通过摸索,笔者请mzsongyan兄弟为大家写下了在emlog顶级列表页下调用二级栏目标题及文章内容的方法,实现效果如下图所示:

这个方法是mzsongyan兄弟无私奉献出来的,所以笔者不敢私藏,也从来没有私藏的意思,一方面是为了彰显分享的初衷,另一方面是为了让更多的人享受mzsongyan兄弟为大家带来的牛气代码。好了,废话太多,相关代码如下:

一、放置在modul.php中的代码模块:

<?PHP
function is_sub_category($pid){
	$db = Database::getInstance();
    $sql = "SELECT sid,sortname FROM " . DB_PREFIX . "sort WHERE pid = $pid";
    $res = $db->query($sql);
    $num = $db->num_rows($res);
    return $num;
}
function get_sub_category_post($pid, $num = 10){
        $db = Database::getInstance();
        $sql = "SELECT sid,sortname FROM " . DB_PREFIX . "sort WHERE pid = $pid";
        $res = $db->query($sql);
        while ($row = $db->fetch_array($res)) {
                echo "<h2><a href='" . Url::sort($row['sid']) . "'>" . $row['sortname'] . "</a></h2>";
                get_post_list($row['sid'], $num);
        }
}
function get_post_list($sid, $num = 10){
        $db = Database::getInstance();
        $sql = "SELECT gid,title FROM " . DB_PREFIX . "blog WHERE sortid = $sid and type = 'blog' and hide = 'n' and password = '' LIMIT 0 , $num";
        $res = $db->query($sql);
        echo '<ul>';
        while ($row = $db->fetch_array($res)){
                echo "<li><a href='" . Url::log($row['gid']) . "'>" . $row['title'] . "</a></li>";
        }
        echo '</ul>';
}
?>

二、在log_list.php中将如下代码放置在内容区域,是替换掉原来模板中的代码。如下:

<?php
$abc = false;
if(! empty($sortid)){
	$abc = is_sub_category($sortid) > 0 ? false : true;
}
if(blog_tool_ishome() OR $abc):
	if (!empty($logs)):
	foreach($logs as $value): 
	?>
		<h2><?php topflg($value['top'], $value['sortop'], isset($sortid)?$sortid:''); ?><a href="<?php echo $value['log_url']; ?>"><?php echo $value['log_title']; ?></a></h2>
		<p class="date"><?php echo gmdate('Y-n-j', $value['date']); ?> <?php blog_author($value['author']); ?> 
		<?php blog_sort($value['logid']); ?> 
		<?php editflg($value['logid'],$value['author']); ?>
		</p>
		<?php echo $value['log_description']; ?>
		<p class="tag"><?php blog_tag($value['logid']); ?></p>
		<p class="count">
		<a href="<?php echo $value['log_url']; ?>#comments">评论(<?php echo $value['comnum']; ?>)</a>
		<a href="<?php echo $value['log_url']; ?>">浏览(<?php echo $value['views']; ?>)</a>
		</p>
		<div style="clear:both;"></div>
	<?php endforeach;else:?>
	<h2>未找到</h2>
	<p>抱歉,没有符合您查询条件的结果。</p>
	<?php endif;?>
	<div id="pagenavi"><?php echo $page_url;?></div>
<?php else: ?>
<?php get_sub_category_post($sortid); ?>
<?php endif; ?>
