Primary Key? How to auto generate for regsitration?

[nwatkin03]

I'm using DW8, i'm creating a registration form and I placed a hidden field in it called res_id. I want this to auto generate a unique id when people register.. how is this possible?

mysql with php

Generally you would generate the key in the database and then call it back
to subsequent pages if you needed it.

Paul is right with that,

If you open up your MySQL Command line client and alter the table with a statement like:

ALTER TABLE myTable
ADD PRIMARY KEY (columnName);

Where myTable and columnName are the name of the table and column you want to edit.

That should at least set the column to the primary key.

If you want to set the primary key to auto generate a unique id follow this up with another command like:

ALTER TABLE myTable
MODIFY columnName int auto_increment;

Use the command:

describe myTable;

to see the structure of the table and to check that everything has worked ok...

Hope this helps.
