我检查过类别'categoryone'是否有父类别,Yes categoryone是否有一个名为categorydad的父类别,知道我想检查categorydad是否有父类...
$tid = term_exists('categoryone', 'category', 0);
$term_ids = array();
if ( $tid !== 0 && $tid !== null )
{
$term_ids[] = $tid['term_id'];
}
else
{
// Finns inte!
$insert_term_id = wp_insert_term( 'categoryone', 'category' );
// var_dump( $insert_term_id );
if ( ! is_wp_error )
$term_ids[] = $insert_term_id;
}
wp_set_post_categories( $insert_id, $term_ids );
答案 0 :(得分:1)
function category_has_parent($catid){
$category = get_category($catid);
if ($category->category_parent > 0){
return true;
}
return false;
}
if (category_has_parent('22')){
//true there is a parent category
}else{
//false this category has no parent
}
要检查相反的方式(如果某个类别有子项),您可以使用get_categories
$children = get_categories(array('child_of' => id,'hide_empty' => 0));
if (count($children) > 1){
//has childern
}else{
//no children
}
