Using codeigniter 2. Don't want to reinvent the wheel. Have tried Grocery_CRUD and found it takes as long, or longer, to learn it that it did to learn codeigniter.
Looking for crud library that makes sense, easy to learn so I don't reinvent the wheel.
Many thanks for any ideas.
You can use http://www.grocerycrud.com
It's easy to use with codeigniter.
Sample use
$this->grocery_crud->set_table('customers');
$this->grocery_crud->columns('customerName','phone','addressLine1','creditLimit');
$this->grocery_crud->render();
Also you can take look at https://github.com/jamierumbelow/codeigniter-base-model
This is very basic base model class for CI
Subjective but take a look at https://github.com/keevitaja/simple-crud-codeigniter
Why don't you try MY_Model to do all the CRUD functionality?
MY_Model
Just want to inform all you that I have released CRUDDER. This is a plug-in module for your application that works as a CRUD solution, ideal for systems back-ends.
CRUDDER is developed using CodeIgniter and Bootstrap for look&feel. You can develop your own skin appart from the Bootstrapped one. Full localization is possible. CRUDDER is designed to be intuitive and easy to use. The interfaces always show on-line help tips related to the CRUDDER itself and also to your database characteristics.
I'm attaching here an image of the CRUDDER example contained in the product web page so you can figure how easy it's to use.
On the other hand, you will find that configuration is very easy. There is no need to write code other than your own custom validation rules (more powerful than the CodeIgniter ones). There are only two classes: one contains all the functionality code and the other, Crudderconfig, encapsulates the configuration and localization parameters.
In contrast to other commonly used open-source CRUD solutions available, in CRUDDER all the table-and-field-specific metadata don't require to write code. All of this is contained in two "metatables", that can also be managed using the CRUDDER itself... so you use the CRUDDER to create your own CRUD rules (don't need to use phpMyAdmin, for example). This is a plus for users seeking for simplicity.
A full list of features is available:
Open the project web page
Among them:
Pluggable to applications not developed with CodeIgniter.
Sort, filter and pagination features, among others.
Soft deletes with unique-index collision avoidance.
Automatic menu-type form fields based on other tables content.
Extensible event triggering when a value is changed in a form.
Interface help tips for fields are contained in the database.
Designed with strong security in mind.
Take a look! Write me if you like it, have questions or want another functionality.
CRUDDER is released under the GNU LGPL license.

I realise this might be a little vague but I honestly don't know where else to ask. I have some history with PHP and I am trying to teach myself ASP.NET MVC3.
While I can find a LOT of source material on syntax and tutorials on various parts. I've started it off and I've got quite a bit going but I'm finding it a bit difficult to figure out exactly how to design the whole thing with regards to where to put things and I'm not entirely certain who I can ask or where I can find these things out?
The project I'm working on, in an attempt to teach myself is a form of online rpg game site. I've got user registration and log in, I wrote a custom membership provider to fit that to my existing database structure. But the trouble I'm having knowing where to do database lookups and how to store data etc. For example, let's say you log in, you have a certain amount of gold. On the right side of the status bar on the _layout page it will always display this value. Where do you look this up? How do you remember it? In the controller? Which controller? Etc etc.
Can anyone maybe recommend either a good set of advanced tutorials or some kind of forum where this can be discussed?
Thanks!
I learned everything i know from:

Those are all good links and tutorials. In addition, you are going to want to have a separate database for your data vs. your Authentication and Authorization. This will allow decoupling and better security. You should be storing data in a database, and then the model will hold access to that database through a DAL (Data Access Layer) usually with the controller holding an instantiated repository of the DAL. In this sense the controller can build objects from the model (and thereby from the database) and then send them to the view through strongly typed objects for you to use in a User Interface.
Nerd Dinner is a pretty good sample of the whole picture, you can download the sample code and play with it.

