Method GetPostForm

context.go:624–629

GetPostForm is like PostForm(key). It returns the specified key from a POST urlencoded form or multipart form when it exists `(value, true)` (even when the value is an empty string), otherwise it returns ("", false). For example, during a PATCH request to update the user's email: email=mail@ex

(key string)

//		   email=                  -->  ("", true) := GetPostForm("email") // set email to ""
//	                            -->  ("", false) := GetPostForm("email") // do nothing with email
func (c *Context) GetPostForm(key string) (string, bool) {
	if values, ok := c.GetPostFormArray(key); ok {
		return values[0], ok
	}
	return "", false
}

// PostFormArray returns a slice of strings for a given form key.
// The length of the slice depends on the number of params with the given key.
