Solved in this way :

PHP Code:

if(!empty($post['data_da'])){

                $data_da = date_local_format_to_iso($post['data_da']);
            
            }else{

                $data_da ='2000/01/01';
            }

            if(!empty($post['data_a'])){

                $data_a = date_local_format_to_iso($post['data_a']);
            
            }else{

                $data_a ='2100/01/01';
            }

            $array_query=[];

            if(!empty($post['id_tipo_spesa'])){

                $id_tipo_spesa = $post['id_tipo_spesa'];
                
                $array_query ['id_tipo_spesa']    = $id_tipo_spesa;
            }
                
            if(!empty($post['id_tipo_pagamento'])){

                $id_tipo_pagamento = $post['id_tipo_pagamento'];
                
                $array_query ["id_tipo_pagamento"]  =  $id_tipo_pagamento;
            }
                

                
            if(!empty($post['id_autisti_interni'])){

                $id_autisti_interni = $post['id_autisti_interni'];
                
                $array_query ["id_autisti_interni"] =  $id_autisti_interni;
            }
                                
            if(!empty($post['id_mezzi'])){

                $id_mezzi = $post['id_mezzi'];
                
                $array_query ["id_mezzi"] =  $id_mezzi;
            }
                

            if(!count($array_query)){
                $array_query="id!=0";
            }
                


            $spese = $spese_model->where('data>=',$data_da)
                                ->where('data<=',$data_a)
                                ->where($array_query)
                                ->findAll();


            
            //log_message('debug',$spese_model->getLastQuery());
            $record_totali =$spese_model->countAllResults();
