This is called a captive portal, and setting one up requires hardware/software configuration. How you do it will depend on what kind of wifi system you are using.
To display a webpage when users connect to a Wi-Fi network, set up a captive portal. Choose a platform like pfSense or use a cloud-based service, configure the portal, set up DNS redirection, and enable authentication or agreement before granting internet access. Tutorials specific to your chosen platform can guide you through the setup.
