How do you restrict file extension types when customers create an incident on the Ask a Question page?
Customer Portal, File Attachments
In Customer Portal, there is a 'valid_file_extensions' attribute in the 'FileAttachmentUpload2' widget where you can define a list of accepted file extensions without leading periods and separated by commas. Please note, the 'valid_file_extensions' default for the attribute is defined by all extensions.
You can edit this widget by going to the path below:
Customer Portal v3.x:
<rn:widget path="input/FileAttachmentUpload" valid_file_extensions="gif,pdf,doc"
Customer Portal v2.x:
To edit widgets, you will need to access to Customer Portal first. For more information about Customer Portal, please see Overview of Customer Portal section in documentation.
