[Plugin: WP-Paginate] query_post parameters are not retained starting from second page

Hi,

The page that I am referring to can be found at:
dev1.invatatenis.ro/terenuri-tenis-camp.

There are 4 posts there – 2 have location Braila and 2 have location Bucuresti. Location is a custom field for posts. There is 1 post per page.

I have a drop down list in which I can filer the posts based on location.
By default, there are 4 pages, a page per post.

If I chose Braila for example, there will be 2 pages, because there are 2 post with Braila. The problem appears here, when I click second page – the second page here is actually the second from all the 4 pages before using the drop down list.

Here is the code that I am using:
$aLocalitati = $wpdb->get_col( $wpdb->prepare(“SELECT DISTINCT (meta_value) FROM wp_postmeta WHERE meta_key=’Localitate'”));
asort($aLocalitati);
//arguments of query posts – default for all localities
$paged = (get_query_var(‘paged’)) ? get_query_var(‘paged’) : 1;
$category = ‘terenuri-tenis-camp’;
$args=array(
‘category_name’=> $category,
‘posts_per_page’=> 15,
‘paged’=>$paged,
);

if(isset($_POST[‘select_location’])) {
$selected_location = $_POST[‘select_location’];
if($selected_location != “all”) {
$args=array(
‘category_name’=> $category,
‘posts_per_page’=> 15,
‘paged’=>$paged,
‘meta_key’=> ‘Localitate’,
‘meta_value’=> $selected_location,
);
}
}
?>
<table>
<tr>
<td style=”padding: 10px;”>Filtreaza dupa locatie:</td>
<td><form name=”location_form” action=”<? echo get_bloginfo(wpurl).’/’.$category;?>” method=”post”>
<select class=”select” name=”select_location” onchange=”this.form.submit();”>
<option value=”all”>Oricare</option>
<?
foreach ( $aLocalitati as $location ) {
if (isset($selected_location) and $selected_location == $location) {
echo ‘<option value=”‘.$location.'” selected=”selected”>’.$location.'</option>’;
} else {
echo ‘<option value=”‘.$location.'”>’.$location.'</option>’;
}
}
?>
</select>
</form>
</td>
</tr>
</table>

<?php
$temp_query = $wp_query;
query_posts($args);

if (have_posts()) :
while (have_posts()) : the_post(); ?> …………

<?php endwhile; ?>
<?php if(function_exists(‘wp_paginate’)) {
wp_paginate();
} ?>
