Re create as objects and classes PHP - php

Question

I'm a little bit stumped. I've never messed around with objects and classes too much in PHP, but someone recommended that I re-did some code with it.
What I'm trying to do is make $auctions an object property, while saving all of the row data to it.
Right now, I do echo $auctions[1]['title']; to echo out the listing where id=1 title.
And I wish to re-create it so that it would be an object.
Here's my current code,
$sqlquery = "SELECT * FROM auctions";
if ($result = $db->query($sqlquery)) {
while ($row = $result->fetch_assoc()) {
$auctions[$row['id']]['id'] = $row['id'];
$auctions[$row['id']]['title'] = $row['title'];
$auctions[$row['id']]['featured_image'] = $row['featured_image'];
$auctions[$row['id']]['description'] = $row['description'];
$auctions[$row['id']]['date'] = $row['date'];
$auctions[$row['id']]['location'] = $row['location'];
$auctions[$row['id']]['highlights'] = $row['highlights'];
$auctions[$row['id']]['catagories'] = $row['catagories'];
$auctions[$row['id']]['notes'] = $row['notes'];
$auctions[$row['id']]['terms'] = $row['terms'];
$auctions[$row['id']]['contact'] = $row['contact'];
}
}
I don't have any idea on how to accomplish this, but if someone could give me a little hint to point me in the direction, it would be very appreciated! :)

Answer 1

Create a class auctions with all the needed member variables that you listed above (e.g. id, title, feature_image etc.). Next create a setter method (e.g. setValues()) inside the class that can accept the $row.
$sqlquery = "SELECT * FROM auctions";
$auction = new Auctions();
if ($result = $db->query($sqlquery)) {
while ($row = $result->fetch_assoc()) {
$auction->setValues( $row );
// do something with $auction...
}
}
Instead of a explicit setter method, You may also use magic method __set().

Answer 2

I'll write a minimal snippet here now:
First let create a base class for all our models:
abstract class Model() {
public $fields = array();
private $data = array();
public function setValues(array $vals) {
foreach($vals as $key=>$value) {
if (in_array($key, static::$fields)) {
$this->data[$key] = $value;
}
}
}
public function get($key) {
if (in_array($key, static::$fields) && isset($this->data[$key])) {
return $this->data[$key];
}
return null; // or throw Exception)
}
}
Next, create some concrete model:
class Users extends Model {
public static $fields = array('id', 'name');
}
And we can use it now:
$users = array();
$sqlquery = "SELECT * FROM Users";
if ($result = $db->query($sqlquery)) {
while ($row = $result->fetch_assoc()) {
$user = new User();
$user->setValues($row);
$users[] = $user;
}
}
You can to add some user-specific methods (aka login) to User model directly..
Also you should to implement other Model methods, like getById, getByQuery, save and other, and no use direct sql queries, because models can do this itself

Answer 3

You can store the values in a object like
$obj = new stdClass; //create new standard class object
$obj->id = $row['id']; //assign property value
$obj->title = $row['title'];
//further properties
... and so on

Answer 4

You really are trying to create an array of objects (instances of a type containing info for one auction. Something like this:
class Auction
{
var $id = null;
var $title = null;
var $featured_image = null;
var $description = null;
var $date = null;
var $location = null;
var $highlights = null;
var $catagories = null;
var $notes = null;
var $terms = null;
var $contact = null;
}
$sqlquery = "SELECT * FROM auctions";
if ($result = $db->query($sqlquery)) {
while ($row = $result->fetch_assoc()) {
$newAuction = new Auction();
$newAuction->id = $row['id'];
$newAuction->title = $row['title'];
$newAuction->featured_image = $row['featured_image'];
$newAuction->description = $row['description'];
$newAuction->date = $row['date'];
$newAuction->location = $row['location'];
$newAuction->highlights = $row['highlights'];
$newAuction->catagories = $row['catagories'];
$newAuction->notes = $row['notes'];
$newAuction->terms = $row['terms'];
$newAuction->contact = $row['contact'];
$auctions[$row['id']] = $newAuction;
}
}
Please note that you have misspelled "categories" (you have "catagories").

Answer 5

I advice you to use PDO
class Auction
{
public $id;
public $title;
public $featured_image;
public $description;
public $date;
public $location;
public $highlights;
public $catagories;
public $notes;
public $terms;
public $contact;
// This will return $all being an array of objects of class Auction
public static function getAll() {
$query = "SELECT * FROM auctions";
$statement = $db->prepare($query);
if (!$statement->execute())
return false;
$all = $statement->fetchAll(PDO::FETCH_CLASS, "Auction");
return $all;
}
}
