This is a digital freelancing marketplace that will connect talented professionals with economic opportunities and give organisations access to affordable and low-risk human capital.

It is created from scratch without any libraries or frameworks (apart from phpmailer) as part of a school project.

All the application code is located within the freelance folder. It is organised in an MVP structure, with the following folders:

The Model component corresponds to all the data-related logic that the user works with. This can represent either the data that is being transferred between the View and Controller components or any other business logic-related data.

Most of the models are simple, they only contain a few properties and a few methods and represent tables in the database.

Most SQL queries are located here.

The view defines how the app's data should be displayed. It is used for all the UI logic of the application.

The views/_layout.php file is the main layout file that all the other views are rendered into.

The controller contains logic that updates the model and/or view in response to input from the users of the app.

They act as an interface between Model and View components to process all the business logic and incoming requests, manipulate data using the Model component and interact with the Views to render the final output.

• public/index.php: This is the main entry point of the application. All routes are defined here
• public/static/: This folder contains all the static files that are used throughout the application like CSS, JavaScript and fonts.
• public/uploads/: This folder contains all the uploaded files that are used throughout the application. It should not have been added to the repo - it was only added as a convenience with regard to presenting it as a school project.
• utils/: This folder contains all the utility classes that are used throughout the application.
• tasks/: This folder contains asynchronous tasks that should be run periodically.
• Router.php: This is the main file that handles all the routing logic of the application.
• Settings.php: This is the main configuration file that contains all the configuration variables.
• Database.php: This is the main file that contains all the database connection logic.
• db_schema.sql and db_schema.png: These are the database schema files.
• db_data.sql: This is the database (backup) data file. Again, it should not have been added to the repo - it was only added as a convenience with regard to presenting it as a school project.
• .env.example: contains all environment variables that should be set.

Clone the repository to your local machine.

git clone https://github.com/paulonteri/freelance-marketplace.git

You will need to install Composer following the instructions on their site.

From the freelance directory, run the following command:

composer update

Set up a MySQL database on your local machine with the following configuration as defined in Database.php:

- Database name: freelance
- Username: freelance
- Password: freelance

You can alternatively use a database connection string to connect a database by setting the CLEARDB_DATABASE_URL environment variable.

Set up schema:

Use the SQL in the db_schema.sql file to create the database schema.

Set up data (Optional):

Use the SQL in the db_data.sql file to populate the database with some data.

Check out the environment variables used by the app in the env.example file.

Mails are sent via smtp.gmail.com (Gmail). See more in utils/Mailer.php.

Set the following environment variables to get it working:

• MAIL_USERNAME: Your Gmail email address.
• MAIL_PASSWORD: Your Gmail password.

This app curretly uses the M-Pesa Express (LIPA NA M-PESA Online API / STK Push) and Business To Customer (B2C) (Pay Outs / Bulk Disbursements) APIs. See more in utils/JobMpesaPaymentHelper.php.

Get started by signing up for an MPESA Daraja API account and set up a payment gateway for the application.

The next step is to create a new sandbox app by clicking on the Add a New App button and give it a name. Ensure you select both Lipa na Mpesa Sandbox and Mpesa Sandbox.

Take note of the following from the dashboard and set them as environment variables:

• MPESA_CONSUMER_KEY
• MPESA_CONSUMER_SECRET
• MPESA_PASSKEY
• MPESA_SECURITY_CREDENTIAL
• MPESA_BUSINESS_SHORT_CODE

Tip, the above can be easily found from the API simulators in the Safaricom developer portal.

Note that for the Mpesa callbacks to work the app must be accessible from the internet and the correct host has been set via the HOST_URL environment variable.

Once ready to go for live payments, set the MPESA_ENV to live. The default is sandbox.

Learn more from the MPESA documentation here.
