<?php
require("myActiveRecord.php");

// this assumes that you have set your db authentication up in ActiveConnect.php

$activeRecord = new ActiveRecord('users'); //create a new object based on the table users
//
// Now we are going to create a new user:
//

// first we set values to all the fields in the Users table:
$activeRecord->username = "AppleSeed";
$activeRecord->firstname = "Johnny";
$activeRecord->lastname = "McIntosh";
$activeRecord->password = md5("myPassWord");

// Now we save the new record
$activeRecord->save();

// if the save was successful then it will not die and
// the id will be set to the last entry so you can 
// reference it with: $activeRecord->id

// Lets say we made a mistake, we need the firstname to be 
// John not Johnny, in this case we can update it using:

$activeRecord->firstname = "John";

// because $activeRecord->id was set to the id of the record we created,
// it will update that corresponding rows related to that id.
$activeRecord->save();

// now we want to update an older record, so we will need to find the user id 
// with the username and password and then update based on the return id.

$userid = $activeRecord->getUseridWhere("username = 'wattz' AND password='passw0rd'");

// now we have the user's id, and we want to update the users email address and save the record:
$activeRecord->id = $userid;
$activeRecord->email = "wattz@email.com";
$activeRecord->save();

//...and thats it for that part

//
// Now we want to get all the users that have the db field "role" set to admin
// this is easy using myActiveRecord
// all we have to do is:

$adminUsers = $activeRecord->findByRole("admin");
// this will return all of the users in the db table with the Role "admin";
// to see the results simple do a var_dump or print_r.

// to delete a row, you simply use the delete command:
$activeRecord->deleteByEmail("wattz@email.com");

// myActiveRecord also includes simple static functions like:
$adminUsers = $activeRecord->findAll(); //returns all the records in a table
$adminUsers = $activeRecord->findAllWhere("role='admin"); //if you dont prefer the dynamic methods

// and if you have some strange query you need to run
// there is always the straight query command:
$adminUsers = $activeRecord->query("SELECT * FROM users WHERE role='admin'");

// and finally we have fieldCount, which simply gives you a total count of fields, 
// with our without parameters

// total number of admin users
$adminUserCount = $activeRecord->fieldCount("role='admin'");

// total number of users.
$userCount = $activeRecord->fieldCount();

// There is much more about myActiveRecord that can be accomplished, visit www.wattz.net to download
// and utilize php and mysql with easy.
