Add A Cookie Consent Banner To Shopify Store

Seems every other site has a cookie warning banner at the bottom of the page or showing somewhere informing you that by using the site you agree to their policies.

Editing your theme code to add this feature

• In the Snippets directory, Create a new section with a name whatever you want but we named it cookie-banner.liquid and add the following code:

{% assign text = "We use cookies to ensure that we give you the best experience on our website. If you continue we'll assume that you are understand this." %}
{% assign more_info = "Learn more" %}
{% assign privacy_url = "/pages/terms-conditions" %}
{% assign button_text = "Accept" %}

<div id="se-cookies-message-container">
<div id="se-cookies-message">
<div class="se-cookies-text">
{{text}} <a href="{{privacy_url}}">{{more_info}}</a>
</div>
<a href="javascript:SE_CloseCookiesWindow();" id="se-accept-cookies-checkbox">{{button_text}}</a>
</div>
</div>

<script>
function SE_setCookie (name, value, days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}
function SE_getCookie (name) {
var pair = document.cookie.match(new RegExp(name + '=([^;]+)'));
return !!pair ? pair[1] : null;
}
var cookiesName = 'cookies_accepted';
function SE_CheckCookies () {
if(!SE_getCookie(cookiesName)) {
var cookies_message = document.getElementById("se-cookies-message");
cookies_message.className += " se-cookies-message-open";
}
}
function SE_CloseCookiesWindow () {
SE_setCookie(cookiesName, true, 9999);
document.getElementById("se-cookies-message-container").removeChild(document.getElementById("se-cookies-message"));
}
document.addEventListener('DOMContentLoaded', function () {
SE_CheckCookies();
});
</script>


In the Asset directory, open theme.scss.liquid and add the following code at the very bottom of the file:
