1.写一个方法专门做抓取图片。
function getImgs($content,$order='ALL'){ $pattern="/<img.*?src=[\'|\"](.*?(?:[\.gif|\.jpg]))[\'|\"].*?[\/]?>/"; preg_match_all($pattern,$content,$match); if(isset($match[1])&&!empty($match[1])){ if($order==='ALL'){ return $match[1]; } if(is_numeric($order)&&isset($match[1][$order])){ return $match[1][$order]; } } return ''; } 2.利用查询出列表页的文章ID去查询内容
$result = $db->query("SELECt ".$MOD['fields']." FROM {$table} WHERe $condition ORDER BY $order LIMIT $offset,$pagesize"); while($r = $db->fetch_array($result)) { if($kw) $r['title'] = str_replace($kw, '<b>'.$kw.'</b>', $r['title']); $r['linkurl'] = mobileurl($moduleid, 0, $r['itemid']); $r['date'] = timetodate($r[$time], $page < 4 ? 2 : 3); $lists[] = $r; } // 获取内容 foreach($lists as $key=>$val){ $t = $db->query("SELECT content FROM taomodi_article_data_21 WHERe itemid=".$val['itemid']); while($res = $db->fetch_array($t)){ $content = video5($res['content']); $content = str_replace('<hr/>', '', $content); //调用方法 $val['content'] = getImgs($content); $lists[$key] = $val; } } // var_dump($lists);die; 3.模板中使用
{loop $lists $vv}
<li>
<a href="{$vv[linkurl]}">
<div>
<dt>{$vv[title]}</dt>
<dd>{php $res = dsubstr($vv['introduce'],'80','...');echo str_replace(' ','',$res);}</dd>
</div>
<div>
<dd>
{if $vv[content]}
{loop $vv[content] $k $v}
{php if($k >=3) break;}
<img src="http://www.dtmuban.com/course/{$v}"/>
{/loop}
{/if}
</dd>
</div>
<div></div>
</a>
</li>
{/loop}
