How to use user's input to run another function in Flask - Python?

Question

Hi The idea of my code is to allow the user to submit an ID through using this form

@app.route('/')
def home():
   return '''
   <form method="get">
    <textarea name="textbox"></textarea>
     <button type="submit" name="submit">Submit</button>
      </form> '''

Then the user ID is read by this route and other calculations are done

@app.route('/')
def api_id():
   text = request.form.get('textbox')
    ## Do other calculations

My issue is that when the user inputs the ID nothing happens, only the URL changes but the calculations are not reflected.. Can you please help?

You need to specify the route that will receive the POST request from the form:

@app.route('/')
def home():
  return '''
   <form method="POST" action="/get_id">
    <textarea name="textbox"></textarea>
    <button type="submit" name="submit">Submit</button>
  </form> 
   '''
@app.route('/get_id', methods=['POST'])
def get_id():
  id = flask.request.form['textbox']
  #do something
