Do test this, but I think all that's required is you make the name an array:
<select name="DPRpriority[]" form="DPRform">

Something like this?
if $DPRpriority[0] == "7. Morality / Drugs" { echo "selected"; }
I hate arrays. :D

<?php
$DPRpriority[] = array(

"1" => "b",
1.5 => "c",
true => "d",
);
var_dump($array);
?>

Not exactly that -- I think I goofed up your variable names.
$DPRpriority is the set of values that can be selected, and DPRType
are the values returned from the form.
Here's a small snippet showing how it works, I hope:
<?php
// Initial value for demo
$DPRpriority = array(array('name' => "Crimes Against Persons",
'selected' => false),
array('name' => "Disturbances", 'selected' => false),
array('name' => "Assistance / Medical", 'selected' =>
false),
array('name' => "Crimes Against Property", 'selected' =>
false),
array('name' => "Accidents / Traffic Problems", 'selected'
=> false),
array('name' => "Suspicious Circumstances", 'selected' =>
false),
array('name' => "Morality / Drugs", 'selected' => false),
array('name' => "Miscellaneous Service", 'selected' =>
false),
array('name' =>"Alarms", 'selected' => false));
echo "<h1>Initial value of DPRpriority:</h1><ul>\n";
foreach ($DPRpriority as $item => $value) {
echo "<li> ".$item.": ".$value['name']." selected:
".$value['selected']." </li>\n";
}
echo "</ul>\n";
if (count($_POST) > 0) {
// something was posted:
echo "<h1>\$_POST:</h1><pre><code>\n";
var_dump($_POST);
echo "</code></pre>\n";
echo "<h2>Items selected:</h2><ul>\n";
foreach ($_POST['DPRType'] as $item) {
$DPRpriority[$item]['selected'] = true;
echo "<li>".$item.": ".$DPRpriority[$item]['name']."</li>\n";
}
echo "</ul>\n";
echo "<h1>Final value of DPRpriority:</h1><ul>\n";
foreach ($DPRpriority as $item => $value) {
echo "<li> ".$item.": ".$value['name']." selected:
".$value['selected']." </li>\n";
}
echo "</ul>\n";
}
?>
<form method="post">
<select name="DPRType[]" id="DPRType[]" multiple onchange=""
size="<?php echo count($DPRpriority) ?>">
<?php foreach ($DPRpriority as $index => $value) { ?>
<option value="<?php echo $index; ?>"<?php if ($value['selected'])
{echo ' selected="selected"';} ?>><?php echo
$value['name'];?></option>
<?php } ?>
</select>
<input type="submit" name="submit" value="submit" />
</form>

Here's a small snippet showing how it works, I hope:
foreach ($DPRpriority as $item => $value) {
echo "<li> ".$item.": ".$value['name']." selected:
".$value['selected']." </li>\n";
}
Question 1: when did we have to add [] to a <input> name to turn it into
an array?
<input type="checkbox" name="DPRlocationdetails[]" value="Unknown">
According to phpinfo() it still comes out as
$_POST['DPRlocationdetails'] without [].
Are the [] necessary?
----------------------------------------------
Question 2:
I was looking at some code in the Manual, where someone used isset and
is_array.
How necessary is if(isset($_POST['DPRlocationdetails']))
and then to use: if(is_array($_POST['DPRlocationdetails']))
That seems like over kill?
----------------------------------------------
Question 3:
My code works, perfectly. In this case, I decided to attack some
check-boxes first. The resulting function will work for <select
multiple> too..
Does anyone see me doing something wrong in my code below?
My questions are:
Is this the only way to pass "Unknown", "Family Home" or "Apartment"
into the function?
Is this correct?
---- if ($_POST['DPRlocationdetails'] == "Unknown")
Somebody once told me I had to do it this way?
---- if ("Unknown" == $_POST['DPRlocationdetails'])

<form action="foo.php" id="DPRform" method="post"><input value="Update"
type="submit">
<input type="checkbox" name="DPRlocationdetails[]" value="Unknown" <?php
filter_value($_POST['DPRlocationdetails'],"Unknown"); ?>> Unknown
<input type="checkbox" name="DPRlocationdetails[]" value="Family Home"
<?php filter_value($_POST['DPRlocationdetails'],"Family Home"); ?>>
Family Home
<input type="checkbox" name="DPRlocationdetails[]" value="Apartment"
<?php filter_value($_POST['DPRlocationdetails'],"Apartment"); ?>> Apartment
</form>
<?php
function filter_value($tofilter,$tofind) {
foreach($tofilter as $value){
if ($value == $tofind) echo "checked";
}
}
?>
