function create(){ 

       // create word file 
       $this->load->library('PHPWord'); 
       $case_num1 = $this->input->post('case_num1'); 
       $case_num2 = $this->input->post('case_num2'); 
       $case_num3 = $this->input->post('case_num3'); 
       $case_date = $this->input->post('case_date'); 
       $case_subject = $this->input->post('case_subject'); 
       $case_system = $this->input->post('case_system'); 
       $case_brief = $this->input->post('case_brief'); 
       $case_facts = $this->input->post('case_facts'); 
       $case_reasons = $this->input->post('case_reasons'); 
       $case_staffs = $this->input->post('case_staff'); 

       $this->word_validation_input($case_num1,$case_num2,$case_num3,$case_date,$case_subject,$case_system,$case_brief,$case_facts,$case_reasons,$case_staffs); 

}
