How to make an array in struct to use it in a loop?-CodePudding

I have 34 products in a CSV file and I want to use each of them in an HTML file. For this purpose, I need an array key so that I can use a value in an HTML file one by one.

Problem

Whenever I execute this code, it prints only the last product name.
I don't know how to make an array in a struct so that I can use it as a key using the for-loop.

Code

type List struct {
    ProductsList string
}

func Home(w http.ResponseWriter, r *http.Request) {
    var user List
    for i := 0; i < 34; i   {
        user = List{
            ProductsList: products.AccessData(i),
        }
    }
    HomeTmpl.Execute(w, user)
}

CodePudding user response：

We can make ProductsList a slice(fancy array) by delaring it like this []string. We can then use the append function to add elements to the end of the slice. This will make a slice where the index of the slice matches i.

type List struct {
    ProductsList []string
}

func Home(w http.ResponseWriter, r *http.Request) {
    var user List
    for i := 0; i < 34; i   {
        user.ProductsList = append(user.ProductsList, products.AccessData(i))
    }
    HomeTmpl.Execute(w, user)
}

Try this bro

I change ProductList properties to slice string

type List struct {
    ProductsList []string
}

func Home(w http.ResponseWriter, r *http.Request) {
    
    AllData := []string{}

    for i := 0; i < 34; i   {
        append(AllData, products.AccessData(i))
    }

    user := List{ ProductsList: AllData }
    // user.ProducList = ["yourdata","hello","example","and more"]

    HomeTmpl.Execute(w, user)
}
