How to get html from input and save as variable in Python Django

Question

I'm trying to get a simple input (which would be an integer) from the user, and use it as a variable in the next python function. But whenever I try to print the input it returns None. Here's my code:

HTML

  <form action="/./" method="POST">{% csrf_token %}
        <input type="text" name="quantity" placeholder="Repeat" size=2>
        <input type="submit" value="Save!">
      </form>

Python Django (This is just part of the function.)

def saveCriteria(request):
    title = request.POST.get('quantity')
    context = {}
    print(title)
    return render(request, "home.html", context)

Any help or advice would be greatly appreciated!

It prints an empty list "[]"

No JS involved. Pure html

You should add if statement before that:

def saveCriteria(request):
    context = {}
    if request.method == "POST":
        title = request.POST.get('quantity')
        print(title)
    return render(request, "home.html", context)

You should refer to the view function in the html template:

 <form action="url of saveCriteria" method="POST"> 
        {% csrf_token %}
        <input type="text" name="quantity" placeholder="Repeat" size=2>
        <input type="submit" value="Save!">
 </form>
