Why does converting FormData to an object lose multiple selected values?
KitForma editorial guide. A multi-select can submit several entries with the same name.
Step-by-step guidance
A multi-select can submit several entries with the same name. Object.fromEntries keeps only one value per key, so read
formData.getAll("category") for that field and validate every entry. Use an explicit schema to distinguish single-value and multi-value fields. Verify zero, one and several selections; changing the HTML name to look like an array does not automatically change JavaScript FormData semantics.Sources and verification
