I need a PHP developer for my WordPress site to make some coding amendments

I am in the middle of migrating my old Wordpress site to a new theme. Nearly all of the pages are completing, but there are some coding changes that are required.

Here is my list of tasks that need completing.


1. Customer Registration

Currently, I've installed the Ultimate Member plugin so I can create a custom registration form.

What I would like, is when the user registers, that we allocate the next account number to them. That account number would then be included in the confirmation email that we send to the customer and also stored with the user registration data.

The account number is simply the next number. The current account number is 30122056, but this changes every day. It will be a simple matter of taking the account number and incrementing it by 1 every time.

I've checked the database and found that the current user id is held in the options table, so using the code below will give you the next account number.

$current_userid = get_option('current_userid');
$current_userid = $current_userid + 1;
update_option('current_userid', $current_userid);


In addition, when the registration email is sent, our current system creates a text file with all of the customer information and stores it in a "registrations" folder on the server, we would need the same replicating. I've attached a sample file.


2. Show Data

The new website has a custom developed plugin called "Show Data". The plugin allows certain customers to view their orders that have been placed along with any updates. Once the customer logs in, the plugin checks to see if the account number exists the "tblportalaccess" table. If it does, the icon is displayed. I need help in displaying the icon once the customer has logged in.

Thanks
