Berestov Element Scheduler

Berestov Element Scheduler replaces the inner HTML of selected frontend elements by schedule.

It can match a parent element by class or ID and replace everything inside that parent with the value you define.

Supported schedule groups:

• Weekdays
• Odd and even month days
• Odd and even ISO weeks
• Persistent replacement

Features:

• Unlimited rules
• Search by class or ID
• Class mode works across all matched elements
• Multiple different rules per schedule slot
• Duplicate prevention inside the same slot
• Server-side, JavaScript, or Auto replacement mode
• UTC offset based switching
• Drag and drop schedule UI
• Translation-ready admin UI

Use cases:

• Rotate phone numbers
• Schedule banners
• Switch promo blocks
• Replace HTML snippets by schedule

Days without a rule stay unchanged.

Security

• Capability checks and nonce validation for all administrative actions.
• Strict sanitization and option whitelisting for all saved settings.
• Only explicitly allowed configuration fields are accepted.
• HTML output follows WordPress capability rules (unfiltered_html).
• The plugin does not contact external services or third-party APIs.
