The Datarecord class is one of the core classes of Platform, as it allows you to create highly flexible objects that are easily stored in a database.
You can look for the Templateclass class which provides a blueprint for your own Datarecord class and can easily be altered to your own purpose.

Preparing the database
Platform4PHP uses the MySQL database. There are two steps for preparing the database. First we need to create the global database, and if we want to use the full capabilities of Platform4PHP's ability to work with instances, we also need a database user that is allowed to create new databases.text/html2020-11-11T21:04:07+00:00Anonymous (anonymous@undisclosed.example.com)t1.2_preparing_folders

Preparing folders
Platform4PHP needs three separate directories. A log directory, a temporary directory and a storage directory, all with full permissions for both the web server user and the cron job user (more about this later).
The log directory is for common logs, the temporary directory is for temporary files and the storage directory is used for all file storage, for example when uploading and storing files.text/html2020-11-11T21:48:08+00:00Anonymous (anonymous@undisclosed.example.com)t1.3_installing_platform4php

Installing Platform4PHP
Just copy the entire distribution into your website folder. Be aware that Platform4PHP creates a configuration file in the parent folder of the website root, so be sure your folder configuration can handle this.

Instances and servers
Platform4PHP is intended as a multi-instance platform, where each instance is a copy of the application with its own database and own file storage. Platform4PHP supports multiple servers naturally, but works perfectly on a single server.text/html2021-03-10T20:03:21+00:00Anonymous (anonymous@undisclosed.example.com)t1.5_creating_user_registration_and_login_form_field

Managing security
Once inside your application, you need to make sure that only users that are logged in, have access. This is very easily accomplished by:
\Platform\Accesstoken::validateSession('/login/');
This validate the user session and extends it for a period of time. If the session cannot be validated the user is returned to the giventext/html2021-03-10T20:47:21+00:00Anonymous (anonymous@undisclosed.example.com)t1.7_creating_a_data_structure_for_employees_and_departments_datarecord

Datarecords
The Datarecord class is the most central object in Platform and therefore it is imperative to understand it. It is used to create most or all data objects used in your application.
In this tutorial we will use it to build a Department object representing the departments in our company and a Employee object representing the employees working in the different departments.text/html2021-03-10T21:15:33+00:00Anonymous (anonymous@undisclosed.example.com)t1.8_validating_datarecord_objects_and_some_notes_about_deletions_datarecord

Datarecord validation
This chapter is a little intermezzo and you can continue to the next chapter if you are eager to keep building the application.
In order to keep performance of Platform at a maximum, internal object integrity isn't performed when using Datarecord objects, so if you forget anything in the definition or link something wrong together, this will most likely cause an error. For debug purposes Datarecord therefore contains a function called renderIntegrityCheck which will valid…text/html2021-03-11T06:35:09+00:00Anonymous (anonymous@undisclosed.example.com)t1.9_creating_a_user_interface_for_the_data_datarecordeditcomplex

Interfaces for managing data
This is actually really easy.
On our page for managing departments, we do this:
Department::renderEditComplex();
...and on our page for managing employees, we do this:
Employees::renderEditComplex();
This renders a DatarecordEditComplex which is a complete interface for managing data of the designed type.text/html2021-03-11T20:04:01+00:00Anonymous (anonymous@undisclosed.example.com)t1.10_creating_an_interface_for_searching_data_filter_condition

Creating a search interface
Now we will create a search function for searching through employees. Here we will introduce filters which is another powerful feature of Platform. But first lets spice things up a little.
To make our Employee object a little more interesting, we add an age property, by extending the array intext/html2021-03-11T20:20:48+00:00Anonymous (anonymous@undisclosed.example.com)t1.11_adding_a_profile_picture_file

Adding a profile picture
We now want to be able to add profile pictures of the employees. This is also one of the really easy ones.
We once again extends the Employee object, by adding to the buildStructure() function:

Table class
Table is a PHP wrapper for the Tabulator javascript library, based of the Component class.
A basic table
The most basic table is created like:
$table = new Table();
// The setTabulatorOption function is used to pass options to the javascript tabulator function.
$table->setTabulatorOption('ajaxUrl', '/url-to-fetch-data');
$table->setTabulatorOption('columns', array(some column data));
// This renders the necessary html

The time class provides an abstraction on top of PHP date functions, providing easier functions and handling of time zones.
