Hi;I have a product page , written by a PHP programmer and it connects to MYSQL DB.There is only one "admin login" to add new products but there are many products to be added. So as multiple users try to add new products , they try to login with the same username and password. Although the message "The new product is added successfully" is seen, no one see the product that he/she added.However if only one person logs in , the product is added and seen in the list.What should i do?Is it something to be done with PHP codes or Mysql?By the way i dont know about PHP and Mysql , but i wanna know.Thanks for reading this long , boring question. More than thanks if you reply.
