我有这个代码:

echo "debug 12.1";
$stmmt21 = $conn->prepare("INSERT INTO Together (OneT, TwoT) VALUES (?, ?)");
$UserOne = "netsgets";
$UserTwo = "netsgets2";
$stmmt21->bind_param('ss', $UserOne, $UserTwo);
$UserOne = "netsgets";
$UserTwo = "netsgets2";
$stmmt21->execute();
$stmmt21->store_result();

当我运行它时，我收到此错误:

Call to a member function bind_param() on boolean

Answer 1

这是因为您的声明$conn->prepare(...导致某种错误，肯定会分配false至$stmmt21 .所以当你调用bind_param(...在 $stmmt21 ，解析器会在 boolean 上提示它不允许.

解决方案:请检查为什么是 $conn->prepare()给你错误。是由于您的连接字符串，还是 INSERT您指定的查询。
