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
9th">September 9th
<input name="gmev[]" type="checkbox" id="gmev" value="October
14th">October
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 $checked value in the echo string
will
always show
the button "checked" So no matter what is selected, it comes back to
"checked"
Any suggestions?
HTML is:
<input name="member" type="radio" value="Yes" checked> Member
I assume that should be?:
<input name="member" type="radio" value="Yes" checked="checked"> Member
<input name="member" type="radio" value="No">Prospective Member
PHP is:
<?
if ($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...

I am new to php and am in need of some guidance
I am building a sticky form and am having trouble bringing in the
data
sticky as in honey?
fields for
checkbox's and radio button's. Any help on how to do this would be
appreciated
HTML form sample
<input name="gmev[]" type="checkbox" id="gmev" value="September
9th"></th>
PHP
<input name="gmev[]" type="checkbox" id="gmev" value="<? echo
$gmev_day
?>"></th>
am I on the right track here?
maybe, partially - generally radio buttons and checkboxes have fixed
values -
it's the 'are they selected' part that probably want to make
dynamic...
basically you need to conditionally add the attribute 'checked' (i.e.
checked="checked") to the radios and checkboxes you want selected when
the
form is first shown.
e.g.
<?
if ($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.
