Why am I unable to access the json data POST'd to my codeigniter application?

json codeigniter rest post curl

Your post data is not in query string format so you should skip dealing with $_POST and go straight to the raw post data.

try

var_dump($HTTP_RAW_POST_DATA);

or even better

var_dump(file_get_contents("php://input"));

json codeigniter rest post curl

in codeigniter 2.X, you can override Input class and add necessary functionality.https://ellislab.com/codeigniter/user-guide/general/core_classes.html

add file MY_Input.php to application/core
add code inside this file:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');class MY_Input extends CI_Input {    public function raw_post() {        return file_get_contents('php://input');    }    public function post($index = NULL, $xss_clean = FALSE) {        $content_type = $this->get_request_header('Content-type');        if (stripos($content_type, 'application/json') !== FALSE            && ($postdata = $this->raw_post())            && in_array($postdata[0], array('{', '['))) {            $decoded_postdata = json_decode($postdata, true);            if ((json_last_error() == JSON_ERROR_NONE))                $_POST = $decoded_postdata;        }        return parent::post($index, $xss_clean);    }}
