Kendo ui grid - get data send on READ on my php -

i have seen this answer reagarding sending params on performing read operation, how access var on on php?

this code on client-side:

          datasource = new kendo.data.datasource({           transport: {               read:                {                 url:"basedados.php",                 type: "post",                 datatype: "json",                 data: { "my_param": 1, access_token : "my_token" },  // send parameter "access_token" value "my_token" `read` request               },  

but on .php file, how access it?:

  else   {     $verb = $_server["request_method"];      if ($verb == "post")      {         header("content-type: application/json");          if($_post['access_token']) // this?         {              $formdata = $_post["access_token"];             echo $formdata;          } 

edit: answering rick s, let show more of code:

parametermap: function(options, operation)                {                 if (operation == "read" && options.models)                  {                         return {models: kendo.stringify(options.models)};                  };                 if (operation == "create" && options.models)                  {                    options.models[0].idpai = currentid;                   $('#gridbasedados').data('kendogrid').datasource.read();                    return {models: kendo.stringify(options.models)};                 };                    if (operation !== "read" && options.models)                    {                       return {models: kendo.stringify(options.models)};                   }               } 

and on server side, i(usually) had this:

else {     $verb = $_server["request_method"];       if ($verb == "get")      {         header("content-type: application/json");          $arr = array();         $statement = $pdo->query("select a.iddocumento, a.idpai, a.tipo,a.nome,a.datacriacao,                 a.datamodificacao,b.nome nomeutilizadorcriador,                 c.nome nomeutilizadorupdate                 documento left outer join utilizador b on a.idutilizadorcriador=b.idutilizadores                                     left outer join utilizador c on a.idutilizadorupdate=c.idutilizadores");          $statement->execute();         $result = $statement->fetchall(pdo::fetch_assoc);          echo json_encode(array("data" => $result, "user" => $_session["user"]));     }  

and works, need param, because need compare "idpai".

thanks again.

you don't need post here. use parametermap option send in data.

datasource = new kendo.data.datasource({       transport: {           read:            {             url:"basedados.php",             datatype: "json",           },            parametermap: function(options, operation) {              return {                 access_token : "my_token"              }           }       },       schema: {         data: "data"       } 

php

$formdata = $_get["access_token"]; echo $formdata;
