推荐答案

嗨
要停止

Hi
To stop

Notice: Undefined index: myusername in C:\xampp\htdocs\admin\checklogin.php on line 20<br />
<br />
Notice: Undefined index: mypassword in C:\xampp\htdocs\admin\checklogin.php on line 21

，请不要将变量定义为"，在其中放置诸如"test"之类的内容或诸如SHA1校验和之类的长字符串.

至于Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\admin\checklogin.php on line 32，请摆脱count函数，并插入以下代码:

Don''t define the variables as "" put something like "test" or some long string like a SHA1 checksum in there.

As for Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\admin\checklogin.php on line 32 , Get rid of the count function and insert this:

found = false; while (

found=false; while (

db_field = mysql_fetch_assoc(

db_field = mysql_fetch_assoc(
