usually its done by setting up the config.xml but what to do when my component needs more parameters at run-time ? There is little or zero information about, just 1-2 tutorials about custom parameters which could be used to archive the same thing but only if you're willing to write lots of bloat code for a very simple thing.
In my case my component is rather a little platform in it self, ie: users can add plugins from us. Of course I'd like to expose some options for such plugins in the component's options.
Is there any shortcut because if you look at the built-in component's code, you really don't want to do the same for each plugin...
well, thanks! any thoughts are welcome!
ps: may be there is something more compact like the Redux-Framework for Wordpress. I'd love to know there is library which can server both CMS systems.

'component' = Joomla component and by 'plugin' I mean my and non-Joomla plugin, hosted in a Joomla component. Imagine your Joomla component is just a host for external plugins.
You need to create a custom field type, where you'll be able to implement all the logic that's needed.
In case you need to store the values with the component, add a hidden input field, and use javascript to populate the markup on load, and insert the values you want to store on user interaction (you can also store an object encoded in json). Joomla will take care of saving and retrieving it.
the docs
I wrote a plugin for joomla that adds custom fields to the user/register component. There are 3 different registration forms for different user groups.
The plugin acts on onUserAfterSave() and works fine, but there is one problem. When there is an error in the original user component, for example: "the username has already been taken" the form is redirected and neither onUserAfterSave() or onUserBeforeSave() is ever called.
I want to change that redirection, but without changing the core, but since neither plugin events are called, im not sure how to. Can you guys help me? Maybe I am missing something!
Is it possible to maybe override the save() function?
THANKS
I had same problem many times, so i can share a solution i use myself. If you don't want to edit Joomla core files, you can do the following:
Create your own template override of registration view.
Duplicate the components/com_users/controllers/registration.php file and lets say name it registration2.php
In your registration form override change hidden input's "task" value from registration.register to registration2.register
Feel free to override registration2.php classes how you like.
It's totally Joomla update proof, so you can update your joomla version witht worrying about errors.
I think you might need to do the checks that joomla is doing in your plugin and redirect in your plugin itself in the case that it wont pass. I see your predicament and I don't know a better way but I would pick a different event to run it on maybe even after page load and then on UI event in javascript.
The only clean way to extend the user registration/profile is to create a profile plugin like this one
https://github.com/joomla/joomla-cms/blob/master/plugins/user/profile/profile.php
You can extend com_users forms in backend and frontend.
I am looking for a more advanced user agent detection library for Codeigniter.
I want to add short tags for OS, Browser and Browser version to the body tag so
that I am able to write CSS that is gear towards different browsers and platforms.
Like this:
<body id="Win7 IE9">
Right now the default agent detection library for CI produces this:
<body id="Windows 7 Internet Explorer 9.22.2">
How can I "shorten" the response?
This is want I am looking to achieve: http://www.contao.org/en/blog/forget-about-browser-hacks-in-contao-210.html
Thankful for all input!
I don't think that user agent library is bad. It just do what it is supposed to do.
Maybe you should build a small helper or extend the user agent library, this is really simple task (you should look at agent->browser(), agent->version, agent->platfrom() etc.)
Despite what Contao says, these are browser hacks. Better way is to build your style sheets and/or javascript the right way (without this type of hacks). I don't ever needed different stylesheets (or browser specific classes) for different browsers.
I see what you are trying to do. To get away with this using CodeIgniter you'll have to basically rewrite the user agent library to return your shorter user agent strings (its time consuming but not too difficult)(the four user agent arrays are in: system/libraries/user_agents.php).
Its been more than a year since this question was asked but i am sure it will help someone in future. User agents names are defined in ./application/config/user_agents.php file in an associative array format you can change the value of array with the one you want.
Note: Changing the value in config file will reflect in the entire application. If you want to change in a particular area of application i would suggest to create your own function.
Try this
$this->session->userdata['user_agent'];
So I dont know what it is called but I am looking for a way to box in the user entered email addresses like they do in hotmail, where any valid email is boxed into that rectangle locked email once it is validated in real time? Also in hotmail they allow you to remove it by clicking the X and edit it by clicking the edit icon. I want to add more features also appart from edit and delete, so I guess I use AJAX for this? I dont know the term for this so not sure how to search for sample code and design patters for this. Any idea on what this is called or sample links with different design patterns?
You mean a facebook-like autocompletion? It uses AJAX (Javascript libraries: Prototype / Scriptacoulous).
Maybe this library is not perfectly suited to your use case, but you definitely need Javascript to do it as soon as the user enters it, but not necessarily AJAX - via javascript you can create input-hidden fields that will get submitted with the rest of the form.
I want to create my own form that are submitted and values of that form will be stored in joomla database. How can i used the Joomla connection code to interacte with the joomla database.
If you just want to get your work done, there are some components already avaiable in Joomla Extension's website to your form's needs. CkForms is a good one, you can create simple forms with it that are automatically saved in the database (supports upload of files too).
If you want to learn how to write extensions in Joomla, you should read Joomla Official Documentation website.
Extensions in Joomla are divided in "Components", "Modules" and "Plugins". More informations about these differences can be found here and here.
What you're trying to achieve sounds a "component" to me. Downloading the CkForms and reading it's source code should get you started to Joomla's way of writing components.
EDIT: Joomla has a huge API with a lot of features. It has a database module of it's own, with insert methods and such. Reading Joomla's API website before implementing your component it's a good idea to avoid "reinventing the wheel" and it's a good practice since those methods are extensively tested by all Joomla users.
The JForm class helps you build forms.
Documentation can be found here:
joomla CMS: http://docs.joomla.org/API16:JForm
joomla API: http://api.joomla.org/11.4/Joomla-Platform/Form/JForm.html
This class provides you with ready to use form elements and form loading and/or processing methods
This class includes validation methods, date picker control, color picker, etc.
Of course, as another mentioned above, if you are building a module, component, or application, you will need to learn how to to develop a module, component or application. Of these three, the module is the easiest to implement.
The application gives you much freedom b/c you are not constrained to the CMS paradigm, front and back end complexities. However, there is little documentation about how to develop applications with Joomla framework b/c joomla as a framework is relatively new
This tutorial gets you started understanding how to use JForm to create a form in Joomla: http://www.ostraining.com/blog/how-tos/development/getting-started-with-jform/
Or you could just create add a html module to any position and then write the form in html i.e.
<form method="post" action="mycreatedpage.php"> <input type="text"/> <input type="submit">
Now just create a page that handles the code by emailing or inserting into db. I havent tried it but i think it should work.
Looks like everyone already told you almost everything I know except for the component creator. Very easy to use, and it follows Joomla standards. Will get you up and running within minutes.
I have got good working experience with Joomla RSForm Pro. It has got options for
validation
user email/admin emails on submit
file uploads
and many more
Good tutorials too. Get started with http://www.rsjoomla.com/support/documentation/view-knowledgebase/21-rsform-pro.html
Good luck!
Create View.
Create Model.
Create Table.
Create Controller ( if Needed ).
Create Form xml file.
Go here for more information:

