I have a backend service, it needs an array of strings (multi select input) and an image, for this reason, I sent request using FormData. But when I pushed only one string to the array field, naturally it's sending it as string instead of array of strings. How can I send it as array even it has a only one element? |

To send an array within
const formData = new FormData();
const array = ['value1', 'value2', 'value3'];
// Append each item in the array with the same key
array.forEach((item) => {
formData.append('key[]', item);
});
const formData = new FormData();
const array = ['value1', 'value2', 'value3'];
// Append the JSON stringified array to the FormData
formData.append('key', JSON.stringify(array));These methods provide flexibility depending on your server-side processing needs. |

To send an array within
FormDatausing Axios, you have two primary options depending on how you want to handle the data on the server side:This method is useful when you want the server to interpret the array as individual key-value pairs.
JSON.stringify:This method is useful when you want to send the entire array as a single entity.
