Topic: is possible validate a mdb-file-upload ?

DEVGASA priority asked 2 months ago

Expected behavior validate a mdb-file-upload with a reactive form

Actual behavior the mdb-file-upload don't have validation

Resources (screenshots, code snippets etc.) How can we validate the mdb-file-upload using a reactive form?

example using:

<mdb-file-upload #fileUpload
          [removeBtn]="'Delete'" [defaultMsg]="'Select a image'"

is it possible to include it in a formControlName? How can we validate that it has a selected file?

This plugin has built-in validation for things like file size, type or quantity but it is not possible to add required validation using formControlName.

To check if a file is added you could create a new local variable and update it accordingly when (fileAdded) or (fileRemoved) events are fired.
