<p>Multi-Form Anti-Spam Image CAPTCHA adds a fast, accessible icon challenge — paired with honeypots and a submission speed check — to the form plugins and WordPress core screens spambots love to abuse. Users select the requested icon to verify; every challenge is generated server-side with a hashed answer so bots cannot scrape the correct option from the markup.</p>
<p>One plugin covers Gravity Forms, Contact Form 7, WPForms, WooCommerce, WordPress login, comments, and more — with full styling controls, 780+ icons, and layered bot defenses.</p>
<h4>Integrations</h4>
<ul>
<li>Gravity Forms — drag the <strong>MultiForm Image CAPTCHA</strong> field into any form</li>

<li>Elementor Pro Forms — drop <code>[pbmfasic]</code> inside an HTML widget</li>
<li>WooCommerce — toggle CAPTCHA on the Login, Registration, and classic shortcode Checkout forms (the block-based Checkout Block is not yet supported)</li>

</ul>
<h4>Spam protection</h4>

<li>Honeypot fields plus a reverse-honeypot trap that catches bots that auto-fill every field</li>
<li>Submission-speed check rejects bot-fast submissions</li>
<li>Daily cleanup of stale CAPTCHA records</li>
<li>Optional “disable for logged-in users” toggle</li>
</ul>
<h4>Styling and icons</h4>
<ul>
<li>Switch between Font Awesome icon fonts (bundled) and 780+ bundled SVG icons</li>
<li>Full styling controls: colors, borders, padding, font size, layout, alignment</li>
<li>Custom prompt text and custom error messages</li>
<li>Toggle mode hides the CAPTCHA until the user starts interacting with the form</li>
</ul>
<h4>Accessibility</h4>
<ul>
<li>Keyboard-navigable radio buttons with ARIA labels</li>
<li>Optional audio cues for screen-reader users (off by default; opt in on the General tab if you need an audio alternative)</li>
</ul>
<h4>Privacy</h4>
<p>The plugin does not call any external services and does not send data off your site. CAPTCHA records are stored in a custom table on your own database and purged automatically every 24 hours.</p>
<h4>Developer hooks</h4>
<ul>
<li><code>pbmfasic_skip_wp_login_option</code> — filter whether validation runs on WordPress login, registration, lost-password and reset-password forms</li>
<li><code>pbmfasic_skip_validation</code> — filter whether validation should be skipped for the current request</li>
<li><code>pbmfasic_force_synchronous_render</code> — return true to render the CAPTCHA inline instead of lazy-loading it via AJAX, useful when a form submits over a custom AJAX flow that needs the CAPTCHA fields present at first paint</li>
</ul>
