I have this code
files, _ := ioutil.ReadDir("public/my-template/imagesT/gallery/")
for _, f:=range files {
fmt.Println(f.Name())
}
How can return an array contain all f.Name to use them in index.html ?

Create a slice and use append to add the file names in your loop.
var fileNames []string
files, _ := ioutil.ReadDir("public/my-template/imagesT/gallery/")
for _, f := range files {
fileNames = append(fileNames, f.Name())
}
// Now fileNames contains all of the file names for you to pass to your template.
Also note that you should not ignore the possible error returned on the line
files, _ := ioutil.ReadDir("public/my-template/imagesT/gallery/")

i want to say that when i passed files in this code controller.carService.InsertImages(&fileNames) and the InsertImages function func (r CarService) InsertImages(images *[]string) { session, _ := mgo.Dial(r.uri) defer session.Close() session.SetSafe(&mgo.Safe{}) collection := session.DB(r.dbName).C(r.collectionName) for _, image := range images { error := collection.Insert( models.Car{ImagePath:image}) if error != nil { } } } i have error say : cannot range over images (type *[]string)
