  1. Alloy Framework PHP 5.3+ Modular Hierarchical MVC http://alloyframework.org Wednesday, March

    30, 2011
  2. Vance Lucas (@vlucas) http://alloyframework.org Who am I? Vance Lucas http://vancelucas.com

    @vlucas Business: http://actridge.com PHP dev since 1999 (PHP 3) I love good OOP code and concepts, but hate the complexity it brings 2 Wednesday, March 30, 2011
  3. A Few Points... Kind of a disclaimer, but not really

    Wednesday, March 30, 2011
  4. Vance Lucas (@vlucas) http://alloyframework.org You May NOT Like Alloy If...

    You are an Object-Oriented Programming Purist You don’t care how complex code is as long as it’s “correct” OOP (because some guy’s book said so) You LOVE using Zend Framework, Symfony, or FLOW3 You LOVE XML and Dependency Injection Containers You are looking for a component library 4 Wednesday, March 30, 2011
  5. Vance Lucas (@vlucas) http://alloyframework.org You MIGHT Like Alloy If... You

    think frameworks like Zend, Symfony, or FLOW3 make some things too difficult and cumbersome You don’t think any PHP framework has it quite right You don’t like “too much magic” You want to know what your framework is doing You value ease of use over everything else You want good OOP code that follows known coding standards that is still easy to use and understand 5 Wednesday, March 30, 2011
  6. Vance Lucas (@vlucas) http://alloyframework.org Philosophy Usefulness, Simplicity and Strong Design

    Minimum code, maximum impact Use OOP principles and design, but don’t over-do it PHP is not Java with dollar signs Explicitness > “Magic” Easier to understand & see what is going on Design patterns should never trump user experience or get in the way Users over “correctness” 6 Wednesday, March 30, 2011
  7. Vance Lucas (@vlucas) http://alloyframework.org Alloy Framework Goals Lightweight Modular Organization

    Hierarchical MVC (HMVC) Easy to understand and use Easy to make REST APIs and HTML pages No config/setup necessary, works anywhere Follow PEAR/Zend Coding Standards Strike a balance between good OOP concepts and ease of use with low learning curve 7 Wednesday, March 30, 2011
  8. Alloy Architecture Inside & Out Wednesday, March 30, 2011

  9. Vance Lucas (@vlucas) http://alloyframework.org Alloy Architecture Overview Modular Organization Kernel

    Plugins Hierarchical MVC (HMVC) Controllers as Resources Events and Filters 9 Wednesday, March 30, 2011
  10. Vance Lucas (@vlucas) http://alloyframework.org Modular Organization All related files in

    a single top-level named folder No separate “controllers”, “models” and “views” directories at same level Unlimited levels of nesting Easier distributable packages 10 Wednesday, March 30, 2011
  11. Vance Lucas (@vlucas) http://alloyframework.org Kernel Core object available from anywhere

    in your app \Kernel() - only global-scope function in Alloy Multiple uses: Config access Lazy-loading Factory / Service Locator Extension Point for Modules and Plugins Sole Dependency 11 Wednesday, March 30, 2011
  12. Vance Lucas (@vlucas) http://alloyframework.org Kernel - Config Access Getter Setter

    12 Wednesday, March 30, 2011
  13. Vance Lucas (@vlucas) http://alloyframework.org Kernel - Lazy-Load Factory Write This:

    Not That: Or This: 13 Wednesday, March 30, 2011
  14. Vance Lucas (@vlucas) http://alloyframework.org Kernel - Extension Point Proxies to

    callbacks added at runtime via __call Enables all kinds of custom functionality Factory methods for loading & using 3rd party libs Exposing plugin methods for global use Helper or utility methods 14 Wednesday, March 30, 2011
  15. Plugins The primary way of extending Alloy Wednesday, March 30,

    2011
  16. Vance Lucas (@vlucas) http://alloyframework.org Plugin - Symfony2 Finder File: app/Plugin/Finder/Plugin.php

    Libs: app/Plugin/Finder/lib/Symfony/Component/ ... Add finder method to Kernel for use 16 Wednesday, March 30, 2011
  17. Vance Lucas (@vlucas) http://alloyframework.org Plugin - Add to Config File:

    app/config/app.php 17 Wednesday, March 30, 2011
  18. Vance Lucas (@vlucas) http://alloyframework.org Plugin - Usage Use finder method

    on Kernel instance 18 Wednesday, March 30, 2011
  19. Hierarchical MVC Solves the “widget problem” Wednesday, March 30, 2011

