So what i want to do is when vendor post candidate_details by using form ..i want to store that user_id

(where user_type_id=1)

in candidates_details table automatically..

Can anyone help me..Thanks in advance..

Let me help you out by giving a pictorial example. Assume you have two tables users and candidate_details. In users you are keeping record of all the registered users along with their types. In Candidate Details you are keeping their profile data. You create another table where you keep user types Be it vendor, contractor, supplier etc.

Now when you create your form to post data in your admin panel or which ever interface you have. Just create a dropdown for user_types, get the type id and add the user. With the type id in your users table you can easily query which type of user that is.

Now for saving that user's profile information in candidate_details table you only have to provide user_id. So creating one more table will normalize your db schema and saves a lot of hustle in your query building.
