[SalesForce] Examples of lightning-file-upload for Community Guest Users

I have a public community that allows a guest user to submit a form (LWC) and create a case record. I now want to embed the lightning:fileUpload component inside the form to allow them to attach a file to the case record. After testing, the case record is created, the ContentVersion record is also created, but is not linked to the case record.

Salesforce documentation does not elaborate on how to handle the logic to do that.

To associate a file (ContentVersion) to the Case record, I wrote an after insert trigger on the ContentVersion object to create a ContentDocumentLink record, associating the ContentVersion to the Case record. A custom field was created on ContentVersion object and on the HTML markup, the CaseId is passed to the attributes: file-field-name and file-field-value. So that when a ContentVersion record is created, the new custom field is populated, and is read by the trigger to pass to the ContentDocumentLink creation. On the front end side, the Case record would have to be created first in order to fetch the CaseId.

[SalesForce] File is uploaded in the private library or public library

You have to populate FirstPublishLocationId, according to ContentVersion documentation:

ID of the location where the version was first published. If the version is first published into a user's personal library or My Files, the field will contain the ID of the user who owns the personal library or My Files. If the first version is published into a public library, the field will contain the ID of that library.

This field is only set the first time a version is published via the API. It isn't set when a version is published in Salesforce CRM Content or uploaded in Salesforce Files or. After the version is published, it is a read-only field.

If you don't set a FirstPublishLocationId via the API, this field defaults to the user's personal library, unless Origin is set to H, then this field defaults to My Files.

You can also reference Special Access Rules section from the link above where they have listed all requirements for the users trying to publish to public library.

event.detail.files returns a list of uploaded files with the attributes name and documentId.

If you pay attention to Your code, you have used Capital N in name attribute whereas expected is small as JavaScript is case sensitive.

alert(uploadedFiles[0].name); // it will work fine
