这是我当前的代码
function getUserDetails($username=NULL, $id=NULL) {
if($username!=NULL) {
$column = "user_name";
$data = $username;
}
elseif($id!=NULL) {
$column = "id";
$data = $id;
}
global $db;
$query = $db->prepare("SELECT id, username, permissions, forename, surname, password, email, courseid, choiceid, lastlogin, active FROM users WHERE $column = :column");
$query->bindParam(":column", $data);
$query->execute();
$query->bind_result ($id, $username, $permissions, $forename, $surname, $password, $email, $courseid, $choiceid, $lastlogin, $active);
while ($query->fetch()){
$row = array('id' => $id, 'userlevel' => $permissions, 'username' => $username, 'forename' => $forename, 'surname' => $surname, 'password' => $password, 'email' => $email, 'courseId' => $courseid, 'choiceId' => $choiceId, 'lastlogin' => $lastlogin, 'active'=> $active);
}
return ($row);
}
我一直在尝试将其转换为 pdo,因为我发现 bind_result 不适用于 pdo - 谁能帮助我知道我应该做什么?
我已经读过我应该使用 fetch?但我真的很困惑。

我试过这个:
function getUserDetails($username=NULL,$id=NULL) {
if($username!=NULL) {
$column = "user_name";
$data = $username;
}
elseif($id!=NULL) {
$column = "id";
$data = $id;
}
global $db;
$query = $db->prepare("SELECT id, username, permissions, forename, surname, password, email, courseid, choiceid, lastlogin, active FROM users WHERE $column = :column");
$query->bindParam(":column", $data);
$query->execute();
$results = array();
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
$results[] = $row;
}
return ($results);
}
这是朝着正确方向迈出的一步吗?

将我的代码更新为:
function getUserDetails($username) {
global $db;
$query = $db->prepare("SELECT * FROM users WHERE username = :username");
$query->bindParam(":username", $username);
return $query->fetch(PDO::FETCH_ASSOC);
}
$username = 'uname';
$result = getUserDetails($username);
print_r($result);
但是它什么也没打印。用户名肯定存在。
我尝试了一个带有一些虚拟数据的测试数据库
$data = '2';
$sth = $db->prepare("SELECT * FROM test WHERE id = :id");
$sth->bindParam(":id", $data);
$sth->execute();
$result = $sth->fetch(PDO::FETCH_ASSOC);
print_r($result);
我试图弄清楚我如何访问打印数组中的内容:数组的输出为
Array ( [Id] => 2 [Name] => tom )
我(例如)怎么做
$name = $result['name']; //line 67
当我尝试该代码时,我得到
Notice: Undefined index: name in <directory>\test.php on line 67
弄清楚了!
function getUserDetails($username) {
global $db;
$sth = $db->prepare("SELECT id, username, permissions, forename, surname, password, email, courseid, choiceid, lastlogin, active FROM users WHERE username = :username");
$sth->bindParam(":username", $username);
$sth->execute();
$result = $sth->fetch(PDO::FETCH_ASSOC);
return $result;
}
$username = 'un';
$userdetails = getUserDetails($username);
echo $userdetails['forename'];
它给了我正确的答案!感谢您的帮助
