i tried example on web server... works expected... , correctly... thing removed beforesend , success javascript functions implementations
i tested , works correctly
html: test.html
<html> <head> <script type="text/javascript" src="//code.jquery.com/jquery-2.1.3.min.js"> </script> </head> <body> <button id="btn">btn</button> <script type="text/javascript"> $(function() { $('#btn').on('click', function(evt) { var photoid = 1; var imgarr = [{ "name": "photo.jpg", "id": 1 }]; $.ajax({ type: 'post', url: 'test.php', data: {'photoid': photoid, 'imgarr' : json.stringify(imgarr)}, beforesend: function(){ }, success: function(response){ alert(imgarr); } }); }); }); </script> </body> </html> php: test.php
<?php //print_r($_post); $photoid = $_post['photoid']; $imagearray = array(); $imagearray = json_decode($_post['imgarr'], true); print_r($imagearray); foreach($imagearray $key=>$value){ } ?> the $imagearray variable array of arrays shown print_r($imagearray) output:
array ( [0] => array ( [name] => photo.jpg [id] => 1 ) ) thus have walk this:
foreach($imagearray $key=>$value){ echo $value["name"]; } or might try function, handles slashes problem in json according magic quotes setting in php:
function _json_decode($string) { if (get_magic_quotes_gpc()) { $string = stripslashes($string); } return json_decode($string); }
