Заполните DataTable с базой данных MySQL

1 голос
/ 08 ноября 2019

Я пытаюсь создать приложение CRUD. У меня есть база данных MySQL с большим количеством записей, и я хотел бы использовать JQuery DataTable, а не пытаться кодировать таблицу с нуля. У меня проблема в том, что я вижу таблицу на своем сайте, но не могу заставить ее извлекать данные из MySQL.

Я пробовал читать многие сайты и форумы, включая официальную документацию по DataTable. веб-сайт, но ничего из этого не имеет смысла для меня.

Что мне нужно сделать, чтобы это исправить? Я работаю над этим проектом уже целую неделю и разочаровываюсь.

// DB table to use
$table = 'members';

// Table's primary key
$primaryKey = 'id';

// Array of database columns which should be read and sent back to DataTables.
// The `db` parameter represents the column name in the database, while the `dt`
// parameter represents the DataTables column identifier. In this case simple
// indexes
$columns = array(
    array( 'db' => 'id', 'dt' => 0 ),
    array( 'db' => 'name',  'dt' => 1 ),
    array( 'db' => 'residential_address', 'dt' => 2 ),

Теперь, когда у вас есть данные MySQL в JSON с использованием PHP , используйте параметр AJAX в DataTable, чтобы он отражал вашу таблицу: 

$(document).ready(function() {
    $('#example').DataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": "../server_side/scripts/server_processing.php" // your php file
    });
});
