php 列表页判断是否收藏

本帖最后由 mf0916 于 2015-10-22 18:54:06 编辑 在php文件里
<br />//$list 是个数组 包含每条信息的数据,然后写入以下代码;<br />	foreach($list as $value){<br />		$id=intval($value['id']);//list里面的信息ID<br />		$uid=intval($['uid']);//当前登录用户的ID<br />		$str = //查询数据库where likeid='$id' and uid='$uid';//有没有用户ID和当前信息ID<br />                          //查询条件就是这样,具体代码就不写了 (⊙﹏⊙)b<br />		$like = mysql_num_rows($str);	//判断出来的结果 $like大于0 表示已收藏<br />	}<br />//以上结果 输出 $like 能显示出 每条信息当前用户收藏情况是1还是0<br />//代码没有错误<br />
Copy after login

在html文件里
<br />{loop $list $a}<br />$a[id] - $a[title] -........<br />{/loop}<br />
Copy after login


问题是在html 文件里怎么判断啊?也就是说 把$like和列表的ID关联起来
//在html里面的 $list 写下如下代码 不成功
<br />{loop $list $a}<br />{if $like>0}已收藏{else}未收藏{/if}$a[id] - $a[title] -........<br />{/loop}<br />
Copy after login

------解决思路----------------------
看不出 $like 是从哪里来的,而且是个单值
如果是代码1中查询出来的那个,也应该放进 $list 中去吧?
对于每个 id 和 uid 对而言,$like 都是不一样的

------解决思路----------------------
$like 是在哪里赋值的?
