Question

我正在使用下面的代码显示空的子类别，其中没有任何帖子，我想隐藏这些。如果可能，请告诉我，如果是，那么

<?php
    $term = get_queried_object();
    $term_id = $term->term_id;
    $taxonomy_name = $term->taxonomy;

    $termchildren = get_term_children( $term_id, $taxonomy_name );

    echo '<ul>';
    foreach ( $termchildren as $child ) {
        $term = get_term_by( 'id', $child, $taxonomy_name );
        echo '<li><a href="' . get_term_link( $term, $taxonomy_name ) . '">' . $term->name.' ('. $term->count. ')</a></li>';
    }
    echo '</ul>';
?>

提前多多感谢

Answer 1

您可以使用$term->count检查是否有任何帖子。

foreach ( $termchildren as $child ) {
    $term = get_term_by( 'id', $child, $taxonomy_name );
    if($term->count > 0){
       echo '<li><a href="' . get_term_link( $term, $taxonomy_name ) . '">' . $term->name.' ('. $term->count. ')</a></li>';
    }
}

Answer 2

我还有其他解决方案

$termchildren = get_terms( $taxonomy_name, array( 'hide_empty' => true, 'parent' => $term_id ) );

Answer 3

您可以使用术语计数来检查空类别

if ( v == CLOCKWISE ) {
        if (random == 1) {
            new CountDownTimer(100,1) {
                @Override
                public void onTick(long millisUntilFinished) {
                    CLOCKWISE.setBackgroundColor(Color.GREEN);
                }
                @Override
                public void onFinish() {
                    CLOCKWISE.setBackgroundColor(Color.GRAY);
                    Animation clockwise = AnimationUtils.loadAnimation(NegativeActivity.this,R.anim.button_rotate_clockwise);
                    clockwise.setDuration(5000);
                    CIRCLE.startAnimation(clockwise);
                    Random r = new Random();
                    random = r.nextInt(11 - 1) + 1;
                    if(random == 1) {
                        textQueston.setText("Rotate the Circle Clockwise");
                    }
