我将mysqli连接更改为PDO语句,因此我的页面上出现了很多错误,这是我的代码请帮助我们
。 。
if ($fn && $ln && $e && $p) { // If everything's OK...
// Make sure the email address is available:
//$q = "SELECT user_id FROM users WHERE email='$e'";
$q = $dbc->query("SELECT user_id FROM users WHERE email='$e'");
$q->execute(array($e));
$r = $q->fetchAll(PDO::FETCH_ASSOC);
//$r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc));
if (mysqli_num_rows($r) == 0) { // Available.
// Create the activation code:
$a = md5(uniqid(rand(), true));
答案 0 :(得分:0)
以下是您转换为PDO的代码。
// Make sure the email address is available:
$q = $dbc->query("SELECT user_id FROM users WHERE email=?");
$q->execute(array($e));
$r = $q->fetchColumn();
if (!$r) { // Available.
// Create the activation code:
$a = md5(uniqid(rand(), true));
有三件事已经纠正
fetchColumn
代替fetchAll
