Is it possible to send an empty array to PHP from JS using JSON?
<?
if ($_GET['test']) {
$data = $_GET['data'];
print_r($data);
exit;
}
?>
<head>
<script type="text/javascript" src="jquery-1.6.4.min.js"></script>
</head>
<script type="text/javascript">
$.getJSON('temp.php', {
"test": 1,
"data": []
})
</script>
This is a simplified version of what I'm trying to do. Basically, I'm sending data to PHP so it can update the database. If I send an empty array, it should save an empty array. However, in the above example, only "test" gets passed and "data" gets thrown away. The only solution I can think of is to do something sloppy, like this:
if (! isset($data = $_GET['data']))
$data = array();
So, I'm basically just making an empty array after JSON/JS throws it away. Unless there's another way? Thank you!
$.getJSON('temp.php', {
"test": 1,
"data": JSON.stringify([])
})
