I use a function to create select boxes:
function make_select($fieldname,$options,$selected,$opt="") {
# make a select box with option text $opt
# $fieldname = name of html field
# $options = associative array of select options
# $selected = field key of selected item
# $opt = optional attributes, e.g., styles, etc.
$output.="\n<select name=\"$fieldname\" $opt >";
foreach ($options as $key=>$val) {
$output.="\n<option value=\"$key\"";
if ($key==$selected) {
$output.=" selected";
}
$output.=">$val";
}
$output.="\n</select>\n";
return $output;
}
By passing the previously selected item as $selected it will
automatically reselect the chosen item. For instance,
<?php echo make_select("myfield",$options,$_POST["myfield"]) ?>
I've written similar functions for check boxes and radio buttons.
They've made form creation and handling enormously easier.
