Maybe it's just me, but using the name of a global as a function
parameter just seems like a bad idea. Yes, you can do it. Should you?
I think not. Especially, as, you are passing it a scalar below and
treating it here like the global array.
//Make sure to post form start/stop OUTSIDE of this function...
//It's not meant to be a one size fits all function!
echo "NAME: " . $name . "<BR>";
echo "MESSAGE: " . $message . "<BR>";
echo "POST: " . $_POST . "<BR>";
echo "OPTION: " . $option . "<BR>";
$sticky = '';
if(isset($_POST['submit'])) {
Check the error messages -- since you're passing in $startYear as a
scalar below, you shouldn't be able to access $_POST as an associative
array.
$sticky = $_POST["{$name}"];
echo "STICKY: " . $sticky;
}
//echo "OPTION: ";
//print_r($option);
echo <<<HTML
<select name="{$name}">
<option value="0">{$message}</option>
HTML;
foreach ($option as $key => $value){
if($key == $sticky) {
echo '<option value="' . $key .'" selected>' . $value . '</option>';
}else{
echo '<option value="' . $key .'">' . $value . '</option>';
}
}
echo <<<HTML
</select>
HTML;
unset($value);
return;
}

One for Month, Day & Year... All the same exact code... When I get
brave I'll combine it into 1 functions :)
Now... What it's trying to do.. It's on a "update" form on my
website. Basically pulls the info from the database and displays it
in the form again so it can be edited and resubmitted...
As I'm sure you can tell from the function it checks to see if the a
value has been selected in the drop down box and if it has then set
the drop down box to that value.
I call the function like this:
<?PHP
$startYear = date("Y", $row['startdate']); //Actual DBValue:
1265000400
You're setting $startYear as a scalar value here.
$optionYear = array("2010" => "2010", "2011" => "2011", "2012" =>
"2012", "2013" => "2013", "2014" => "2014");
ddbYear("startYear", "Select Year", $startYear, $optionYear);
And passing it in to the $_POST variable in your function. Then you
treat the $_POST variable as an associative array (seemingly much like
the global $_POST array).
?>
The output I'm getting is:
THESE ARE THE ACTUAL UNPROCESSED (OTHER THEN SEPARATING) VALUES FROM
THE DATABASE
startmonth: 2
startday: 1
startYear: 2010
endmonth: 11
endDay: 30
endYear: 1999
THESE ARE THE VALUES INSIDE THE FUNCTION
NAME: startYear
MESSAGE: Select Year
POST: 2010
OPTION: Array
STICKY: 2
Now... The problem is that $sticky get set to "2" instead of
"2010"... But I can't figure out why...
Anyone have any ideas?
And just incase I didn't provide enough info here's a link that
shows it happening:

id=62
Again, I will reiterate that taking the name of a global variable and
using it as a parameter in a function is a bad idea. It can be done,
and my in some cases have some uses, but I don't think the way you're
using it is a good idea, and looks wrong to me as well.
