Hi,
I have the requirement where I need to validate things like image format,
height, width etc for a file upload.
I'd like to do this using validators, which I can do - but im curious if its
the right way.
Here is what I currently have.
form.add(fileUploadField = new FileUploadField("fileInput") {
protected void convertInput() {
setConvertedInput(getFileUpload());
}
});
fileUploadField.add(new AbstractValidator() {
protected void onValidate(IValidatable validatable) {
FileUpload fileUpload = (FileUpload)validatable.getValue();
if (fileUpload.getContentType().equals("text/plain")) {
error(validatable);
}
}
protected String resourceKey() {
return "CustomFileError";
}
});
This works... but is it correct?
I'm not handling it in the onSubmit - and don't believe I should have to -
despite the examples.
I have double submit implemented on my base form in a similar fashion to
what igor recommends here
http://www.nabble.com/double-form-submission-handling---tp13816084p13850262.html
- which means I only execute the "submit" if all the validation passes.
This works SUPER AWESOME thus far :)
