Mais l'informaion ne sera pas affiché sur le "agendaWeek".
Quelqu'un peut-il me dire ce que je fais de mal.

Mon "json_events.php" le code est:

<?php

 $year = date('Y');
 $month = date('m');

 echo json_encode(array(

  array(
   'id' => 111,
   'title' => "Event1",
   'start' => "$year-$month-22 8:00",
   'end' => "$year-$month-22 12:00",
   'url' => "http://yahoo.com/"
  ),

  array(
   'id' => 222,
   'title' => "Event2",
   'start' => "$year-$month-22 14:00",
   'end' => "$year-$month-22 16:00",
   'url' => "http://yahoo.com/"
  )

 ));

?>

Et il résu suivantes:

[{"id":111,"title":"Event1","start":"2010-03-22 8:00","end":"2010-03-22 12:00","url":"http:\/\/yahoo.com\/"},{"id":222,"title":"Event2","start":"2010-03-22 14:00","end":"2010-03-22 16:00","url":"http:\/\/yahoo.com\/"}]

S'il vous plaît si quelqu'un peut aider ou vous suggérer quelqu'un pour m'aider.

Grâce,
Dennis
