I have 2 buttons "removeD" and "updateRecord"(by id) and I have written same ajax for them as follows:
$.ajax({
    url: 'DB/tableDisplay.php',
    type: 'POST',
    data: 'id='+uid,
    dataType: 'html'
})
But in tableDisplay.php I want to have different functionality for both the buttons.How to check the id of the button clicked in php? 
I've tried using :
if(isset($_POST['removeD'])){
}else{
}
But this is not working.
