retrieve and get input from same page using php

[glady]

Hi,
I would like to have a php form that gets input from
user and display data if they have already entered for
that particular record in the same form.
For example, if i have a form with 20 fields,
if the user already entered 5 (values)field, then it should retrieve
5 values in form as read-only format and remaining 15
fields should be empty to get input from user.
This time if user enters 3 values, next time if the user open the
form, the form should retrieve 8 values and remaining as empty.
Each time if the user enters and adds input, it should store the value
once in table but not twice.

How i can do this using PHP and MySQL.
Thanks.

Read variables from table
Display the form with an for each inpuyt field to generate on the screen:
-  check if db-field is non-blank
   IF SO: create input stmt and echo db-text into it and set 'onblur' with javascript
   IF NOT: create normal input statement
- submit form:
  update table with all non-blurred input fields
