Membership, a new project from Chester-le-Street ASC aims to make swimming club management simpler. It is available under the Apache open-source license, so you are free to use our code in any way possible.

This software is continuously developed in accordance with the business and operational needs to Chester-le-Street ASC. We use a version of this software for our day-to-day club management, though it is further specialised to our needs and legal obligations, such as GDPR compliance.

If you install this application on your own server, you must set up the SQL database tables yourself. You will need to modify the config-template.php file to connect to your database and rename it config.php. A Schema is provided for setting up your Database, though you will need to manually create an admin, where the password is a salted hash (preferrerably BCrypt). Use the PHP password_hash() functions for this.

Chester-le-Street ASC accept no liability for any issues, including all legal issues, with this software. As mentioned, we use a slightly different version of this software which is better suited to deployment environments.


Automatic Member Management

The application is built on a database of club members. Members are assigned to squads and parents can link swimmers to their account. This allows us to automatically calculate monthly fees and other things.

Online Gala Entries

Galas are added to the system by admins. Parents can enter their children into swims by selecting their name, gala and swims. This cuts down on duplicated data from existing arrangements. Parents recieve emails detailing their entries.

Online Attendance Records

Attendance records are online, facilitating automatic attendance calculation. Squads are managed online and swimmer moves between squads can be scheduled in the system.


Notify is our E-Mail and SMS mailing list solution. Administrators can send emails to selected groups of parents for each squad. The system is GDPR compliant and users can opt in or out of receiving emails at any time.

Direct Debit Payments

This application has been integrated with GoCardless and their APIs to allow Chester-le-Street ASC to bill members by Direct Debit. The GoCardless client library which is included in this software is copyright of GoCardless.

Online Membership Renewal and Registration

We're able to walk parents through the annual renewal process, including checking their details, updating details for their swimmers such as medical information and photography permissions as well as agreeing to the club code of conduct and terms and conditions. At the end of the process, we charge users their ASA Fees by Direct Debit.

Legal Notices for Third Party Libraries

This application contains third party client libraries. These are managed via Composer. They will come with the application, so we recommend that you do not update them via composer yourself, as this may cause issues.
