Title
Body
I've searched over the internet for half an hour but cannot find one. I want to use the managed_file form api in D7 to allow use upload image file; more specifically, I think "#upload_validators" property may do the trick (if possible, to validate file extension before uploading; or at least, validate in the validation phase but not in the submit function). I've checked the image_example and file_example in the example modules, but cannot find a proper usage of it. So I wonder if there's a proper tutorial on managed_file? Thanks a lot. Update: I saw an example after doing a search on drupal directory from file.field.inc, and following the example, wrote code like this: $form['file_upload'] = array( '#type' => "managed_file", '#title' => t("Upload"), '#descripion' => t("Only Image Files are allowed."), '#progress_indicator' => "bar", '#upload_location' => "public://img/dish", "#upload_validators" => array("file_validate_extensions" => "png gif jpg"), ); This solved the problem.
