PHP Form Question (Again...)

Question

Sorry for all these questions on PHP validations and such,
but I know you
all enjoy helping!
Anyway - I'm using this bit of PHP code to keep the user's
input inside the
textfields and textboxes when the page is refreshed due to
any errors being
on the page:
value="<?php if(isset($_POST['fieldname'])) echo
htmlentities($_POST['fieldname']);?>"
Or if it's inside a textarea, I just omit the value=" .
Is this possible to do with select boxes? Each time the page
reloads due to
any errors (not filling in all the fields) they all reset to
their default
(first option) and the user has to select them all over
again.
Thanks guys!

Hmmm.... the snippet I posted a few days ago of my php state
select list
function will keep an element's SELECTED value. See the "if
(isset)" lines
down toward the end? Those check for the POSTed status of the
select element
and set the option to selected if it was originally selected.
function stateselectlist() {
$states = array('' => 'Please Select State', 'AL' =>
'Alabama', 'AK' =>
'Alaska', 'AZ' => 'Arizona', 'AR' => 'Arkansas', 'CA'
=> 'California',
'CO' => 'Colorado', 'CT' => 'Connecticut', 'DC' =>
'District of
Columbia', 'DE' => 'Delaware', 'FL' => 'Florida', 'GA'
=> 'Georgia', 'HI'
=> 'Hawaii', 'ID' => 'Idaho', 'IL' => 'Illinois',
'IN' => 'Indiana', 'IA'
=> 'Iowa', 'KS' => 'Kansas', 'KY' => 'Kentucky',
'LA' => 'Louisiana',
'ME' => 'Maine', 'MD' => 'Maryland', 'MA' =>
'Massachusetts', 'MI' =>
'Michigan', 'MN' => 'Minnesota', 'MS' => 'Mississippi',
'MO' =>
'Missouri', 'MT' => 'Montana', 'NE' => 'Nebraska', 'NV'
=> 'Nevada', 'NH'
=> 'New Hampshire', 'NJ' => 'New Jersey', 'NM' =>
'New Mexico', 'NY' =>
'New York', 'NC' => 'North Carolina', 'ND' => 'North
Dakota', 'OH' =>
'Ohio', 'OK' => 'Oklahoma', 'OR' => 'Oregon', 'PA'
=> 'Pennsylvania', 'PR
'=> 'Puerto Rico', 'RI' => 'Rhode Island', 'SC' =>
'South Carolina', 'SD'

'Texas', 'UT' => 'Utah',
'VT' => 'Vermont', 'VA' => 'Virginia', 'WA' =>
'Washington', 'WV' =>
'West Virginia', 'WI' => 'Wisconsin', 'WY' =>
'Wyoming');
$str = "<select name=\"state\" id=\"state\">\n";
foreach ($states as $key => $value) {
$str .= "<option value=\"$key\"";
if (isset($_POST['state']) && ($key ==
$_POST['state']) ) {
$str .= 'selected="selected"';
$str .= ">$value</option>\n";
$str .= "</select>\n";
return $str;
} // END function stateselectlist
