Hello All,
My first post here, hope I don;t scare everyone. I’m Alan form Vancouver Canada, 2 months into php and still a newbie. Please excuse my grammar, English is not my native tongue.
my question:
I am working on developing a profile page for users of my site. one area of the site is to register an application to rent a unit in my building. part of the process of the application requires a user to write their social insurance number. I have picked up a neat little javascript utility that validate Canadian SIN with 3 input fields on a form. once the SN has been validated I then concatenate the 3 fields into one to make a complete SIN number xxx-xxx-xxx and save it into my database. all that works really well. Teh problem that I have is to explode this concatenated SIN number that was saved into my database back into the 3 input fields on the form if a user need to update their profile. I have been working at this for 3 days and have had that question floating in two other forum and nobody seems to know how I can do that. Are there any super Nija php coders in here that can help me?
here is what I have so far: NOTE: I included the whole thing in the event you are curious about different aspect of my script. Thanks a bunch for looking this over for me. I would truly appreciate feedback
