Examples

Connect to the Database

First of all, the application needs information to connect to the database

use CrudAdvanced\DataBase;

DataBase::configure('127.0.0.1', 'root', 'password', 'dbteste');

Using Crud

To create a class and use the Crud Methods, you need to extends Crud to your class.

use CrudAdvanced\Val;
use CrudAdvanced\Crud;

class User extends Crud {

	/* Database table definition */
	public $table = "users"; // Define Table name
	public $tableCols = ['name', 'email', 'password']; // Define table cols

	/*
	 * Other class methods and attributes can be defined freely.
	 */
}

Insert new user with dbInsert()

This method will insert all the attributes to the database. Be aware of the name of the attributes, they must be exactly the same as the fields in the database.

$user = new User([
	'name' => 'Yohan Cayres',
	'email' => 'yohan.cayres@mail.com',
	'password' => md5('somepassword')
]); // Create new object type User

$user->dbInsert(); // Insert at the Database

dbLoadDataBy()

This method will load attributes from database, making the search for the defined attribute.

$user->dbLoadDataBy('email', 'id,name,password'); // Loads a database attribute by email.
echo $user->_get('id');

Update some row with dbUpdateAll() or dbUpdateAtts()

This method needs the id attribute, you can get it through dbLoadDataBy();

$user->_set('email', 'newMail@mail.com'); // This will set a new email

$user->dbUpdateAtts('email'); // Only the attribute 'email' will be updated
$user->dbUpdateAll(); // All the attributes will be updated

Update directly

This method needs the id attribute, you can get it through dbLoadDataBy();

$user->dbUpdate('email', 'newMail@mail.com'); // Set and update directly.
