MySQL DELETE语句无法识别PHP $ id变量中的空号

我正在尝试在数据库中允许雇员的删除。我已将查询字符串存储到名为$ id的变量中。当我运行SQL DELETE语句时,它回显了,但没有回显或识别出我实例化的$ id变量。有什么想法吗?

PHP

//QUERY STRING
"<td><a href='delete.php?id=" . $row['empid']  . "'>Delete</a></td>" .

//ID VARIABLE
 $id = (isset($REQUEST['id']) ? $_REQUEST['id'] : '');

SQL

//SQL STATEMENT
$sql = "DELETE FROM employees WHERE empid= '" . $id . "';";

//WHAT ECHOS OUT IS BELOW
echo($sql);

//RUN SQL Command
mysqli_query($connect,$sql) or die(mysql_error());
print("User " . $id . " deleted from the database.");
print("Return to <a href='index.php'>Return To Main Page</a>");

从员工那里删除empid ='';

当我单击index.php中的delete时,我尝试删除的员工仍然在那里。

您需要更改此行

$id = (isset($REQUEST['id']) ? $_REQUEST['id'] : '');

$id = (isset($_REQUEST['id']) ? $_REQUEST['id'] : '');
