  1. I have a challenge to solve regarding PDO and executing prepared statements inside a class. The way I made the script now is giving an error as output, though the outcome required is okay. The error type is: Fatal error: Uncaught ArgumentCountError: Too few arguments to function fruit_stock::get_fruit(), 0 passed in Could it be the error is caused because PHP requires that the execute() part should be defined or something like that? I really dont get what to do with it or with $stmt . . This are the scripts and the table so you can test it yourself. I'm curious how this is done. database table : -- phpMyAdmin SQL Dump -- version 4.7.4 -- https://www.phpmyadmin.net/ -- -- Host: localhost:3306 -- Generation Time: Oct 04, 2018 at 08:42 AM -- Server version: 5.7.19 -- PHP Version: 7.1.9 SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO"; SET AUTOCOMMIT = 0; START TRANSACTION; SET time_zone = "+00:00"; /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8mb4 */; -- -- Database: `test_fruit` -- -- -------------------------------------------------------- -- -- Table structure for table `fruit` -- DROP TABLE IF EXISTS `fruit`; CREATE TABLE IF NOT EXISTS `fruit` ( `rec_nr` int(2) NOT NULL AUTO_INCREMENT, `fruit_type` varchar(50) DEFAULT NULL, `amount` int(3) NOT NULL, `created_on` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `changed_on` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`rec_nr`,`created_on`,`changed_on`) ) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=latin1; -- -- Dumping data for table `fruit` -- INSERT INTO `fruit` (`rec_nr`, `fruit_type`, `amount`, `created_on`, `changed_on`) VALUES (1, 'apple', 5, '2018-10-04 06:01:48', '2018-10-04 06:01:48'), (2, 'strawberry', 20, '2018-10-04 06:01:48', '2018-10-04 06:01:48'), (2, 'banana', 15, '2018-10-04 06:02:54', '2018-10-04 06:02:54'), (4, 'grapes', 9, '2018-10-04 06:02:54', '2018-10-04 06:02:54'); COMMIT; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; Script 1: <?php // run class $amount = '20' ; include 'fruit-class1.php'; $tel_wrg = new fruit_stock('$amount'); $tel_wrg -> get_fruit($amount); var_dump($tel_wrg); echo $tel_wrg -> get_fruit(); ?> Script 2 : <?php // test classes class fruit_stock { var $amount; public $get_fruit; public function get_fruit($amount ) { var_dump($amount); var_dump($this); $servername = "your host"; $username = "your name"; $password = "your password"; $dbname = "test_fruit"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } // PREPARED if ($stmt = $conn->prepare("SELECT fruit_type FROM fruit WHERE amount = ? ; " )) { $stmt->bind_param('i', $amount); // $stmt->execute(); $stmt->bind_result($fruit_type); while ($stmt->fetch()) { var_dump($fruit_type); } } } }

    OOP error

    Hi everyone, I have something like more advanced problem, so I hope someone will help. No need for looking for variables and functions matches, I have good editor, and if there is any, it is because I am translating code to english. Here I have class DBobject, which contains all common database methods, but my focus is on two: public static function find_by_sql($sql) { global $pdo; // pdo connection works fine $query = $pdo->query($sql); $object_array = array(); while($row = $query->fetchAll()) { $object_array[] = static::instantiate($row); } return $object_array; } public static function instantiate($row) { $class = get_called_class(); $object = new $class; // because it can be used for users, pages... I don't wont to repeat my code foreach ($row as $attribute => $value) { $object->$attribute = $value; } return $object; } It is parent class of many classes, and I am looking in the class Comments protected static $table_name='komentari';protected static $db_fields=array(// all of my fields are here);public $id;public $user_id;// and all of database fields as variables And now, when I want to call it... $comment = Comment::find_by_sql(// here I select user based upon id); // this should return object with attributes from my database (because I returned object in instantiate function), am I right?echo $comment->content; // I exept here to echo lorem ipsum dolor sit amet.... And I get error that I called attribute of non-object $comment, aldo I returned the object in instantiate method

  8. I have been given a flash website to amend. It has a home page and videos page already done. I have to add a links page, books page and a social page with a twitter feed. It all has to be done using OOP in separate As files. Can anybody give me some guidelines on how to do this correctly? Thanks Guys
