Get data from ajax with symfony

Question

Here my javascript function:

var lastid = 0;
function charger() {
 setTimeout( function(){
 $.post(
 'http://localhost:8000/chat',
 {id: lastid},
 function(data) {
 $('#chat').prepend(data);
 }
 );
 charger();
 },5000);
}

Here my .php controller:

public function addMessagesAction(Request $request){
 $id = $request->request->get('lastid');
 $idall = $request->request->all();
 var_dump($id);
 var_dump($idall);
}

and my result from var_dump:

NULL array(0) { }

my question is:

How to get my "lastid" in my controller ?

• dlopez: You send the lastid variable from your javascript called as id, so you won't get never lastid in you php code. If you want to get lastid you have to send it as {lastid: lastid} in your javascript code.
• 0x4d: i have change id by lastid in my javascript file but the result is same...
• dlopez: Can you show us all the relevant code for the question? For instance, the routing configuratoin whill be very intersting.
• dlopez: Then marks @dragoste answer as the valid one in order to close the question.

Answer 1

That's probably because yo've set in JS id param, not lastid. lastid is JS variable which is assigned to id param

{id: lastid}, //{name: value}

Therefore you should change it to:

{lastid: lastid},
