仅按get_field值的第一个字母查询和显示

我找不到我的问题的答案，只希望你能找到相关的答案。

我在一家杂志网站上工作，我需要按姓氏在列表中显示贡献者的姓名。贡献者是由自定义分类法创建的。其中一些名字more than one First names.

实例

简·加布里埃拉·玛丽亚Sanchez<约翰Smith

因此，我所做的是为姓氏创建了一个自定义字段。它起作用了，并将它们按正确的顺序排列。这是我在一些资源的帮助下创建的代码here. 现在我唯一想做的就是只通过get\\u字段的第一个字母（\'family\\u name\'，$term）进行查询。能够在我的页面上对它们进行分组。A、 B、C、D。。。。。

            <?php 

            $terms = get_terms(\'contributors\');

            $args = array(\'contributors\' => $term->slug);
            $query = new WP_Query( $args );


            $order_terms = array();
            foreach( $terms as $term ) {
            $position = get_field(\'family_name\', $term);
            $order_terms[$position] =\'<li><a href="\'. get_bloginfo( \'url\' ) . \'/contributors/\' . $term->slug . \'">\'.$term->name.\'</a></li>\';
            }

            ksort($order_terms);

            foreach( $order_terms as $order_term ) {
            echo $order_term;
            }

            ?>

也许这不可能，让我知道。

提前谢谢。

<?php $terms = get_terms(array( \'taxonomy\' => \'contributors\', \'meta_key\' => \'letter_group\', \'meta_value\' => \'a\' )); if(!empty ($terms)) { $args = array( \'contributors\' => $term->slug, ); $query = new WP_Query( $args ); ?> <section class="names"> <h3>A</h3> <p> <?php $order_terms = array(); foreach( $terms as $term ) { $position = get_field(\'family_name\', $term); $order_terms[$position][] =\'<a href="\'. get_bloginfo( \'url\' ) . \'/contributors/\' . $term->slug . \'">\'.$term->name.\'</a><br>\'; } ksort($order_terms); foreach( $order_terms as $a ) { foreach($a as $order_term) echo $order_term;} wp_reset_postdata(); ?> </p> </section> <?php } ?>

// Your previous code. // Say this is your $oder_terms variable $order_terms = array( \'Sanchez\' => \'Sanchez Link\', \'Smith\' => \'Smith Link\', \'Dramatist\' => \'Dramatist Link\', \'Rashed\' => \'Rashed Link\', \'Munez\' => \'Munez Link\', \'James\' => \'James Link\', \'Jacky\' => \'Jacky Link\', ); ksort($order_terms); // After ksort($order_terms); we get below array /* Array ( [Dramatist] => Dramatist Link [Jacky] => Jacky Link [James] => James Link [Munez] => Munez Link [Rashed] => Rashed Link [Sanchez] => Sanchez Link [Smith] => Smith Link ) */ // Now we need to group them on the basis of alphabet. Right ? $new_order_terms = array(); foreach($order_terms as $key => $value) { $firstLetter = substr($value, 0, 1); $new_order_terms[$firstLetter][$key] = $value; } // Now if you do print_r($new_order_terms); your output will be /* Array ( [D] => Array ( [Dramatist] => Dramatist Link ) [J] => Array ( [Jacky] => Jacky Link [James] => James Link ) [M] => Array ( [Munez] => Munez Link ) [R] => Array ( [Rashed] => Rashed Link ) [S] => Array ( [Sanchez] => Sanchez Link [Smith] => Smith Link ) ) */ // All grouped by their first letter.
