Hacking form.mini.phtml – list all options of an attribute

So I needed a slightly customised advanced search for a client.  Really I just needed 1 attribute and prices to be searchable from every page on the site.

<?php
$catalogSearchHelper = $this->helper('catalogsearch');
?>
<?php $maxQueryLength= $this->helper('catalogsearch')->getMaxQueryLength();?>
<form id="search_mini_form" action="<?php echo $this->getUrl('catalogsearch/advanced/result/');?>" method="get">
<input type="hidden" name="order" value="relevance">
<input type="hidden" name="dir" value="desc">
 <div class="header-search">
 
 <!-- This is the original Search field
 <input id="search" type="text" name="<?php echo $catalogSearchHelper->getQueryParamName() ?>" value="<?php echo $catalogSearchHelper->getEscapedQueryText() ?>" class="input-text" maxlength="<?php echo $catalogSearchHelper->getMaxQueryLength();?>" />
 -->
 
 <label for="bedrooms">Number of Bedrooms:</label>
 <select name="bedrooms[]" >
<?php
$name='bedrooms';
$attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'bedrooms'); // attribute code here
 foreach ( $attribute->getSource()->getAllOptions(true, true) as $option)
 {
 echo '<option value="'.$option['value'].'">'.$option['label'].'</option>';
 } 
?> 
 </select>
 <label for="price[from]">Minimum Price:</label>
 <label for="price[to]">Maximum Price:</label>
 <select name="price[from]" id="minimum">
 <option value="">No Minimum</option> 
 <option value="100000">&pound;100,000</option> 
 <option value="125000">&pound;125,000</option> 
 <option value="150000">&pound;150,000</option> 
 <option value="175000">&pound;175,000</option> 
 <option value="200000">&pound;200,000</option> 
 <option value="225000">&pound;225,000</option> 
 <option value="250000">&pound;250,000</option> 
 </select>
 <select name="price[to]" id="maximum">
 <option value="">No Maximum</option> 
 <option value="100000">&pound;100,000</option> 
 <option value="125000">&pound;125,000</option> 
 <option value="150000">&pound;150,000</option> 
 <option value="175000">&pound;175,000</option> 
 <option value="200000">&pound;200,000</option> 
 <option value="225000">&pound;225,000</option> 
 <option value="250000">&pound;250,000</option> 
 </select>
 
 <button type="submit" title="<?php echo $this->__('Search') ?>" value="Search Properties" class="search-btn">Search Properties</button>
 <div id="search_autocomplete" class="search-autocomplete"></div>
 <script type="text/javascript">
 //<![CDATA[
 var searchForm = new Varien.searchForm('search_mini_form', 'search', '<?php echo $this->__('Search Amethyst Homes...') ?>');
 searchForm.initAutocomplete('<?php echo $catalogSearchHelper->getSuggestUrl() ?>', 'search_autocomplete');
 //]]>
 </script>
 </div>
</form>
