如何在“ foreach”中添加“ else”？

Question

我不知道如何添加else到foreach！

这是我的代码：

<?php $terms = get_the_terms( $post->ID , 'actor' ); 
    foreach ( $terms as $term ) {
        $term_link = get_term_link( $term, 'actor' );
        if( is_wp_error( $term_link ) )
        continue;
        echo '<a href="' . $term_link . '">' . $term->name . '</a>';
    }
?>

您可以尝试类似的方法：

<?php 
    $terms = get_the_terms( $post->ID , 'actor' ); 
    if ($terms) {
        foreach ( $terms as $term ) {
            $term_link = get_term_link( $term, 'actor' );
            if ( is_wp_error( $term_link ) )
                continue;
            echo '<a href="' . $term_link . '">' . $term->name . '</a>';
        }   
    } else {
        // do the work for else
    }
?>
