This is a WordPress project about bill payments. This site has been developed by someone else. This website provides various types of datasheet access for its users to download. The client wants to know who downloads which datasheet so they give me the credentials and I customize their site to do this functionality. Now if someone wants to download any datasheet and clicks on the download button the site shows a popup to provide some details then he/she will be able to download the specific datasheet. Clients bound me to use specific forms and conditional logic. Now everything is working fine.
