我正在尝试获取post_title。这是我目前所拥有的：

    <?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;?>

但它没有检索标题。

我应该怎么做才能检索标题？

【解决方案1】：

要回显标题，您可以这样做 <?php the_title(); ?> 并将标题放在 var 中，您可以这样做 $title = get_the_title();

<?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_the_title();
                echo $case_title;
                // or
                echo the_title();

                var_dump($the_query);
    ?>

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

感谢您的回答，但这是获取标题的标准 wordpress 方式。该对象派生自自定义帖子类型。例如，我正在尝试提取 post_title。
我想也许你把它们弄混了。如果它是自定义帖子类型 get_field() 应该可以工作。你可以试试echo the_field();。
@mdarmanin get_the_title() 应检索 CPT 帖子标题，如 var_dump 中所示。请参阅第一个帖子对象的摘录：[0]=> object(WP_Post)#4270 (24) { ["ID"]=> int(19269) ["post_author"]=> string(1) "2" ["post_date "]=> 字符串(19) "2018-10-02 10:46:05" ["post_date_gmt"]=> 字符串(19) "2018-10-02 08:46:05" ["post_content"]=> string(0) "" ["post_title"]=> string(17) "Terberg - ANNAbel" ["post_status"]=> string(7) "publish" ["post_name"]=> string(7) "annabel" ["guid"]=> string(48) "zeo.nl/?post_type=cases&p=19269" ["post_type"]=> string(5) "cases" }
有没有什么快速的方法可以像在 JS 中那样以更有序的方式对这样的对象进行排序？
好吧，没关系，做一个 var_dump 并有序地检查 DOM 显示
