我使用下面的代码来确保只有确认的用户(确认为 1,否则为 0)可以登录,但无论如何此代码都会显示道歉消息。我怎样才能解决这个问题?谢谢!
// make sure the user is confirmed
$confirmstatus = query("SELECT * FROM users WHERE username = ?", $_POST["username"]);
if ($confirmstatus["confirmed"] == 0)
{
apologize("Please first confirm your account.");
}
这是查询功能
/**
* Executes SQL statement, possibly with parameters, returning
* an array of all rows in result set or false on (non-fatal) error.
*/
function query(/* $sql [, ... ] */)
{
// SQL statement
$sql = func_get_arg(0);
// parameters, if any
$parameters = array_slice(func_get_args(), 1);
// try to connect to database
static $handle;
if (!isset($handle))
{
try
{
// connect to database
$handle = new PDO("mysql:dbname=" . DATABASE . ";host=" . SERVER, USERNAME, PASSWORD);
// ensure that PDO::prepare returns false when passed invalid SQL
$handle->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
}
catch (Exception $e)
{
// trigger (big, orange) error
trigger_error($e->getMessage(), E_USER_ERROR);
exit;
}
}
// prepare SQL statement
$statement = $handle->prepare($sql);
if ($statement === false)
{
// trigger (big, orange) error
trigger_error($handle->errorInfo()[2], E_USER_ERROR);
exit;
}
// execute SQL statement
$results = $statement->execute($parameters);
// return result set's rows, if any
if ($results !== false)
{
return $statement->fetchAll(PDO::FETCH_ASSOC);
}
else
{
return false;
}
}
这是道歉功能
/**
* Apologizes to user with message.
*/
function apologize($message)
{
render("apology.php", ["message" => $message]);
exit;
}
和渲染功能。
/**
* Renders template, passing in values.
*/
function render($template, $values = [])
{
// if template exists, render it
if (file_exists("../templates/$template"))
{
// extract variables into local scope
extract($values);
// render header
require("../templates/header.php");
// render template
require("../templates/$template");
// render footer
require("../templates/footer.php");
}
// else err
else
{
trigger_error("Invalid template: $template", E_USER_ERROR);
}
}
