Hi Stephen,
You might consider offloading the creating of the select to a function call:
function generate_select($name,$option,$sel=0) {
$str = "\
<select name=\\"$name\\">\
";
$str .= "<option value=\\"0\\">- None -</option>\
";
foreach ($option as $key=>$val) {
if ($sel == $val) {
$str .="<option value=\\"$val\\" selected>$key</option>\
";
} else {
$str .= "<option value=\\"$val\\">$key</option>\
";
}
}
$str .= "</select>\
";
return $str;
}
Then, you can just create an array of the values you want in select:
/* I used a numerical representation of the date time to avoid confusion between the key and value */
$arr_times = array( "Friday August 22, 04:00 PM - 06:00 PM"=> "082203_1600_1800", "Friday August 22, 06:00 PM - 08:00 PM"=> "082203_1800_2000");
and run the function like this:
$display_select = generate_select("TimeChoice",$arr_times);
if ($error) {
$display_select = generate_select("TimeChoice",$arr_times,$_POST['TimeChoice']);
}
If you get an error, you will retain the HTTP_POST_VARS for your select value, and you should be in business. Bear in mind I haven't tested this out, but I think it will work; anyone see problems with this?
