🎂 How BuddyPress Saves “Age Between”

BuddyPress does NOT support "from/to" fields automatically. It saves whatever text xprofile_set_field_data() receives.

// Save Age Between correctly
$from = (int) $_POST["age_between_from"];
$to   = (int) $_POST["age_between_to"];

$value = "{$from}-{$to}";
xprofile_set_field_data( FIELD_ID, $user_id, $value );

✔ Your plugin already uses this format.

✔ This debug tool shows if BuddyPress actually stored it correctly.

📸 How BuddyPress Saves Profile Photos

BuddyPress does NOT save avatars in database. It saves files in:

The core functions:

• bp_core_avatar_handle_upload() — validates upload
• bp_core_delete_existing_avatar() — deletes old avatar files
• BP_Attachment_Avatar::generate_avatar() — creates thumb
• bp_core_fetch_avatar() — prints the avatar

// How to save avatar programmatically
bp_core_delete_existing_avatar([
   "item_id" => $user_id,
   "object"  => "user"
]);

$bp_avatar = new BP_Attachment_Avatar();

// Pass $_FILES array and input name "avatar"
$file = $bp_avatar->upload( $_FILES, "avatar", $user_id );

$bp_avatar->generate_avatar([
   "item_id" => $user_id,
   "object"  => "user",
]);

bp_core_delete_avatar_cache( $user_id );

This matches exactly what your SFF Avatar Fly-In does.
