Validation Muse lets you write your own validation rules and error messages for every Contact Form 7 field — directly in the form editor, per form, per field. No code, no global settings page, no JavaScript hacks.
Most CF7 validation plugins broke when Contact Form 7 6.x introduced Schema-based Validation (SWV). Validation Muse runs its filters at priority 20 (after CF7 core) and uses Reflection to replace SWV error text on already-invalidated fields, so your custom copy actually shows up — even on the new validation engine.
<h4>Why Validation Muse</h4>
<ul>
<li>CF7 6.x SWV compatible — works with the new Schema-based Validation engine, not just legacy hooks.</li>
<li>Custom Regex & Length Rules — define custom regular expression patterns, min length, and max length rules per field with their own error messages.</li>
<li>Conditional “Required-If” Rules — make fields required only when a companion field is filled/checked.</li>
<li>Client-Side SWV Integration — standard validation rules (required, email, length) are injected into CF7’s native SWV engine for instant frontend feedback with full accessibility (A11y) support.</li>
<li>Rule Sets Import/Export & Templates — export/import validation rules as JSON, copy them from other forms, and bulk apply global templates.</li>
<li>Placeholder Tokens — use <code>{field_label}</code>, <code>{min}</code>, and <code>{max}</code> in validation messages to generate dynamic texts.</li>
<li>Per-form, per-field — each form keeps its own messages; no global override.</li>
<li>Stored in post meta — messages live with the form, compatible with CF7 form duplication and third-party CF7 import/export plugins.</li>
<li>Multilingual via WPML, Polylang & Flavor — translates rules using standard WPML/Polylang hooks, and features language tabs + one-click AI Translate when Flavor is active.</li>
<li>Developer-friendly — extensibility hooks <code>vmcf7_loaded</code> and <code>vmcf7_validation_tag_types</code> let you add custom field types.</li>
<li>Lightweight — no admin bloat, no tracking, no upsells.</li>
</ul>
<h4>Supported field types</h4>
<ul>
<li>Required-field messages: any required tag (<code>text</code>, <code>textarea</code>, <code>select</code>, <code>checkbox</code>, <code>radio</code>, <code>file</code>, etc.).</li>
<li>Invalid-format messages: <code>email</code>, <code>url</code>, <code>tel</code>, <code>number</code> (including <code>range</code>), <code>date</code>, and <code>time</code> fields.</li>
<li>Custom error messages on validation failure: <code>file</code> (size/type checks), <code>acceptance</code> (unchecked/unaccepted state), and <code>quiz</code> (incorrect answer).</li>
<li>HTML inside messages is allowed and sanitized through <code>wp_kses_post()</code>.</li>
<li>Custom Regex and Min/Max Length rules support all input fields (excluding acceptance and quiz).</li>
</ul>
<h4>Translations</h4>
The plugin ships with a <code>.pot</code> file and is already translated into Dutch, German, Russian, Spanish (Chile/Spain). <a href="https://translate.wordpress.org/projects/wp-plugins/validation-muse-for-contact-form-7" rel="nofollow ugc">Help translate it into your language.</a>
