Part 16(D) - Join User

Check Space

It is the time to check the space that it is available or not. The new user that we will join a parent user and the side that we select, at that position, no user should available already. For this, we will create a function that will return true or false for space. First, we will create a table tree` to store all the tree structure information.



Function side_check

function side_check($email,$side){
	global $con;
	
	$query =mysqli_query($con,"select * from tree where userid='$email'");
	$result = mysqli_fetch_array($query);
	$side_value = $result[$side];
	if($side_value==''){
		return true;
	}
	else{
		return false;
	}
}
