public function reg_personal_details()

{ $reg_personal_details = array(

    // i also need a condition here to read the entered profile_id all that below data must be store in that id only//

    'profile_type' => $this->input->post('profile_type'),

    'profile_gender' => $this->input->post('profile_gender'),


    'profile_dob' => $this->input->post('profile_dob'),

    'profile_marital_status' => $this->input->post('profile_marital_status'),

    'profile_religion' => $this->input->post('profile_religion'),

    'profile_designation' => $this->input->post('profile_designation'),

'profile_project_designation' => $this->input->post('profile_project_designation'), );

    $this->db->update('profile',$reg_personal_details);

Answer 1

You Should write a java Script which would check if a particular element exists or not ie if its value is not null then generate a new row tags dynamically and set its value what we get in response of the query. For generating a tag dynamically you can refer the following page:-

Answer 2

we have a function to check whether data is present or not ie, empty()and we just need to use it in if loop like this "if (!empty($var name))" and can also use "if(empty($var name)) " so if there is no data then it doesn't show any error and if data is present in db it shows that data
