比较 WordPress 循环中的 ACF 字段以查看它们是否相同

Comparing an ACF field within a WordPress loop to see if they are the same

我有一个正在提取 ACF 字段的 WordPress 循环。我需要确定字段名称是否相同,如果相同,我想将它们包装在 div 中。我已经创建了一个自定义索引页面,但我们希望能够为具有与下拉列表相同的作者姓名的字段设置样式。所以我需要以某种方式比较它们是否相同。

这是我正在处理的网站http://test.improveyourenglish.com/library/ 因此,例如,我想将 "Jane Austin" 包装在 div 中,以便我可以将其设置为下拉列表。

非常感谢任何帮助,我们将不胜感激。

这是我目前使用的代码

add_action('genesis_loop', 'book_archive_page');
function book_archive_page() {
echo '<div class="left-side">';
echo '<p>The following titles are sorted by author surnames.</p>';
?><div class="enter"><a href="#$term->name"><?php echo $term->name; ?>
</div></a><?php
$post_type = 'book';

// Get all the taxonomies for this post type
$taxonomies = get_object_taxonomies( array( 'post_type' => $post_type ) 
);

foreach( $taxonomies as $taxonomy ) :

    // Gets every "category" (term) in this taxonomy to get the 
respective posts
    $terms = get_terms( $taxonomy );

    foreach( $terms as $term ) : ?>

        <section class="category-section">

        <div class="row">
        <div class="span12">
            <a name="<?php echo $term->name; ?>"><h2 style="padding-
   top: 300px; margin-top: -300px;"><?php echo $term->name; ?></h2>
 </a>




        </div>

        <?php
        $args = array(
                'post_type' => $post_type,
                'posts_per_page' => -1,  //show all posts
                'tax_query' => array(
                    array(
                        'taxonomy' => $taxonomy,
                        'field' => 'slug',
                        'terms' => $term->slug,
                    )
                )

            );
        $posts = new WP_Query($args);

        if( $posts->have_posts() ): while( $posts->have_posts() ) : 
  $posts->the_post(); ?>

            <div class="span4">

                <article class="inner-post clearfix">



                    <div class="inner-content">

                   <a href="<?php echo get_permalink(); ?>" title="Read <?php echo get_the_title(); ?>"><div class="author-archive-text"><?php the_field('author_full_name'); ?></div><div class="title-archive-book"><?php  echo get_the_title(); ?></div></a>


                    </div>
                </article>


            </div>

        <?php endwhile; endif; ?>
        </div>
        <hr>
        </section>

    <?php endforeach;

endforeach; ?>
<?php
 }
echo '</div>';

如果我理解你想要的是正确的,你需要做的是将 "current" 作者姓名记录在一个变量中,并在你的循环中使用它来将它与下一个作者姓名进行比较。如果是不同的作者,则结束前一个作者的包装器并为下一个作者启动一个新的包装器。

$current_author = "";    // variable to store the current author 

$posts = new WP_Query($args); ?>

<div class="author-wrapper"> <!-- start the wrapper div for the first author -->

<?php if( $posts->have_posts() ): while( $posts->have_posts() ) : $posts->the_post(); ?>

    <?php 
    // check if we have a new author
    if (the_field('author_full_name') != $current_author) {
        // update current_author var to make the new author the current one
        $current_author = the_field('author_full_name'); 
        // close the previous author's wrapper and start a new one
        ?>
        </div>
        <div class="author-wrapper">
    <?php } ?>

         <div class="span4">
            <article class="inner-post clearfix">
                <div class="inner-content">

               <a href="<?php echo get_permalink(); ?>" title="Read <?php echo get_the_title(); ?>"><div class="author-archive-text"><?php the_field('author_full_name'); ?></div><div class="title-archive-book"><?php  echo get_the_title(); ?></div></a>

                </div>
            </article>

        </div>
<?php endwhile; endif; ?>

</div> <!-- end the wrapper div for the last author -->
