这是我的存档页面的代码。。

<?php
/*
Template Name: Archive Page
*/
?>

<?php get_header(); ?>
<div id ="maincontent"class = "group">
        <?php include\'leftsidebar.php\';?>
    <div id = "allcontent"class="archive">
    <?php if (have_posts()) : ?>

        <?php $post = $posts[0]; // Hack. Set $post so that the_date() works. ?>

        <?php /* If this is a category archive */ if (is_category()) { ?>
            <h2>Archive for the &#8216;<?php single_cat_title(); ?>&#8217; Category</h2>

        <?php /* If this is a tag archive */ } elseif( is_tag() ) { ?>
            <h2>Posts Tagged &#8216;<?php single_tag_title(); ?>&#8217;</h2>

        <?php /* If this is a daily archive */ } elseif (is_day()) { ?>
            <h2>Archive for <?php the_time(\'F jS, Y\'); ?></h2>

            <h2>Blog Archives</h2>

        <?php } ?>

        <?php include (TEMPLATEPATH . \'/inc/nav.php\' );?>

        <ul>
        <?php $i=0;?>

        <?php while (have_posts()) : the_post(); ?>

                <?php include (TEMPLATEPATH . \'/inc/meta.php\' ); ?>

                <div class="entry">

            dynamic_sidebar($Archive_Ads[rand(0, 2)]);
            endif;
            endif;
            ?>

        <?php endwhile; ?>
        </ul>



        <?php include (TEMPLATEPATH . \'/inc/nav.php\' ); ?>

<?php else : ?>

    <h2>Nothing found</h2>

<?php endif; ?>


    </div>
</div>
<?php get_footer(); ?>

现在我想要的是在不影响视频和图像的情况下，将文本限制为50个字，我想要显示我的图像和视频，有可能吗？

<?php
add_filter(\'the_content\', \'trim_content\');

function trim_content($content)
{
    if(is_archive())
    {
        //use your own trick to get the first 50 words. I\'m getting the first 100 characters just to show an example.
        $content = (strlen($content) <= 100)? $content : wp_html_excerpt($content, 100);
    }

    return $content;
}
