This morning I was trying to upload a file through the media section.
Kept getting an error so I went in to do some testing.
Was echoing out the upload result, tried changing file permissions, undid everything, and am now ending up with random errors.
Here is one (this one just started),
Fatal error: Call to undefined function set_screen_options() in/wp-admin/admin.php on line 74
The first error I started running into is this,
Parse error: syntax error, unexpected $end in /wp-admin/includes/file.php on line 348
Here is the function containing line 348
function wp_handle_upload( &$file, $overrides = false, $time = null ) {
// The default error handler.
if ( ! function_exists( 'wp_handle_upload_error' ) ) {
function wp_handle_upload_error( &$file, $message ) {
return array( 'error'=>$message );
}
}
$file = apply_filters( 'wp_handle_upload_prefilter', $file );
// You may define your own function and pass the name in $overrides['upload_error_handler']
$upload_error_handler = 'wp_handle_upload_error';
// You may have had one or more 'wp_handle_upload_prefilter' functions error out the file. Handle that gracefully.
if ( isset( $file['error'] ) && !is_numeric( $file['error'] ) && $file['error'] )
return $upload_error_handler( $file, $file['error'] );
// You may define your own function and pass the name in $overrides['unique_filename_callback']
$unique_filename_callback = null;
// $_POST['action'] must be set and its value must equal $overrides['action'] or this:
$action = 'wp_handle_upload';
// Courtesy of php.net, the strings that describe the error indicated in $_FILES[{form field}]['error'].
$upload_error_strings = array( false,
__( "The uploaded file exceeds the <code>upload_max_filesize</code> directive in <code>php.ini</code>." ),

return call_user_func($upload_error_handler, $file, __( 'Invalid form submission.' ));
// A successful upload will pass this test. It makes no sense to override this one.
if ( $file['error'] > 0 )

if ( is_multisite() )
$error_msg = __( 'File is empty. Please upload something more substantial.' );
else
$error_msg = __( 'File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini or by post_max_size being defined as smaller than upload_max_filesize in php.ini.' );
return call_user_func($upload_error_handler, $file, $error_msg);
}
// A properly uploaded file will pass this test. There should be no reason to override this one.
if ( $test_upload && ! @ is_uploaded_file( $file['tmp_name'] ) )
return call_user_func($upload_error_handler, $file, __( 'Specified file failed upload test.' ));
// A correct MIME type will pass this test. Override $mimes or use the upload_mimes filter.
if ( $test_type ) {
$wp_filetype = wp_check_filetype_and_ext( $file['tmp_name'], $file['name'], $mimes );
extract( $wp_filetype );
// Check to see if wp_check_filetype_and_ext() determined the filename was incorrect
if ( $proper_filename )
{
$file['name'] = $proper_filename;
}
if (( !$type || !$ext ) && !current_user_can( 'unfiltered_upload' ) )

if ( ! ( ( $uploads = wp_upload_dir($time) ) && false === $uploads['error'] ) )
{
return call_user_func($upload_error_handler, $file, $uploads['error'] );
}

delete_transient( 'dirsize_cache' );
return apply_filters( 'wp_handle_upload', array( 'file' => $new_file, 'url' => $url, 'type' => $type ), 'upload' );
}
Line 348 Is this line:
return call_user_func($upload_error_handler, $file, __( 'Sorry, this file type is not permitted for security reasons.' ));
Any thoughts?
I checked brackets, parenthesis, commas, semi-colons, and am slowly but surely testing cutting each function out.
Removing wp_handle_sideload and wp_handle_upload functions and a few miscellaneous ones will allow the pages to load, but have no functionality
