ACF Gallery分页在Worpdress [英] ACF Gallery Pagination in Worpdress

问题描述

这是我使用ACF Gallery字段类型创建画廊的方式.我成功显示了所有图像，但是我只想每页显示4张图像.我有一个如何对帖子类型进行分页的想法，但对如何对ACF画廊进行分页却一无所知.谢谢！

This is how I created my gallery using ACF Gallery field type. I successfully displayed all of the images, But I only want to display 4 images per page. I have an idea how to paginate a post type but I have no idea on how to paginate ACF gallery. Thanks!

<?php 

$images = get_field('field_59f2a1869ef2b');
$size = 'full'; 

if( $images ): ?>

        <?php foreach( $images as $image ): ?>

                <?php echo wp_get_attachment_image( $image['ID'], $size ); ?>

        <?php endforeach; ?>

<?php endif; ?> 

推荐答案

感谢您提供示例代码和示例链接.我终于做到了.这是代码.

Thank you for the sample codes and sample links. I finally did it. Here's the code.

<?php
$gallery = get_field('field_59f2a1869ef2b');
$images = array();


$items_per_page = 4;
$total_items = count($gallery);
$size = 'full'; 
$total_pages = ceil($total_items / $items_per_page);

if(get_query_var('paged')){
    $current_page = get_query_var('paged');
}
elseif (get_query_var('page')) {
    $current_page = get_query_var('page');
}
else{
    $current_page = 1;
}
$starting_point = (($current_page-1)*$items_per_page);

if($gallery){
    $images = array_slice($gallery,$starting_point,$items_per_page);
}

if(!empty($images)){
      foreach( $images as $image ):
            echo wp_get_attachment_image( $image['ID'], $size ); 
       endforeach;
}


$big = 999999999;
echo paginate_links(array(
    'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
    'format' => '?paged=%#%',
    'current' => $current_page,
    'total' => $total_pages,
    'before_page_number' => '<span class="screen-reader-text">'.$translated.' </span>'
));


?>
