Concise Studio

<h4>Algorithm</h4>
<ol>
<li>Plugin generates token on the backend side.</li>
<li>Plugin adds hidden field for token in each form which will use method “POST” after rendering of the page.</li>
<li>Plugin inserts token in the field after user’s interaction with site.</li>
</ol>
<h4>For developers</h4>
<p>Antispam will automatically check submissions of the regular forms but ignores all AJAX requests.<br />
If you want to change this behaviour, you can use filter <code>concise_antispam_need_to_validate_token</code>.<br />
See example:</p>
<p><em>Disable Antispam for some forms:</em></p>
<pre><code>add_filter("concise_antispam_need_to_validate_token", function($needToValidateToken) {
    if (!empty($_POST['do-not-check-antispam-token'])) {
        $needToValidateToken = false;
    }

    return $needToValidateToken;
});
</code></pre>
<p>You can also always manually call <code>\Concise\Antispam::validateTokenOrDie()</code> in your custom handler.</p>
<h3>Formidable Forms integration</h3>
<p>For proper work disable the honeypot checking in the forms</p>
