PHP Hook Reference

English version coming soon

This page has not been translated to English yet. Please refer to the Japanese version for full details.

Form Plant exposes WordPress action / filter hooks at almost every stage of form processing — submission lifecycle, email sending, redirects, file uploads, fields, and form settings. Add a hook in your functions.php to extend behavior without modifying the plugin.

Validation hooks ( fplant_validate_* / fplant_validation_message_* ) have their own page: Validation Hooks (PHP).

Quick reference (selected)​
