HTML表单提交不发送任何数据

Question

I have this form:

<form action="" method="post" id="login_form">
  <input type="text" name="log_login_form"/>
  <br/>
  <input type="password" name="log_password_form"/>
  <br/>
  <button type="submit" value="Login" id="log_submit" disabled="disabled" name="action" data-toggle="tooltip" data-placement="bottom">Login</button>
</form>

After a submit the page refreshes, but with php server not getting any data. var_dump($_POST); returns array(0) {} .

In the form action="" refers to index.php that handles form submits. (Changing to action="index.php" didn't help)

The button has some extra attributes for a script disabling it until all inputs are filled:

login_form.find('input').on('keyup blur', function () {
  if (login_form.valid()) {
    $('#log_submit').prop('disabled', false);
  } else {
    $('#log_submit').prop('disabled', 'disabled');
  }
});

Removing the script and changing the button to a regular one didn't help either so I guess the problem doesn't lie there.

I've also tried submitting from external button using javascript: <button onclick="document.getElementById('login_form').submit();"></button> (Ended up with the same behaviour.)

And a throwaway try (that I've read, might work) was adding/ removing the / slashes before closing tags.

Could it be a problem with my php configuration?

Thanks for any help.

Thanks to Craig 's answer I was able to track down the issue. As the form data was there and GET method was working as intended.

Turns out it's caused by a bug in an IDE I was using. This bit of code fixed the problem:

$_POST = array(); //workaround for broken PHPstorm
parse_str(file_get_contents('php://input'), $_POST);
