Unable to pass an Array to the Controller

let formData = new FormData();

payloadData = JSON.stringify(payload.unitDoctors);
for (var prop in payloadData) {
  formData.append(prop, payloadData[prop]);
}
axios({
    method: "put",
    url: apiUrl + payload.id,
    data: formData
  })
    .then(response => {
      commit("updateRecord", response.data);
    })
    .catch(error => {
      commit("setErrors", error.response.data);
    });
}

Why does the api controller always receive null for unitDoctors(array) when FormData is sent? Any solutions?

Answer №1

Consider avoiding the unnecessary stringification of your data when attempting to iterate over a string using JSON.stringify. It might be beneficial to remove that specific call in order to accurately pinpoint the issue at hand. However, without visibility into your dataset and desired outcome, it is challenging to provide a definitive solution.
