没有在PHP中获取json数组

Question

I am passing a json in my ajax request but it is just returning 10 every time, why??

whay my array in not getting passed??

Here is my code:

jQuery(document).ready(function($){
    $('#list-3 .ajaxcall').click(function(){
        $.ajax({
            type : "GET",
            url : ajaxurl,
            dataType: 'json',
            contentType: "application/json; charset=utf-8",
            data : { 
                    gpl_args : JSON.stringify({"cat":"26","posts_per_page":"4","paged":1}),
                    gpl_layout : {"show_thumb":"1","columns":"4","thumb_height":"85","thumb_width":"85","title_link":"1","content_excerpt":"50","posts_per_page":"4"}
            },
            success : function(response) {
                // The server has finished executing PHP and has returned something,
                // so display it!
                $("#list-3").append(response);
            }
        });
    });
}); 

and:

$args       = isset($_REQUEST['gpl_args']);
//$args         = json_encode(isset($_REQUEST['gpl_args']));
print_r($args)

Update:

my data inside ajax:
   data    : { gpl_args : JSON.stringify(<?php echo json_encode($args); ?>),
              JSON.stringify(gpl_layout   : <?php echo json_encode($layout); ?>)},

Simple fix. You have to DE-code the json, not EN-code it.

$args = isset($_REQUEST['gpl_args']) ? $_REQUEST['gpl_args'] : null;
$args = json_decode(stripslashes($args));
print_r($args)
