There are getVars(), postVars() and requestVars() methods in HTTPRequest.
They returns parameters from GET and POST requests.
But how can I get parameters from PUT and DELETE requests?
I know that there is a 'body' property somewhere in HTTPRequest. It contains PUT params in query string or something similar.
To use this property I need to parse 'body' field.
Is there a way to get these parameters with comfortable way, like for GET and POST?
You need to do it the old school way.
parse_str($request->getBody(), $params);
$foo = $params['Foo'];
Keep in mind the second parameter of parse_str is a reference, so no need to define that variable before invoking the function call.

I use $.getJSON() to retrieve some data for a couple of cascading dropdowns in my form. $.getJSON() automatically appends the parameter at the end of the URL like domain.com/controller/method/?parent=5
So, I've declared my method like public function method($parent) which works file, but the same method will be used from other parts of the website that will call it like domain.com/controller/method/5
I tried to create a route in routes.php like the one below:
$route['business/regions/?parent=(:num)'] = 'business/regions/$1';
but it doesn't seem to work. Am I doing something wrong? Maybe ? is confusing the regex parser of the router? Do I have to escape it somehow to make it a 'literal' ? ?
Or is it that router is not used to 'rewrite' get parameters at all? I'm very confused, as it should work but it doesn't and I'm wondering what's wrong with it...
Codeigniter route parameters are for url parameters. It is particularly useful when trying to create a REST styled url pattern.
What you're trying to do is get url query string from the url which is not supported via the Codeigniter router. For you to get what you want you can do the following:
In your routes.php:
$route['business/regions'] = 'business/regions';
and in your controller Business.php:
public function regions() {
//the numeric id you're looking for
$parent = $this->input->get('parent');
}
When we receive a Request object in Laravel, is there a way to modify or add data to it? For instance, could I rename a parameter (not the value, but the parameter name itself) to something else? For example, the input might be called fname but I want to change it to first_name. Or could I add new inputs and values that weren't in the original request?
The reason I ask is that I have a method that accepts a Request object, and expects certain input names. I'd like to be able to reuse the method, but the request input names will be different.
If you have an Object you can edit and add new items.
$request->url = $new_url;
$request->new_item = 1;
If the object item not exists, then will create automatically, or if it exists, will modify it.
Tested #marc-garcia answer, and that will not persist through your script execution. This will...
// merge defaults into the request.
// this makes it consistent everywhere (blade, controller...)
request()->merge([
// find the request if it exists, second param is the default value
'reservable' =>request( 'reservable', (self::RESERVABLE_BY_DEFAULT?1:0) )
]);
You may also use request()->replace([...]); but that will remove all other parameters from the request and replace it will the array you provide.
I have an url with query args:
var url = 'http://example.com/ajax.php?action=update_count&product=1234'
So, all query args I need to send for ajax request is already in URL, I tried this:
$.post( url, '', callback, 'json');
But, it won't send POST data.
So, I want to ask shall I do ajax/post request without data object/string, as query args are already in url.
Thanks.
If you put a parameter in the URL, it's treated like a GET parameter, not a POST parameter. You need to use whatever server-side mechanism is normally used for getting URL parameters. For instance, in PHP it would be $_GET['action'] and$_GET['product']`.
If you want to be able to send a parameter in either GET or POST, you can use PHP's $_REQUEST variable. It merges both sets of parameters.
I need to pass product Id from cart to custom controller, for example
http://**/catalogsearch/filter/results?product={ID}
I dont have a clue how to pass data like that using magento helpers etc
Thanks
I am assuming from your question that you are redirecting from one controller to another and would like to pass query parameters along?
The syntax would be:
$params = array('key' => 'value');
$this->_redirect('frontname/controlller/action', array('_query' => $params));
EDIT
To answer the question in the comment on how to get these parameters from a template:
First off, I would advise not to do this, you should be recieving parameters in the controller. So, your custom controller should be responsible for receiving any parameters.
Regardless, the code in either situation is the same:
All parameters…
$this->getRequest()->getParams()
Single parameter…
$this->getRequest()->getParam('parameter_name')
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().
