[Solved] Stay on same page after login shopify product page

- Open the file blurry-coupon.liquid

- On line 10 beginning with : <br><p> Blurry? <a href="/account/regist...

- Replace the entire line with the below code and click Save

<br><p> Blurry? <a href="/account/register?url={{ theme_role | theme_url }}">{{ 'customer.register.title' | t }}</a>/<a href="/account/login?url={{ theme_role | theme_url }}">{{ 'customer.login.sign_in' | t }}</a> to see the coupon <p>

- Open the file customers/login.liquid

- Locate the line (number 9) {% form 'customer_login', novalidate: 'novalidate' %}

- Add this code just below it

<input id="urlRedirect" type="hidden" name="checkout_url" value="/collections/all" />

Then at the botton of the file, add this code

<script>
jQuery( document ).ready(function( $ ) {
document.getElementById("urlRedirect").value=getQueryVariable("url");
});
function getQueryVariable(variable)
{
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
if(pair[0] == variable){return pair[1];}
}
return("/collections/all");
}
</script>
