Joomla 2.5.1
CB 1.8
CB Subs 1.3.0RC1

I have a client who has several thousand existing members of their organisation (labour union) - at present they have no website or electronic communications - approximately 10% have known email addresses.

We have built the website and are now preparing the registration process for them.

On registration the client would like to validate each registration (before getting to the email verification process) by asking the members to enter their First Name, Last Name and Union membership No and having that data checked against the expected values for that member. If the data matches then the member proceeds with the rest of the registration - if not then they're binned out of the process and given a contact form to get their data checked.

The first name, last name, membership no data is currently just in an excel spreadhsheet.

What is your recommendation on the best way to acheive this?

kind regards

Mike

You have specified 'within the Joomla Database' - no problem with that but wondered if this would also work if the DB was outside the Joomla DB? Just thinking of another application.

Some guidance required here from an absolute beginner with MySQL.

I have created a new table in the Joomla Database and uploaded the existing membership data. The new table is called `u76wz_union_membership', with column headings of 'ID', 'union_first', 'union_last' and 'union_member_no'. I have installed CB Database Lookup, enabled it and am now trying to create the query.

The workflow that I envisage is that the new user will complete their First name, Last Name and then at the DB lookup field they will be asked to input their membership no. The DB query will then check that the value entered matches 'union_member_no' and 'union_last' from `u76wz_union_membership'.

That's where I get a little stuck - so far my query reads:

SELECT * FROM `u76wz_union_membership` WHERE `union_member_no`= '[value]' AND `union_last` = '0'

Clearly, "`union_last` = '0'" is inadequate as it needs to reference the value in the 'Last_name' field that has been entered by the member on registration. I imagine that with the answer to that I will also be able to complete the SQL query update and SQL query rollback update.

Now that brings me to my next question, with the answer 'yes', the data matches and the query is successful, how do I use that result to allow or disallow the registration process to continue?

Many thanks

Mike
