I´m trying to follow this steps:
https://www.drupal.org/node/2025313
This is my first day in drupal and I have a problem in the first step =(
This:
Identify the file your theme function came from (theme.inc? a core/modules/color/?)
How I can find this "theme function"? I was looking for into a files of the project but I cand find this....
I get this project from other person and I can´t ask him "ey, where is the theme function?" Maybe I have wrong concepts and I don´t know where search...
Can someone help me?
Someone knows what I search? Is a funtcion? Is a file?
So the page you're looking at shows how to convert a tpl.php to a html.twig. This is showing you how to update a Drupal 7 theme to be compatible with Drupal 8.
Assuming that is in fact what you're trying to do, you will normally find Drupal 7 theme templates at sites/all/themes/YOUR_THEME_NAME/templates. Once you navigate there, you should see files ending in tpl.php. Inside these files you might find a theme function being used. You can identify them as they'll look something like function theme_YOUR_THEME_NAME_hook($variables).
What is a theme function?
A theme function is a PHP function that exists to provide HTML that is can be customized by themes and modules.
Here is the official list of theme functions. You can find a lot more information on Drupal.org, but here are a few starter links:
1. Theme API
2. Using the theme layer
3. Theme hooks
I would highly recommend reading a book on theming before tackling anything else. Drupal has a lot of depth, and if you're truly on day one and already converting themes, this will serve you well. I recommend 'Using Drupal' to understand the basics of Drupal, as a lot of Drupal development can be accomplished through the User Interface. Then move onto 'Drupal 7 Development by Example Beginner's Guide' to gain an understanding of how and when you should delve into actual code development.
I am basically a Java/Oracle guy. I was told that it is possible to build any simple Web app with Wordpress.
I successfully installed Wordpress on my machine and am trying to create a text book app. For this purpose, it is an employee database, with fields Name, Address, Department, Designation. I need to have the usual create/edit/search/delete functionality.
The problem with Wordpress is, I really don't know where to start, or how to customize pages.
Am I barking up the wrong tree? Is Wordpress more for blogging/news style websites than for traditional database applications? If not, how do I customize Wordpress to create the application described above?
Thanking you in advance.
Viability
Wordpress is a great system for many different applications, not just blogging/news style websites.
There are many articles out there that go in to great depth on this, but here is a good one right of: http://torquemag.io/app-dev/
Getting Started
As with any project, there clearly is more than one way to skin this cat, but right off, here are some basics I'd recommend you check out about customizing your Wordpress install:
How to create a child theme: http://codex.wordpress.org/Child_Themes
How to create a page template: http://codex.wordpress.org/Page_Templates
How to develop a plugin: http://codex.wordpress.org/Writing_a_Plugin
Plugins
In addition to this, i'd highly recommend a few plugins, which will help make things easy for you:
Advanced Custom Fields
•Makes it really easy to add Custom Fields, to allow you to store custom information, associated with a post, page, taxonomy, user etc. really easy to use, has great documentation and support, as well as a really nice UI. I'd also recommend paying the 25 bucks for the repeater field, which is really useful.
Custom Post Type UI
•Easy way to add custom post types to your wordpress instal, the default post types are: posts, links, pages. With this plugin you can add custom post types for things like say, employees.
Conclusion
In conclusion, I don't think you're barking up the wrong tree, I think that wordpress can be a simple elegant solution for a web application, and can easily be molded into almost anything you can come up with.
For developed such kinds of application you need to develop a wordpress plugins. You can handle any kinds of database operation there. You can add create/edit/search/delete functionality
My sister has a website running on Drupal which i have no experience at all in using. She now wants to edit the design of the frontpage and also so inner but i have no idea how to access the file like "index.html" in a non-Drupal platform.
It has adopted some kind of theme and module (which these two terms puzzled me enough).
May I know how to edit the layout and how to access to the requisite file? thank you...
You are not going to get an answer to your question. Your question is basically 'Tell me how drupal works'. Seems like to need to read up a little on how drupal theme layer works.
