On dropdown change the textbox value get changed i need to assign this textbox value to session without any form in codeigniter

Answer 1

You can use jquery to trigger the change of value. and then run an ajax to set session data

$('#lang').change(function(){
   var val = $(this).val();
   $.ajax({
       url: "<?=site_url('your_controller/your_method')?>",
       type: "POST",
       data: {val: val},
       success: function(res){
          // your code after the ajax completed
       }
   });
});

now at controller create a new method which will set session data

functoin your_method(){
   $this->session->set_userdata('user_lang', $this->input->post('val'));
}
