==============================================

In my webpage here http://superhost.gr/hosting.html i ask the users
mail and comment in a html form.

No matter what info the user gives after he submits the form, nothing
else happens instead of reloading the page itself while what i want
the code to do is to enter the if structure and display the
appropriate message, depending if the user entered data in the imput
box or not.

Am i missing something here?

Do you really want to look for the comment in that string instead of
looking for that string in the comment?

What do you mean?

I just want to check that the user hasnt pressed the submit button
leaving the default values with the input comment box.

Iam not sure what you mean.

In the first part of the condition you're asking:

     '@' in mail

which is OK, but in the second part of the condition you're asking:

     comment not in ("Ρωτήστε με σχετικά...")

which I think should be:

     "Ρωτήστε με σχετικά..." not in comment

Incidentally, it looks to me like you're using Python 2, in which case
it's probably a good idea to use Unicode, so that would be:

     u"Ρωτήστε με σχετικά..." not in comment

and so forth.

Ah yes i have had them reversed!

I corrected that now but still if the user submits the form by not
entering any input all the program does is reloads itself.

So the question now is why the program flow doesn't enter the if code
block since its conditions are met?

ps. http//superhost.gr/hosting.html is now http//superhost.gr/
directly.

I've made some progress,

here is a part of index.html:
=====================================================================================
<form method="post" action="..\index.html">

<input type="text" name="mail" value="To mail σου?"><br>
<textarea name="comment" cols="30" rows="5">
Ρωτήστε σχετικά...
</textarea><br>

<input type="hidden" name="page" value="index.html">
<input type="hidden" name="ok" value="pressed">

<input type="submit" value="ΟΚ">

</form>
=====================================================================================

and here is a part of counter.py:

=====================================================================================
# insert guest comments into database if form was submitted
if ('@' in mail) and ("Ρωτήστε σχετικά..." not in comment):
    try:
	cursor.execute( '''INSERT INTO users(mail, comment) VALUES(%s,
%s)''', (mail, comment) )
    except MySQLdb.Error, e:
    print ( "Error %d: %s" % (e.args[0], e.args[1]) )

    print ( "<h2><font color=blue>Ευχαριστώ για την ερώτηση! Θα σας
απαντήσω το συντομότερο δυνατό!" )
    sys.exit(0)
elif (ok == 'pressed') and ('@' not in mail or comment == ''):
    print ( "<h2><font color=red>Συμπλήρωσε σωστά το mail σου και δώσε
το σχολιασμό σου!" )
    sys.exit(0)
=====================================================================================

Is there a way to check 'mail' and 'comment' variables for emptyness
and '@' not in mail
without passing the value of 'pressed' to the hidden field 'ok'?


Also are the above html statements the same?

<form method="post" action="..\index.html">

<form method="post" action="">      <= Does it implies to run itself?
