在过去的两天里,我一直在研究一个项目,无论我尝试什么,我都会遇到某种错误,或者某些东西不起作用。在这一点上,我被告知我正在调用一个未定义的方法,上传:prepare(),这是真的,因为该类被称为上传,语句是$ this-> prepare()....等等。
我很沮丧,无论我做什么,我都无法理解这一点。
classes.php
<?php
require('config.php');
error_reporting(E_ALL);
/*
* Classes required by the script
*
*/
class database extends PDO
{
public $conURL;
public function __construct($config) {
$conURL = "mysql:host=" . $config['host'] . ";dbname=" . $config['db'];
try {
parent::__construct($conURL, $config['user'], $config['pass']);
} catch (PDOException $e) {
$e->getMessage();
}
}
}
class upload
{
public $_FILES;
public function uploadFile() {
if ($_FILES['file']['size'] >= 2000000) {
echo "File is too large!";
}
elseif (isset($_FILES['file'])) {
$stmt = $this->prepare("INSERT INTO upload (name, type, size, content) VALUES (?, ?, ?, ?)");
$stmt->execute(array($_FILES['file']['name'], $_FILES['file']['type'], $_FILES['file']['size'], $_FILES['file']['file']));
}
}
}
的config.php
<?php
$config = array(
'host' => 'localhost', // db host
'user' => 'root', // db user
'pass' => 'mypassword', //db pass
'db' => 'files' // db name
);
upload.php的
<?php
error_reporting(E_ALL);
require('config.php');
require('classes.php');
$dbh = new database($config);
$upload = new upload();
$upload->uploadFile();
答案 0 :(得分:0)
您试图调用prepare
的{{1}}函数,而不是upload
。试试这个:
database

我认为您打算使用database->prepare
代替this->prepare
?
您需要将上传类作为数据库实例(或者即时创建)。
