我在选择数据库中最新/匹配的行时遇到很大麻烦。
例如:
$query = "SELECT * FROM `Password_Reset`";
$request = mysql_query($query,$connection) or die(mysql_error());
$result = mysql_fetch_array($request);
无论每次运行查询, $result['token']
都会占用第一行。
我很确定这与我的选择查询不够具体,但我找不到匹配它的方法。
甚至更具体。这是整个查询:
$query = "SELECT * FROM `Password_Reset`";
$request = mysql_query($query,$connection) or die(mysql_error());
$result = mysql_fetch_array($request);
$token = $result['token'];
$alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcedfghijklmnopqrstuvwxyz1234567890";
$rand = str_shuffle($alpha);
$salt = substr($rand,0,40);
$hashed_password = sha1($salt . $_POST['Password']);
$user_email = $result['email'];
// these should match, and do so every where else on my other pages and in the db, I'm just not able to pull the corresponding $token. its taking the $token in the first row every time.
if($get_token == $token) {
header("Location: http://www.cysticlife.org/index.php");
exit;
}else{
if(empty($_POST['Password'])) {
$valid = false;
$error_msgs[] = 'Whoops! You must enter a password.';
}
if($_POST['Password'] != $_POST['passwordConfirm'] || empty($_POST['Password'])) {
$valid = false;
$error_msgs[] = "Your password entries didn't match...was there a typo?";
}
if($valid) {
$query = "UPDATE `cysticUsers` SET `encrypted_password` = '$hashed_password' WHERE `Email` = '$user_email'";
mysql_query($query,$connection);
}
}
}
提前致谢

如果您想在按行提交数据库时对其进行排序,则需要在表中添加ID字段(如果尚未添加)。
这可能是向表中添加名为id
的字段,将其设置为索引并使用auto_increment
的最简单方法。然后,您只需按ID订购行:
SELECT * FROM `Password_Reset` ORDER BY `id` ASC
顺便说一句,如果您只需要第一行,最好在查询中添加LIMIT 1
,以获得更好的效果。
