2. What is WordPress?
3. WordPress is a free and open source blogging tool and a CMS based on PHP and MySQL. Features include a plug-in architecture and a template system. WordPress is used by more than 18.9% of the top 10 million websites as of August 2013. WordPress is the most popular blogging system in use on the Web, at more than 60 million websites. It was first released on May 27, 2003, by its founders, Matt Mullenweg and Mike Little, as a fork of b2/cafelog. As of February 19, 2014, version 3.8 had been downloaded more than 20 million times. WORDPRESS
4. Why WordPress?
5. ✓ CMS standard ✓ So many plugins! ✓ Huge community
6. Lots of freedom!
7. Freedom is good.
8. Some of them want to abuse you Some of them want to be abused FREEDOM
9. Always mix PHP and HTML 1 <div id="content" class="site-content" role="main"> 2 <?php if ( have_posts() ) : ?> 3 <?php /* The loop */ ?> 4 <?php while ( have_posts() ) : the_post(); ?> 5 <?php get_template_part( 'content', get_post_format() ); ?> 6 <?php endwhile; ?> 7 8 <?php twentythirteen_paging_nav(); ?> 9 10 <?php else : ?> 11 <?php get_template_part( 'content', 'none' ); ?> 12 <?php endif; ?> 13 </div> Source: twentythirteen/index.php, line 20
10. You can mix PHP and Javascript... 1 <?php $header_image = get_header_image(); ?> 2 <style type="text/css" id="twentythirteen-admin-header-css"> 3 .appearance_page_custom-header #headimg { 4 border: none; 5 -webkit-box-sizing: border-box; 6 -moz-box-sizing: border-box; 7 box-sizing: border-box; 8 } 9 </style> Source: twentythirteen/custom-header.php, line 143 and you can mix PHP and CSS.
11. Write everything in functions.php Source: twentythirteen ๏ 3 filters ๏ 6 actions ๏ 15 functions ๏ 527 lines
12. Okay, this works.
13. 3 months later...
15. Our story
16. Everyone is different Every client has different needs. Every team has different tools. Every project is unique. It’s very cumbersome to pass a project made by a developer to another developer.
17. Developer Lock-in Theorem A developer can work on a project if and only if he has built it.
18. The problems we had We have a team of 6 developers. That means lot of different people with very different coding styles. We couldn’t move across projects quickly and be agile and dynamic.
19. We needed conventions We needed a more structured organization, a “framework”: always know where to put files and where to find them.
20. A better workflow We want to make projects repeatable and familiar. We like familiar.
21. Style guides, Wikis, Docs ๏ Kind of hard to write ๏ Very easy to forget ๏ Very easy to ignore We needed something else!
22. So we made Wordless.
23. ✓ Default theme structure ✓ Initializers and helpers ✓ Better frontend tools Wordless, a WordPress plugin
24. awesome_theme ├──── index.php ├──── assets │ ├──── fonts │ ├──── images │ ├──── javascripts │ └──── stylesheets ├──── config │ ├──── initializers │ └──── locales └──── theme ├──── assets │ ├──── javascripts │ └──── stylesheets ├──── helpers │ └──── README.mdown └──── views ├──── layouts └──── posts Folder structure Rails tree
25. Why Wordless is good ✓ Every Wordless theme has this same, identical structure ✓ You always know where to find things ✓ Conventions are good <3
26. config/initializers ├──── backend.php ├──── custom_post_types.php ├──── default_hooks.php ├──── hooks.php ├──── login_template.php ├──── menus.php ├──── shortcodes.php ├──── thumbnail_sizes.php └──── wordless_preferences.php Wordless initializers Every customization is isolated in its own file
27. Wordless helpers ✓ link_to, image_tag, video_tag, truncate ✓ placeholder_text, placeholder_image ✓ latest_posts_of_type ✓ latest_posts_of_category Wordless ships with 50+ default helpers:
28. BETTER FRONTEND TOOLS
29. Wordless supports ✓ HAML for writing beautiful HTML ✓ SASS for writing concise CSS ✓ CoffeeScript for writing safer JavaScript
30. Your production server will just use PHP, HTML, CSS and JavaScript. No worries! Wordless automatically compiles all these great languages for you.
31. HAML haml.info A small language which compiles to HTML, which fundamental principle is: “Markup should be beautiful” HAML makes markup templates faster to write and easier to read.
