Send a post request to a php page using ajax - php

Question

I'm trying to send a text that is typed via ajax to a php page that will make a query using that text that is received. I want to know how to send the value of variable nmClient to the php page. I tried the following code and the return was 500 (Internal Server Error). I'm using the framework Symfony
Jquery
var name = $("#name").val();
$.ajax({
url: "../search",
type: "POST",
data: {'name':name},
dataType: "json"
}).done(function(response) {
console.log(response);
}).fail(function(jqXHR, textStatus ) {
console.log("Request failed: " + textStatus);
}).always(function() {
console.log("done");
});
PHP
public function searchAction(Request $resquest)
{
if ($request->isXMLHttpRequest()) {
$name = $request->get('name');
return new JsonResponse(array('name' => $name));
}
return new Response('This is not ajax!', 400);
}

I believe you're trying to access the parameter name in the incorrect place. The get() method is available on the ParameterBag instance, not the Request instance. Try the following:
$name = $request->request->get('name');
Per the docs here:
Each property is a ParameterBag instance (or a sub-class of), which is a data holder class:
request: ParameterBag;
query: ParameterBag;
cookies: ParameterBag;
attributes: ParameterBag;
files: FileBag;
server: ServerBag;
headers: HeaderBag.
All ParameterBag instances have methods to retrieve and update their data:
get() Returns a parameter by name.
Here is the example from that same page:
// the query string is '?foo[bar]=baz'
$request->query->get('foo');
In the docs example case, the parameters are passed via the GET method as a query string but they access them via the query ParameterBag instance. You'll want to use the request Parameter Bag instance since your parameters are passed via the POST method.