  20. Vance Lucas (@vlucas) http://alloyframework.org Hierarchical MVC Multiple MVC dispatches to

    fulfill a single request Solves the “widget problem” Sidebar content can be self-contained module Ads, tag clouds, blog headlines, etc. Encourages module re-use & helps DRY Not strictly “hierarchical” - more like nested Hierarchy is not tracked or enforced in any way 20 Wednesday, March 30, 2011
  21. Vance Lucas (@vlucas) http://alloyframework.org 21 Wednesday, March 30, 2011

  22. Vance Lucas (@vlucas) http://alloyframework.org 22 Wednesday, March 30, 2011

  23. Controllers Respond to both internal and external requests Wednesday, March

    30, 2011
  24. Vance Lucas (@vlucas) http://alloyframework.org Controllers Part of the Module package

    that handles requests Special name “scope” for web-accessible actions GET = <action>Action POST, PUT, DELETE, etc = <action>Method Ensures HTTP methods are required for access Alloy\Request object is first parameter All named params from route set on Request object 24 Wednesday, March 30, 2011
  25. Vance Lucas (@vlucas) http://alloyframework.org Controllers (cont’d) NOTHING is automatically or

    implicitly loaded No views, models, or anything else Explicitly return response or content to send Controllers are not factories Controllers are extremely lightweight Controllers do not hold the context of their requests 25 Wednesday, March 30, 2011
  26. Vance Lucas (@vlucas) http://alloyframework.org Example REST Controller Notice <name>Action vs

    <name>Method 26 Wednesday, March 30, 2011
  27. Controller Response Types Sending output and manipulating control flow Wednesday,

    March 30, 2011
  28. Vance Lucas (@vlucas) http://alloyframework.org Simple Strings Sends 200 OK status

    with string content as body 28 Wednesday, March 30, 2011
  29. Vance Lucas (@vlucas) http://alloyframework.org Any object with __toString Sends 200

    OK status with string content as body 29 Wednesday, March 30, 2011
  30. Vance Lucas (@vlucas) http://alloyframework.org View Templates Most common Module response

    type Returns object - template not yet rendered 30 Wednesday, March 30, 2011
  31. Vance Lucas (@vlucas) http://alloyframework.org Resource Objects Auto-converts array to JSON

    or XML for API response Accepts objects with toArray methods 31 Wednesday, March 30, 2011
  32. Vance Lucas (@vlucas) http://alloyframework.org Generic Response Body + HTTP Status

    Base Alloy\Module\Response that view templates and resources extend from Can set custom layout, errors, headers, etc. using a fluent interface just like templates and resources 32 Wednesday, March 30, 2011
  33. Vance Lucas (@vlucas) http://alloyframework.org Boolean False Generic 404 (Throws Alloy\Exception\FileNotFound)

    Plugins can filter on ‘dispatch_exception’ event to produce a custom global response 33 Wednesday, March 30, 2011
  34. Why Explicit Returns? Easier to manipulate responses and control flow

    Wednesday, March 30, 2011
  35. Vance Lucas (@vlucas) http://alloyframework.org Easier to re-use Actions Re-use form

    template from ‘newAction’ No forwarding or other indirection necessary Object return lets you modify it further before display through fluent interface 35 Wednesday, March 30, 2011
  36. Vance Lucas (@vlucas) http://alloyframework.org Modify Dispatches at Will Template object

    returned is not yet rendered so we can modify it at will Change path to a local template Change layout Add errors Change response code or headers, etc. Very flexible 36 Wednesday, March 30, 2011
  37. Vance Lucas (@vlucas) http://alloyframework.org ... Even pull out values Since

    the template is not yet rendered, we can even pull out values that have been set and re-use them however we want to We don’t even have to render the dispatch result at all No wasted resources 37 Wednesday, March 30, 2011
  38. URL Routing Simple named parameters, full control Wednesday, March 30,

    2011
  39. Vance Lucas (@vlucas) http://alloyframework.org Parameter Types <:alpha> Matches [a-zA-Z0-9\_\-\+\%\s]+ <#numeric>

