Usage

Shortcode

Add this shortcode to any page or post:

[wordcamp_certificate]

You can also override event details inline:

[wordcamp_certificate event_name="WordCamp Manila 2025" event_date="July 12, 2025"]

Gutenberg Block

1. Open the Block Editor on any page or post.
2. Search for "WordCamp Certificate Form" in the block inserter.
3. Add the block — it renders a live preview in the editor.
4. Use the Inspector Controls (right sidebar) to override the event name and date per-page.

Direct URL

Once a certificate is generated, it lives at a permanent URL:

https://yoursite.com/?wcc_cert=1&token=UNIQUE_TOKEN

This URL can be bookmarked, shared, or re-printed at any time.

Database

On activation the plugin creates one custom table:

CREATE TABLE wp_wordcamp_certificates (
  id           BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
  full_name    VARCHAR(255) NOT NULL,
  email        VARCHAR(255) NOT NULL,
  issued_at    DATETIME DEFAULT CURRENT_TIMESTAMP,
  cert_token   VARCHAR(64) NOT NULL,
  PRIMARY KEY  (id),
  UNIQUE KEY   cert_token (cert_token),
  KEY          email (email)
);

The table is created with dbDelta() so it is safe to re-activate without data loss.

Security

• All AJAX requests are verified with wp_create_nonce / check_ajax_referer
• User input is sanitized with sanitize_text_field and sanitize_email before processing or storage
• All database queries use $wpdb->prepare() — no raw interpolated SQL
• Certificate tokens are generated with wp_generate_password( 32, false ) (cryptographically random)
• The certificate template runs outside the WordPress theme loop but does not expose any credentials
