PHP mysql query not giving extra output

I am a php programmer.When a page gets loaded some records are shown from a table(in a tabular format on the php page) , on the page there are html submit buttons corresponding to whose post some other values are to be shown.

The problem is, the other values are shown along with the values which are shown when the开发者_StackOverflow中文版 page first loads. I want to show fresh set of values , without the default values which are shown when the page first loads.

It has to be mentioned that the default page load values which are fetched from the table is not done corresponding to any isset($_POST) unlike the other fresh values.

can you help me out?

Try using some random numbers in the query or other patterns in the query so that you get records afresh than getting the same records every time you visit the page.

Hope my understanding is right.
