Test your PHP registration, login and content management system on a live server, verify the email activation flow, troubleshoot credentials and path configurations, and ensure mail delivery before going live.

Learn a PHP login flow that validates the username exists, checks activation, verifies the password hash, and sets a session or remember-me cookie.

Fetch a user’s data, verify the user is active, authenticate the password with password verify against the stored hash, and start a session before redirecting to content.

Authenticate users via a server-side session to access personalized content and enforce redirects that block unauthenticated access in a PHP registration, login, and content management system.

Learn to persist login status using a remember me checkbox by setting a username cookie when checked, syncing it with the session, and updating navigation to show logout.

Unset the session variable to log out, destroy the stay-logged-in cookie by expiring it in the past, and redirect users to the home page.

Explore a secure two-step password reset flow using email verification, a reset link with username and validation code, and hashing the new password before updating the database.

Verifies the entered username against the database with count_field_value, then emails a reset password process containing a validation code, using post request handling, session data, and get parameters.

Implement a new password form within a two-step reset flow, validating user and code via GET parameters, hashing the new password, and updating the database.

Submit a new password securely by validating post requests, hashing the password with bcrypt, and updating the database via prepared statements while checking password confirmation.

Explore how a content management system manages access with users, groups, and pages, using one-to-many and many-to-many relationships and the required users, groups, pages, and user_group_link tables.

Set up the database schema for a php registration system by creating groups, pages, and user group link tables, with primary keys, foreign keys, and dropdown-driven group selections.

Set up the admin page for a php registration, login, and content management system to manage users, groups, and pages, using a root directory variable for absolute and relative paths.

Make admin navigation absolute, implement tabbed sections for users, groups, and pages, and enable data listing and insertion with database-ready forms and sorting by username.

Add group functionality by reading form data from post, validating group name, inserting name and description into the groups table via a prepared statement, and redirecting back to admin page.

Add pages and groups via admin page and pages tab. Validate inputs, ensure the group id exists, insert pages with name, description, url, and group id, preserving data on errors.

Dynamically populate a group select from the database by replacing group IDs with group names, querying the groups table, ordering by name, and rendering options in the admin pages.

Learn to assign users to groups in a PHP CMS by adding a user-to-group link, building a manage users page, and using get parameters to insert into the user_group_link table.

Enhance the admin manage users page by listing group members, showing user and page counts, and refining queries to fetch user details for admin group management.

Link users, groups, and pages to control page access by group membership, then render a user-specific content table on the my content page using a joined SQL query.
