Status: Needs Review

@xabbuh thanks for your works.

Your commit resolve the duplicated message and so resolve #39107

but if i remove

uploadIniSizeErrorMessage

    /**
     * @var array<UploadedFile>

     * @Assert\NotBlank(message="Veuillez sélectionner un fichier.")
     * @Assert\All({
     *     @Assert\File(
     *         maxSize = "500k",
     *         maxSizeMessage = "Custom message max size.",
     *         uploadFormSizeErrorMessage = "Custom message max size form",
     *     )
     * })
     */
    public $files;

error message is

normally is

Custom message max size.

other issue ? or side effect with the PR ?

If I understand you correctly, that's expected. The file couldn't be uploaded as the maximum file limit configured for PHP is reached and thus the FileValidator will not perform any additional checks.

@xabbuh i say just i don't understand the behaviour

for me this PR resolve duplicated error Message.

but if i remove Assert uploadIniSizeErrorMessage

default message maxSize is applied instead MaxSizeMessage

For me, the expected behaviour is

I'm not sure is a side effect with this PR

Well, if the file exceeds the limit configured with upload_max_filesize the uploadIniSizeErrorMessage is used. If you do not configure it explicitly, its default value The file is too large. Allowed maximum size is {{ limit }} {{ suffix }}. will be used. The message configured with maxSizeMessage is only taken into account if the file size is below the limit configured with upload_max_filesize, but exceeds the maxSize value of the File constraint. So the results that you observe look expected to me.

Thank you @xabbuh.

Hi, I can confirm it is fixed in 5.1.9. Thank you.
