I use the following
Looks a bit unwieldy to call, but does everything I need.
eg, say I have a table called foo with ID, Name
print OptionCreate ("ID","returnID", "foo order by Name", "","Name");
will create me a drop down
print OptionCreate ("ID","returnID", "foo order by Name", "1","Name");
will create me a drop down with item 1 selected.
Hope this helps.
//OptionName = field to list, passedname=option Select name
//tablename= table name , selected value = option select selected value if
found
//NOTE THAT THE DB open MUST have been already made in the calling
routine!!!
//eg $db = mysql_connect($db_domain, $db_user,$db_password);
// mysql_select_db($db_databasename,$db);
function OptionCreate ($optionname,$passedname, $tablename,
$selectedvalue="",$optiontext="") {
if ($optiontext=="")
$sqlstring = "select $optionname from $tablename";
else
$sqlstring = "select $optionname, $optiontext from
$tablename";
global $db;
$result=mysql_query($sqlstring,$db);
$rows = mysql_num_rows ($result);
$tmpOut = "<select name=\"$passedname\" size=1>";
for ($count=0;$count <$rows; $count++) {
$tmpOut = $tmpOut . "<option value=\"" .
MYSQL_RESULT($result,$count,$optionname) . "\"";
//Select item if passed variable is found
if ($selectedvalue ==
MYSQL_RESULT($result,$count,$optionname))
$tmpOut=$tmpOut . "selected";
if ($optiontext=="")
$tmpOut = $tmpOut . ">" .
MYSQL_RESULT($result,$count,$optionname) . "</option>";
else
$tmpOut = $tmpOut . ">" .
MYSQL_RESULT($result,$count,$optiontext) . "</option>";
}
$tmpOut = $tmpOut . "</select>";
return ($tmpOut);
}

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;
}
?>
