有人可以帮助我,因为我是php的新手吗?
我正在运行一个使用智能模板引擎的电影网站,而我正在尝试做的是返回并显示所有类别的电影,但是当我使用这个时,它会为所有电影显示相同类别的“喜剧”
功能
public function getByPerma($perma, $lang=null){
$perma = mysql_real_escape_string($perma);
$movie = array();
$e = mysql_query("SELECT * FROM movies WHERE perma='$perma'") or die(mysql_error());
if (mysql_num_rows($e)>0){
$movie = $this->formatMovieData(mysql_fetch_assoc($e), $lang);
}
return $movie;
}
public function getMovieCategoryDetails($movieid,$lang=null){
$movieid = mysql_real_escape_string($movieid);
$e = mysql_query("SELECT * FROM movie_tags WHERE id IN (SELECT tag_id FROM movie_tags_join WHERE movie_id=$movieid)") or die(mysql_error());
$tags = array();
if (mysql_num_rows($e)){
while($s = mysql_fetch_array($e)){
$s['tag'] = json_decode($s['tag'],true);
if ($lang){
$s['tag'] = $s['tag'][$lang];
}
$tags[$s['id']] = $s;
}
}
return $tags;
}
调用函数
$movies = $movie->getByPerma($perma,$language);
if (empty($movies)) {
$movies = '';
} else {
$tags = $movie->getMovieCategoryDetails($movies['id'],$language);
if (!count($tags)){
$smarty->assign("tags","");
} else {
$smarty->assign("tags",$tags);
}
}
显示类别
{foreach from=$tags key=id item=val name=tags}
{$val.tag}
{/foreach}
我希望有人可以提供帮助吗?

我认为你的getByPerma()只返回1个电影信息,当把项目添加到数组时,[]丢失了:
$movie = $this->formatMovieData(mysql_fetch_assoc($e), $lang);
-->
$movie[] = $this->formatMovieData(mysql_fetch_assoc($e), $lang);
