I see that you have a nested <option ...> tag. Maybe you are looking for the
<optgroup> tag.
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
<?php
$categories[] = array('id' => 1, 'name' => 'cars');
$categories[] = array('id' => 2, 'name' => 'trucks');
$categories[] = array('id' => 3, 'name' => 'motorcycles');
$pages[] = array('id' => 1, 'name' => 'Neon', 'cat_id' => 1);
$pages[] = array('id' => 2, 'name' => 'Saturn', 'cat_id' => 1);
$pages[] = array('id' => 3, 'name' => 'F150', 'cat_id' => 2);
$pages[] = array('id' => 4, 'name' => 'Ram 2500', 'cat_id' => 2);
$pages[] = array('id' => 5, 'name' => 'Suzuki', 'cat_id' => 2);
$pages[] = array('id' => 6, 'name' => 'Honda', 'cat_id' => 3);
echo "<select id=\"page_id\">\n";
foreach ($categories AS $cat) {
$c_cat_name = htmlspecialchars($cat['name']);
echo "\t<optgroup label=\"{$c_cat_name}\">\n";
foreach ($pages AS $page) {
if ( $page['cat_id'] == $cat['id'] ) {
$c_page_id = htmlspecialchars((int)$page['id']);
$c_page_name = htmlspecialchars($page['name']);
echo "\t\t<option value=\"{$c_page_id}\">{$c_page_name}</option>\n";
}
}
# Reset pages so you can loop through it again
reset($pages);
echo "\t</optgroup>\n";
}
echo "</select>\n";
?>
All the above is untested, but should get you very close to what I think you are
trying to accomplish.
