如何在WordPress循环中输出缩略图两次 - How to output thumbnail twice in a WordPress loop

How to output thumbnail twice in a WordPress loop

好的，我有一个投资组合页面。每个项目组合项都附加了缩略图。我想要的是两次打印出第一篇文章中的第一个缩略图。一个在开头，另一个在结尾。比如：image_1，image_2，image_3，image_4，然后再次image_1。

我的代码是：

<div class="main-interior portfolio" id="portfolio-big-pics" style="display: block;">
<?php $args = array( 'post_type' => 'portfolio', 'order' => 'dsc');
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php $extraFirstClass = $loop->current_post == '0' ? ' main-image-porfolio-main' : ''; ?>
<?php 
$attributes = array(
    "class" => "main-image portfolio " . $extraFirstClass,
    "id" => "photo_{$post->ID}",
);
the_post_thumbnail("portfolio_thumb", $attributes);
?>
<?php endwhile; ?> 
<?php rewind_posts(); ?> 

    <div class="portfolio-box">
        <h5>Portfolio</h5>
        <ul class="item-list" id="portfolio-list">
        <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
        <li><a href="<?php the_permalink(); ?>" rel="<?php echo $post->ID; ?>"><?php the_title(); ?></a>
        </li>
        <?php endwhile; ?>              
        </ul>
    </div>
</div>

我该怎么做？

正如我之前在这里回答的那样，我会使用 PHP for 。但是，如果出于某种原因您不希望这样做，我认为您不需要为此求助于两个循环。您可以执行以下操作：

<?php
$args = array( 'post_type' => 'portfolio', 'order' => 'dsc');
$loop = new WP_Query( $args );
$first = $loop->posts[0];
$attributes = array(
    "class" => "main-image portfolio",
    "id" => "photo_{$loop->posts[$i]->ID}",
);
<div class="main-interior portfolio" id="portfolio-big-pics" style="display: block;">
    for( $i = 0; $i < count($loop->posts); $i++ ) {
        $attrs = $attributes;
        $attrs["class"] .= $i === 0 ? ' main-image-portfolio-main' : '';
        echo get_the_post_thumbnail( $loop->posts[$i]->ID, "portfolio_thumb", $attrs );
    }
    echo get_the_post_thumbnail( $first->ID, "portfolio_thumb", $attrs );
    ?>
    <div class="portfolio-box">
        <h5>Portfolio</h5>
        <ul class="item-list" id="portfolio-list">
            <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
            <li>
                <a href="<?php the_permalink(); ?>" rel="<?php echo $post->ID; ?>"><?php the_title(); ?></a>            
            </li>
            <?php endwhile; ?>
            <li>
                <a href="<?php echo get_permalink($first->ID);?>" rel="<?php echo $first->ID; ?>"><?php echo $first->post_title;?></a>
            </li>  
        </ul>
    </div>
</div>

这是代码，根据您的需要进行编辑：

$(document).ready(function()
{
   var imagesrc = $(".example post's image class").attr("src");
   $(".the container or post after which you want to put your image").appendTo("<img src='"+imgsrc+"' alt='image' />");
});
