Hi ! First; WHY can’t I reply to my own post ???

Well, this is what I came to related to this subject. The ajax process succeed (don’t know if its good but it works); but now I can’t decode de JSON object sent… :

in the PHP admin page :

<script type="text/javascript">

//<![CDATA[

var blog_url='<?php echo site_url();?>';

//]]>

</script>

in the JS :

jQuery(submit_button).click(function(){ //CLICK SUBMIT

var dataString = jQuery.toJSON(mainlist.get_tree_array());



jQuery.post(blog_url+'/wp-content/plugins/bp-classifieds/admin/bp-classifieds-ajax.php', {

action: 'bp_classifieds_update_tree',

'blog_url':blog_url,

'cookie': encodeURIComponent(document.cookie),

'_wpnonce': nonce,

'datas':dataString

},

function(response) {

console.log(response);

}, "json");

return false;

});

the ajax file :

<?php

$page_path = getcwd();

$page_path_split = split('wp-content',$page_path);

$wp_path = $page_path_split[0];



include_once($wp_path.'/wp-load.php' );



$function = $_POST['action'];

$function();



function bp_classifieds_update_tree() {

global $bp,$wpdb;

if (!check_admin_referer('classifieds-settings') ) {

echo "NONCE error";

return;

}

$res = json_decode($json, true);

print_r($res);



}

add_action( 'wp_ajax_bp_classifieds_update_tree', 'bp_classifieds_update_tree' );



?>

It works, I can use wpdb functions; the nonce is checked and is OK; but now I have problems with JSON :

If I “console.log” it in my JS, I got

{"0": {"id": "3", "order": 1}, "1": {"id": "4", "order": 2}, "2": {"id": "5", "order": 3}, "3": {"id": "6", "order": 4}, "4": {"id": "7", "order": 5}, "5": {"id": "8", "order": 6}, "6": {"id": "new", "order": 7, "deleted": true}}

Once sent by POST in bp-classifieds-ajax.php;

$json = $_POST['datas'];

$res = json_decode($json, true);

print_r($json);

gives

{"0": {"id": "3", "order": 1}, "1": {"id": "4", "order": 2}, "2": {"id": "5",

"order": 3}, "3": {"id": "6", "order": 4}, "4": {"id": "7", "order": 5}, "5": {"id

": "8", "order": 6}, "6": {"id": "new", "order": 7, "deleted": true}}

but

$json = $_POST['datas'];

$res = json_decode($json, true);

print_r($res);

outputs nothing. What is wrong here ?

Thanks !