The problem I find is a lot of examples don't use best practices for MVC in favour of simplicity and ease of reading in tutorials. So I'll outline some of the things I've found out the hard way and that work for me.
Personally from what I've found is your controller should be responsible for handling information via ViewModels to act as Data Transfer Objects (DTOs) between your business logic and your views, and that's all they should have in them. I choose to never have business logic in the controller and instead opt for a series of service classes designed to deal with their own group of responsibilities (IoC takes care of most concerns the Services may have).
This is done to keep the business logic DRY and to make it easier should you decide to try making a mobile version of your site later, or maybe expose a public WebService/API to your data.
The views should each use ViewModels specifically meant for each view, and these views should ONLY consist of primitive types or other view models. Never use a data entity from your ORM directly, though I'll be honest I have been known to break my own rule on this when it comes to views that only display information, but I usually pay for it later. Validation rules imposed on your data model are not necessarily applicable to a form and data loaded on your entity may not be relevant to your view either. ORM's that support Lazy Loading complex data entities can cause havoc with some VERY useful 3rd party libraries you can use in MVC like MiniProfiler and Glimpse, not to mention other issues when it comes to rendering these objects in forms for posting back later. So try to stick to flat ViewModels if possible.
I typically name my ViewModels according to their use. so my Register page may use a model called AccountsRegisterViewModel. However when I postback I usually use a different model called AccountsRegisterFormModel. This is because many times there is information I need to pass to render in the view but I really don't care about it (nor will it be present in most cases) on the action that accepts my postback. Also, MVC requires you to disambiguate your actions that use the same name via different parameters so using different view models helps there. For example CreateAccount() to show the account creation page and CreateAccount() that accepts your submission from the form. Though you can explicitly change where each form posts, the main focus with MVC is convention over configuration so I try not to change where forms post back to.
For your specific example of showing relevant information (Gold balance) you're likely going to want to create a Child Action with it's own view that would be responsible for doing it's own data access, or if you want to try your hand at ajax, have the balance be something handled in a smiple partial view that makes a call to a public action that returns JSON.
Those are the practices I've found have worked for me so far.
For ages, our company uses Dojo as the interface library of choice. The applications created have a very desktop-like look & feel and are very suitable for business areas and banking.
However, I see a trend towards user interfaces that are more like Google+:
page-based instead of internal scrolling
not many modal popup windows but rather edit-in-place and drop-out things
loading additional list items via scrolling to the bottom of the page
all that kind of user interaction. Basically, a light and more web-centric usability approach.
Unfortunatelly, I don't know of an library that really helps in building such interfaces - I know jQuery UI, Sencha, Cappucino, Sproutcore and the like, but they do not quite fit.
Does anybody know of some new ui component library for sites like Google+?
A lot of the interface patterns used in Google+ are in Google Closure Library.
You can use the following book about Google closure : Closure: The Definitive Guide for reference.

Having been dropped into ASP.NET MVC 3 with no guidance but the web (2 books on order), I can't even get off the ground.
The MVC itself I get. Not a problem.
PHP, Ruby, and even ghastly WebForms firmly tucked into my toolbelt, with a long history of C++ QT client-server development before that.
Tying ASP.NET MVC 3 to a database using EF4 ORM is killing me.
The goals:
Use database modeled by DBA. I can specify all naming conventions, but code first is not an option!
Import to EDMX. This will be regularly updated using VS tools from the DBA's DB, never edited directly.
Generate partial classes from EDMX, for use as model. This will regularly be updated using VS tools, never edited directly.
Use 'buddy' to extend above model class with code as the Controllers/Views need.
Intuitively use the resulting model, pass it to the view, retrieve posts into it for insert/save, etc...
I've seen and read so many blogs, forum posts, walkthroughs, and stack overflow posts regarding this very use case.
I even tried riding the magic unicorn, followed by the latest 4.2beta1 with DbContext generators.
But can't get off the ground.
I follow instructions, but just not understanding how to do anything with it.
What conventions does the 'buddy' require (if any)? How do I use it? How do I get data with it? How do I write data?
Every example looks different. MVC guides are always focused on the UI side. EF guides don't cover usage in the MVC.
These are basic questions, and I'm feeling like the most incompetent idiot in the WWW right now.
Is anyone out there currently using MVC3 & EF4.x in the way I describe above?
This video is a good starting resource. Its a video of a guy creating an app from scratch that uses entity and a sql database (though he makes the db in the video, its still good for seeing some basics in action). You can see how he pulls data from the database, displays it on the page, and saves changes back to the database.
The first question I would ask is why are you stuck on using EF as an ORM or even insisting an ORM at all? I'd choose tools to suit the job here, especially given the constraints of the data layer.
Buddy classes were a concept invented in a day when the main .NET ORMs had no code-first option as ORM-encumbered class instances really don't behave well under things like model binding. Nevermind you could not decorate them with the DataAnnotations one used to indicate fields were required. Typically, the technical requirement is to use [MetadataType] attributes to tie your buddies to your models and perhaps something like AutoMapper to map data to and fro.
All that said, as a guy who has a few apps with lots of buddies and lots of automapping going on, you might want to think otherwise -- it is a bit of a maintenance nightmare. I'm living it.
There are some really good getting-started videos and tutorials right on ASP.NET MVC's site. The "Model (Data)" section is Entity Framework focused and touches on hot/trending topics like Repositories and Units Of Work.

