Not getting post value from file_get_contents('php://input')

Question

I am having an issue when I am using a post request on an PHP file and I am passing simple keys and values to post. For example say key = productId and value = 123 .

<?php

$data_back = json_decode(file_get_contents('php://input'));

return $data_back;

I am receiving nothing. Please assist.

Answer 1

1. Check how is your request created. It must be POST and php://input is not available for enctype="multipart/form-data"

2. Problem may be json_encode() receiving invalid JSON. Check for json_decode error and/or check if the output from file_get_contents('php://input') is really empty.

Answer 2

in PHP file you can catch post request variabile just using $_POST array.

<?php

$data_back = $_POST;

return $data_back;

?>
