Emlog实现调用分类下第一篇文章图片函数分享
效果图大家先看看
的在模板文件下的module.php下添加如下函数
<?php //分类文章调用 function sort_log($sortid){ $db = MySql::getInstance(); $sql = $db->query ("SELECT * FROM ".DB_PREFIX."blog WHERE sortid='$sortid' AND type='blog' AND hide='n' order by date DESC limit 0,1"); $row = $db->fetch_array($sql); if (!empty($row['excerpt'])){ preg_match_all("/<img.*?src="(.*?)"[^>]*>/i", $row['excerpt'], $match); if(empty($match[0][0])) {preg_match_all("/<img.*?src="(.*?)"[^>]*>/i", $row['content'], $match);} }else{preg_match_all("/<img.*?src="(.*?)"[^>]*>/i", $row['content'], $match);} $logpost = !empty($row['excerpt']) ? $row['excerpt'] : ''.$row['content'].''; $num = rand(1,$imgnum); $img = isset($match[0][0]) ? $match[0][0] : '<img src="'.TEMPLATE_URL.'images/shuyong_net/'.$num.'.jpg">'; $content = strip_tags($logpost,''); $content = mb_substr($content,0,68,'utf-8');// $out .='<div class="sort-tw"><div class="sort-img"><a href="'.Url::log($row['gid']).'" title="'.$row['title'].'" >'.$img.'</a></div> <div class="sort-tt"><a href="'.Url::log($row['gid']).'" title="'.$row['title'].'" >'.$row['title'].'</a></div><div class="sort-nr">'.$content.'...</div></div> '; $sort_log_num = $sort_log_num -1; $logs = $db->query ("SELECT * FROM ".DB_PREFIX."blog WHERE sortid='$sortid' AND type='blog' AND hide='n' order by date DESC limit 1,10");//1表示从第2篇文章开始，10为数量 while ($trow = $db->fetch_array($logs)){ $date = gmdate('m-d', $trow['date']); $trow['title'] = mb_substr($trow['title'],0,180,'utf-8'); $out .='<li><p><a href="'.Url::log($trow['gid']).'" title="'.$trow['title'].'">'.$trow['title'].'</a></p><span>'.$date.'</span></li> '; }echo $out;}?>
Emlog模板文件log_list.php下使用如下代码
<?php global $CACHE;$sort_cache = $CACHE->readCache('sort'); ?>
<?php echo $sort_cache[1]['sortname'];?>调用分类名称，其中[1]代表分类id
<?php sort_log(1); ?>
最后写上css就ok，css文件自己折腾吧
分类图文显示
<?php //分类图文 function home_cp(){ $ysort = array(1,2,3);//分类id $num = 10;//显示数量 $db = MySql::getInstance();global $CACHE; $sort_cache = $CACHE->readCache('sort');foreach($ysort as $key => $i){$key = $key+1;?> <div class="side product"> <div class="title"><p><?php echo $sort_cache[$i]['sortname'];?></p><a href="<?php echo Url::sort($i);?>" title="<?php echo $sort_cache[$i]['sortname'];?>"><span></span></a></div> <?php $logs = $db->query("SELECT * FROM ".DB_PREFIX."blog WHERE sortid='$i' AND type='blog' AND hide='n' order by date DESC limit 0,$num"); while($value = $db->fetch_array($logs)){$img_url = TEMPLATE_URL.'images/news.jpg';if(img_fj($value['gid'])){$img_url = img_fj($value['gid']);}elseif(img_zw($value['content'])){$img_url = img_zw($value['content']);}else{$img_url;}?> <ul class="zx"><li><a href="<?php echo Url::log($value['gid']);?>"><img src="<?php echo $img_url;?>" /><p><?php echo $value['title'];?></p></a></li></ul><?php }?></div><?php }}?>