Some people consider WordPress a blogging platform, some think of it as a CMS, some refer to WordPress as a development framework. Whichever it is, the question still remains. Is WordPress MVC compliant?
I've read the forums and somebody asked about MVC about three years ago. There were some positive answers, and some negative ones. While nobody knows exactly what MVC is and everybody thinks of it in their own way, there's still a general concept that's present in all the discussions.
I have little experience with MVC frameworks and there doesn't seem to be anything about the framework itself. Most of the MVC is done by the programmer, am I right? Now, going back to WordPress, could we consider the core rewrite engine (WP_Rewrite) the controller? Queries & plugin logic as the model? And themes as the view? Or am I getting it all wrong?
Thanks ;)
Wordpress itself is not architected in MVC, but one can build very MVC oriented themes and plugins within the framework. There are several tools which can help:

http://core.trac.wordpress.org/ticket/12354 (on MVC in widgets)
Wordpress is kinda-sorta MVC. If anything it is a pull-type MVC layout, where the View 'pulls' data from the model. It does this in a very proceedural way, instead of using lots of different objects, but this actually makes the front end templates easier to write in a lot of ways.
This also gives the views some degree of controller logic (thus the kinda-sorta MVC).
Lets run this down:
Wordpress gets a URL. The wordpress core acts as a controller and determines what initial queries to run of the database, and by extension, what view should be loaded (category view, single post or page view, etc). It then packages that INTIAL query response and sends it to the view file.
That view file CAN be a strict display only file OR it can request additional information/queries beyond the built in one. This is the pull-type of the MVC, where the view pulls data from the model instead of the controller 'pushing' data from the model into the view.
Thus, when the view sees code to load a sidebar or widget area, it asks for that information. However, what widgets should be there is determined by the controller, which looks at the model for what widgets are in the sidebar, and then selects those that are set to show on the current page, and returns those to the view.
That each part of that isn't an object doesn't make this any less MVC. You can alter WP core without (necessarily) altering anything about a theme. Similarly, as long as you use built in functions like 'get_pages()' then the model and the database tables could change as long as those functions still returned the right data. So, the model is independent of the view, and the controller is independent as well (except when the view adds controller logic to do more than the core normally does).
While you COULD have a model object holding a number of methods and stuff like WPModel::get_pages('blah blah'), and contain everything that way, there is still fundamental separation of concerns.
View: template files
Controller: WP core
Model: the various functions that handle specific data handling.
As long as the names, arguments, etc, stay the same (or just have new ones added) then separation of concerns is maintained and one can be altered without disturbing the others.
It isn't a super-clean version of MVC, (especially when hooks get involved), but at a basic level it starts there.
And being proceedural about it isn't a bad thing IMO. A request from a website is pretty inherently proceedural: it is a process with a clear beginning and end, and just needs a procedure to process the request, get data, package it, then die. You can set up those steps with objects and object methods and OOP layouts (which would make some things easier) or you can just write alot of function calls and separate them out that way. Class members like private variables are lost that way but depending on the needs of the application... you might not care.
There is no one-grand-way to do development, and WP sits at like 20% of websites so it is doing something right. Probably something to do with not making people have to learn/memorize complex class hierarchies to get the database to answer the question 'what pages are child of page x?' and deal with that data. Could you make it that easy with OOP? yes, but if Joomla is any example of how hard it is to implement a complex custom website with OOP, then WP is FAR easier and quicker, and time is money.
As already mentioned in the comments, MVC is an architectural design pattern, not a specific framework, and no, Wordpress doesn't follow the MVC pattern.
There is a separation of views (templates) from the programming logic, but only in the frontend, not in the admin panel and a general separation of views and application logic is not inevitably MVC. An implementation of the MVC pattern usually assumes some kind of object oriented programming paradigm behind it and Wordpress is mainly implemented in a procedural way, with plain SQL queries in the PHP functions, therefore not having an actual model either.
One of the topics that periodically crops up in discussions as it relates to WordPress is the idea of WordPress and MVC.
But the thing is that MVC is not the silver bullet of web development that we try to make it out to be. Yes, it’s an awesome design pattern, and I personally think that it fits the web application model like a glove, but not every framework or platform implements that design pattern.
Case in point: WordPress is not MVC.
And that’s okay. I think we need to leave the desire of trying to shoehorn it into our projects aside especially when the pattern WordPress provides is not only sufficient, but works well when leveraged correctly.
“But I Love MVC!”
So do I! In fact, I spent the last year working on a project that more-or-less mimicked the MVC architecture.
A high-level example of MVC.
A high-level example of MVC.
For example:
Views were implemented using templates
Controllers were implemented by a combination of using function names like create, read, update, destroy, delete, and so on (even though these functions were hooked into the WordPress API
Models were functions also were called to validate and verify data prior to serializing the data. Again, this required that certain functions be hooked into WordPress to achieve the desired result.
Finally, a set of rewrite rules gave the application a clean set of predictable URLs in the format of /people/update/1 or /people/all.
What Pattern Does WordPress Implement?
WordPress implements the event-driven architecture (of which there are several variations such as the Observer Pattern).
In short, you can conceptually think of this as the following:
Things happen when WordPress is processing information.
You can register your own function to fire when these things happen.
Not too complicated, is it?
A high-level example of event-driven patterns
A high-level example of event-driven patterns
When you begin to think in terms of the paradigm in which it works rather than trying to make it work the way that you want it to work, it’s liberating. It helps to solve problems much more easily.
The bottom line is this: WordPress implements the event-driven design pattern, so even if you end up trying to implement MVC, you’re still going to have to utilize the hook system.
If you’re not careful, you can end up trying to craft the perfect architecture without actually getting your work done, and thus end up finding yourself so high up in the atmosphere of software that you’ve effectively become an architecture astronaut.
So You’re Saying Avoid Design Patterns?
Not at all! Design Patterns serve a purpose because, above all else, they basically give us solutions to previously and commonly solved problems. Use them!
But the point I’m trying to make is that we don’t need to try to force things to fit pattern just because we like the pattern. That’s not their purpose. Instead, leverage the primary pattern that your platform of choice implements – in our case, it’s an event-driven pattern – and then implement patterns where they fit (such as dependency injection or something like that).
Otherwise, it’s like trying to put your foot in a glove.

