Javascript for PHP Geeks Tutorial

This repository holds the screencast code, script and all the AJAX you can eat for the Modern JavaScript Tutorials on KnpUniversity.

Setup

If you've just downloaded the code, congratulations!

To get it working, follow these steps:

Setup parameters.yml

First, make sure you have an app/config/parameters.yml file (you should). If you don't, copy app/config/parameters.yml.dist to get it.

Next, look at the configuration and make any adjustments you need (like database_password).

Download Composer dependencies

Make sure you have Composer installed and then run:

composer install

You may alternatively need to run php composer.phar install, depending on how you installed Composer.

Setup the Database

Again, make sure app/config/parameters.yml is setup for your computer. Then, create the database and the schema!

php bin/console doctrine:database:create
php bin/console doctrine:migrations:migrate
php bin/console doctrine:fixtures:load

If you get an error that the database exists, that should be ok. But if you have problems, completely drop the database (doctrine:database:drop --force) and try again.

Start the built-in web server

You can use Nginx or Apache, but the built-in web server works great:

php bin/console server:run

Now check out the site at http://localhost:8000

For convenience

If you are using PhpStorm you may install and enable the Symfony Plugin via the preferences which provides more auto-completion for Symfony projects.

Have fun!

Have some Ideas or Feedback?

And as always, thanks so much for your support and letting us do what we love!

If you have suggestions or questions, please feel free to open an issue or message us.
