Passing ID and showing form dependent on ID

[s_ainley87]

Hello,

 

I am currently trying to work something out in my head, I wanting to have a form that can add a user to a db and also edit the users. I want to use the same form for both tasks, but on the edit form on have the editable fields enabled. I am trying to work out the best way to ascertain whether the user is adding or editing a user. I thought about creating a function the creates a session called edit and then check for that session on my form page and if it matches run some javascript to disable the uneditable form fields. Or would a better way to do have so that if the user exists in the database it immediately goes to edit page with the disabled fields.

 

Basically what I am asking is, it best to use a session or pass the user id, so it checks if it exists?

 

Thanks

You can use any method as long as a flag is set to identify the mode you are in.

Personally I would forget about using a session an use URL parameters ie:

 

form.php?action=create

form.php?action=edit&userId=5

 

You can use the action value and userId value within hidden fields in the form to retain the mode you are in an the user record you are editing
