Block cookies until user acceptance

Hello, after talking with other plugins as GDPR Cookie Compliance (CCPA ready) they told me that you need to include in such way any hook for disabling the cookies.

So other cookie plugins and developers can block or allow (by previous user acceptance) the use of cookies.

You can please check the other thread here:

Thank you.

Please don’t mark this issue as resolved until is resolved.

Is true that I have contacted your support team but the issues are still happening and no workaround has being issued.

So this ticket is not resolved.

Thank you.

Unfortunately current implementation does not have any easy way to address this issue, but here is two work arounds:

1. You can patch the plugin (make change in the plugin). Unfortunately changes will be lost if you will update the plugin.

To patch the plugin
1. Open omnisend-connect/omnisend-woocommerce-hooks.php.
2. Scroll to line 215, you should see the following if statement:
if (OmnisendHelper::isWooCommercePluginActivated() && OmnisendHelper::checkWpWcCompatibility() ) {
3. Add additional check accordingly to your needs, e.g. :
if (OmnisendHelper::isWooCommercePluginActivated() && OmnisendHelper::checkWpWcCompatibility() && isset( $_COOKIE[ 'my_cookie' ] ) ) {

-OR-

2. You can add a following function to your functions.php in your theme/child theme:

function load_omnisend_with_consent( $value, $option ) {
	if ( ! isset( $_COOKIE[ 'my_cookie' ] ) ) {
		return null;
	}

	return $value;
}
add_filter( 'option_omnisend_account_id', 'load_omnisend_with_consent', 10, 2 );

Ideally a ‘wp_footer’ action should be not be set up as anonymous action, so other plugins would have a chance to remove / modify the behaviour.

NOTE: Your site user will have to reload the page (if its not done automatically after accepting cookies) for Omnisend JS snippet to be loaded.

Hello @mb00, thank you for your idea.

But this patch as you said will not be compatible with future plugin updates. So I think this is a MUST for the plugin creator to implement ASAP.

Your approach is valid and a good one, but I prefer something like the Facebook plugin does. They use a class property with a filter function and if that value is true, they inject and enable the plugin and cookies.

/**
* Determines whether the Pixel should be enabled.
*
* @since 2.2.0
*
* @return bool
*/
private function is_pixel_enabled() {

  if ( null === $this->is_pixel_enabled ) {

    /**
    * Filters whether the Pixel should be enabled.
    *
    * @param bool $enabled default true
    */
    $this->is_pixel_enabled = (bool) apply_filters('facebook_for_woocommerce_integration_pixel_enabled', true );
  }

  return $this->is_pixel_enabled;
}

With this approach we can use something like:

add_filter('facebook_for_woocommerce_integration_pixel_enabled', 'our_function', 20);

If this plugin is public and on GitHub or similar, I don’t mind to take a look and maybe propose a PR.

The full implementation on the Facebook pixel plugin can be seen here:

I’ve proposed 2 options, first option requires patching, the second does not. Adding #2 solution to your functions.php will allow you to update the plugin.

Sorry @mb00 I do not pay enough attention on the second method.

Your solution worked. I post here the snippet for someone needing this to work with https://www.ads-software.com/plugins/gdpr-cookie-compliance/

/* disable omnisend on gdpr_cookie plugin */
function load_omnisend_with_consent( $value, $option ) {
    if (function_exists('gdpr_cookie_is_accepted')) :
        if (!gdpr_cookie_is_accepted('thirdparty')) :
            return null;
        endif;
    endif;

    return $value;
}
add_filter( 'option_omnisend_account_id', 'load_omnisend_with_consent', 10, 2 );

/* force reload on gpdr_cookie accept */
add_action('gdpr_force_reload', '__return_true');
