If i copy and paste some part of the URL (maybe 50%) it’s work.

I don’t see where you are requesting a file in your code, the error is apparently coming from somewhere else. I think it is likely that URL is overflowing the allowed length for URLs. When that much data needs to be transmitted, the form should be using POST method, not GET. The form values are then available from $_POST or $_REQUEST in the code within the form’s action destination.

it’s an “add-code” for add some filters into media library.

The form it’s on the upload.php page

I don’t understand…
Same code.. different computer.. (but same OS and Browser) and now it’s working.

Different browser versions maybe? Newer versions may be more tolerant of long URLs, IDK. Regardless, passing large amounts of data as URL parameters strikes me as a poor strategy. WP normally uploads via async POST, so it’s unclear to me why so much data is in an URL. This is all probably unrelated to your code, rather it’s a problem of whatever filter plugin you are modifying. I suggest you contact the filter plugin author and inquire about problems with long URLs.
