在带有 ACF 的 foreach 循环中使用 if 语句

Question

我在处理一些 PHP 和 ACF 时遇到了问题。我对 PHP 很陌生，但结构如下。我有一个类别的 ACF Select 字段，其中包括管理员、销售员和文员。例如，我正在尝试为每个类别下的每个人呈现卡片

管理员

人1人3人5

销售人员

人 2 人 6

文员

第 7 个人

这是我的代码：

$members_query = new WP_Query( array(
    'post_type' => 'team-member',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'orderby' => 'menu_order',
    'order' => 'asc'
) );


// abort if no members to show
if ( ! $members_query->have_posts() ) return;

// split members into two columns 
$members_all = $members_query->posts;
$members_list = array();
foreach ($members_query->posts as $loop_index => $member_post ) {
    $members_list[] = $member_post;
}

// use a fn to output member cards for each column 
if ( ! function_exists( 'opt_render_team_member' ) ) {
    function opt_render_team_member( $member_post, $id_prefix = '' ) {

        $name = $member_post->post_title;
        $image = get_field( 'image', $member_post->ID );
        $job_title = get_field( 'job_title', $member_post->ID );
        $bio = get_field( 'bio', $member_post->ID );
        $certifications = get_field( 'certifications', $member_post->ID );
        $category = get_field ( 'category', $member_post->ID);
        ?>

        <div class="mb-7">

            <?php if ( $image ) : ?>
                <div class="team-members__headshot">
                    <?= wp_get_attachment_image( $image['ID'], 'medium_large' ); ?>
                </div>
            <?php endif; ?>

            <?php if ( $name ) : ?>
                <h2 class="team-members__name">
                    <?= $name; ?>
                </h2>
            <?php endif; ?>

            <?php if ( $job_title ) : ?>
                <h3 class="team-members__position">
                    <?= $job_title; ?>
                </h3>
            <?php endif; ?>

            <?php if ( $bio ) : ?>
                <?= $bio; ?>
            <?php endif; ?>

            <?php if ( ! empty( $certifications ) ) : ?>
                <button 
                    class="team-members__credentials-toggle" 
                    type="button" 
                    data-toggle="collapse" 
                    data-target="#team-member-<?= $id_prefix; ?>" 
                    aria-expanded="false" 
                    aria-controls="team-member-<?= $id_prefix; ?>"
                >
                    <?= __( 'See their credentials', 'optimize' ); ?>
                </button>
                <ul class="team-members__credentials collapse" id="team-member-<?= $id_prefix; ?>">
                    <?php foreach ( $certifications as $certification ) : ?>
                        <li>
                            <?= $certification['certification']; ?>
                        </li>
                    <?php endforeach; ?>
                </ul>
            <?php endif; ?>

        </div>
        
        <?php
    }
}

?>

<div class="team-members alignfull">
    <div class="container">

        <div class="row d-none d-lg-flex">

        <?php foreach ( $members_list as $loop_index => $member_post ) : ?>
            <?php if(get_field( 'category' ) == "admin") : ?>
                <div class="col-12 col-md-6 col-lg-4">
                    <?php opt_render_team_member( $member_post, "$loop_index" ); ?>               
                </div>
            <?php endif; ?>
        </div>
    </div>
</div>

问题是当我添加 if(get_field('category') == "admin" 时它什么也没显示，但是如果我删除该 if 语句，我会看到所有成员，但看不到按照我的意愿排序。任何建议或想法。谢谢！