32. <div id="content"> <div class="left column"> <h2>Ciao TCS!</h2> <?php $info = "Siete caldi?"; ?></p> <p><?php echo $info; ?></p> </div> <div class="right column"> <ul> <li class="post highlight"> <img src="one.jpg" /> </li> <li class="post"> <img src="two.jpg" /> </li> <li class="post"> <img src="three.jpg" /> </li> </ul> </div> </div> HTML #content .left.column %h2 Ciao TCS! - $info = "Siete caldi?" %p= $info .right.column %ul %li.post.highlight %img(src="one.jpg") %li.post %img(src="two.jpg") %li.post %img(src="three.jpg") HAML
33. SASS sass-lang.com An extension of CSS3 which compiles to CSS and adds nested rules, variables and mixins. Compass is a SASS framework which adds many mixins for browser compatibility.
34. div.button{ margin: 2em 0; -webkit-box-shadow: 0px 0px 5px #000; -moz-box-shadow: 0px 0px 5px #000; box-shadow: 0px 0px 5px #000; filter: progid: DXImageTransform. Microsoft.Alpha(Opacity=10); opacity: 0.1; } div.button span{ text-align: right; } li{ -webkit-border-radius: 25px; -moz-border-radius: 25px; -ms-border-radius: 25px; -o-border-radius: 25px; border-radius: 25px; font-family: serif; font-weight: bold; font-size: 1.2em; } CSS div.button margin: 2em 0 +box-shadow(#000, 0, 0, 5px) +opacity(0.1) span text-align: right li +border-radius(25px) font: family: serif weight: bold size: 1.2em SASS & Compass
35. CoffeeScript coffeescript.org A little language that compiles to JavaScript, which main motto is: CoffeeScript takes the good parts of it and makes you write better, safer and faster code. “It’s just JavaScript!”
36. var fill = function(container, liquid) { if (container == null){ container = "cup"; } if (liquid == null){ liquid = "coffee"; } return "Filling the " + container + " with " + liquid + "..."; }; var result = [], ingredients = ["coffee", "milk", "syrup", "ice"]; for (i=0; i<ingredients.length; i++) { result.push(fill(ingredients[i])); } JavaScript fill = (container = "cup", liquid = "coffee") -> "Filling the #{container} with #{liquid}..." ingredients = ["coffee", "milk", "syrup", "ice"] result = (fill(elem) for elem in ingredients) CoffeeScript
37. Compiled CoffeeScript var elem, fill, ingredients, result; fill = function(container, liquid) { if (container == null) { container = "cup"; } if (liquid == null) { liquid = "coffee"; } return "Filling the " + container + " with " + liquid + "..."; }; ingredients = ["coffee", "milk", "sugar", "ice"]; result = (function() { var _i, _len, _results; _results = []; for (_i = 0, _len = ingredients.length; _i < _len; _i++) { elem = ingredients[_i]; _results.push(fill(elem)); } return _results; })();
38. Why we use it
39. <?php $the_query = new WP_Query(array('post_type' => 'recipe', 'posts_per_page' => -1)); if ( $the_query->have_posts() ) { while ( $the_query->have_posts() ) : $the_query->the_post(); ?> <h2> <a href="<?php the_permalink() ?>"><?php the_title(); ?></a> </h2> <p class="content" id="recipe-<?php the_ID(); ?>"> <img src="<?php bloginfo('template_url'); ?>/images/flour.jpg" class="alignleft" /> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. </p> <?php endwhile; } else { ?> <h4><?php echo __('No posts found'); ?></h4> <?php } wp_reset_postdata(); ?> WordPress
40. - $the_query = latest_posts_of_type( 'recipe' ) - if ( $the_query->have_posts() ) - while ( $the_query->have_posts() ) - $the_query->the_post() %h2= link_to(get_permalink(), get_the_title()) %p.content(id = "recipe-#{get_the_ID()}") = image_tag('flour.jpg', array('class' => 'alignleft')) = placeholder_text(20) - else %h4= __('No posts found') Wordless
41. Why Wordless ✓ Wordless makes themes familiar ✓ Wordless makes you more productive ✓ Wordless lets you use better tools
43. Wordmove Capistrano for Wordpress
44. To install, test and implement a computer system or application. DEPLOY /dɪˈplɔɪ/
45. ✓ 46% freelancer ✓ 78% uses FTP for deploying ✓ 76% worked live on production ✓ No common approach for database via Smashing Magazine | http://bit.ly/1atrWRp WordPress usage
46. Bad habits Manual tasks
47. Good habits Automation
48. Bad habits No conventions
49. Shared practices Good habits
50. Bad habits Late deploy & Live coding
51. Deploy early, deploy often Good habits
