Question

我不断收到错误，我必须在我的代码中正确输入两个新密码。那不是我想要的。如果填写了密码字段，则应检查密码是否匹配并符合要求。否则，它应该更新配置文件。但它不这样做。 IT仍会检查密码字段。你能告诉我我的代码出错吗？

    <?php
    if ($post == "yes") {


    $uppercase = preg_match('@[A-Z]@', $password);
    $lowercase = preg_match('@[a-z]@', $password);
    $number    = preg_match('@[0-9]@', $password);

    if (isset($password) && ($password != $password2 || !$uppercase || !$lowercase ||    !$number || strlen($password) < 8)) {
    echo "<table class=tablenews><tr><td>There is an error with your passwords. Either they do not match, or your new password does not contain 8 characters, a number, a lower and an upper case letter. Go back and retry again. </td></tr></table>";

    }

    else {
     $password = generateHash($password);

    $result = mysql_query("UPDATE users SET avatar='" . $avatar . "' WHERE id='". $_SESSION['user_id'] . "'") 
    or die(mysql_error());  
    $result = mysql_query("UPDATE users SET u_signature='" . $signature . "' WHERE id='".   $_SESSION['user_id'] . "'")

or die(mysql_error()); 
printf('<script>window.location = "http://www.sw-bfs.com/index.php?siteid=profileedit"</script>');

Answer 1

if (isset($_POST['password']) ...) {
    // ... display error
}

这意味着如果password数组中存在$_POST密钥，则显示错误。我认为你的意思是如果password数组中<{1}}键不存在，则显示错误。你应该在它之前放一个$_POST来反转if：

这是否能达到您想要做的目的：

if(isset($password)) {
    if ($password != $password2 || !$uppercase || !$lowercase || !$number || strlen($password) < 8) {
        error_log('error');
    echo "<table class=tablenews><tr><td>There is an error with your passwords. Either they do not match, or your new password does not contain 8 characters, a number, a lower and an upper case letter. Go back and retry again. </td></tr></table>";

    } else {
        $password = generateHash($password);

        $result = mysql_query("UPDATE users SET avatar='" . $avatar . "' WHERE id='". $_SESSION['user_id'] . "'")
        or die(mysql_error());
        $result = mysql_query("UPDATE users SET u_signature='" . $signature . "' WHERE id='".   $_SESSION['user_id'] . "'")
         or die(mysql_error());
        $result = mysql_query("UPDATE users SET u_bio='" . $bio . "' WHERE id='".    $_SESSION['user_id'] . "'")
        or die(mysql_error());
        $result = mysql_query("UPDATE users SET u_desc='" . $desc . "' WHERE id='". $_SESSION['user_id'] . "'")
        or die(mysql_error());
        $result = mysql_query("UPDATE users SET u_intro='" . $intro . "' WHERE id='".     $_SESSION['user_id'] . "'")
        or die(mysql_error());
            $result = mysql_query("UPDATE users SET password='" . $password . "' WHERE id='". $_SESSION['user_id'] . "'")
        or die(mysql_error());
        printf('<script>window.location = "http://www.sw-bfs.com/index.php?siteid=profileedit"</script>');
    }
}

让剩下的代码保持不变，只需替换第一个if / else。

您的代码格式化可能会使用一些清理，您应该真正压缩mysql查询。
