hola, tengo un problema cuando paso el valor del botón... cuando hago clic en el botón, quiero mostrar los detalles que dependen del botón, pero supongo que el valor del botón no pasa de la vista al controlador. ayuda,,,

 //view(button) <div class="marketer"> <?php foreach($marketer_list as $marketer){ ?> <button type="button" class="mid" name= "posting_user_id" value="<?=$marketer->id?>"><?=$marketer->username?></button> <?php }?> </div> $(document).ready(function () { $('.mid').click(function(){ var id = $(this).attr('value'); alert(id); if (id=='<?=$detail->posting_user_id?>') { $(".show_posting").show(); }else{ alert("no info"); } }); }); //controller $posting_user_id = $this->input->post('posting_user_id'); $data['daily'] = $result; $data['posting'] = $this->posting_models->get_manage_hospital_list($posting_user_id); $this->load->view('posting',$data); //model function get_manage_hospital_list($posting_user_id){ $this->db->select('u.hosp_name,p.*'); $this->db->from('users as u'); $this->db->join('posting_plan as p', 'u.id=p.hospital_id'); $this->db->where('posting_user_id',$posting_user_id); $this->db->order_by('p.report_day','asc'); return $this->db->get()->result(); }
