我在 NotORM 代码中遇到问题。
这段代码运行良好：
$select = $db->pspaym->select("COUNT(*)")->where("F4","$textdate")->fetch();
$count = count($select);
但是这里的代码不起作用：
$select = $db->pssale->select("COUNT(*)")->where("F8","$textdate")->fetch();
$count = count($select);
此代码有一条错误消息说：
“试图获得非对象的属性”
无法解决此问题。
所有变量都不为空。
谢谢。
if you want to count lines in a table, simply use:
$select = $db->pspaym->where("F4","$textdate");
$count = count($select);
The problem comes from your combination of fetch() and count() methods. Because of the ending fetch call, $select doesn't contain a Table object, but a Record object.
So count($select) will count the number of columns in your record. Normally, it should always returns 1 (because one field in the returned record).
For your information, if you want to be uselessly explicit, you may do something like this.
$record = $db->pspaym("F4","$textdate")->select("COUNT(*) AS c")->fetch();
$count = $record['c'];
But, that's the long way.
