I am developing a fairly simple tool, it is for a Call Center works in the following way.
It is basically a "Ranking" of best sellers, by means of a form the sales are entered into a database and on the page informe.php this table of the query the sales data are grouped by sellers and and ordered by totals.
The problem is that when entering a sale you should go to the report.php window and reload the page to be able to see the new sale. what I want to do is to be able to enter the new sale and automatically appear in the window of reporte.php and entered the sale without having to update the page.
