Contributing to thirty bees

thirty bees is an open-source e-commerce solution, forked from PrestaShop. We'd like to encourage everyone to participate in the project, including contributing your own improvements to the source code.

Procedure

In order to contribute to this project, you need to be familiar with Git, an open source version control system used extensively by thirty bees developers, as well as GitHub:

Contributing to this project via Git can be done as follows:

  • Fork this project to your own GitHub account
  • Recursively clone this project to your local machine (use e.g. git clone [email protected]:username/ThirtyBees.git --recursive)
  • Optionally install the dependencies of this project to test it on your local machine (composer install in the root directory)
  • Create your own local branch (git checkout -b mybranch)
  • Make your changes
  • Commit (git commit -m "Commit message"). We do not have a commit message norm, but do make sure you use the present tense!
  • Then push the commit to your own fork (git push -u origin mybranch)
  • Visit either the fork or the thirty bees repository and GitHub should ask you to make a pull request. Follow this procedure and wait for one of our developers to include your changes into the codebase or tell you about possible improvements your pull request might need.

That's it. Thank you for your contribution!

Coding standards

We like to aim for a very high quality open source e-commerce platform. This means that we need to implement high quality standards, guidelines and coding styles that should be used by everyone participating in the project, at all times. Not abiding by the project's coding standards may be a reason to decline your contribution, so be sure to read this section in order to maximize the chance of your changes to land in thirty bees' codebase.
The majority of thirty bees is written in PHP, but in our codebase you will also find JavaScript, HTML, CSS, Smarty templates, SQL, XML and JSON. For these languages we use the following code standards:

SQL Guidelines

Table names

  1. Table names must begin with thirty bees' _DB_PREFIX_ prefix.
  2. Table names must have the same name as the object they reflect: ps_cart (replace ps_ with your own prefix).
  3. Table names are singular: ps_order
  4. Language data has to be stored in a table named exactly like the object's table, but also has the _lang suffix: ps_product_lang.
  5. The same goes for specific shop data. These tables require the _shop suffix.

SQL Query

  1. For simple queries the DbQuery class MUST be used:

    $sql = new DbQuery();
$sql->select('p.`name`');
$sql->from('product', 'p');
$sql->innerJoin('product_lang', 'pl', 'p.`id_lang` = pl.`id_lang`');
$sql->where('pl.`id_lang` = 1');

  2. When referring to an ObjectModels primary key or table name, use the escaped $definition property:

    $sql = new DbQuery();
$sql->select('p.`'.bqSQL(self::$definition['primary']).'`');
$sql->from(bqSQL(self::$definition['table']), 'p');
$sql->where('p.`'.bqSQL(self::$definition['primary']).'` = 1');

  3. Keywords in raw db queries must be written in uppercase.

    SELECT `firstname`
FROM `'._DB_PREFIX_.'customer`

  4. Table aliases have to be named by taking the first letter of each word and must be lowercase:

    $sql = new DbQuery();
$sql->select('p.`'.bqSQL(self::$definition['primary']).'`');
$sql->from(bqSQL(self::$definition['table']), 'p');
$sql->where('p.`'.bqSQL(self::$definition['primary']).'` = 1');

  5. When conflicts between table aliases occur, the second character also has to be used in the name:

    $sql = new DbQuery();
$sql->select('ca.`'.bqSQL(Product::$definition['primary']).'`, cu.`firstname`');
$sql->from(bqSQL(Cart::$definition['table']), 'ca');
$sql->innerJoin(bqSQL(Customer::$definition['table']), 'cu', 'ca.`'.bqSQL(Customer::$definition['primary']).'` = cu.`'.Customer::$definition['primary']).'`');

  6. A new line has to be created for each clause in raw db queries:

    $sql = 'SELECT pl.`name`
FROM `'._DB_PREFIX_'.product_lang` pl
WHERE pl.`id_product` = 17';

  7. It is forbidden to make a JOIN in a WHERE clause
