如何创建具有多个循环的多维数组

时间：2013-03-31 作者：INT

我有一个循环，在这里我循环遍历我的CPT的每个帖子，获取每个帖子的标题和内容，并将其放入一个数组中。这没问题。

但碰巧我创建了一个可重复的字段Advanced Custom Fields 这些职位都有。这些字段包含我要添加到数组中的图像和标题。

这是我当前的代码

$args = array(
    \'posts_per_page\' => \'-1\',
    \'post_type\' => \'work\',
    \'orderby\' => \'ID\',
    \'order\' => \'DESC\',
);

$data = array(\'work\' => array());

$loop = new WP_Query($args);
if( $loop->have_posts() ):
    while( $loop->have_posts() ): $loop->the_post();
        $id = $loop->post->ID;
        $data[\'work\'][$id] = array(
            \'title\' => apply_filters( \'the_title\', $loop->post->post_title ),
            \'content\' => apply_filters( \'the_content\', $loop->post->post_content ),             
        );
    endwhile;
endif;
wp_reset_postdata();
哪些输出

{
    "work":{
        "45":{
            "title":"Project 7",
            "content":"<p>I am the other text.<\\/p>\\n"
        },
    }
}
我想要的是这样的

{
    "work":{
        "45":{
            "title":"Project 7",
            "content":"<p>I am the other text.<\\/p>\\n"
            "items":{
                "1":{
                    "caption":"I\'m an image",
                    "url":"www"
                },
                "2":{
                    "caption":"I\'m another image",
                    "url":"www"
                },
            }
        },
}
获取不同附件的循环如下所示。。

<?php if(get_field(\'work\')): ?>
<?php while(has_sub_field(\'work\')):
    $attachment_id = get_sub_field(\'image\');
    $caption = the_sub_field(\'caption\');
    $image = wp_get_attachment_image_src( $attachment_id, work );    
endwhile; ?>     
<?php endif; ?>
。。但我无法理解如何将这个循环的结果放入数组中。如果有人能给我指出正确的方向，我会很高兴的！谢谢

我认为这不是一个限制性的Wordpress问题，但你可以试试

$args = array(
    \'posts_per_page\' => \'-1\',
    \'post_type\' => \'work\',
    \'orderby\' => \'ID\',
    \'order\' => \'DESC\',
);

$data = array(\'work\' => array());

$loop = new WP_Query($args);
if( $loop->have_posts() ):
    while( $loop->have_posts() ): $loop->the_post();
        $id = $loop->post->ID;

        $attachments=array();
        if(get_field(\'work\')): 
           while(has_sub_field(\'work\')):
              $attachment_id = get_sub_field(\'image\');
              $caption = the_sub_field(\'caption\');
              $image = wp_get_attachment_image_src( $attachment_id, \'work\' );   
              $attachments[$attachment_id]=array("caption"=>$caption,"url"=>$image); 
           endwhile;    
        endif; 

        $data[\'work\'][$id] = array(
            \'title\' => apply_filters( \'the_title\', $loop->post->post_title ),
            \'content\' => apply_filters( \'the_content\', $loop->post->post_content ),           
            \'items\'  => $attachments;  
        );
    endwhile;
endif;
wp_reset_postdata();

function get_acf_field( $post_id ) {

  if( get_field( \'work\', $post_id ) ) {

      $attachment_id = get_sub_field(\'image\');
      $caption = the_sub_field(\'caption\');
      $image = wp_get_attachment_image_src( $attachment_id, work );

      $result[] = array( \'caption\' => $caption, \'url\' => $image );

    }
  }

  return $result;

}
我希望这有帮助。
