jquery ajax表单已发送，但var_dump（$ _ POST）为空

Question

everyone, i got a very simple problem, but i am really confused... for un hour

in a php page, i have the code:

<script>
$( document ).ready(function() {
  $("#date_avant").click(function(){
    $.post( "_corps_medecin_changedate.php", { name: 'test', id: '1' } );
    $("#consultations_jour").load("_corps_medecin_changedate.php");
  });
});
</script>

And in the page _corps_medecin_changedate.php, just at the beginning, i have the code:

<?php
var_dump($_POST);
$date_debut = $_POST['name'];
?>

And i got msg:

array (size=0)
  empty
Notice: Undefined index: name

I checked the firebug, the parameters are correct in the post list, so i thinked it is sended correctly, but just canot receive in the action page.

Server info :   Apache/2.2.11 (Win32) PHP/5.4.4

And in local envirment.

Can anyone help me?

Your returned data from your $.post call is not automatically made available to your .load() call. They are two separate functions which means your call to load essentially send no POST data to the PHP script.

You can pass the post parameters as part of your call to load

<script>
    $( document ).ready(function() {
        $("#date_avant").click(function(){
            $("#consultations_jour").load("_corps_medecin_changedate.php", { name: 'test', id: '1' });
        });
    });
</script>
