App Template
============
This is an empty (but fully functional) PHP application. It is designed to
integrate with AccountHub, an account management web interface. AccountHub manages
user credentials and account data, and is accessed by this app via [a simple API ](http://docs.netsyms.com/docs/AccountHub/API%20Documentation/ ).
Program Structure
-----------------
### Folders
* api
An API framework. See api/apisettings.php below.
* api/actions
A place to put your API actions.
* langs
Translations and alert messages.
The language files that are loaded depends on the value of `LANGUAGE` in `settings.php` .
All .json files in a language folder are parsed and loaded into the dictionary (use via `$Strings->get('some key')` ).
* lib
A good place to put helper functions that you don't want "in the way". All files that end with `.lib.php` are automatically loaded.
* pages
What it looks like. If you go into `pages.php` and define a page with the name `foo` , there should be a `foo.php` in here.
The app checks before loading, so it will give a friendly 404 error if it doesn't find your page.
Woe to you if you delete `home.php` or `404.php` , as those are assumed to exist for fallback behavior.
* static
CSS, JavaScript, fonts, images...
* vendor
If you don't know what this is about, or you don't have it, you need to read up on Composer. Right now.
### Files
* settings.template.php
App configuration. Copy to `settings.php` and customize. Documented with inline comments.
* app.php
Handles the web part of the app. If you have problems with too many items on the navbar, change `$navbar_breakpoint` .
To change the navbar colors, find and edit `<nav class="navbar ...` , changing `navbar-dark bg-blue` to suit.
* static/img/logo.svg
The app logo. Should be a square, we don't test any other sizes.
* required.php
The "duct tape" that holds the app together. Use `require_once __DIR__."/required.php"` at the top of every file.
It loads Composer dependencies, library files, app settings, language data, and creates `$database` for accessing the database.
It also has some utility functions, including `dieifnotloggedin()` .
Read through it to see exactly what it does.
* action.php
A good place to put form handling code. By default it only handles logging out, but is easily expanded.
* api/apisettings.php
An array of API actions. Validates any variables required by your actions before running them. See https://source.netsyms.com/Apps/NotePost/src/branch/master/api/apisettings.php for a full example of its capabilities.
* api.php
Legacy shim for code that still expects the API endpoint to be here.
* index.php
Handles login and checking permissions.
* app.php
Main app page after login. Handles loading app pages and 404 errors.
Redirects to `index.php` if the user is not logged in.
Note: to show an alert message (success, error, whatever), set the GET argument `msg` to a message ID from `lang/messages.php` .
* pages.php
Define app pages/screens in an array. The page ID/array key is assumed to exist as a file `pages/{key}.php` , or it will 404.
__Optional parameters:__
`'navbar' => true` will show the page as a button in the app menu bar.
`'icon' => '...'` will show an icon from FontAwesome in the menu bar. Setting this to `home` will show the icon `fa-home` .
`'styles' => ["file.css"]` will inject the listed CSS files into the page header (after all other CSS, like Bootstrap).
`'scripts' => ["file.js"]` will inject the listed JavaScript files into the page footer (after jQuery and other builtin scripts).
* langs/messages.php
Array of alert messages.
`"string"` is the language string for the message, `"type"` is one of `success` , `info` , `warning` , or `danger` (i.e. Bootstrap alert classes).
Changing the type changes the icon and color of the alert box.
Setup Tips
----------
* Run composer install (or composer.phar install) to install dependency libraries
* If you don't have any color in the navbar, run `git submodule init` and `git submodule update` .
