使用特定的In-Post选项选择帖子的PHP循环

我正在尝试构建一个特色帖子滑块，以显示我所看到的任何帖子mark as a "featured" （使用in-post选项）无论类别或标记类型。。。我是wordpress的新手，虽然我懂一点php语言，但我不是一个程序员：(

滑块已在工作。问题是，如何构建带有循环的滑块来显示最后一个7 贴子标记为“特色”，并带有相应的特色图片？

我已经在post edit页面的metabox中设置了in-post选项，并且在我的函数中配置了图像大小。php。。。

我在genesis框架中使用wordpress 3.1。

这是滑块代码

<div class="slider">
    <ul class="main-wapper">
      <li> <img src="path to featured img" title="the post title" height="300" width="315">
        <div class="main-item-desc">
          <h2><a target="_parent" title="Post Title" href="post link">POST TITLE</a></h2>
          <p>Post Description limited to 150 character</p>
        </div>
      </li>
      <li> <img src="path to featured img" title="the post title" height="300" width="315">
        <div class="main-item-desc">
          <h2><a target="_parent" title="Post Title" href="post link">POST TITLE</a></h2>
          <p>Post Description limited to 150 character</p>

          <p>Post Description limited to 150 character</p>
        </div>
      </li>
      </ul>
  </div>
  <div class="navigator-outer">
    <ul class="navigator">

Increase offset while looping

我正在编写一个自定义帖子插件，它将自定义帖子分组显示为选项卡。每组4个岗位。是否可以编写一个偏移量随每次循环而增加的查询？因此，结果将是：-第一个查询显示从1到4的帖子-第二个查询显示从5到8的帖子-第三个查询显示从9到12的帖子等。 <div class=\"official-matters-tabs\"> <?php $args = array(\'post_type\' => \'official-matters\', \'showp

当in_the_loop()为假时，何时以及为什么is_Single(‘my_cpt’)为真？

我正在使用模板系统的示例代码。此地址的页码：http://project.test/my_cpt/hello-post/.无法理解原因is_singular( \'my_cpt\' ) 是true 虽然in_the_loop() 是false.在页面模板中The Loop "E；“工程”：if ( have_posts() ) { while ( have_posts() ) { the_post(); ?>
