Rosary Presenter

A multi-user web app for leading the Rosary, novenas, and the Divine Mercy Chaplet — built for live presentation at prayer services. Live at loveandrosary.com.

What It Does

• Slide-based presentation — navigate prayer-by-prayer with leader/congregation text split on screen
• Rosary bead ring — SVG visualization tracks which bead is active in real time
• Session types — General Rosary, Memorial Rosary, Deceased Novena, Divine Mercy Chaplet
• Novena groups — link 9 daily sessions into one group with a public day-picker page
• Audio uploads — attach MP3/audio per session (up to 50 MB)
• Multi-user — role hierarchy: superadmin → admin → superuser → user
• Public profiles — each user gets a /username page with their public sessions
• Donate strip — optional PayPal / Venmo / Buy Me a Coffee link on public pages

Stack

• PHP 8 + PDO (no framework, no Composer dependencies)
• MySQL 8 / MariaDB
• Vanilla JS (no build step)
• Apache/Nginx with .htaccess rewrite rules

Setup

1. Configure database

cp config/db.example.php config/db.php
# Edit config/db.php — fill in DB_HOST, DB_NAME, DB_USER, DB_PASS
# Set BASE_URL if deploying to a subdirectory (e.g. '/rosary')

2. Create the database schema

Visit install.php in your browser once — it creates all tables (matching schema.sql, kept as the canonical structure reference) and seeds site_settings defaults, the superadmin account, and the standard prayer library. Delete install.php immediately after.

Default superadmin credentials: supadmin / supadmin — change these immediately.

schema.sql documents the current database structure; there is no separate migration-script chain to run.

3. Configure the web server

Apache — .htaccess is included. Enable mod_rewrite and set AllowOverride All.

Nginx — add to your server block:

location / {
    try_files $uri $uri/ @php;
}
location @php {
    rewrite ^/([^/]+)/([^/]+)$ /present.php?username=$1&slug=$2 last;
    rewrite ^/([^/]+)$ /profile.php?username=$1 last;
}

4. Uploads directory

chmod 755 uploads/

5. SMTP (optional)

Configure outbound email in Admin → Settings for registration confirmation and password reset emails. If left blank, the app will auto-confirm new users instead.

6. Bot protection (optional)

register.php always runs a built-in honeypot + timing trap against scripted signups — no setup needed. On top of that, you can enable Google reCAPTCHA v3: register your domain at google.com/recaptcha (choose reCAPTCHA v3), then enter the Site Key and Secret Key in Admin → Settings → Bot Protection.

7. Scheduled cleanup of unconfirmed accounts (optional)

cron/cleanup_unconfirmed.php permanently deletes accounts that are still unconfirmed 3 days after registering — useful for clearing out bot signups that get past the defenses above. It's CLI-only (refuses to run over HTTP) and is not wired up automatically; schedule it yourself as a cron job. In Hostinger's hPanel: Advanced → Cron Jobs → run daily:

php /home/<your-account>/domains/loveandrosary.com/public_html/cron/cleanup_unconfirmed.php

(Adjust the path to match your actual hosting account.) Confirmed accounts are never touched — only rows with email_confirmed = 0.

Upgrading an Existing Install

schema.sql reflects the current database structure. For a production database that predates the failed_login_attempts / locked_until login-lockout columns, run this once against it manually — it's not applied automatically since there's no migration runner against a live database:

ALTER TABLE users
    ADD COLUMN failed_login_attempts INT NOT NULL DEFAULT 0,
    ADD COLUMN locked_until DATETIME NULL;

Also needed for the photo reposition/zoom tool (photo_focal_x/photo_focal_y/photo_zoom on both sessions and novena_groups — defaults reproduce today's centered, no-zoom crop, so this is safe to run any time):

ALTER TABLE sessions
    ADD COLUMN photo_focal_x FLOAT NOT NULL DEFAULT 50,
    ADD COLUMN photo_focal_y FLOAT NOT NULL DEFAULT 50,
    ADD COLUMN photo_zoom FLOAT NOT NULL DEFAULT 1;

ALTER TABLE novena_groups
    ADD COLUMN photo_focal_x FLOAT NOT NULL DEFAULT 50,
    ADD COLUMN photo_focal_y FLOAT NOT NULL DEFAULT 50,
    ADD COLUMN photo_zoom FLOAT NOT NULL DEFAULT 1;

Deployment Checklist

• config/db.php filled in with production credentials
• install.php deleted after first run
• uploads/ is writable by the web server
• BASE_URL matches your subdirectory path (leave empty for domain root)
• Superadmin password and email changed
• SMTP configured in Admin → Settings
