PHP RESTful services; AJAX and DELETE method with username/password credentials -

i asked question related restful services here, , have question involving delete (put):
same kind of situation want send along user credentials (username/password) put. delete service far:

$http_req   = $_server["request_method"]; switch ($http_req) {     case delete:         $user = $acct->read($_request["usernamedel"], $_request["passworddel"]);  // method used read db table 1 record         if (!empty($_request["deltaskid"]) && isset($_request["usernamedel"]) && isset($_request["passworddel"])) {             if ($user == true) {                 $delete     = fopen("php://input", "r");                 $data       = stream_get_contents($deleted);                 $params;                 parse_str($data, $params);                 $dropped = $mgr->delete($params["id"])  // calls method deletes particular row based on id                 echo $dropped;             }         }                 } 

this html page working with. updated in :

<form action="taskservice.php" method="post"> <label for="usernamedel">username</label>     <input type="text" name="usernamedel" id="usernamedel" required/><br /> <label for="passworddel">password</label>     <input type="password" name="passworddel" id="passworddel" required/><br /> <label for="deltaskid">task id</label>     <input type="text" name="deltaskid" id="deltaskid" required/><br /><br /> <button type="button" id="btndelete">delete task</button><br /><br /> </form> 

this ajax code (edit-now using @devs modifications):

$("#btndelete").click(function() {      $.ajax({             method: "delete",               url: "taskservice.php",               data: { 'username':$("#usernamedel").val(), 'password': $("#passworddel").val(), 'id': $("#deltaskid").val()},             success: function(theresponse) {                 alert(theresponse);             }         }); }); 

currently returns 200 response, gives me error messages had put in account class (comes "could not find account".

gut telling me has $_request[] superglobals since it's not doing form action, not familiar passing information via ajax
thoughts?

just arranged ajax format, syntax error in php code.

note: never tested

ajax

$(document).ready(function(){      $("#btndelete").click(function() {          $.ajax({                 method: "delete",                   url: "taskservice.php",                   data: { 'username':$("#usernamedel").val(), 'password': $("#passworddel").val(), 'id': $("#deltaskid").val()},                 success: function(theresponse) {                      // output                      alert(theresponse); // comment                      }               });     }); });                  

taskservice.php

<?php $http_req   = $_server["request_method"];  switch ($http_req) {     case delete:         $user = $acct->read($_request["username"], $_request["password"]);  // method used read db table 1 record         if ($user == true) {             $delete     = fopen("php://input", "r");             $data       = stream_get_contents($deleted);             $params;             parse_str($data, $params);             $dropped = $mgr->delete($params["id"]);  // calls method deletes particular row based on id             echo $dropped;         }     break; } ?>
