WordPress Custom Field Search.

[Ted]

Hi there!
I guess this is the only place i can get some answers …

Well i have developing a wordpress website… and i am using alot of custom fields…and they have worked very good until i needed to create a filter/search from using them …
so far … not good… i had used plugins to create it but they are not that flexible …
i am not used to do this… so can any one help me!?

The idea:

get custom fields to combobox
do a search by the selects.

The Code:
i have done this ( not working …. )

( cicle to get all the costum fields names )
<?php
global $post;
$tmp_post = $post;
$myposts = get_posts(‘child_of=1’);
foreach($myposts as $post) :
setup_postdata($post);
?>
<?php $option[] = get_post_meta($post->ID,’Concelho’, true);
$Concelho=array_unique($option); sort($Concelho); ?><!–Concelho–>
<!–Tipo de Imovel –>
<?php $old_estado[] = get_post_meta($post->ID,’Estado’, true);
$estado=array_unique($old_estado); sort($estado); ?><!–Estado –>

<?php $old_quartos[] = get_post_meta($post->ID,’Quartos’, true);
$quartos=array_unique($old_quartos); sort($quartos); ?><!–Quartos–>

<!–Preço minimo –>
<?php $old_preco[] = get_post_meta($post->ID,’Preco’, true);
$preco=array_unique($old_preco); sort($preco); ?><!–Preço minimo –>

<!–Preço maximo –>
<?php $old_referencia[] = get_post_meta($post->ID,’Referencia’, true);
$referencia=array_unique($old_referencia); ?><!–referencia –>

<?php endforeach; ?>

( form )

<form role="search" method="get" id="searchform" action="<?php bloginfo(‘siteurl’); ?>">
<div>
<?php
$cbox = ‘<select name="Concelho" style="width:291px; height:25px; text-align:left; font-size:9pt; padding-top:3px; margin-top:10px;">’;
foreach($Concelho as $key=>$val) :
$cbox .='<option value="’.$val.’" selected="false">’.$val.'</option>’;
endforeach;

$cbox .='<option value="" selected="true" >’.Seleccione." ".o." ".Concelho.'</option>’;
$cbox .= ‘</select>’;
echo $cbox;
?>

<input type="submit" id="searchsubmit" value="Search" />
</div>
</form>
