多个帖子缩略图插件-需要代码帮助

时间：2011-12-01 作者：tobeeornot

我在运行这个插件时遇到了一些问题，但即使在阅读了过去的条目之后，也没能成功运行它。如果您能看看代码是否正确，我将不胜感激。

函数中的代码。php：

\'// Add secondary thumbnail (featured image) in posts */
if (class_exists(\'MultiPostThumbnails\')) { 
new MultiPostThumbnails(array ( 
        \'label\' => \'Secondary Image\', 
        \'id\' => \'secondary-image\', 
        \'post_type\' => \'post\' )
);
new MultiPostThumbnails(array(
        \'label\' => \'Tertiary Image\',
        \'id\' => \'tertiary-image\', )
 );
new MultiPostThumbnails(array(
        \'label\' => \'Quaternary Image\',
        \'id\' => \'quaternary-image\', )
);
}
add_image_size(\'post-secondary-image-thumbnail\', 176, 58, true);
add_image_size(\'post-tertiary-image-thumbnail\', 176, 58, true);
add_image_size(\'post-quaternary-image-thumbnail\', 176, 58, true);\'
相关模板中的代码（我已经发布了整个模板代码，因为我认为您需要完整查看）：

<?php

/*
    Template Name: Home
*/

?>
<?php get_header(); ?>

<div id=\'main-content\'>

        <h2>What We Do</h2>

        <ul id="we-do">

    <?php query_posts("posts_per_page=1&post_type=page&page_id=168"); 
             the_post (); ?>
        <!--If you want to refer to the child of parent page, use "post_parent=" -->
        <li>
            <h3><?php the_title(); ?></h3>
             <?php the_excerpt(); ?>
             <?php if (class_exists(\'MultiPostThumbnails\')
    && MultiPostThumbnails::has_post_thumbnail(\'post\', \'secondary-image\')) :
    MultiPostThumbnails::the_post_thumbnail(\'post\', \'secondary-image\'); endif; ?>
            <a href="<?php the_permalink(); ?>" class="button">View More</a>
        </li>

    <?php query_posts("posts_per_page=1&post_type=page&page_id=236"); the_post(); ?>

        <li>
            <h3><?php the_title(); ?></h3>
            <p><?php the_excerpt(); ?></p>
            <?php if (class_exists(\'MultiPostThumbnails\')
   && MultiPostThumbnails::has_post_thumbnail(\'post\', \'tertiary-image\')) :
    MultiPostThumbnails::the_post_thumbnail(\'post\', \'tertiary-image\'); endif; ?>
            <a href="<?php the_permalink(); ?>" class="button">View More</a>
       </li>

  <?php query_posts("posts_per_page=1&post_type=page&page_id=240"); the_post(); ?>

        <li>    

            <h3><?php the_title(); ?></h3>
            <?php the_excerpt(); ?>
             <?php if (class_exists(\'MultiPostThumbnails\')
    && MultiPostThumbnails::has_post_thumbnail(\'post\', \'quaternary-image\')) :
    MultiPostThumbnails::the_post_thumbnail(\'post\', \'quaternary-image\'); endif; ?>
            <a href="<?php the_permalink(); ?>" class="button">View More</a>
      </li>
         </ul>

</div><!--END main-content-->

<?php get_sidebar(); ?>

<?php get_footer(); ?>
我还想对图像应用一个类，但不确定将数组放置在何处。

可能需要注意的是，我也在运行同样注册在函数模板中的特色图像功能。

下面是使用您提供的代码的完整示例：

用于您的功能。php文件：

<?php
// Add secondary thumbnail (featured image) in posts */
if (class_exists(\'MultiPostThumbnails\')) { 
 new MultiPostThumbnails(array ( 
   \'label\' => \'Secondary Image\', 
   \'id\' => \'secondary-image\', 
   \'post_type\' => \'post\' )
   );
  new MultiPostThumbnails(array(
   \'label\' => \'Quaternary Image\',
   \'id\' => \'quaternary-image\', )
   );
  new MultiPostThumbnails(array(
   \'label\' => \'Tertiary Image\',
   \'id\' => \'tertiary-image\', )
   );
 }
add_image_size(\'post-secondary-image-thumbnail\', 176, 58, true);
add_image_size(\'post-tertiary-image-thumbnail\', 176, 58, true);
add_image_size(\'post-quaternary-image-thumbnail\', 176, 58, true);
?>
对于您的页面模板：

