I manage to get it to delete each row but it seems to do it each page refresh.

Thats because you have no if statement to tell it otherwise. 

 

Each time the page loads it will just fire 

$order = mysql_query("DELETE FROM booking  WHERE bookingid ='$eventid' LIMIT 1");

 

Unless you have a stament which says - if something then delete row

 

e.g

 

if ($delete = '1' ){

$order = mysql_query("DELETE FROM booking  WHERE bookingid ='$eventid' LIMIT 1");

}

The delete sql statement does not execute according your code above:

 

What you want to say whit that one?

if ($delete = '1' ){
$order = mysql_query("DELETE FROM booking  WHERE bookingid ='$eventid' LIMIT 1");
}

If the form is submitted delete selected row.

This is the form section
