How to collect the age of a subject as a variable

  Hi,

  I recommend to use text_input_forms. You can collect all kinds of information like that.

  The error message seems to be quite straightforward, it

  Good luck,

  Eduard

  Hi there, i was looking for the same thing.
  And probably it would help everyone if there was a python code (based on text_input_form) which is accessible to everyone. So everybody could just paste it into an inline_script and that's it.

  It should do the following:
  #1 ask for Birthdate in the format DD.MM.JJJJ
  #2 calculate diff between experiment_date and Birthday
  #3 log the exact age in years (with commas)

  Up to now i was not able to manage that.
  But maybe @eduard this is an easy thing to do?

  Cheers,
  Stephan

  Thanks for this masterpiece http://osdoc.cogsci.nl/3.2/manual/forms/validation/

  I changed the code a little to get the exact age with Birthday.
  Here is the code for anyone who is interested

  def my_form_validator():
  
      """Checks whether both the gender and age fields have been filled out"""
      #also checks for the number of characters
      return var.sex != u'no' and var.byear != u'' and var.bmonth != u'' and var.bday != u'' and len(str(var.byear))==4 and len(str(var.bmonth))==(1 or 2) and len(str(var.bday))==(1 or 2)
  
  def filter_digits(ch):
  
      """Allows only digit characters as input"""
  
      return ch in ['0','1','2','3','4','5','6','7','8','9','backspace']
  
  # Define all widgets
  button_ok = Button(text=u'Ok')
  #label_gender= Label(u'Your gender')
  checkbox_male = Checkbox(text=u'Male', group=u'gender', var=u'sex')
  checkbox_female = Checkbox(text=u'Female', group=u'gender', var=u'sex')
  label_age = Label(u'Please enter your birthday')
  label_year = Label(u'Year')
  label_month = Label(u'Month')
  label_day = Label(u'Day')
  # Specify a key filter so that only digits are accepted as text input
  input_year  = TextInput(stub=u'2018 …', var=u'byear',  key_filter=filter_digits) #actually a selection thing would be nice
  input_month = TextInput(stub=u'01 …',   var=u'bmonth', key_filter=filter_digits)
  input_day   = TextInput(stub=u'01 …',   var=u'bday',   key_filter=filter_digits)
  
  # Build the form. Specify a validator function to make sure that the form is
  # completed.
  my_form = Form( validator=my_form_validator, cols=3, rows=6, spacing=10, margins=(100, 100, 100, 100),  )
  #my_form.set_widget(label_gender, (0, 0))
  my_form.set_widget(checkbox_male, (1, 0))
  my_form.set_widget(checkbox_female, (2, 0))
  my_form.set_widget(label_age, (1, 1))
  my_form.set_widget(label_year, (0, 2))
  my_form.set_widget(input_year,  (1, 2), colspan=2)

  my_form.set_widget(input_day,   (1, 4), colspan=2)
  my_form.set_widget(button_ok, (1, 5))
  my_form._exec()
  
  # Calculate age from current time and Birtdate
  import shutil,os,datetime
  
  now = datetime.datetime.now()
  current_year  = now.strftime("%Y")
  current_month = now.strftime("%m")
  current_day   = now.strftime("%d")
  #current_time = now.strftime("%Y-%m-%d")
  
  years  = int(current_year) - var.byear
  months = int(current_month) - var.bmonth
  days   = int(current_day) - var.bday
  
  var.age= years + float(months)/12 + float(days)/365
  var.Bday = str(var.byear)+'.'+str(var.bmonth)+'.'+str(var.bday)
  print var.age, var.Bday
  log.write_vars()

  And for those who need an ID_code
  Info: use Bday and ID_code
  a) to check whether a participants participates twice in the same experiment
  b) or whether the same participant participated in two of your experiments

  def ID_code_validator():
  
      """Checks whether all fields have been filled out with one character"""
      #also checks for the number of characters
      return var.X1 != u'no' and var.X2 != u'' and var.X3 != u'' and var.X4 != u'' and len(str(var.X1))==1 and len(str(var.X2))==1 and len(str(var.X3))==1 and len(str(var.X4))==1
  
  ALPHA = []
  for i in range(65,91):
      ALPHA.append(chr(i))
  alpha = []
  for i in range(97,123):
      alpha.append(chr(i))
  list_alphabet = ALPHA + alpha + ['backspace']
  
  def filter_alphabet(ch):
  
      """Allows only alphabetic characters as input"""
  
      return ch in list_alphabet
  
  # Define all widgets
  button_ok = Button(text=u'Ok')
  
  label_father = Label(u'Please enter the first letter of your fathers surname')
  label_mother = Label(u'Please enter the first letter of your mothers surname')
  label_own = Label(u'Please enter the first letter of your own surname')
  label_bplace = Label(u'Please enter the first letter of your birthplace')
  # Specify a key filter so that only digits are accepted as text input
  input_father  = TextInput(stub=u'X …', var=u'X1', key_filter=filter_alphabet) 
  input_mother  = TextInput(stub=u'X …', var=u'X2', key_filter=filter_alphabet)
  input_own     = TextInput(stub=u'X …', var=u'X3', key_filter=filter_alphabet)
  input_bplace  = TextInput(stub=u'X …', var=u'X4', key_filter=filter_alphabet)
  
  # Build the form. Specify a validator function to make sure that the form is
  # completed.
  my_form = Form( validator=ID_code_validator, cols=4, rows=10, spacing=10, margins=(100, 100, 100, 100), )
  #my_form.set_widget(label_gender, (0, 0))
  my_form.set_widget(label_father, (0, 0), colspan=3)
  my_form.set_widget(input_father, (3, 0))

  my_form.set_widget(input_bplace, (3, 6))
  my_form.set_widget(button_ok,    (3, 8))
  my_form._exec()
  
  var.ID_code= var.X1 + var.X2 + var.X3 + var.X4
  print 'ID_CODE:', var.ID_code

  Nice!

  Is there a way to change the fontsize?

  Thanks,

  I always work with these standard settings in the "general options":
  Foreground black
  Background white
  Font mono 18px

  With that it looks nice.

  Apparently changing fontsize is doable:
  http://forum.cogsci.nl/index.php?p=/discussion/507/solved-change-backgrounds-colors-and-fonts-in-widgets

  But for some reasons I struggle to do it, for instance:

  text_OK = "<span font-size = 12 >OK</span>"
  button_ok = Button(text=text_OK)
  

  doesnt seem to work.

  Hey, really helpful advice!

  It doesn't seem like the form_text_input is supported if you want to make an online experiment. Do you have any advice of what to do then?

  Thanks!
