Cookie block

Hi @geoffmartyn

What hook are you using with this?

Hi Fernando,

Sorry, I’ve tried to add it via wp_head, but overall I’m just trying to block a single cookie so I can see how it works and then I can go from there.

function analytics_snippet() {
  if ( is_allowed_cookie( '_ga' ) {
?>
     
     <script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-xxxxxxxx-x', 'auto');
  ga('send', 'pageview');

</script>
<?php
  }
}

add_action('wp_head','analytics_snippet');

Hi @geoffmartyn,

One of your IF statements is missing a bracket.

It should be:

if ( is_allowed_cookie( '_ga' ) ) {

Hi @amooreto,

You are a star! Thank you – I knew it was something really simple!

That’s in now, but I still can’t get it to delete the cookie when I change the preference in the cookie popup.

In the examples here:

“…assuming you registered an analytics consent and _ga as one of the cookies used…”, the line from the my_google_opt_out function:

if ( ! has_consent( 'analytics' ) || ! is_allowed_cookie( '_ga' ) ) {

…doesn’t seem to do anything.

The page also mentions that it assumes I have ‘registered an analytics consent’ but does this refer to a tab in the cookies settings page or a category name of cookie?

Is there an example online anywhere of an implementation of this plugin that will actually remove and then re-set Google Analytics cookies (for example) once it’s approved again? I’d just love to see if it’s possible, or if I’m barking up the wrong tree.

Thank you once again!

Geoff

Hi @geoffmartyn,

The plugin will prevent the cookie from being created but it will not delete the cookie. Not in the current version.

I’m preparing a release with this feature. But rest assured that even if the _ga cookie is still there, if you are not accepting the _ga cookie or the consent it will not send analytical data to Google.

Hi, I am trying to understand how blocking/enabling cookies works. This thread has been helpful, I just want to put it in plain language what the steps are. Please let me know if they are correct.

1. Identify Cookies used on the website
2. Register cookies in the plugin under Cookies Tab
2a. Add Category name ‘analytics’
2b. identify cookies used – ‘_ga, _gid, _gat’
3. Add the code below in the functions.php file

add_action( 'wp_head', 'my_google_opt_out' );
function my_google_opt_out() {
  if ( ! has_consent( 'analytics' ) || ! is_allowed_cookie( '_ga' ) ) {
    ?>
    <script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-xxxxxxxxx-x', 'auto');
  ga('send', 'pageview');

</script>
    <?php
  }
}

But what does this do. If the cookies are off, then this function will not make them available and then google will not track? Do we need to create analytics consent too?

What about _gid and _gat? Does a separate helper function for each need to be added?

What if we have Facebook Pixel on the site? Is a new category need to be created and a new helper function in function.php file has to be added?

Thank you for your help, I know it is basic questions, but I just want to understand how to properly implement it.

I can’t legally tell you what types of consent you need. There are infinite cases out there. You can have privacy policy only, you can have analytics consent, you can have none, it’s up to you to decide how to structure your stuff.

GA sets, in general, 3 cookies. You only need to check for one of them. In this case, _ga.

This will turn GA off entirely. You can do that or you can google how to make your google analytics data anonymous. That way there’s no PII involved and should be OK. Again, I’m not a lawyer. You should talk to one.

For FB pixel it all depends on how you are adding it. If it is the same way, the same thing would apply, but with a different cookie name or consent type.

Thank you, I understand legally you cannot advise, we are talking to some regarding that. I just wanted to make sure the code to use and how to use it is the right way.

So if we do not require a separate consent for google analytics, I would use the code like this in the if section?

function my_google_opt_out() {
  if ( is_allowed_cookie( '_ga' ) ) {
....the rest code under here as above

Can I use something like this:

function my_google_opt_out() {
  if ( is_allowed_cookie( '_ga', '_gid' ) ) {
....the rest code under here as above

Thank you. I will google how to make google analytics data anonymous too. Good suggestion.

ALSO, currently we have the google tracking code in header.php file. Do I remove it from there when adding helper function in functions.php file?

You can’t use more than one cookie name with that function.

Yes. Remove the code from the header.php file.

This might be a dumb question @fclaussen. So we register a cookie then we have to add the lines of code? Thanks

Yep. Sadly there’s no way for me to block cookies for users. So yea, extra code is needed. ??

Thank you, so if we need to remove Facebook Pixel cookie, I would register it in the plugin and then add a helper function next to google analytics function with the new name and whatever FB pixel cookie is named. Something like that:

function my_facebook_opt_out() {
  if ( is_allowed_cookie( '_fbq' ) ) {
....the rest code under here 

Yep

Thank you for answering all my silly question @fclaussen. It makes more sense now.
