Hi all
I am making something for my webpage
Where the user can choose a month: I have made that with a dropdown box.
<select>
<option name = "1" value="1">Janua ry
<option name = "2" value="2">Febru ary
<option name = "3" value="3">March
<option name = "4" value="4">April
<option name = "5" value="5">May
<option name = "6" value="6">June
<option name = "7" value="7">July
<option name = "8" value="8">Augus t
<option name = "9" value="9">Septe mber
<option name = "10" value="10">Octo ber
<option name = "11" value="11">Nove mber
<option name = "12" value="12">Dece mber
</select>
The thing is:
I also want the user to choose a date
I will make this with another dropdownbox.
But if the first month is selected, then there should be 31 days in the days
dropdownbox, if the second month is selected there should be 28 days in the
dropdownbow.
I Know a little of python programming, but not to much, I have a feeling of
that I should use a cgi, can any explain me what I have to do :? Or give me
a link to a site where I can copy the code for it
All help will be greatly appreciated.
Thanks for your time 15 1711
If I understand what you are asking then Python & CGI are a poor
solution. It would be easy to have one page ask for the month, click
submit, then have a second page ask for the exact date. Easy; but
terrible design.
You want to have one page with a dropdown of months. When you select a
month, you want to dynamicly alter a dropdown of dates without
refreshing the page.
For this task you'll want to pull JavaScript out of your toolbox. This
is a fairly common "problem" and googling for examples/samples should
be quick-n-easy.
Thanks.
Do you know what I should google after, which key words ?
regards...

An improvement is to just have the dropdown listbox go from 1 to 31,
and if the user enters an invalid date, give them an error message and
ask them to re-enter the date.

What if the year is 2004? Then I assume you want 29 days in the listbox.
And that, of course, means they have to choose the year first.
This can be done, but it's a lot of trouble. You might consider allowing 1
to 31 and validating the numbers in your "onSubmit" handler.
Or, even better, skip the listbox and just let me type the damn numbers
myself. I hate being forced to fall back to my mouse to type in a date,
when I can type "3 tab 25 tab 2005" much quicker. To do that with your
code, I have to type "m tab 2 2 2 2 2 2 tab 2005".
As an alternative, there are Javascript-based mini-calendars you can
download that popup a little window with the current month, and let you
click on the date.

Hi.
Yeah I also like just to be able to write in numbers.
That is how it works right now.
But then I will have to make some code, that validates if the day number is
higher than allowed.
Like if it is January, the days arnt allowed to be higher than 31.
Will one be so kind and explain how I write that code:
Right now, the user has to put the data into a form:
print '''<form action='inserte vent.py'><br>
<p>Title :<br> <INPUT type="text" NAME="title">
<p>Month (1-12):<br> <INPUT type="text" NAME="month">
<p>Day (1-31):<br> <INPUT type="text" NAME="day">
<p>Start (00.00):<br> <INPUT type="text" NAME="start"></p>
<p>End (00.00):<br> <INPUT type="text" NAME="eventend" ></p>'''
print '''<p><input type=submit value='Submit'> </p></form>'''
print '''</body> </html>'''
Then it runs the insertevent.py script, which puts the data into my
database.(Using postgresql)
form = cgi.FieldStorag e()
title = form["title"].value
month = form["month"].value
day = form["day"].value
start= form["start"].value
eventend = form["eventend"].value
insert_command = "INSERT INTO events1(title, maanedid, dage1id, start,
eventend) VALUES('%s', '%s', '%s', '%s' , '%s')" %(title, month, day, start,
eventend)
cur.execute(ins ert_command)
insert_command2 = "SELECT events1.eventsi d FROM events1 WHERE events1.title
= '%s' AND events1.maanedi d = '%s' AND events1.dage1id = '%s' AND
events1.eventst art = '%s' AND events1.eventen d = '%s'" %(title, month, day,
eventstart, eventend)
cur.execute(ins ert_command2)
res = cur.fetchall()
new_idevents = res[0][0]
insert_command3 = " INSERT INTO evr1 (eventsid, maanedid, dage1id) VALUES
( '%s', '%s', '%s')" %(new_idevents, month, day)
cur.execute(ins ert_command3)
connect.commit( )
cur.close()
connect.close()
print "<br>Arrangemen etet er nu oprettet."
print "</form></body> </html>"
Im which scritp, and how do I make an error message if the day is out of
range.
It is prolly something like:
if month = 1
then days have to be >1 and < 32
else print " day entered out of range"
if month = 2
and so on...
Thanks for all your help, somehow it just makes more sense when I see it, I
am still new to the whole code thing :)
Thanks

Just use the datetime module:
Python 2.4.1a0 (#2, Mar 1 2005, 15:45:39)

Type "help", "copyright" , "credits" or "license" for more information. from datetime import date date(2004, 2, 29)
datetime.date(2 004, 2, 29) date(2005, 2, 29)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: day is out of range for month
/patrik
get the mx package here: http://www.egenix.com/files/python/e...ownload-mxBASE
=============== =============== =========== import mx.DateTime print mx.DateTime.Dat eTime(2004,2,31 ) # Feb. 31?
Traceback (most recent call last):
File "<stdin>", line 1, in ?
mx.DateTime.Ran geError: day out of range: 31
Hi and thanks for the replies.
It is starting to make a little sense. But its still not that clear...
If I import the DateTime or install and import the mx package.
Where should I then change something in my code?
I guess that I will have to see if the entered number is valid when the user
clicks the submit button.
So it must be when I run my insertevent.py script.
So will I have to import the DateTime modul in my form.script or in my
insertevent.scr ipt
And this maybe sound stupid, but will one pls give me an example of what the
code could be for maybe January and February.
I just cant figure out how they work together, the DateTime modul and the
html form.
The user can enter a number in the month field and in the day field. Then
there have to be a tjeck to see if the entered numbers are valid. If the
number entered in the month field is 1 and the number entered in the day
field is 32, there have to come anerror report, and the user will get a
second try to enter the right numbers.
And then if the entered numbers are correct, the data will be inserted in
the database ( But I will work on this if condition myself, I think I can
figure that out:)
So it is just the tjeck to see if the entered numer are valid, I need help
with.
Thanks for all help, it is highly appreciated, and helps me to understand
this new strange but fascinating world of programming.

really good tutorial on exceptions. The whole book is well done, in
fact, I recommend it. I also like Practical Python, and the Oreilly
"Learning Python", but they're not online.
For production purposes, you'd still do date-check on the client
(javascript) but you must do the check server-side nevertheless. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
