Extending File Name Validation in AEM Assets

AEM 6.3 by default restricts some characters in file name.

How can I extend the restriction for a few more characters?

    Hi,

    We were able to extend the filename name validation functionality to few more characters (say '-' here) in AEM 6.3 assets successfully. The following js file is responsible for filename validation:

    /libs/dam/gui/coral/components/commons/fileupload/clientlibs/fileupload/js/fileupload.js

    For extending the restriction functionality to few more characters, we need to overlay the above node (fileupload.js) and make the required changes in it.

    Changes to be made in overlay location (/apps/dam/gui/coral/components/commons/fileupload/clientlibs/fileupload/js/fileupload.js):

    Sample output:

    We hope this helps!

    We asked Eng to look at this question. This logic is somewhere - i am not sure where as i have never read this use case before.

    We need a jcr event listener on new node created in dam. and then add your custom logic to rename the node. use node move logic and save the asset.

    we did this custom logic implementation on page creation. its same for asset upload too.

        Hi Team, 

         

        I am trying to extend the same functionality. There are few more special characters like 'à','ç' (continuous pressing of 'A' in the keyboard will popup these values). So how can I restrict those values ?

         

        Can I change the '_IILEGAL_FILENAME_CHARS' to 'Legal_FileName_Chars' and check the same functionality.

         

        Thanks,

        If you are planning to use custom logic to aem asset com.day.cq.commons.jcr.JcrUtil

        API is usefull.

        <!-- https://mvnrepository.com/artifact/com.day.cq/cq-commons -->

        <dependency>

            <groupId>com.day.cq</groupId>

            <artifactId>cq-commons</artifactId>

            <version>5.8.2</version>

            <scope>provided</scope>

        </dependency>

        This character list is now moved to /libs/dam/gui/coral/components/admin/clientlibs/damutil/js/util.js file which provides a helper function getInvalidFileChars  where any additional characters could potentially be added to the list.
