Git Hooks - A very basic guide

The aim of this guide is to create the basic idea of how to set up a very basic hook. Once you've read through this guide, please read through the Git Hooks Documentation. But first...

What is a Git Hook?

In very basic terms, it's a thing that "fires off custom scripts when certain important actions occur". For example, each time we make a commit, a git hook will run some code that does some cool stuff automatically. Because sometimes we want stuff to happen automatically and Git Hooks help us do that!

Give me an example!

Oh, sure. Imagine a conversation between you and your supervisor that goes like this:

	<?php

	$results = array();

	# The "$selected_functions" array will be constructed on the client side and posted to the PHP controller function.
	# Populate the "$selected_functions" array based on user interaction with the UI.

	$selected_functions = array(
	"function_1" => array("parameter_1_1", "parameter_1_2", "parameter_1_3"),
	"function_2" => array("parameter_2_1"),

	select
	pc_games.title,
	to_char(pc_games.release_date, 'YYYY-MM-DD') as release_date
	array_to_string(array_agg(avid_fans.firstname \|\| ' ' \|\| avid_fans.surname), ', ', null) as fans
	from
	schema_A.pc_games as pc_games
	inner join schema_A.avid_fans as avid_fans on (pc_games.id = avid_fans.fk_pc_game_id)
	where
	pc_games.release_date > '2004-12-31'
	group by

	-- To view all values in the enum:
	SELECT unnest(enum_range(NULL::schema.enum_name));

	-- To add a value to the enum:
	ALTER TYPE schema.enum_name ADD VALUE 'new_enum_value';
