You only need to loop through the query result in the usual fashion and
echo the results within option tags. Here's a function I wrote to to
useful things with SELECT:
<?php
/* formDropDown - create an HTML <SELECT>
* vars: $name - the form variable NAME
* $value - the SELECTED option which may be an array for multiple
selected items
* $labels - assoc. array, list of values=>labels
* $multiple - if non-empty, select multiple
* $size - number of rows to show if multiple
* returns: string, HTML (i.e. for use in echo or print statement) */
function formDropDown($name,$value,$labels,$multiple = '',$size ='') {
$html = '<SELECT NAME="' .$name . '"';
if(!empty($multiple)) {
$html .= ' MULTIPLE';
}
if(!empty($size)) {
$html .= ' SIZE=' . $size;
}
$html .= ">\n";
$key = key($labels);
while($key != "") {
/* Check if the current value is in the $value variable */
if(is_array($value)) {
if(in_array($key,$value)) {
$selected = ' SELECTED';
} else {
$selected = '';
}
} else {
if ($key == $value) {
$selected = ' SELECTED';
} else {
$selected = '';
}
}
$html .= "<OPTION VALUE=\"$key\"$selected>$labels[$key]\n";
next($labels);
$key = key($labels);
}
$html .= "</SELECT>\n";
return $html;
}
?>
