Hi everyone, I have a web application developed using php. I want to add a new feature in it. When the user searches for some book details, all the book details are displayed. Now when the user clicks on a book name in the search results, He will be redirected to another webpage , where user can Update details of the book choosen from the previous page. Now my question is, when user links on a specific book name How can I store it in a variable , so that it will be used to query database?
