Php wordpress显示所有帖子，而不是分类帖子

我试图在不同的页面上显示不同类别的帖子，这样我就可以在“服务”和“案例研究”页面上使用它们

我已经设置了两个页面，它们显示每个帖子的链接，但是显示的是所有帖子，而不仅仅是特定类别的帖子

我的代码在每一页上都是相同的，除了文章类别ID

如何在单独的页面上显示单独的类别

服务页面：

              <?php // PAGE LINK/TITLE


if (is_page()) {
  $cat=get_cat_ID($post->post_title); //use page title to get a category ID
  $posts = get_posts ("cat=$cat&showposts=4");
  if ($posts) {
    foreach ($posts as $post):
      setup_postdata($post); 

                  if ( has_post_thumbnail() ) { // PULLS IN IMAGE check if the post has a Post Thumbnail assigned to it.
    the_post_thumbnail();
} 


    ?>




      <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

      <?php //PULLS IN EXCERPT
$my_excerpt = get_the_excerpt();
if ( '' != $my_excerpt ) {
    // Some string manipulation performed
}
echo $my_excerpt; // Outputs the processed value to the page




?>
          <?php endforeach;
  }
}
?> 

案例研究页面：

        <?php // PAGE LINK/TITLE


if (is_page()) {
  $cat=get_cat_ID($post->post_title); //use page title to get a category ID
  $posts = get_posts ("cat=$cat&showposts=5");
  if ($posts) {
    foreach ($posts as $post):
      setup_postdata($post); 

                  if ( has_post_thumbnail() ) { // PULLS IN IMAGE check if the post has a Post Thumbnail assigned to it.
    the_post_thumbnail();
} 


    ?>




      <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

      <?php //PULLS IN EXCERPT
$my_excerpt = get_the_excerpt();
if ( '' != $my_excerpt ) {
    // Some string manipulation performed
}
echo $my_excerpt; // Outputs the processed value to the page




?>
          <?php endforeach;
  }
}
?>

没有特定的类别设置，只有要显示的帖子数量，在本例中为10

 <?php // PAGE LINK/TITLE


if (is_page()) {
  $cat=get_cat_ID($post->post_title); //use page title to get a category ID

  $posts = get_posts ("category_name=service&posts_per_page=10"); //CHANGE CODE AND ADD THIS LINE***************************

  if ($posts) {
    foreach ($posts as $post):
      setup_postdata($post); 

                  if ( has_post_thumbnail() ) { // PULLS IN IMAGE check if the post has a Post Thumbnail assigned to it.
    the_post_thumbnail();
} 


    ?>

停止滥用和向

$posts

global分配垃圾。另外，在更改itI后重置

$post

全局。我不知道PHP或wordpress，因此我如何更改上面的内容以显示特定的分类帖子？停止滥用并为

$posts

全局设置任何垃圾。另外，在更改itI后重置

$post

全局。我不知道PHP或wordpress，那么如何更改上面的内容以显示特定的分类帖子？
