Description

Validation Muse for Contact Form 7 lets you override the default error copy that Contact Form 7 displays. Enable the plugin per form, then supply custom text for required notices and invalid email, URL, telephone, number, range, and date validation. Messages are stored in post meta so they stay with the form when you export/import.

Features:

  • Customize “required field” messages per field
  • Customize “invalid format” messages for email, URL, phone, number, range, and date fields
  • Enable/disable custom validation per form
  • Messages stored in post meta for easy export/import
  • Fully translatable with POT file included
  • Accessible admin interface with ARIA labels
  1. Upload the validation-muse-for-contact-form-7 folder to /wp-content/plugins/, or install it from the WordPress admin under Plugins Add New.
  2. Activate the plugin through the Plugins screen.
  3. Open any Contact Form 7 form, switch to the Custom Validation panel, enable the feature, and save your messages.
Does this plugin require Contact Form 7?

Yes. Contact Form 7 must be installed and active. The plugin will display an admin notice and automatically deactivate itself if Contact Form 7 is missing.

Which field types support custom invalid messages?

Email, URL, telephone, number (including range), and date tags can display custom invalid-format text. Any required field can have a custom “required” message.

Where are the messages stored?

Messages are saved in each form’s post meta. They are included in Contact Form 7 exports, so migrating a form will move the messages with it.

Can I use HTML in validation messages?

Yes, basic HTML is allowed and sanitized using wp_kses_post().
