File validation

We can test the validity of the files and the entry list itself using the available validation extensions. We can also create a custom validator extension if what we want to validate isn’t available as a default extension.

File Validation

File Extension

Validate files based on their extension.

File Type

Validate files based on their mime type.

File Size

Validate files based on their min and/or max size.

File Name

Validate files based on their name.

Image and Video resolution

Validate images and videos based on their width and height values.

List Validation

List Count

Validate the file list based on the amount of files in the list.

List Size

Validate the file listsize based on the total size of the files in the list.

Custom validation

We use the createValidatorExtension function to create a custom file validator extension