Just to update this with more recent information for people hitting this from search engines - the wp-mvc plugin http://wordpress.org/extend/plugins/wp-mvc/ goes a long way to creating a mvc framework for plugin development. You can find out more here: http://wpmvc.org/documentation/70/tutorial/
Just to add to the list of options, (I'm admittedly biased as the author,) swpMVC is a fully featured, lightweight MVC framework, inspired by Rails, Sinatra, Express, and FuelPHP. It's thoroughly documented, and while I have used and enjoyed wp-mvc, I wanted something where the models were able to populate views themselves, including form controls for interacting with said models.
I put this together largely to reduce the amount of controller code required to put together an app on top of WordPress, and the result is a very fast and effective framework that runs inside WordPress. The models are based on PHP Activerecord and 8 models are included for existing WordPress data types, including Post, PostMeta, User, UserMeta, Term, and a few more. Modeling data is very easy thanks to the activerecord library, and I've enjoyed working with this framework immensely thus far.
Also ships with underscore PHP and PHP Quick Profiler (as seen in FuelPHP.)
RokkoMVC is a micro MVC framework built especially for WordPress. The project is meant to simplify AJAX functionality in WordPress applications, as well as bringing in all the other benefits of using models, views, and controllers to your theme.
I had a bash recently at creating a plugin that makes use of a simple view-controller system, and quite liked the results, so I separated the template stuff out to its own repo. It offers object-based controllers, passing variables locally to PHP templates, template fragments (templates within templates) and components (template fragments with their own sub-controller). All in two tiny classes!
Of course, I wrote this code thinking that no other WP developer had considered the problem before ;-).
It's far from mvc, there is no kinda-sorta thing like some people say, it's either MVC or not... The fact that you write logic on the view level doesn't qualify it as a mvc framework. The reason people use it - it's easy to learn, you don't need to be hardcore php programmer, they're lazy.
