为什么我的文件processApplication.php中出现错误?
我只是想使用我的数据库类来获取MySQL连接,这样我就可以在执行之前准备好我的SQL语句。
变量$_POST['status']
,$currentDate
和$_POST['id']
确实有值,因为我在不使用数据库类的情况下测试了它,而是使用mysqli_connect
语句。< / p>
请帮忙吗?
processApplication.php
<?PHP
include_once '../lib/variables.php';
include_once '../lib/database.php';
//make sure user is valid
if(check_ses_vars() != '') {
date_default_timezone_set('America/New_York');
$currentDate = date('m/d/Y');
$query = "UPDATE Application SET hasBeenPushed = ?, pushedDate = ? WHERE applicationId = ?";
$db = Database::get();
$stmt = $db->prepare($query);
$stmt -> bind_param("isi", $_POST['status'], $currentDate, $_POST['id']);
$results = $stmt->execute();
}
?>
和Database.php:
include_once "variables.php";
class Database {
var $database_name;
var $database_user;
var $database_pass;
var $database_host;
var $database_link;
private static $instance;
function Database($user=null, $pass=null, $host=null, $name=null)
{
$this->database_user = isset($user)?$user:$GLOBALS["db_user"];
$this->database_pass = isset($pass)?$pass:$GLOBALS["db_pass"];
$this->database_host = isset($host)?$host:$GLOBALS["db_host"];
$this->database_name = isset($name)?$name:$GLOBALS["db_name"];
}
public static function get()
{
if (!isset(self::$instance)) {
$c = __CLASS__;
self::$instance = new $c;
self::$instance->connect();
}
return self::$instance;
}
function connect()
{
$this->database_link = new mysqli(
$this->database_host,
$this->database_user,
$this->database_pass,
$this->database_name
);
/* check connection */
if (mysqli_connect_errno($this->database_link)) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
}
}
答案 0 :(得分:1)
$stmt -> bind_param("isi", $_POST['status'], $currentDate, $_POST['id']);
空格应该创建一个解析错误,如Parse error: syntax error, unexpected '->' (T_OBJECT_OPERATOR)
?
