Redirecting a user to a particular page after checking the data entered is matching the data present in the database

I want to redirect a user to a particular page if he enters a data that is present in the database.

For example:
In my database their are 2 fields one is for “email” & second one is for “link”.
Now I want if a user enter the “email” present in the database then he is redirected to the “link” set in that database.

As per set in my database, I want if a user enter “abcd@gmail.com” as email then he is redirected to “www.google.com” as per set in database.

Check My Database:

Check My Page Code:

Is the ‘link’ field a URL?

Was not earlier, but I edited it some time ago but still no outputs.

Check:

I mean to ask if the actual field itself a URL key value? click on the elipses on the right side of the field header, then click manage field, and see what the Field Type is.

Yes, it’s a URL field.

Can anyone help me with this or no?
