来自多个类别的帖子，但在第一个帖子中只有图片，其余的帖子只有帖子标题

时间：2012-10-17 作者：user22591

我很难只在每个类别的第一篇文章中设置特色图像，而其余的只显示文章标题。到目前为止，我一直设法用缩略图显示每个类别中的最新帖子，但我找不到方法，只能用缩略图显示第一篇帖子，其余的都是标题。有解决方案吗？这是我的代码：

                <?php
                    //get terms (category ids 11,2,33,34), then display one post in each term
                    $taxonomy = \'category\';//  e.g. post_tag, category
                    $param_type = \'category__in\'; //  e.g. tag__in, category__in
                    $term_args=array(
                      \'include\' => \'4,5,6,7\',
                      \'orderby\' => \'name\',
                      \'order\' => \'ASC\'
                    );
                    $terms = get_terms($taxonomy,$term_args);
                    if ($terms) {
                      foreach( $terms as $term ) {
                        $args=array(
                          "$param_type" => array($term->term_id),
                          \'post_type\' => \'post\',
                          \'post_status\' => \'publish\',
                          \'posts_per_page\' => 1,
                          \'caller_get_posts\'=> 1
                          );
                        $my_query = null;
                        $my_query = new WP_Query($args);
                        if( $my_query->have_posts() ) {
                          //Panikos Remove   echo \'Latest Post in \'.$taxonomy .\' \'.$term->name;
                          while ($my_query->have_posts()) : $my_query->the_post(); ?>
                            <div class="post_home_main">


                            <!--  Add timthumb to post featured image -->
                            <?php
                            $image_id = get_post_thumbnail_id();
                            $image_url = wp_get_attachment_url($image_id);
                            if ($image_url) {
                            ?>
                            <img src="<?php bloginfo(\'template_directory\'); ?>/scripts/timthumb.php?src=<?php echo $image_url; ?>&w=196&h=115&q=1000" alt="<?php the_title();?>" />
                             <!--  // Add timthumb to post featured image -->
                            <?php } else { ?>
                            <img src="<?php echo bloginfo(\'template_directory\') . \'/images/no-image.jpg\'; ?>" alt="No image available" class="panikosule" />
                            <?php } ?>


                            <a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
                            <?php the_excerpt(); ?> 
                            </div>
                           <?php
                          endwhile;
                        }
                      }
                    }
                    wp_reset_query();  // Restore global post data stomped by the_post().
                    ?>

一般注意事项：你不必使用（糟糕的）TimThumb工具。还有很多更好的东西，比如my（免费提供，开源）»Dynamic image resize« plugin.
2^{nd（还有afaik），你可以用船上的东西来做这件事，比如get_image_tag() 在你的情况下}
3^rd：不要将那么多变量放入全局名称空间。如果您真的认为无法解决此问题：请在它们前面加上一个唯一的字符串，如`wpse69602_`.\'include\' => \'4,5,6,7\'. 提示：大多数函数采用数组，而不是特殊的字符分隔字符串

我用来识别当前循环帖子编号的kool不是$flag. 这是$wp_query 对象：Thecurrent_post, 这是WordPress已经设置的标志。

<div class="container">
<?php
$terms = get_terms(
     \'category\'
    ,array(
         \'include\' => array( \'4,5,6,7\' )
        ,\'orderby\' => \'name\'
        ,\'order\'   => \'ASC\'
    )
);
if ( ! empty( $terms ) )
{
    foreach( $terms as $term ) 
    {
        $my_query = new WP_Query( array(
             \'category__in\'     => array( $term->term_id )
            ,\'post_type\'        => \'post\'
            ,\'post_status\'      => \'publish\'
            ,\'posts_per_page\'   => 1
            ,\'caller_get_posts\' => 1

        if ( $my_query->have_posts() )

            while ( $my_query->have_posts() )
            {

就在while ($my_query->have_posts()) 添加$flag = false;, 然后将您的特色图像代码包装在另一个if条件中，如下图所示

if( !$flag ) {

$flag = true;

// put all you featured image code here

}

现在更改post_per_page 参数设置为更高的数字。图像代码仅在每个类别的循环第一次运行时执行

UPDATE

<?php
if( !$flag ) {
    $flag = true;
?>

                        <!--  Add timthumb to post featured image -->
                        <?php
                        $image_id = get_post_thumbnail_id();
                        $image_url = wp_get_attachment_url($image_id);
                        if ($image_url) {
                        ?>
                        <img src="<?php bloginfo(\'template_directory\'); ?>/scripts/timthumb.php?src=<?php echo $image_url; ?>&w=196&h=115&q=1000" alt="<?php the_title();?>" />
                         <!--  // Add timthumb to post featured image -->
                        <?php } else { ?>
                        <img src="<?php echo bloginfo(\'template_directory\') . \'/images/no-image.jpg\'; ?>" alt="No image available" class="panikosule" />
                        <?php } ?>


<?php } ?>

感谢kaiser和Mridul的回复。我通过以下代码实现了我想要的：

<div class="categorys_box">
   <!-- Query only the first post -->
   <?php $cat4 = new WP_Query(\'cat=4&showposts=1\');
      if($cat4->have_posts()) : while($cat4->have_posts()) : $cat4->the_post(); ?>
      <!-- First post only content area -->
      <div class="first_post">

                <?php
                $image_id = get_post_thumbnail_id();
                $image_url = wp_get_attachment_url($image_id);
                if ($image_url) {
                 ?>
                <img src="<?php bloginfo(\'template_directory\'); ?>/scripts/timthumb.php?src=<?php echo $image_url; ?>&w=196&h=115&q=1000" alt="<?php the_title();?>" /> 
                <!--  // Add timthumb to post featured image -->
                <?php } else { ?>
                <img src="<?php echo bloginfo(\'template_directory\') . \'/images/no-image.jpg\'; ?>" alt="No image available" class="panikosule" />
                <?php } ?>
                <a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title_attribute(); ?>">
                <?php the_title(); ?>
                </a>
                <?php the_excerpt(); ?>

      </div><!-- //first_post -->

      <?php endwhile; endif; ?>
      <!-- Query the rest posts. Offset = -1 from the above  -->
      <?php $sidecat4 = new WP_Query(\'cat=4&showposts=2&offset=1\');
      if($sidecat4->have_posts()) : while($sidecat4->have_posts()) : $sidecat4->the_post(); ?>
       <!-- Rest posts content area -->
     <div class="rest_post">

      <a href="<?php the_permalink() ?>">
        <?php the_title() ?>
       </a>

        </div><!-- //rest_posts  -->
      <?php endwhile; endif; ?>
      <?php wp_reset_query();  // Restore global post data stomped by the_post().?>
    </div><!-- //categorys_box-->
