Question

I would like to send an array I created in my Jquery script to a php file. I know that question has been treated a lot. Unfortunately when applying what seems to be a best practice I do not manage to get it working. Hope someone can help me undertand. Thank you in advance. Cheers. Marc. Here below my code:

my js:

// I build myArray
var myArray = new Array();
$('.someClass').each(function() {
    $this = $(this);
    myArray.push({
        'id': $this.attr('attrId')
    });
});

//...and then send it to myFile.php
var ajaxData = { myArray: JSON.stringify(myArray) };
$.ajax({
    type: "POST",
    url: "myFile.php",
    data: ajaxData,
    success: function(data) {
        $('body').append(data);
    }
});​

my php:

$myArray = json_decode(stripslashes($_POST['myArray']));

foreach($myArray as $value){
    echo $value.'</br>';
}

the error I get:

Catchable fatal error:  Object of class stdClass could not be converted to string

Try replacing this line:

$myArray = json_decode(stripslashes($_POST['myArray']));

With this:

$myArray = json_decode(stripslashes($_POST['myArray']), true);

If the second parameter of json_decode() is set to true, all objects will be converted to associative arrays: http://php.net/manual/en/function.json-decode.php