Take a look at the Chronoforms extension - does more than you want.
You have two options:
Use an already built custom form extension
Create your own custom form extension (or outsource it)
Now if you only want to modify the user registration form, then you can do some PHP customization to accomplish your goal.
Making forms in Joomla can be done in a couple of ways.
If you just wanted a contact us, you can just create a page with a menu item for the User contact form. This gives you a page with a Members address and contact form. So all you would need to do was add the user as the company of the websites home address and email. But the form is very basic, name, title, textarea for message.
Next up from that you could just make a Custom HTML module add add a form to it in plain HTML like +Sean said above this, you would need to code in PHP your own form process script. You would not get error in form data checking unless you also wrote it.
Next you might rather look on the Joomla Extension Directory JED for one of the good extensions for 3 and 2.5 Joomla RSForms!Pro is good, and can do all we have needed. This lets you add fields one by one and move your form around. Then can auto generate or custom the html of the form.
You can easily create your own forms with Fabrik
Chronoforms are now a days a very popular solution for custom forms in joomla. Chornoforms support twitter bootstrap also. In simple 5 steps you can create a contact form with unlimited fields and also embed various function like DB save, Email, Thanks Message, Redirection on any page. There is events and events will have particular events.
Also possibility of extension of Normal joomla registeration. It will not extend the core registration but at the time of registration you can take various information from users.
I would use Chrono Forms, they work really well and are easy to use.

You can use plugin to insert external php form in content. It is easy and you don't need to make plugin etc. Please use this.
I suggest you to use breezingforms: http://crosstec.de/en/extensions/joomla-forms-download.html
It's one of the best solutions for custom form creation in joomla.
