产品细化按类别和地区过滤

Question

我目前正在尝试按类别，条件，区域和价格实施产品细化过滤器，我将此网站http://phpcooker.com/product-search-filter-in-php作为参考。但每当我选中一个方框时（例如，我检查一个属于它的2或3个产品的类别），它会在URL中获取catId并且页面只刷新并且不进行过滤。它只是在一侧重新组合相同类别的产品，而在另一侧保留不属于我检查类别的产品。

我有4张桌子 广告表，包含adId，title，catId，regionId，price，condition，description catId，catName的类别表 regionId，regionName的区域表 图像表与imageId，adId，路径，预览

对不起我的英语，但我迫切需要找到解决方案。？

这是我的班级文件

public function getAllCat(){
    $query = "SELECT * FROM category ORDER BY catId";
    $result = $this->db->select($query);
    return $result;

}
    public function getAllRegion(){
    $query = "SELECT * FROM region ORDER BY regionId";
    $result = $this->db->select($query);
    return $result;
}
    public function getAllAds(){
    $query = "SELECT * FROM ads ORDER BY adId DESC";
    $result = $this->db->select($query);
    return $result;
}

public function getPreviewImage($id){
    $query = "SELECT * FROM images WHERE adId = $id AND preview = '1' ";
    $image = $this->db->select($query);
    return $image;

}
