WordPress ACF 复选框循环

Question

我目前的 CPT 为 'restaurant'。每个餐厅可以有多个 'features'，由用户在后端通过 ACF 复选框字段选择。

我希望能够遍历此字段并为选中的每个复选框应用 class 名称。

在下面的示例中，餐厅勾选了 4 个可能字段中的 3 个。但是，只有 'Parking' 图标显示（4 次）- 可能是由于我的 if 语句。

理想情况下，我希望它循环遍历每个 'if'，获取附加到 $feature_icon 的字符串，然后在范围下方的 echo 中将其吐出。

我试过将 if 语句的部分移动到 'foreach' 循环中，但无济于事。

如有任何建议，谢谢。

<?php if( $featured_restaurants ): ?>
<?php foreach ( $featured_restaurants as $featured_restaurant ): ?>

<div class="card__inputs"> <!-- Featured card specific icons start -->

<?php
    if(in_array('alcohol', $restaurant_features)):
        $feature_icon = "Alcohol";
    endif;

    if(in_array('family_friendly', $restaurant_features)):
        $feature_icon = "Family-Friendly";
    endif;

    if(in_array('open_late', $restaurant_features)):
        $feature_icon = "Open-Late";
    endif;

    if(in_array('parking', $restaurant_features)):
        $feature_icon = "Parking";
    endif;
?>

    <div class="details u-float-left"> <!-- Featured card specific icons container start -->
    <span class="icon icon--medium icon--Italian"></span>
    <?php if($restaurant_features): ?>
        <?php foreach($restaurant_features as $restaurant_feature): ?>
            <span class="icon icon--medium icon--<?php echo $feature_icon; ?>"></span>
        <?php endforeach; ?>
    <?php endif; ?>

    </div> <!-- Featured card specific icons container end -->

    </div> <!-- Featured card specific icons end -->

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

使用数组。

<?php if( $featured_restaurants ): ?>
<?php foreach ( $featured_restaurants as $featured_restaurant ): ?>

<div class="card__inputs"> <!-- Featured card specific icons start -->

<?php
    if(in_array('alcohol', $restaurant_features)):
        $feature_icon['alcohol'] = "Alcohol";
    endif;

    if(in_array('family_friendly', $restaurant_features)):
        $feature_icon['family_friendly'] = "Family-Friendly";
    endif;

    if(in_array('open_late', $restaurant_features)):
        $feature_icon['open_late'] = "Open-Late";
    endif;

    if(in_array('parking', $restaurant_features)):
        $feature_icon['parking'] = "Parking";
    endif;
?>

    <div class="details u-float-left"> <!-- Featured card specific icons container start -->
    <span class="icon icon--medium icon--Italian"></span>
    <?php if($restaurant_features): ?>
        <?php foreach($restaurant_features as $restaurant_feature): ?>
            <span class="icon icon--medium icon--<?php echo $feature_icon[$restaurant_feature]; ?>"></span>
        <?php endforeach; ?>
    <?php endif; ?>

    </div> <!-- Featured card specific icons container end -->

    </div> <!-- Featured card specific icons end -->

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

<div class="card__inputs"> <!-- Featured card specific icons start -->
    <?php
    $feature_icon = [
        'alcohol' => "Alcohol",
        'family_friendly' => "Family-Friendly",
        'open_late' => "Open-Late",
        'parking' => "Parking",
    ];
    ?>
    <div class="details u-float-left"> <!-- Featured card specific icons container start -->
    <span class="icon icon--medium icon--Italian"></span>
    <?php if($restaurant_features): ?>
        <?php foreach($restaurant_features as $restaurant_feature): ?>
            <span class="icon icon--medium icon--<?php echo $feature_icon[$restaurant_feature]; ?>"></span>
        <?php endforeach; ?>
    <?php endif; ?>

    </div> <!-- Featured card specific icons container end -->

    </div> <!-- Featured card specific icons end -->

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

或者删除 if 语句并使用 str_replace()

<?php if( $featured_restaurants ): ?>
<?php foreach ( $featured_restaurants as $featured_restaurant ): ?>

<div class="card__inputs"> <!-- Featured card specific icons start -->
    <div class="details u-float-left"> <!-- Featured card specific icons container start -->
    <span class="icon icon--medium icon--Italian"></span>
    <?php if($restaurant_features): ?>
        <?php foreach($restaurant_features as $restaurant_feature): ?>
        <?php $icon = str_replace(' ', '-', ucwords(str_replace('_', ' ', $restaurant_feature))); ?>
            <span class="icon icon--medium icon--<?php echo $icon ; ?>"></span>
        <?php endforeach; ?>
    <?php endif; ?>

    </div> <!-- Featured card specific icons container end -->

    </div> <!-- Featured card specific icons end -->

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