Question

I try to post an JS object to PHP, but the PHP says nothing.. It looks like it don’t recognize the POST…

Here is the JS :

$('.send').click(function() {
    var Scommand = JSON.stringify(command);// Command is my JS obj

    if (commande.type) {
        $.ajax({
            url:'test.php',
            context:$(this),
            type:'POST',
            data:Scommande,
            success : function(data){
                commande = {};
                window.location='test.php';
            }
        });//End Ajax
    }
    else {'PLz specify a type');}
});

And my PHP :

<?php
echo $_POST['type'];
?>

It returns : Notice: Undefined index: type in /Applications/MAMP/htdocs/BackOfficeDavid/test.php on line 2

Like nothing go throw the POST … Any clue ?

The problem is that you’re converting the command to a string. The data on the ajax call has to be a JSON object, not a string. What you can do is pass the command variable directly:

var command = { type: "whatever" };

$.ajax({
    url:'test.php',
    context:$(this),
    type:'POST',
    data: command,
    success: function(data){
       command = {};
       window.location='test.php';
    }
});
