thanks Jochem -
I am learning alot about arrays.
I think this may be what i am looking for
if (in_array('September 9th', $gmev)) it seems to work great...
is that $gmev being created automatically? if so you are
using register_globals - which is one step in the direction of the
dark side - for the love of insert preferred god/icon/hero/etc use
the element in the $_POST superglobal array instead i.e.
$_POST['gmev']
However...when you get one problem solved, another pops up...
not problems - challenges.
The checkboxes work as long as one is selected, but
if the page is submitted without checking any boxes in the array..
you get the warning
Warning: in_array(): Wrong datatype for second argument
it wants an array - your not giving it an array.
Any idea on how to resolve this?
how do you think it should be resolved? what about checking the variable
before blindly using it - time to find a way to check if a var is an array
(or even exists in the scope of the current code) ... there is a function
that does this - it's name is so selfevident that I'm not even going to name it
- seek and you shall find.
Thanks,
Zedleon

ok, thanks again Jochem!
Its good to know their is support for php from good people like you.
The radio's are working great! However i still have a small issue with
the
checkboxes..
They appeared to be working properly...but now all the checkboxes in the
array are checking
Not sure whats going on...I can tell you this however..my brain in mush.
here is what i have...
HTML is:
input name=gmev[] type=checkbox id=gmev value=September
9thSeptember 9th
input name=gmev[] type=checkbox id=gmev value=October
14thOctober
14th
input name=gmev[] type=checkbox id=gmev value=November 11th
November 11th
input name=gmev[] type=checkbox id=gmev value=December 9th
December 9th
PHP looks like this:
?
if ($_POST['gmev']) {
$_POST['gmev'] will be an array - you have to loop it
and determine which of the date values (from the checkboxes)
it contains - for each date found you have to set the
corresponding checkbox.
its time to learn about associative arrays, using
array indexes and foreach loops!
$checked = ' checked=checked';
} else {
$checked = '';
}
echo 'input name=gmev[] type=checkbox id=gmev',$checked,'/';
?
any Idea's
Thanks in advance

Jochem,
Thanks for your help...I can see your a great PHP programmer.
flattery gets you everywhere - even if it isn't true.
I'm not that bad - but lets leave the 'great' for those that really
are -
you know people who develop/invent the actual language - people who
write books about it, people like that :-)
oh and as long as it's php related make sure to atleast cc the list.
The dynamic checkbox code you sent worked great!
I am however have a problem with a set of radio buttons...
I am trying to appy the same principle here...
The problem I am encountering is the $checked value in the echo string
will
always show
the button checked So no matter what is selected, it comes back to
checked
Any suggestions?
HTML is:
input name=member type=radio value=Yes checked Member
I assume that should be?:
input name=member type=radio value=Yes checked=checked Member
input name=member type=radio value=NoProspective Member
PHP is:
?
if ($member) {
if $member containseither 'Yes' or 'No' then it will equate to boolean
true - which is what you are in fact testing
try something like:
if ($member == 'Yes') {
$checked = ' checked=checked';
} else {
$checked = '';
}
echo 'input name=member type=radio',$checked,'/';
?
Thanks for the help...

not wanting to go down the path of the darkside...I inserted the
superglobals..
if (isset($_POST['gmev']) in_array('September 9th', $_POST['gmev']))
so did I get it right?
there are many roads to Rome. using isset() and in_array() is a
very good start indeed! (you'd be surprised at how many people don't check
vars at all) you might consider either casting $_POST['gmev']
as an array at some stage:
$myArr = (array)$_POST['gmev']
or also using is_array() to check that $_POST['gmev'] is actually an array.
another technique sometimes used is to suppress the error in cases when
you need speed AND you know the error is of no consequence:
if (@in_array('September 9th', @$_POST['gmev'])) {
// bla
}
notice 2 @ signs. the first suppresses the warning about possible in correct
2nd param to in_array() the second will suppress the notice if $_POST['gmev']
is not set.
be very wary of the @ sign - don't use it lightly, most always using isset()
in combination with a is_*() function is much much better (and more correct.
also check out the ctype functions:

it's the 'are they selected' part that probably want to make dynamic...
basically you need to conditionally add the attribute 'checked' (i.e.
checked=checked) to the radios and checkboxes you want selected when the
form is first shown.
e.g.
?
if ($thisChkBoxIsInitiallySelected) {
$checked = ' checked=checked';
} else {
$checked = '';
}
echo 'input name=gmev[] type=checkbox id=gmev',$checked,'/';
?
of course there are a million different ways to write this kind of thing
(i.e. don't take my example verbatim perse) but hopefully you get the
idea.
