image/file upload does not work

Images/files not uploading,
in addition, I get following warning after submiting new flexinode content

* warning: Attempt to assign property of non-object in H:\Web\workspace\rr\modules\flexinode\field_image.inc on line 47.
* warning: Attempt to assign property of non-object in H:\Web\workspace\rr\modules\flexinode\field_image.inc on line 48.

in this function

function flexinode_field_image_insert($field, $node) {
  $fieldname = 'flexinode_'. $field->field_id;
  $node->$fieldname = file_save_upload($node->$fieldname, $node->$fieldname->filename);
  $node->$fieldname->smallpath = flexinode_field_image_make_smaller($node->$fieldname->filepath, '_sm', $field->options[2]);
  $node->$fieldname->thumbpath = flexinode_field_image_make_smaller($node->$fieldname->filepath, '_th', $field->options[3]);
  $serialized = is_object($node->$fieldname) ? serialize($node->$fieldname) : '';
  db_query("INSERT INTO {flexinode_data} (nid, field_id, textual_data, serialized_data) VALUES (%d, %d, '%s', '%s')", $node->nid, $field->field_id, $node->$fieldname->filename, $serialized);
  return $node;
}

sorry for changing the title..

This could be connected to this bug http://drupal.org/node/38924

I've already applied field_image.inc patch.. no change..
Neither uploads via upload.module doesnt work.. strange..
tried also with js off - no change..
isnt browser related.. tried in IE6, FF1.5

had the same (didn't tested the image field - i need only files) - the uploaded file was not copied to files directory and the database field was empty.

compared the new field_file.inc with the old one (4.6) and did the following:

field_file.inc on line 34:

function flexinode_field_file_insert($field, $node) {
  $fieldname = 'flexinode_'. $field->field_id;
  $serialized = is_object($node->$fieldname) ? serialize($node->$fieldname) : '';
  db_query("INSERT INTO {flexinode_data} (nid, field_id, textual_data, serialized_data) VALUES (%d, %d, '%s', '%s')", $node->nid, $field->field_id, $node->$fieldname->filename, $serialized);
}

changed to:

function flexinode_field_file_insert($field, $node) {
  $fieldname = 'flexinode_'. $field->field_id;
    //changed code:
  $node->$fieldname = file_save_upload($fieldname, variable_get('file_directory_path', 'files'));
  if (empty($node->$fieldname)) {
    $node->$fieldname = ($node->{$fieldname .'_old'});
  }
    // eof change
  $serialized = is_object($node->$fieldname) ? serialize($node->$fieldname) : '';
  db_query("INSERT INTO {flexinode_data} (nid, field_id, textual_data, serialized_data) VALUES (%d, %d, '%s', '%s')", $node->nid, $field->field_id, $node->$fieldname->filename, $serialized);
}

i suppose its not the right way since there must have been a reason why this was splited into two functions in 4.7, but it works for me.

Does editing entries with files / images work for you? On my installation it wants to upload new files even if I dont choose new files in the file-boxes.

the update didn't work, another fix, works for me:
field_file.inc, after line 33:

function flexinode_field_file_insert($field, $node) {
  $fieldname = 'flexinode_'. $field->field_id;
  $node->$fieldname = file_save_upload($fieldname, variable_get('file_directory_path', 'files'));
  if (empty($node->$fieldname)) {
    $node->$fieldname = ($node->{$fieldname .'_old'});
  }
  $serialized = is_object($node->$fieldname) ? serialize($node->$fieldname) : $node->$fieldname;
  db_query("INSERT INTO {flexinode_data} (nid, field_id, textual_data, serialized_data) VALUES (%d, %d, '%s', '%s')", $node->nid, $field->field_id, $node->$fieldname->filename, $serialized);
}

function flexinode_field_file_delete($field, $node, $unconditional = 0) {
  $fieldname = 'flexinode_'. $field->field_id;
  $result = db_fetch_object(db_query('SELECT serialized_data FROM {flexinode_data} WHERE nid = %d AND field_id = %d', $node->nid, $field->field_id));
  $file = unserialize($result->serialized_data);
  $node->$fieldname = file_check_upload($fieldname);
  if ($unconditional || ($node->$fieldname != $file and !empty($node->$fieldname)) ) {
    file_delete($file->filepath);
  }
}

this is just for file field, the image field should be similar.

It can't be similar, though the validate fonction is used to modify node field value, which is not allowed with 4.7 API.
Hope it helps

please provide a real patch. http://Drupal.org/diffandpatch
