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.

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 zed ----- Original Message ----- From: "Jochem Maas" <jochem@iamjochem.com> To: "Ted Passey" <tlp@passeycorp.com>; "[php] PHP General List" <php-general@lists.php.net> Sent: Friday, August 12, 2005 1:09 PM Subject: Re: [PHP] making checkbox's and radio buttons sticky

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... zed ----- Original Message ----- From: "Jochem Maas" <jochem@iamjochem.com> Newsgroups: php.general To: "zedleon" <support@passeycorp.com> Cc: <php-general@lists.php.net> Sent: Thursday, August 11, 2005 9:18 PM Subject: Re: [PHP] making checkbox's and radio buttons sticky

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

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.
