PHP Warning: property “post_type” on null

Hello

I would like to draw your attention to a PHP warning that occurs in your plugin called Shortcoder. The PHP warning is caused in the file /shortcoder/admin/tools.php, on line 54.

This line of code causes the PHP warning:

return ( $screen->post_type == SC_POST_TYPE && $screen->base == 'post' );

It happens when the variable $screen happens to be null. Then $screen->post_type can not be accessed and therefore the return statement itself fails.

To mitigate the problem I made the following change in your code:

if ( null !== $screen )
  return ( $screen->post_type == SC_POST_TYPE && $screen->base == 'post' );
else
  return null;

You can make whatever adjustment you think is best in this case for your code. I am just trying to direct your attention to this issue.

Sincerely,
Gevorg
