I figured out how to pass one.. but how do I pass multiple GET variables from a FORM?
This is the most repeated question of all time in CodeIgniter, second only to "How do I remove index.php".
How can I use GET forms with CodeIgniter?
Google is your friend.
sending data from get is really a hassle so i suggest u to use post data instead. its easy and safe.

I'm new to backend programming. I chose the laravel framework. Already learned the basics. During the study, the question arose: is it necessary to use the form to transfer data to the server ?. For example: the deletion route looks like this to me
Delete.
If I leave it, will it be a mistake? Maybe advise an article or something. Thanks in advance
Short answer is no, it's not necessary, but you should (if you're bound to HTML only).
The HTTP standard has different methods for different purposes. Using an anchor tag will always make a HTTP GET request to the link/server, which is not ideal, GET request should never change the remote (server) state, that's a job other methods (POST, PUT, DELETE, PATCH), you should try to use the method that better describe what you're trying to do: in your case I suppose you're trying to delete a complaint, so a DELETE or POST is what you're looking for.
The only way to use make a non GET request in plain HTML* is to use <form>. Also if you're planning to use a method different from POST you should take a look at Laravel's #method here
Mind that if you can and want to use JavaScript to perform your request you totally can, dropping the requirement to have use form (docs and docs).
I need to convert any string without GET parameters:
www.mysite.com/?a=5&s=5 ---> www.mysite.com/
www.mysite.com/books/?bla=blabla&bla=4 ---> www.mysite.com/books/
I need to hide $_GET parameters.
I cant use POST parameters.
How can i do this ?
Then use POST.
POST-Data is not visible in the url and can be used like GET, but has to be pushed from a HTML-Form or something
Variables submitted by the method GET go in the URL, so it's impossible to hide them. However, you can make them prettier using the MVC architectural pattern. It's a more sofisticate solution that really pays off, in terms of organization.
For example, URLs like mysite.com/?a=5&s=5 would become mysite.com/5/5
You used $_GET[], so I assume you're using PHP. Take a look at Laravel or Phalcon.
In case you do not want to show any of the variables, you have to use POST. Data submitted by POST is inserted in the body of the HTTP request. Please, keep in mind that the body will not be encrypted, unless you use HTTPS.
I am struggling to understand something that I am sure one of you will be able to easily explain. I am somewhat new to MVC so please bear with me.
I have created a controller that handles all of the work involved with connecting to the Twitter API and processing the returned JSON into HTML.
Route::get('/about', 'TwitterController#getTweets');
I then use:
return View::make('templates.about', array('twitter_html' => $twitter_html ))
Within my controller to pass the generated HTML to my view and everything works well.
My issue is that I have multiple pages that I use to display a different Twitter user's tweets on each page. What I would like to do is pass my controller an array of values (twitter handles) which it would then use in the API call. What I do not want to have to do is have a different Controller for each user group. If I set $twitter_user_ids within my Controller I can use that array to pull the tweets, but I want to set the array and pass it into the Controller somehow. I would think there would be something like
Route::get('/about', 'TwitterController#getTweets('twitter_id')');
But that last doesn't work.
I believe that my issue is related to variable scope somehow, but I could be way off.
Am I going down the wrong track here? How do I pass my Controllers different sets of data to produce different results?
EDIT - More Info
Markus suggested using Route Parameters, but I'm not sure that will work with what I am going for. Here is my specific use case.
I have an about page that will pull my tweets from Twitters API and display them on the page.
I also have a "Tweets" page that will pull the most recent tweets from several developers accounts and display them.
In both cases I have $twitter_user_ids = array() with different values in the array.
The controller that I have built takes that array of usernames and accesses the API and generates HTML which is passed to my view.
Because I am working with an array (the second of which is a large array), I don't think that Route Parameters will work.
Thanks again for the help. I couldn't do it without you all!
First of all, here's a quick tip:
Instead of
return View::make('templates.about', array('twitter_html' => $twitter_html ))
...use
return View::make('templates.about', compact('twitter_html'))
This creates the $twitter_html automatically for you. Check it out in the PHP Manual.
Now to your problem:
You did the route part wrong. Try:
Route::get('/about/{twitter_id}', 'TwitterController#getTweets');
This passes the twitter_id param to your getTweets function.
Check out the Laravel Docs: http://laravel.com/docs/routing#route-parameters
I've a situation where i get some information from database and based on the data , i want to do/forward to some other controller & action.
How can i do this using Yii? Its like an ajax request..
If i can use the CController->forward() , then how can use the post values for actions?
I shall assume that the reason why redirect() didn't work for you was because you can't sent post variables with it. If that's the case, then let me show you how to overcome the lack of POST support in redirect(). You can use setState(). It creates variables that simulate POST variables. This is the code to store or set a variable:
Yii::app()->user->setState('var', 'value');
And, in order to trace the value you just code as follows:
Yii::app()->user->getState('param1');
It would equally work with forward, but I'm not sure why you want to use it instead of redirect().
I am new to the extJS framework and after looking at these two classes I am curious when it is better to use one or the other. Is one better for submitting and one for getting? In my current situation I am using a grid and the api says to use the proxy.Ajax which I trust. But lets say I want to send the JSON back to a database, would I be better off using Ext.Ajax?
Also I am rather new to JSON I understand that its just a string with regular expressions essentially. What is the best way to send the json straight to a database if I don’t want to store the json locally?
Ext.Ajax is used to make one-off requests to a server. You can use this for GET and POST requests.
Ext.data.proxy.Ajax is used by the data package, in particular, Ext.data.Store's. You cannot use this 'manually'. You must use it via the data package.