    Matches [0-9]+ <*wildcard> Marches .* Does NOT split the URL by “segment” 39 Wednesday, March 30, 2011
  40. Vance Lucas (@vlucas) http://alloyframework.org Some Default Routes Fluent interface allows

    route modification REST verb params will override defaults and matches POST /module/add => Module::postMethod 40 Wednesday, March 30, 2011
  41. Vance Lucas (@vlucas) http://alloyframework.org Custom Routes Can be literally anything

    URL does not have to map <controller>/<action> Example from Autoridge.com /<#year>/<:make>/<:model> 41 Wednesday, March 30, 2011
  42. Vance Lucas (@vlucas) http://alloyframework.org Static Routes Map arbitrary static path

    to Module::action No PREG matching overhead Path can include slashes and be as long as necessary Router does not split URL into segments 42 Wednesday, March 30, 2011
  43. Making an App HTML + JSON API, single Controller method

    Wednesday, March 30, 2011
  44. Vance Lucas (@vlucas) http://alloyframework.org app/Module/Blog/Post.php Using Spot ORM (Ships with

    Alloy, but NOT required) Spot provided with a plugin, not tied to Alloy in any way 44 Wednesday, March 30, 2011
  45. Vance Lucas (@vlucas) http://alloyframework.org Blog Example app/Module/Blog/Controller.php 45 Wednesday, March

    30, 2011
  46. Vance Lucas (@vlucas) http://alloyframework.org app/Module/Blog/views/index.html.php 46 Wednesday, March 30, 2011

  47. Vance Lucas (@vlucas) http://alloyframework.org http://localhost/path/blog 47 Wednesday, March 30, 2011

  48. Vance Lucas (@vlucas) http://alloyframework.org Magic Datagrid? Alloy has View Generics

    Extensions of view templates Generic HTML template markup with custom functions that accept Closures to enable fully custom PHP markup in designated areas (like table cells) with no special syntax or recursive includes You don’t have to use them, but they can be huge time-savers if you do 48 Wednesday, March 30, 2011
  49. Vance Lucas (@vlucas) http://alloyframework.org Adding an API Template for HTML,

    Resource object for API 49 Wednesday, March 30, 2011
  50. Vance Lucas (@vlucas) http://alloyframework.org http://localhost/path/blog/index.json Array -> JSON via Resource

    response type 50 Wednesday, March 30, 2011
  51. Vance Lucas (@vlucas) http://alloyframework.org API Errors? 51 Wednesday, March 30,

    2011
  52. Vance Lucas (@vlucas) http://alloyframework.org HTML JSON 52 Wednesday, March 30,

    2011
  53. Layouts & Blocks Make your App Look Nice Wednesday, March

    30, 2011
  54. Vance Lucas (@vlucas) http://alloyframework.org Layouts Really just another view template

    with a special location Includes both header & footer, content placed inside 54 Wednesday, March 30, 2011
  55. Vance Lucas (@vlucas) http://alloyframework.org Blocks Named regions that content can

    be pushed to from any view template in your app Static to current request so no data has to be passed 55 Wednesday, March 30, 2011
  56. Vance Lucas (@vlucas) http://alloyframework.org app/layouts/app.html.php 56 Wednesday, March 30, 2011

  57. Vance Lucas (@vlucas) http://alloyframework.org app/Module/Blog/views/viewAction.html.php Post tag list in layout

    sidebar 57 Wednesday, March 30, 2011
  58. Vance Lucas (@vlucas) http://alloyframework.org app/Module/Blog/views/viewAction.html.php HMVC dispatches as “widgetized” content

    Promotes better code re-use, DRY principle, allows polymorphic associations for generic types of content 58 Wednesday, March 30, 2011
  59. Events & Filters Dynamic Behavior & Manipulating Responses Wednesday, March

    30, 2011
  60. Vance Lucas (@vlucas) http://alloyframework.org Layout Plugin Layout wrapping is achieved

    with a plugin in Alloy Filters ‘dispatch_content’ event 60 Wednesday, March 30, 2011
  61. Vance Lucas (@vlucas) http://alloyframework.org Main Dispatch Content Filter Many other

    events and filters not shown in this diagram 61 Wednesday, March 30, 2011
  62. Vance Lucas (@vlucas) http://alloyframework.org Layout Plugin - wrapLayout Returns template

    wrapped in template 62 Wednesday, March 30, 2011
