根据运输类型 woocommerce 更改付款类型

Question

我在选择交付类型时想要更改付款类型时遇到代码问题。

我有我的代码：

@login_required(login_url="/login/")
def books_issue(request):
    msg = None
    success = False
    if request.method == "POST":
        form = IssueForm(request.POST or None)
        isbn = request.POST.get("isbn")
        student = request.POST.get("student")
        print(isbn, student)
        if form.is_valid():
            print("Form is valid")
            form.save()
            messages.success(request, 'Book Issued Successfully!')
            success = True
            return redirect("books_issue_list")
        else:
            msg = 'Form is not valid'
    else:
        form = IssueForm()
    context = {"form": form, "msg": msg, "success": success}
    return render(request, 'books/books-issue.html', context)

如何确保在选择 99 分钟交货类型时自动更改付款类型？
