Using Checkbox to select staffIDs (data) to display on a page

I have developed a PHP page with data from different tables (MySQL). The page fit on an A4 paper. The page contains staff personal data. I can display staff personal data of a single staff, at a time. What I want is to create another page with staffid (or staff name) and a checkbox in front of a staffid. The aim is when I check, say four staffids and click a button then I should get four different pages for each staff (each page with different data). That’s where I have a problem. Help will be appreciated
