Can you post JSON data to the same URL (PHP Program)?

<html>
<head>
<title> </title>

</head>
<body>

<?php

$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);

If (!isset($_POST['submit']))
{
echo ("Submit was not pressed!!!") ;
$jsondata = json_encode($arr);
print_r($jsondata); // used to test data encode

print("<form action=\"http://192.168.1.9:10088/jquery/jsontest.php?data_sent=".$jsondata."\" method=\"POST\">");
?>
<input type="Submit" name="submit" value="submit">
</form>

<?php
}
else
{
echo ("Submit was pressed!!!") ;
$data = json_decode($_POST['jsondata']); //get JSON data and place in array for use
$newarr = json_decode($data) ;
print_r($newarr); // used to test data post and decode
}
?>
</body>
</html>

Yes, but you've done it wrong.

First you made "data_sent" a GET value. You need to move it to a hidden input field so the data ends up in the POST array.

Code: Select all: <input type="hidden" name="data_sent" value="<?php echo $jsondata ?>" />

Second, the decoding is all wrong. You've got this

Code: Select all: $data = json_decode($_POST['jsondata']); //get JSON data and place in array for use $newarr = json_decode($data) ;

Nothing in the form was named 'jsondata', and you're running it through json_decode() twice.
This should work:

Code: Select all: $newarr = json_decode($_POST['data_sent']); //get JSON data and place in array for use
