this is my php file

$json = json_decode($_POST,true);
echo $json[1]; //this bring me always blank

What i’m doing wrong in my code

Answer 1

echo $json['IdModelo'];

This is how you get it.

Passing the second argument true to json_decode will return an associative array so you should access array values using associative (string) index.
