Ajax post to a php file in a directory not working

问题

I'm using Ajax request for a project and i has lot of problem to make it working I sommetime receive some error 500 (Internal Server Error), but finally everything works until I wanted to move my scripts into a directory.

Here is my Ajax works :

    var xhr = getXMLHttpRequest();
    xhr.onreadystatechange = function() {
    if (xhr.readyState == 4 && (xhr.status == 200 || xhr.status == 0)) {
        callback_like(xhr.responseText, receive);
         location.reload();
      }
    };
    xhr.open("POST", "like.php", true);
    xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    var data = "like=" + receive;
    xhr.send(data);

And this one doesn't work :

    var xhr = getXMLHttpRequest();
    xhr.onreadystatechange = function() {
    if (xhr.readyState == 4 && (xhr.status == 200 || xhr.status == 0)) {
        callback_like(xhr.responseText, receive);
         location.reload();
      }
    };
    xhr.open("POST", "script/like.php", true);
    xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    var data = "like=" + receive;
    xhr.send(data);

Error message in the console : POST: 'url' 500 (Internal Server Error)

I already tried to set all the right to the directory but nothing change..

Thanks

回答1:

An internal server error means that there is probably an error in your code. Any references or includes of other files that need to be adjusted? If the file wouldn´t be found you´d get a 404 Not Found in your response.

Enable error output in php to get a more detailed error message from php.
