Question

我创建了名为＆＃39; product＆＃39;的高级内容类型POD。 POD具有关系文件字段，用于将图像上传到图库：字段名称为＆＃34; gallery＆＃34;。产品在同一产品中相互关联。荚。我想在前端显示相关领域的图像。到目前为止，通过将以下代码放入PODS模板，我没有运气：

<?php$related = $obj->field( 'related_products' );
if ( ! empty( $related ) && is_array($related) ) {
foreach ( $related as $rel ) {
$id = $rel[ 'id' ];
$name = $rel[ 'name' ];
$permalink = $rel[ 'permalink' ];
$photos=$rel['gallery'];
if ( ! empty( $photos ) && is_array($photos) ) {
        foreach ( $photos as $photo ) {
            echo wp_get_attachment_image($photo['ID'], 'thumbnail');                
        } //end of foreach
        }; //endif ! empty ( $photos )
echo '<a href="'.site_url( trailingslashit( 'products' ) . $rel[ 'permalink' ] ).'"><h4>' .$name.'</h4></a>';
} //end of foreach
} //endif ! empty ( $related )
?>

如果有人需要类似的东西，这就是我最终的目标：

<?php
$related = $obj->field( 'related_products' );
$photos = $obj->field('related_products.gallery' );
if ( ! empty( $related ) && is_array($related) ) {
foreach ( $related as $rel ) {
$id = $rel[ 'id' ];
$name = $rel[ 'name' ];
$permalink = $rel[ 'permalink' ];
if ( ! empty( $photos ) && is_array($photos) ) {
foreach ( $photos as $photo ) {
echo wp_get_attachment_image($photo['ID'], 'thumbnail');
break;
} //end of foreach
}; //endif ! empty ( $photos )
echo '<a href="'.site_url( trailingslashit( 'products' ) . $rel[ 'permalink' ] ).'"><h4>' .$name.'</h4></a>';
} //end of foreach
} //endif ! empty ( $related )
?>

我想只从图库中显示一个图像，这就是foreach循环中断的原因。要使所有附加图像删除此行。
