我有以下带有输出内容的博客模板。我已放置<!--more-->

然而，它似乎没有发挥作用，

是否需要在函数中包含任何内容才能使其正常工作？

Code Of my Blog Template

<?php
/*
Template Name: Blog Template
*/
 ?>

<?php get_header();?>
<?php echo get_the_post_thumbnail($post->ID, \'single-post-thumbnail\'); ?>
<div id="maincontentwrap" role="main">
<?php query_posts(\'showposts=5\'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
 <div class="datebackground"><span class="day"><?php echo get_the_date(\'j\'); ?></span>    <span class="month"><?php echo get_the_date(\'M\'); ?></span></div>
<div class="postsh1"><?php echo get_the_title(); ?></div>
<div id="blogwrapper">
Written by <?php the_author_posts_link() ?> in <?php the_category(); ?>
<?php the_content(\'read more...\'); ?>

<br>
<div class="pagedivider"></div>
</div>  
<?php endwhile; else: ?>
<p><?php _e(\'Sorry, no posts matched your criteria.\'); ?></p>
<?php endif; ?>
</div><!-- #content -->
<?php get_footer(); ?>

EDIT

我在《二十一世纪》主题中发现了这一点，我尝试将其改编为我自己的主题，但实际代码中的错误。。。

function DTheme_excerpt_length( $length ) {
return 40;
}
add_filter( \'excerpt_length\', \'DTheme_excerpt_length\' );

if ( ! function_exists( \'DTheme_continue_reading_link\' ) ) :
/**
 * Returns a "Continue Reading" link for excerpts
 *
 * @since Twenty Ten 1.0
 * @return string "Continue Reading" link
 */
function DTheme_continue_reading_link() {
return \' <a href="\'. get_permalink() . \'">\' . __( \'Continue reading <span class="meta-  nav">&rarr;</span>\', \'DTheme\' ) . \'</a>\';
}
endif;

/**
 * Replaces "[...]" (appended to automatically generated excerpts) with an ellipsis and twentyten_continue_reading_link().
 *
 * To override this in a child theme, remove the filter and add your own
 * function tied to the excerpt_more filter hook.
 *
 * @since Twenty Ten 1.0
 * @return string An ellipsis
 */
function DTheme_auto_excerpt_more( $more ) {
return \' &hellip;\' . DTheme_continue_reading_link();
}
add_filter( \'excerpt_more\', \'DTheme_auto_excerpt_more\' );
?>

这是一种情况，我需要适应上述工作？

EDIT

大家好，这似乎是部分工作后，惊人的帮助下面，但它仍然没有显示在内容包装和图像，例如正在调整大小。。。请立即查看我的代码和屏幕截图
