difference between create an api using magento
standards and create a php file in the root and
get and send response using simple php code.
is there any security reason we use magento standards ?
any difference in speed of response ?
is there any security reason we use magento standards ?
The standard Magento APIs have been tested significantly more than anything that has yet to be written, so, yes, in terms of security, it's better to avoid writing something custom.
any difference in speed of response ?
Yes, Magento's SOAP APIs are terribly slow. Haven't done much testing with the newer REST API, so I'm not sure if that's any faster.
A third, somewhat obvious, point is that Magento's APIs are already written and can be used on any site out of the box (with minimal configuration). Writing a custom API means that it has to be installed on the site before it can be used.
Also, thinking outside of the box, sometimes it's beneficial to reverse the process. Instead of Foo talking to Magento, let Magento talk to Foo. Of course, this depends on what you're doing, but sometimes this is a much better way of implementing a form of communication between Magento and another system.

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://wordpress.org/extend/ideas/topic/rewrite-wordpress-using-mvc
http://wordpress.org/extend/ideas/topic/wordpress-theme-revamp (more on XSL than MVC)
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.
I'm starting a new project with codeigniter, and I'd like to start on a system that's already built so I can reduce the time of development.
Is there a good system that handles user authentication along with an admin interface to manage users that can be easily expanded to a web-app?
If this is too vague, I can expand
This thread here appears to have some answers
But the question was more about libraries. Either way, implementing some of the things on that thread would save you time.
You're looking for is a Content Management System (CMS).
There are a few ones out there that use Codeigniter as a framework for their CMS.
Edit: Even if you can't find a boilerplate CMS that you like, you can google about CMS's to design a simple one of your own as there's LOTS of tutorials and information about requirements and such when you know the term CMS.
I recommend Redux Auth for CodeIgniter. It comes with an example implementation, and can easily be used to manage user authentication for your CodeIgniter site. I just implemented Beta2 with the latest version of CodeIgniter, so while it's not actively updated, it still works with the latest build.
I'm using Bonfire as default admin interface.
I've just started looking into Bonfire:
Bonfire helps you build CodeIgniter-based PHP web applications even faster, by providing powerful tools and a beautiful interface you won't be ashamed to show your client.
Ready to customize Admin Interface.
User Management with Role-Based Access Control.
Fully Modular codebase.
Built around HMVC.
Database backup, migration, and maintenance.
Powerful, parent/child capable theme engine.
Simple Email Queue to keep your ISP happy.
UI-based module builder.
Looks good at first glance!
The context is that I don't want to use Zend MVC - controllers, helpers, decorators etc - that's overkill for what I am writing.
I've scoured the jQuery site plugins section and these issues bother me most:
I have to search a lot for plugins - it is tedious.
I have to check dependencies with jQuery versions. Thankfully I decided to stick with only jQuery or noConflict() would have driven me crazy.
I have to hook-up all the id's and names of form elements across HTML+CSS+JQuery through Controllers, Views etc.
And all this because there is no other simpler PHP wrapper over jQuery plugins than ZendX_JQuery - and plugins is where the attractive scripts and effects are.
Writing a in-house replacement to ZendX_JQuery will be a huge task in itself. But if you have to wrap third party jQuery plugins in PHP and maintain the thing it is full time job in itself.
So I want to know if Zend_Dojo is much easier than ZendX_JQuery. I'm asking before trying out because I'd have to spend a couple more days installing, configuring and testing all the standard Dojo controls and then I can decide. All that's tedious for a rather simple app which may grow later on.
The alternative would be a "jQuery-inside" PHP widget library that is stable and will work for a year without being broken or upgraded.
Something like GWT or ZK or ASP.Net where you don't have to do low-level HTML+jQuery coding and hand-tweaking for every page with all the ajax controls and form elements.
Or should I just drop an MVC framework altogether and replace it with a custom set of scripts only using Zend components where necessary - like Zend_Validate, Zend_Form etc.
I've been working on desktop apps for some time and the switch to AJAX + MVC + Zend is proving a bit too unwieldy, especially given the abundance of design patterns in Zend MVC.
My recommendation would be to use neither ZendX_JQuery or Zend_Dojo. By the sounds of it, that's overkill for you as well. My thoughts may be coloured by the fact that I don't like to mix PHP and JavaScript code except where absolutely necessary - yes, it may be easier to let a component write your JavaScript for you, but it's never going to be as clean as you could write it yourself.
That way, you also maintain separation between behaviour and presentation - always a good thing, as it makes it easier to use the concepts of progressive enhancement.
I agree with Stephen Orr- I use neither jquery nor dojo (after trying both). I use Zend_Form filters / decorators heavily because client side validation has to be redone on the server side anyway. With some custom decorators, you can do it all in html/php.
I try and avoid ajax where possible, and use prototype / scriptaculous where it cannot be avoided. They are lightweight and provide handy shortcuts to use in other JS code.
Our team is experienced in web development (tomcat/Oracle) but not with AJAX on our existing projects. This is new technology for us, so I want to introduce this carefully and correctly.
What should I look at in terms of frameworks or best practice or common pitfalls?
read this:
progressive enhancement
and use a library such as jQuery, mootools, or YUI it'll save you many headaches with cross-browser implementation. this will show you why you want to use a library.
My first recommendation would be to explore the different frameworks available and see what your team prefers in terms of coding style. Most of the frameworks have the same basic features so a lot of it comes down to preference. I prefer jQuery, so that is my first recommendation, but I worked with YUI, MooTools, Prototype and EXT JS before making my decision.
Secondly, I would recommend working AJAX functionality as a progressive enhancement, allowing your apps to work with and without JavaScript. I find that this approach also ensures a solid, working application before worrying about adding the bells and whistles.
Head First Ajax is a good book IMO for getting started with the basic concepts behind working with Ajax. It would probably be a good place to start for your team to gain some knowledge of what is happening behind the scenes in whatever framework you choose.
One thing we struggled with when starting to use ajax was how often to use it.
We had no exact requirement as to where we were supposed to use ajax and not, and initially we erred to the side of using it too much. This affected application complexity quite a lot.
If you think of your inter-page-structure as a state-machine, ajax introduces nested state-machines within each page-state. The moment your sub-state machine ends up with a number of distinct states (I'd say anything over 2), you should think really hard about using a traditional approach.
The best starting point is to try to get a mix og full page reloads and ajax, and be conservative until you're sure you're getting really good at it.
Don't use it where you don't need it.
Long running operations that need to send the client some status updates? Use AJAX.
Markup for major UI elements (menus, ect)? Use plain old HTML.
Basically, use AJAX for transmitting data only. If you try do fancy things like dynamically pulling in UI elements on the client side with AJAX, you are in for a world of hurt when you get a client who wants to use ie5 (they exist), or a non-pc based browser.
first, look at the user interface you already have, and consider where it might make sense for its elements to be able to change/react independently. This is where your ajax enhancements might make sense
second, look at libraries as noted in the other answers (I like AJAXPRO for its simplicity, but it has been discontinued)
if you find that all of your page elements tie together and cannot change independently, then there is really no need for ajax
otherwise, consider how you will access the page state from your ajax enhancement points - depending on which ajax framework you use, you may or may not have access to the entire page object, session state, original request parms, etc. Consider these issues up front to avoid coding yourself into a hole and/or having to make messy workarounds.
If you were on .Net or Mono I would encourage you to use Ra-Ajax which abstracts away JavaScript completely. Though I work for Ra-Ajax (inventor) so I am biased...
