To validate file type fields before saving to the database, ensure you are using the correct hook and validation logic. The xprofile_data_before_save hook is intended for profile data in BuddyPress, but your issue might be with the validation function itself. Verify that your validate_required_unshared_fields function is properly defined and hooked. Additionally, check that you are correctly accessing and validating the file type fields within this function. Ensure your function looks something like this:
php
Copy code
function validate_required_unshared_fields($field) {
// Add your validation logic here
if (/* validation fails */) {
// Handle validation failure
}
}
add_action(‘xprofile_data_before_save’, ‘validate_required_unshared_fields’);
Make sure to replace the placeholder comments with your actual validation logic.
