显示不同的数组元素

Question

我有对象的数组：

Array 
(
    [0] => stdClass Object 
     (
      [id] => 24 
      [ban_id] => 163 
      [ban_url] => http://www.website.com/wp-content/uploads/2014/04/72890.jpg 
     ) 

    [1] => stdClass Object 
     (
      [id] => 25 
      [ban_id] => 162 
      [ban_url] => http://www.website.com/wp-content/uploads/2014/04/46860.jpg 
     ) 

    [2] => stdClass Object 
     (
      [id] => 26 
      [ban_id] => 169 
      [ban_url] => http://www.website.com/wp-content/uploads/2014/04/46871.jpg 
     ) 

) 

我也有一个WordPress循环：

$count = 0; 
while (have_posts()) : the_post(); 
    $count++; 
    $show_ad = $count%3 == 0; 
    if ($show_ad): 
     echo '<img src="..." alt="" />'; 
    endif; 
endwhile; 

我想显示一个（或甚至更多，取决于如果$ show_ad等于true（在这种情况下，每3个帖子），这些图像就会被用户选择）。

例如，1幅不同的图像，每3个帖子：

[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 0] 
[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 1] 
[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 2] 
[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 0] 
... 

或者另一实例中，2个不同的图像，每3个帖子：

[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 0] 
    [Image 1] 
[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 2] 
    [Image 0] 
[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 1] 
    [Image 2] 
[Wordpress POST 1] 
[Wordpress POST 2] 
[Wordpress POST 3] 
    [Image 0] 
    [Image 1] 
... 

任何帮助将不胜感激。

在回顾您的回复后，我相信回答您的问题的最佳方式是为您的横幅广告也创建一个增量变量。

查看对while循环的以下更改。

$count = 0; 
$banner_count = 0; 
while (have_posts()) : the_post(); 
    $count++; 
    $show_ad = $count%3 == 0; 
    if ($show_ad): 
     //I dont know the name of the banner object so i gave it $banner_object 
     $banner_url = $banner_object[$banner_count]->ban_url; 
     echo '<img src="' .$banner_url .'" alt="" />'; 

     //Increment Banner 
     $banner_count++; 

    endif; 

希望有帮助！让我知道你是否在寻找别的东西。如果您只有一定数量的横幅，那么您可能需要在横幅广告对象结束时重置banner_count。请参阅下面的代码

$count = 0; 
$banner_count = 0; 
while (have_posts()) : the_post(); 
    $count++; 
    $show_ad = $count%3 == 0; 
    if ($show_ad): 

     $banner_url = $banner_object[$banner_count]->ban_url; 
     echo '<img src="' .$banner_url .'" alt="" />'; 

     //Increment Banner 
     $banner_count++; 

     //If reached the end of the banner count 
     if($banner_count > count($banner_object)) { $banner_count = 0; } 

    endif;
