I am new to wordpress coding.
I've problem to get post_data in wordpress , because I can't var_dump (using ajax process) so I can not see full data, but in inspect in Chrome got parameter with this value
post_data: billing_first_name=&billing_last_name=&billing_country=ID&billing_address_1=&billing_address_2=&billing_city=&billing_state=&billing_city_ongkir=&billing_subdistrict_ongkir=
How can I get this data per field for example I want to get billing_first_name
Use the wordpress codex for help with wordpress coding issues. Wordpress encodes the POST data so you should use the stripslashes_deep function to access post data if the data is encoded using application/x-www-form-urlencoded or multipart/form-data .
$my_post = stripslashes_deep($_POST);
$my_value = $my_post['billing_first_name'];
See https://codex.wordpress.org/Function_Reference/stripslashes_deep
If you are posting the data using JSON you will need to use something more like this.
$json = file_get_contents('php://input');
$my_post = json_decode($json);
$my_value = $my_post['billing_first_name'];
