Question

I started over with a project I was working on earlier. With the help of my PHP book and a few people on Stack Overflow, I was able to get rid of a lot of the errors I was getting.

Now, I am left with a warning and a fatal error. I understand both errors, I am just not sure how to fix the errors I am getting. Could anyone please help? I am not asking for anyone to write the code or just do everything for me, I just need a point in the right direction.

This is the warning, and it sounds like I need to put __construct somewhere in the uploadFile() method, but again, not sure about this:

Warning: PDO::prepare() [pdo.prepare]: SQLSTATE[00000]: No error: PDO
constructor was not called in C:\xampp\htdocs\files\upload.php on line
23

The second, I am just completely lost on what to do about. I realize what the error is telling me, I just don’t know where to start in terms of fixing it. Here it is:

Fatal error: Call to undefined method upload::bindParam() in
C:\xampp\htdocs\files\upload.php on line 24

If there’s anymore information I could provide that would make this easier to answer, please tell me and I will try to get it for you. I appreciate any help!

upload.php

  <?php
error_reporting(E_ALL);
require('config.php');

class upload extends PDO
{
    public $conURL, $filename, $tmpname, $filesize, $filetype, $file;

    public function __construct($config) {
        $conURL = "mysql:host=" . $config['host'] . ";dbname=" . $config['db'];
        parent::__construct($conURL, $config['user'], $config['pass']);

    }       

    public function uploadFile() {
        if ($_FILES['file']['size'] >= 2000000) {
           echo "File is too large!"; 
        }
        else {
            $sth = $this->prepare("INSERT INTO uploads (name, type, size, file) VALUES (?, ?, ?, ?)");
            $sth->bindParam(1, $filename);
            $sth->bindParam(2, $filetype);
            $sth->bindParam(3, $filesize);
            $sth->bindParam(4, $file);
            $sth->execute();
        }
    }
}

$upload = new upload($config);

$upload->filename = $_FILES['file']['name'];
$upload->tmpname = $_FILES['file']['tmp_name'];
$upload->filesize = $_FILES['file']['size'];
$upload->filetype = $_FILES['file']['type'];    
$upload->file = $_FILES['file'];


$upload->uploadFile();

config.php

<?php
$config = array(
        'host' => 'localhost', // db host
        'user' => 'root', // db user
        'pass' => '', //db pass
        'db' => 'files' // db name
);

Edit: Thanks to everyone here, only one error remains and it is the following:

Fatal error: Call to undefined method stdClass::uploadFile() in
C:\xampp\htdocs\files\upload.php on line 43

Edit 2: All errors have been resolved, but nothing is being inserted into the database.

Answer 1

Your constructor should look like:

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();
        }
}  

or even

public function __construct($config)
{
    $conURL = "mysql:host=" . $config['host'] . ";dbname=" . $config['db'];
    parent::__construct($conURL, $config['user'], $config['pass']);
}
