Problem with Form Validation when update field

    Dear CodeIgniter,

    My name is PEN Vannak. I am a beginning developer and start my project with the CodeIgniter at the first time.

    I have the problem with the form validation when I update the field.

    Lets me describe about my problems:
      -I have the page Member Management.
      -I want to update my field in this page. But when I edit, first I have to check the empty field and check valid email. If I edited in the correct format(fill all required field and right email format), it is successful.
      -But if I edited in the wrong format(didn’t fill all required field, or wrong email format), I want it to show the error message, and show the field that I should edit.

    I have found that in the page viewers, I have input hidden field call(mem_id) to call the field for edit.

    In the controllers, I have the function called “edit_member” that have the one parameter is “mem_id”.

    When I edit first, it call the field into function with the “mem_id” according to the field I have selected. But when it I input the incorrect form format, this function will be called again and include eith the “mem_id”. In this case, the “mem_id” is equal to 0. So it could not select the field for edit again.

    If any one understand this problem, or have experience with this. Please explain me!

    I’m waiting to get all advice from you all.

    Best regard,
    PEN Vannak.
