Passing GET array variables to page template WordPress


I created a custom search form to filter taxonomies and custom fields meta by make use of wp_query.

The form action is redirect to a custom page template where the custom wp_query running. The search form is using get method to passing the variable.

The form is something like this

<form method="get" id="customsearch" action="<?php echo get_page_link( 12 ); ?>/">//action point to the custom page template

//these are to collect taxonomy data
<input type="hidden" name="taxo[1][name]" value="os">
<input type="text" name="taxo[1][term]" value="">
<input type="hidden" name="taxo[2][name]" value="ram">
<input type="text" name="taxo[2][term]" value="">
<input type="hidden" name="taxo[3][name]" value="cpu">
<input type="text" name="taxo[3][term]" value="">

/these are to collect custom field meta data
<input type="hidden" name="cmf[1][name]" value="place">
<input type="text" name="cmf[1][value]" value="">
<input type="hidden" name="cmf[2][name]" value="price">
<input type="text" name="cmf[2][value]" value="">
<input type="hidden" name="cmf[3][name]" value="software">
<input type="text" name="cmf[3][value]" value="">

<input type="submit" class="submit" value="Search" alt="[Submit]" name="submit" title="Search" />

And i added the variable to query_vars:

add_filter('query_vars', 'my_queryvars' );

function my_queryvars( $qvars )
$qvars[] = 'taxo';
$qvars[] = 'cmf';
return $qvars;

The problem is, when the permalink structure set to default, the form was not redirected to the desired page, instead it went to homepage.

If I set the permalink other structure, like Numeric or Post name, it goes to the correct page, but url broken in paginated page. Eg:
First page:
<blockquote>page_url/page/2/?submit=Search (the GET data stripped)</blockquote>

How do I solve this problem?

Maybe this will help: [[LINK href=""]][[/LINK]] comments:

I tried to add the rewrite rules, but still not working.

This is what I had tried:
function add_author_more_rewrite_rule() {

add_rewrite_rule('page_url/(\d*)$','index.php?taxo=$matches[1]&cmf=$matches[2]', 'top' );


Is this because the variables are in arrays?

Someone else will have to chime in. I was just trying to point you in the right direction. Good luck.

To be able to leave RewriteRule in .htaccess you will need to use them directly in the PHP code, look at the end of this entry:

In your case could be something like this:

add_action('generate_rewrite_rules', 'geotags_add_rewrite_rules');

function geotags_add_rewrite_rules( $wp_rewrite )
$new_rules = array(
'page_url/(.+)' => 'index.php?page_url=' .
$wp_rewrite->preg_index(1) );

/​/​ Add the new rewrite rule into the top of the global rules array
$wp_rewrite->rules = $new_rules + $wp_rewrite->rules;

Tried, but still got no luck.

You have to redirect the template you load as a function of the query_vars you receive in the index.php of your theme. comments:

Sorry I don't quite get what you mean. Are you mean that I need to redirect to my page template page from my homepage?

Francisco Javier Carazo Gil comments:

I would do the next:
1. Do the rewrite as I told you and redirect all to index.php
2. Collect query_vars and if the var you want is set, load your template comments:

Tried also, but still cannot make it right. Anyway, I figured another approach to solve this problem. Now I using pre_get_posts to change the search query. And it work.

Hi there. Have you looked into using the paginate_links() function of WordPress to create your pagination?

See if this code works:

echo paginate_links(array(
'total' => $wp_query->max_num_pages,
'current' => max( 1, get_query_var('paged') ),
'show_all' => true,
'type' => 'list',
'add_args' => $_GET,
'next_text' => '&raquo;',
'prev_text' => '&laquo;'
)) ?> comments:

For some reason, I want to use the default next_posts_link() for the pagination. Anyway, thanks for your suggestion.
