help with multiple input boxes in html and processing the post data with php

Question

I am creating a small site for my college where the instructors will be able to enter the marks and attendance of the students. I stuck at add records option where the instructor will enter the marks of students all at once(using pagination) or one by one(he enters once,clicks next and enters another).The input fields are marks, total classes, attended classes. Here are my questions and thanks in advance:

• how do i generate input boxes.say 40 students' marks can be entered in
  single page. then how do i give them (id)s and (name)s. later on how do i use the POST data to for each
  student?

• how should i paginate( any recommended class or code idea?)

• how do i implement the one by one option?

  thanks again.

Answer 1

1)

for ($i = 0; $i < 40; $i ++) {
    echo '<input name="mark[]" type="text" />';
}

2) look up jQuery http://jquery.com/ and jQuery Data Tables http://www.datatables.net/
