Post JSON to Codeigniter controller

Question

I am trying to receive and parse a JSON object sent in a POST request using Codeigniter but I cannot \"find\" it.

This is my controller code:

public          


        

Answer 1

This is the correct way to do it.

$input_data = json_decode(trim(file_get_contents('php://input')), true);

Answer 2

In order to use the standard CI methods. In index.php, insert a couple of lines:

    $json = json_decode(trim(file_get_contents('php://input')), true);
    if(!empty($json)) {
        $_POST = $json;
    }

Either implement in the bootstrap. RIP Codigniter...(

Answer 3

try

json_decode(array($this->input->post()))

OR

$tmp[] = (array)json_decode($this->input->post());

print_r($tmp);

Answer 4

Firze's answer is correct but here is a more elaborated answer. I am not allowed to comment so I am posting it as an answer.

It has to do with CodeIgniter not being able to fetch JSON. jQuery does some under the hood tricks and transforms your data into form-data-x, that's why it works when you don't specify the content type, don't encode your object, or other situations.

If you want a pure JSON the solution is to use $this->input->raw_input_stream to fetch your JSON and decode it using php's json_decode. Check the full answer and code below:

Answer 5

Just add correct content type to your request header

Content-Type: application/json

Answer 6

puplic function exam(){
$obj = file_get_contents('php://input');