It also depends on which theme you are using.
Take a look at: http://drupal.org/node/171194
I am a web Designer that recently decided to expand into developer waters as well :). What I have in mind is to build an elaborate portfolio site that will also contain a blog. The sites sections will be standard for such a project - something like Home, About, Portfolio, Contact and Blog.
The Home page will contain some static parts but also feeds from the latest additions to the portfolio and the blog.
The Portfolio page will have sections on the different types of portfolio pieces (like logo, print, web etc).
The About will be completely static.
The Contact page will be static and will have a contact form.
The Blog page will basically have your standard WordPress blog structure.
At first I was thinking of doing the whole thing in WordPress (since I already have some experience with it) but what got me thinking about different options was the portfolio part. I want the portfolio page to be quite differently stylized than the blog page and yet I want to have the possibility of doing quick and easy additions to it trough an admin panel.
So please give me suggestions and direction about what would be best for me to do? Is this thing possible with WordPress? Should I instead code the whole project with CodeIgniter (or a similar framework)?
I am quite good with HTML & CSS. Comfortable with jQuery. Trying to get better with PHP :).
I am willing to learn and improve and wouldn't mind trying a CMS or a Framework that Ive not had experience with before.
Thank you.
Wordpress is more than sufficient. You might want to find some plugins that allow you to add special content like videos, scripts and other things to portfolio pages. Also knowing html, css well is important if you want to build or modify a theme a lot to your liking. It is also very helpful to know some php if not be very experienced with it. MySql is helpful as well but not as need to know.
This Wordpress PHP function sheet is very helpful at times.
The Wordpress Codex page is also very good. Not an end all be all, you'll still need to know how to do things on your own, but it defiantly will get the ball rolling if want want any custom functions, or want to modify functions.
If you know wordpress a little bit, I hope you will able to make your desired project. Using wp you can do several types of project.
Read some wp books or tutorial and learn wp functions.
Essential wp functions sheet https://codex.wordpress.org/Function_Reference
I hope it will help you.

I'm trying to write out a list of key Drupal competencies, mainly so I can confirm what I know, don't know and don't know I don't know. (Thanks D. Rumsfeld for that quote!)
I think some of these are really broad, for instance there's quite a difference between making a functional theme and creating a theme with good SEO, load times and so on, but I'm hoping you could assume that a half decent web developer would look after that anyway.
Just interested to see what people here feel is also important. I've edited the suggestions so far into this list.
Languages
PHP
MYSQL
Query
Drupal Skills
Research and install modules to meet project requirements
Configure the basic modules and core settings to get a site running
Drush command line tool
Create a custom Theme from scratch which validates with good HTML/CSS.
Able to customise forms, core, themes without altering core files but by using template.php or custom modules.
Can make forms from scratch using the API - with validation and posting back to the DB/email
Can create custom modules from scratch utilising core hooks and module hooks.
Be involved with the community, understand the naming conventions, CVS system and ideally have submitted some code or revisions.
Modules
It's not easy to make a must know module list, as not only is the modules you use very dependent on the site, but also how you use them. However the following are widely used:
Views
Know how to make basic views and blocks.
Know how to make more complex views with relationships and terms.
Know how to use hook_views_query_alter, to make complex queries.
Know how to use hook_views_default_views, to create specific views.
CCK
Know how to setup content - what field types to use.
Know how to create your own field_formatters - the foundation for theming CCK fields.
Hooks
The most important hooks to learn, to create a basic module are probably:
hook_form_alter() - change forms without changing code.
hook_menu()
hook_theme()
hook_nodeapi() - almost anything regarding nodes
hook_schema() - create tables
hook_install() / hook_uninstall() - create tables and clean up.
hook_perm() - when you need special access control.
hook_init() - things to want always to happen.
hook_user() - if you need to tap into user actions or modify the user object.
I good understanding of client-server architecture, how servers and browsers works. And knowledge of php and mysql, templates engines. And of course, you should also read Drupal documentations.