<?php
/*
Template Name: Home
*/
?>
<?php get_header(); ?>
<div id=\'main-content\'>
<h2>What We Do</h2>
  <ul id="we-do">
    <?php 
      query_posts("posts_per_page=1&post_type=page&page_id=168");
      the_post (); ?>
    <!--If you want to refer to the child of parent page, use "post_parent=" -->
    <li>
      <h3><?php the_title(); ?></h3>
        <?php the_excerpt(); ?>
      <?php 
        MultiPostThumbnails::the_post_thumbnail(\'post\', \'secondary-image\', NULL,  \'post-secondary-image-thumbnail\');
      ?>
      <a href="<?php the_permalink(); ?>" class="button">View More</a>
    </li>
    <?php 
      query_posts("posts_per_page=1&post_type=page&page_id=236"); 
      the_post(); 
      ?>
      <li>
        <h3><?php the_title(); ?></h3>
        <p><?php the_excerpt(); ?></p>
      <?php 
        MultiPostThumbnails::the_post_thumbnail(\'post\', \'quaternary-image\', NULL,  \'post-quaternary-image-thumbnail\');
        ?>
        <a href="<?php the_permalink(); ?>" class="button">View More</a>
      </li>
    <?php query_posts("posts_per_page=1&post_type=page&page_id=240"); the_post(); ?>
    <li>
    <h3><?php the_title(); ?></h3>
    <?php the_excerpt(); ?>
    <?php 
      MultiPostThumbnails::the_post_thumbnail(\'post\', \'tertiary-image\', NULL,  \'post-tertiary-image-thumbnail\');
      ?>
    <a href="<?php the_permalink(); ?>" class="button">View More</a>
    </li>
  </ul>
</div><!--END main-content-->
<?php get_sidebar(); ?>
<?php get_footer(); ?>

要使代码正常工作，需要在函数中将代码更改为此。php文件：

<?php
// Add secondary thumbnail (featured image) in posts */
if (class_exists(\'MultiPostThumbnails\')) { 
 new MultiPostThumbnails(array ( 
   \'label\' => \'Secondary Image\', 
   \'id\' => \'secondary-image\', 
   \'post_type\' => \'post\' )
   );
  new MultiPostThumbnails(array(
   \'label\' => \'Quaternary Image\',
   \'id\' => \'quaternary-image\', )
   );
  new MultiPostThumbnails(array(
   \'label\' => \'Tertiary Image\',
   \'id\' => \'tertiary-image\', )
   );
 }
add_image_size(\'post-secondary-image-thumbnail\', 176, 58, true);
add_image_size(\'post-tertiary-image-thumbnail\', 176, 58, true);
add_image_size(\'post-quaternary-image-thumbnail\', 176, 58, true);
?>

Then to use the code in the template you would use this:

<?php 
  MultiPostThumbnails::the_post_thumbnail(\'post\', \'secondary-image\', NULL,  \'post-secondary-image-thumbnail\');
  ?>
缩略图将自动添加以下类别：

.attachment-post-secondary-image-thumbnail
这将随着您注册的每个附加大小而更改。它将具有您在函数中指定的图像大小名称的类。php文件。

结束

Multiple Page Templates & CSS

在使用多个页面模板的主题上处理CSS的最佳实践是什么？例如：我将有一个全宽页面模板和一个两列页面模板。最好只在单个CSS中调用容器（#fullWidthContainer vs.#twoColumnContainer）还是为每个页面模板提供单独的CSS文件更好？
