I'm trying to fetch data from URL to show product seller name in the frontend, I used one seller name like abc&xyz, but when I'm trying to display data on fancy box data is not visible.
Here is my URL looks like this, seller_info.php?seller_name=abc&xyz.
here you can see data is not visible of this abc&xyz variable:

So my question is how to use & between name and display data using URL.
I hope I tried to explain to you my query.
&is used as a field separator in your url query.You can use
%26which is your&encoded to be used in an uri.You can read more about it on MDN
