🤗 [Question]: How do we get multiple values for a key in form submission?

[ngocchien]

Question Description

I have a field in my form, its name is the description

Example:

<input name="item" value="item1">
<input name="description" value="description1, this is a description for item one, the first item is very nice, bla bla bla">
<input name="item" value="item2">
<input name="description" value="description2">
<input name="item" value="item3">
<input name="description" value="description3">

On my server side, I define a struct with the information:

FormCreate struct {
		Item    []string                   `json:"item" form:"item"`
		Description  []string         `json:"description" form:"description"`
	}
formData = new(FormCreate)
c.Bind().Body(formData)

I have a problem with binding data from the form to my formData.
My expectation data for formData.Description is []string{"description, this is a description for item one, the first item is very nice, bla bla bla", "description2", "description3"} (This has 3 values for the slice).
But currently, I received for formData.Description after binding data is []string{"description1", "this is a description for item one", "the first item is very nice", "bla bla bla", "description2", "description3"} (This has 6 values for the slice).

It seems that the Bind() function has split the value of the description field of the first item into a slice by the "," , so I received the data for formData.Description is []string{"description1", "this is a description for item one", "the first item is very nice", "bla bla bla", "description2", "description3"}.

Who can resolve my problem?
Thank you so much!

Code Snippet (optional)

package main

import "github.com/gofiber/fiber/v3"
import "log"

func main() {
  app := fiber.New()

  // An example to describe the question
  app.Post("/create-post", handleCreate) 
  log.Fatal(app.Listen(":3000"))
}

function handleCreate(c fiber.Ctx) error{
   FormCreate struct {
		Item    []string                   `json:"item" form:"item"`
		Description  []string         `json:"description" form:"description"`
	}
  var (
    formData = new(FormCreate)
  )
   if c.Method() == http.MethodPost {
	err = c.Bind().Body(formData)
   }
   
   return c.Render("index", fiber.Map{
        "formData": formData,
    })
}