Able to create a custom Theme from scratch which validates with good HTML/CSS and also pays attention to usability and accessibility. (Whilst still looking kick-ass).
You usually don't want to create themes from scratch but from a starter theme like Zen instead.
For Drupal you will need:
PHP, it's a PHP framework, so to really understand and use it, you need to understand PHP.
SQL, the list of SQL serves that Drupal can use is growing, but you will need to understand * SQL, relational database and how to setup some basic architecture.
Javascript (and jQuery). Drupal uses the jQuery js library, so it will be a lot easier if you not only, know how yo use javascript, but also understand how to use jQuery and some of it concepts.
The hook system and how you can alter Drupal core and modules implementing hooks.
The naming convention for hooks, theme functions etc.
Modules
It's not easy to make a must know module list, as not only is the modules you use very dependent on the site, but also how you use them. The two top modules in Drupal is.
Views
Know how to make basic views and blocks.
Know how to make more complex views with relationships and terms.
Know how to use hook_views_query_alter, to make complex queries.
Know how to use hook_views_default_views, to create specific views.
CCK
Know how to setup content - what field types to use.
Know how to create your own field_formatters - the foundation for theming CCK fields.
Another module that I find very powerfull once mastered is Panels. It allows you to do a lot of complex and difficult things with very little and simple code. There is a lot of hooks you need to learn, and not much documentation. But once you understand Panels, you find that you time has been well spent.
Hooks
The most important hooks to learn, to create a basic module is probably:
hook_form_alter() - change forms without changing code.
hook_menu()
hook_theme()
hook_nodeapi() - almost anything regarding nodes
hook_schema() - create tables
hook_install() / hook_uninstall() - create tables and clean up.
hook_perm() - when you need special access control.
hook_init() - things to want always to happen.
hook_user() - if you need to tap into user actions or modify the user object.
You don't need to use all of these hooks all of the time, but they are some of the most used ones.
Great list so far! Some others for consideration:
Ability to use Drush to update or setup a site
Strong understanding of good best practices configuration for performance, security and SEO of a Drupal site (think launch checklists)
Having submitted a module to Drupal.org (however simple) or submitted a patch (the process of getting a CVS account and getting your first code in is instructive to the community and to standards)
You don't need SEO skills for templates, drupal usually helps with SEO alot. Ofcourse a developer who will slice a design must know that all headings must be done with h1,h2,h3,h4 tags. that's really basic one. everything all is up to drupal..
as for my opinion to be a drupal "developer", you need some very basic skills in PHP. Because drupal is really written without object-oriented programing, and without DESIGN PATTERNS, so these are two things is really makes you a programmer.. without them it just [sorry for this word] bullshit not a programming.
I think anybody can install drupal or wordpress or some cms-made-simple, systems if you have at least once connected to ftp in your life... to develop plugins for them is a requires basic skills of php. Ofcourse if you'll find skillfull developer then he will know oop basic, and will write plugins with OOP and that code will be really NiCE! =)
Being able to edit existing functionality (core or module) without touching the core or module and knowing whether to put it in template or a custom module.
As we anything web related these days, you really must have a good understanding of the HTTP protocol. You also need a good understanding of JavaScript, the DOM, CSS and HTML5. Knowing a bit of jQuery is not enough for a developer, you need to understand what your are doing with the DOM, HTML5 APIs and CSS in order to build features and behaviours into the browser. You also need to understand the Drupal JavaScript APIs, both on the server side (hook_library(), #attached, etc.) and the client side (Drupal.behaviors, etc.)
You also need to known the various APIs of Drupal. The Form API is not the only one. You need to understand the Menu system (page, access, title and delivery callbacks, how to pass parameters to them, etc.), the Queue API for asynchronous operations, Batch API for long running operations, Entities and Field APIs for user editable structured data, Theme API and Render Arrays for anything presentation, Cache API, Schema and Database APIs, File API, Cache API and the Localization API.
