How can I pass data from one page to another?

Question

So regarding my question I have two pages. Page1.php to save customer sale information and Page2.php to display the sales(Page2 is connected to a monitor in our office no user interaction, no keyboard, no mouse).

.

In Page1 the users can save information about customer sales. For example product name. The users user is always connected to the sale. After submitting the sale, I want it to show up on Page2., and says something like: User Demitri just sold a PS4 .

What have I tried so far :

Now when the user register sale, it saves into a MySQL table, and the Page2. automatically refreshes( <meta http-equiv="refresh" content="10"/> ) the page every 10 second to see if any new record has been added to the table. If a new record is there, it will display the user and the product that was sold on the page for 30 seconds, example: User Demitri just sold a PS4 , and then it will remove the record from the table, and then refresh the page again to see if any new record has been added to the table.

What do I want to accomplish:

I want a sort of system that can be used to pass data from Page1. to Page2, without needed any user interaction on Page2, and don't need to have a auto refresh script that runs every 10 second. This also looks bad because every time it refreshes, the website will sort of blink.

This is a very cumbersome process to do it, there must be some other way?

Answer 1

我会推荐使用 dB 来存储数据，需要该数据的页面可以查询数据.. 也许使用 ajax、fetch 和一些 setinterval 函数

Answer 2

1. Use ajax, so you don't have to refresh the page every 10 seconds.
2. Use websockets. Once you notice a new sale, you just push it and then your connected page can display it. This would be the best way i think.
