make a replica of players table as players_backup and insert the data first to backup table and once you get the num rows after inserting is greater than zero that means the data has been inserted. after this you can delete the data from the players tables. Simple.
i am assuming that players and players_bkp have same schemas.
if (isset($_GET['id']) && is_numeric($_GET['id']))
{
// get the 'id' variable from the URL
$id = $_GET['id'];
$sql = "insert into players_bkp select * FROM players WHERE id = ? LIMIT 1";
$stmt = $mysqli->prepare($sql);
$rc = $stmt->bind_param('i',$id);
$rc = $stmt->execute();
$tid = $stmt->insert_id;
$stmt->close();
if($tid > 0){ //that means record is inserted and you can actually delete the record from your players table
// delete record from database
if ($stmt = $mysqli->prepare("DELETE FROM players WHERE id = ? LIMIT 1"))
{
$stmt->bind_param("i",$id);
$stmt->execute();
$stmt->close();
}
else
{
echo "ERROR: could not prepare SQL statement.";
}
$mysqli->close();
// redirect user after delete is successful
header("Location: view.php");
}
}
else
// if the 'id' variable isn't set, redirect the user
{
header("Location: view.php");
}
