从WordPress对象检索post_title

Question

我正在尝试从WordPress对象检索文章标题。

    <?php
        $args = array(
            'post_type' => 'cases',
            'posts_per_page' => -1,
        );
        $the_query = new WP_Query( $args );
        if ( $the_query->have_posts() ):
            while ( $the_query->have_posts() ): $the_query->the_post();
                $case_title = get_field('post_title');
                echo $case_title;

                var_dump($the_query);
    ?>

    <?php endwhile; wp_reset_postdata(); endif;?>

我应该做什么来检索标题？

Answer 1

要回显标题，可以执行以下操作<？php the_title()；？>并且要将标题放入var中，可以执行以下操作:$title=get_the_title()；

        );
        $the_query = new WP_Query( $args );
        if ( $the_query->have_posts() ):
            while ( $the_query->have_posts() ): $the_query->the_post();
                $case_title = get_the_title();
                echo $case_title;
                // or
                echo the_title();

                var_dump($the_query);
    ?>

    <?php endwhile; wp_reset_postdata(); endif;?>
