You are going to have to re-write the libraries and also there in no output library in CodeIgniter 4.

For setting headers etc. read the CodeIgniter 4 User Guide.

What did you Try? What did you Get? What did you Expect?

You are going to have to re-write the libraries and also there in no output library in CodeIgniter 4.

Could you help me update this class? there would use model.

PHP Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Menus {

  public $listMenus;
  public $listSeo;

  public function __construct(){
    $this->CI =& get_instance();
    $this->CI->load->database('default');
    $this->set();
  }

  public function set(){

    $query       = $this->CI->db->select('*')->from( "menu" )->where("parente", 0)->where("ativo", 1)->order_by('posicao', 'asc')->get();
    $menusPai    =  ( $query->num_rows() > 0 )? $query->result_array() : false;
    $query2      =  $this->CI->db->select('*')->from( "menu" )->where("parente > 0")->where("ativo", 1)->order_by('posicao', 'asc')->get();
    $menusFilhos = ( $query2->num_rows() > 0 )? $query2->result_array() : false;

    $menus = array();

    foreach ( $menusPai as $key => $value) {
      $this->listSeo[$value['link']]['pagina_titulo'] =  $value['pagina_titulo'];
      $this->listSeo[$value['link']]['pagina_keywords'] =  $value['pagina_keywords'];
      $this->listSeo[$value['link']]['pagina_description'] =  $value['pagina_description'];
      $menus[$value['id']]['filhos'] = array();
      $menus[$value['id']]['dados'] = $value;
      if($menusFilhos){
        foreach ($menusFilhos as $k => $v) {
          if($v['parente'] == $value['id']){
            $this->listSeo[$v['link']]['pagina_titulo'] =  $v['pagina_titulo'];
            $this->listSeo[$v['link']]['pagina_keywords'] =  $v['pagina_keywords'];
            $this->listSeo[$v['link']]['pagina_description'] =  $v['pagina_description'];              
            $menus[$value['id']]['filhos'][] = $v; 
          }
        }
      }
    }

    $this->listMenus = $menus;

  }

  public function get(){

    return $this->listMenus;

  } 

  public function seo($tag){

    $uri = ($this->CI->uri->uri_string() == '')? '/' : $this->CI->uri->uri_string();
    return $this->listSeo[$uri][$tag];
    
  }


} 


my set function, I think I managed to update I have a problem with the seo and get function.
could you tell me if this method is right?

PHP Code:

public function set(){
    $db      = \Config\Database::connect();
    $tb_menu = $db->table('menu');
   // $builder->db->table('menu');
    $tb_menu->select('*');
    $tb_menu->where('parente', 0);
    $tb_menu->where('ativo', 1);
    $tb_menu->orderBy('posicao', 'ASC');
    $dados = $tb_menu->get()->getResultArray();
    
    if(is_array($dados)){
      $menusPai = $dados;
    }

    $builder2 = $db->table('menu');
    // $builder->db->table('menu');
    $builder2->select('*');
    $builder2->where('parente', 0);
    $builder2->where('ativo > 0');
    $builder2->orderBy('posicao', 'ASC');
    $query2 = $builder2->get()->getResultArray();
    if(is_array($query2)){
      $menusFilhos = $query2;
    }
    $menus = array();
    foreach ( $menusPai as $key => $value) {
      $this->listSeo[$value['link']]['pagina_titulo'] =  $value['pagina_titulo'];
      $this->listSeo[$value['link']]['pagina_keywords'] =  $value['pagina_keywords'];
      $this->listSeo[$value['link']]['pagina_description'] =  $value['pagina_description'];
      $menus[$value['id']]['filhos'] = array();
      $menus[$value['id']]['dados'] = $value;
      if($menusFilhos){
        foreach ($menusFilhos as $k => $v) {
          if($v['parente'] == $value['id']){
            $this->listSeo[$v['link']]['pagina_titulo'] =  $v['pagina_titulo'];
            $this->listSeo[$v['link']]['pagina_keywords'] =  $v['pagina_keywords'];
            $this->listSeo[$v['link']]['pagina_description'] =  $v['pagina_description'];              
            $menus[$value['id']]['filhos'][] = $v; 
          }
        }
      }
    }
    $this->listMenus = $menus;
  } 


This is not tested! You really should sit down and read the CodeIgniter User Guide.
