Merhabalar bir site hazırlıyorum. Sitenin kategori kısmında alt kategorileri sağ tarafta listeliyorum alt kategoriye tıklandığında

Kategori linki
http://localhost/site/helpfulinformation/endise

şeklinde bir link alt kategoriye tıkladığımda yandaki alt kategorilerin listesi aynı kalacak şekilde açıklama kısmını değiştiriyorum

Alt Kategori linki
http://localhost/site/helpfulinformation/endise/kaygi-bir-hastalikmi

şeklinde de alt kategori linki var helpfulinformation un controller dosyası

<?php

                view('404');
            }
        }
 
    }
}

ayrıca helpfulinformation un model dosyası

<?php
class Helpfulinformationmodel extends Database{
  
    public function getHelpfulinformation($url){
        $query = "SELECT * FROM helpfulinformation_tbl WHERE helpfulinformation_url = ?";
        $data = $this->getRow($query,array($url));
        return $data;
    }
    public function getHelpfulinformationSidebar($cat){
        $query = "SELECT * FROM helpfulinformation_tbl WHERE helpfulinformation_cat = ?";
        $data = $this->getRows($query,array($cat));
        return $data;
    }
    
    public function getHelpfulinformationReading($id){
        $query = "SELECT  readings_tbl.*, user_tbl.user_page_url FROM readings_tbl
        INNER JOIN user_tbl ON readings_tbl.readings_user_id = user_tbl.user_id
        WHERE readings_helpfulinformation_id = ?";
        $data = $this->getRows($query,array($id));
        return $data;
    }
    
}

bu şekilde yazdım hiç içime sinmiyor geleneksel sözümüz olan çalışıyorsa karışmayı mı uyguluyayım
veya
daha mantıklı bir çözüm önerisi olan var mı.
Teşekürler..
