seeking check box auto selecting advice
i have a bunch of check boxes on a control panel. right now i print out what the previous selections were by catagory and only update the ones with new seelctions.
what i want is to modify this so that i can run the print out using the info i get from the db (broken by catagory). so i have a few lists of interests from a greater set in each catagory.
the number of interests (select boxes and titles) displayed per row changes by catagory.
once i echo out the page i don't want to go in and out of php. right now i use heredocs to make the page.
POSIX. because a stable os that doesn't have memory leaks and isn't buggy is always good.

Do you have code we can see?
I'm assuming your using a loop, but I have no idea how you're identifying your pre-selected checkboxes.
<?phpwhile ($checkbox=mysql_fetch_thingy($result)) {
echo \"<input type=\\"checkbox\\" \".($checkbox==$selected?'CHECKED':'').\" />\n\";
}
?>

*noting more efficient coding*
If you're using XHTML, you'll need to report:
checked="checked" or selected="selected" (for select options), not just checked or selected. Just FYI.

<?php
// for use with the echo<<<VAR type of printing
$pprimary_checked = ($form_phone_primary == 'y'?'checked=\"checked\" ':'' );
$ppublic_checked = ($form_phone_public == 'y'?'checked=\"checked\" ':'' );
echo<<<VAR
<input name=\"phone_primary\" value=\"$pid\" type=\"radio\" $pprimary_checked/><br />
<input name=\"phone[$pid][public]\" value=\"y\" type=\"checkbox\" $ppublic_checked/>\n
VAR;
?>
Is there a more efficient way to do this? Obviously there is a chunk of code missing, this is just the part with the checked notation.

In this case, I would avoid using the heredoc syntax. I used to do the exact same thing, but I've changed my opinion on the matter as I now thing it will be slower. This is because you have two extra assignment opperations. (Not that this is some great overhead, but I'm always trying to up my coding standards and habbits)
*moan*

I have the two variables set and then use them all over. Is that less of a burden or more?
I guess part of it is a balance between modularization and efficiency?
For some reason I can never remember heredoc as a name. echo<<<, I remember. Heredoc, nope.
Sorry about the bad news of the XHTML coding, lol.

The speed will be the same, but you'll save memory by reusing the same variables. If you had a huge echo statement, I could see heredoc (echo<<<) being a resonable choice, and in that case, you'd have to use variables.
Something else I've been curious about is are there any speed/load differences (on a very minute scale) between a normal echo() call, and an echo heredoc call (echo<<<). Seems like it would take longer for the interpreter to parse for the heredoc delimiter than it would take for it to handle a quoted string. I've never read any comparison.

i'm trying to use html 4.01 (transitional) here, which i think will let me go either way
i should still alter the select box stuff.
currently the part of the function that prints out the select boxes in the control panel looks like this (some returns included to stop scrrolling):
<?php
function interest(){ # in interests
include(\"/home/joshua/includes/fyd.vars.php\"); # includes file (precautionary measure)
$result; $selections;
$un=$_COOKIE['un']; $pw=$_COOKIE['pw']; # variables to talk to the db
$db=mysql_pconnect('host', 'login', pw) or die(\"cannot access db\"); # connect to the db
$fyd=mysql_select_db('findyourdesire', $db); # get the db
$memfind=mysql_query(\"SELECT * FROM users WHERE username=$un\", $db);
if(mysql_num_rows($memfind)==0){ # problem
echo '<h1>We cannot find you. Are you sure you <a href=\\"join.php\\">Joined?</a>';
}else{ # we found the user
$maininf=mysql_fetch_array($memfind);
$pwc=$maininf['password'];
if($pw!=$pwc){ # cannot verify user
echo \"<p>Cannot verify that you are $un.
Password error (submitted pw does not match file)</p></center></body></html>\";
}else{ # we know who we're dealin with
$uin=$maininf['uid']; $intToUp=''; $selections='';
if(isset($_POST['act'])) { # update the db
# get the submitted information about the interests
$smusic=$_POST['music']; $sbooks=$_POST['books']; $smovies=$_POST['movies'];

Those arrays seem really weird to me. Why repeat it all? For display purposes only?

Repeat what? You mean "key"=>"var" ? I did this so that the name of the input may be different from the description. Generally, I like to keep my input names lower case.
This should also prevent duplicates. Consider this:
$tmp = array('this' => 'that', 'here' => 'there', 'this' => 'those')
$tmp['this'] should now be 'those'.

i want to remove the part where i list out what they previously selected, and have them populated so they can update it that wayit would be easier for the user
