
'hide_empty' => false
) );
// print_r($children); // uncomment to examine for debugging
if($children) { // get_terms will return false if tax does not exist or term wasn't found.
    // term has children
}

If current taxonomy term has children the get_terms function will return an array, otherwise it will return false.

Tested and works on my local vanilla install with Custom Post Type UI plugin used for CPT generation.

Ilexiste également unepossibilité WPgénérique de lefaire via get_term_children .

 <?php
$children = get_term_children($termId, $taxonomyName);

if( empty( $children ) ) {
    //do something here
}
 

There's also a generic WP possibility to do this via get_term_children.

<?php
$children = get_term_children($termId, $taxonomyName);

if( empty( $children ) ) {
    //do something here
}

En supposant que vousessayez defiltrer vostermespour afficher uniquement lestermes qui ont desenfants ounon,vouspouvezen fait utiliser leparamètre childless dans votrefonction get_terms().

 $children = get_terms( 
    'taxonomy' => '$taxonomy_slug',
    'hide_empty' => false,
    'childless' => true
  ) 
);
 

Cela affichera untableau determes quin'ontpas d'enfants.

Assuming that you are trying to filter your terms to only show terms that either have children or not, you can actually use the childless parameter in your get_terms() function.

$children = get_terms( 
    'taxonomy' => '$taxonomy_slug',
    'hide_empty' => false,
    'childless' => true
  ) 
);

This will output an array of terms that don't have children.
