Doesn't work

Can’t tell what is the problem from your question. There are so many causes.

Possibilities:
1. You posts don’t have the custom meta and taxonomy that you created in search form.
2. Wrong post type choose.
3. Plugin conflict.

It was indeed a plugin conflict, specifically the search plugin Relevanssi. I guess I’ll look for another alternative for post sorting because Advance WP Query Search Filter has some great features I wanna keep.

using wp 3.8.1 with wp advanced search 2 , the problem come when i made the change in the SEARCH.PHP and SEARCHFORM.PHP doing has it was suggested by the author.

NOTE THAT FOR THE TEST I HAVE DISACTIVATE ALL PLUGINS EXCEPT ADVANCED SEARCH…

i can login has administrator but i cant see the site’s post and pageS anymore,,nothing, just the graphic

i use twentyeleven template,

this is my searchform
<?php
<div id=”formulaire-recherche”>
<form method=”get” id=”searchform” action=”<?php bloginfo(‘url’); ?>”>
<div id=”recherche”>
<input type=”text” name=”s” id=”s” value=”” />
<input type=”submit” value=”OK” id=”bouton” />
</div>
</form>
</div>
?>
cause i keep “s” as id

and this is 2 model of the search.php form

1st MODEL /////////////////////

/**
* The template for displaying Search Results pages.
*
* @package WordPress
* @subpackage Twenty_Eleven
* @since Twenty Eleven 1.0
*/

get_header(); ?>
<div id=”content”>
<div id=”colleft”>
<?php WP_Advanced_Search(); ?>
<div id=”colright”><?php get_sidebar(); ?></div>
<p class=”clear”></p>
</div>
</div>

<?php get_footer(); ?>

2ND ) ////////////////////////THIS IS THE ORGINAL SEARCH EXECPT THE LOOP WAS REPLACED BY THE <?php WP_Advanced_Search(); ?>

BUT PUTTING BACK THE 2 ORIGINAL FILES AND THE SITE RUN HAS BEFORE..
THE PLUGIN IS ACTIVE

<?php
/**
* The template for displaying Search Results pages.
*
* @package WordPress
* @subpackage Twenty_Eleven
* @since Twenty Eleven 1.0
*/

get_header(); ?>

<section id=”primary”>
<div id=”content” role=”main”>

<?php if ( have_posts() ) : ?>

<header class=”page-header”>
<h1 class=”page-title”><?php printf( __( ‘Search Results for: %s’, ‘twentyeleven’ ), ‘<span>’ . get_search_query() . ‘</span>’ ); ?></h1>
</header>

<?php twentyeleven_content_nav( ‘nav-above’ ); ?>

<?php /* Start the Loop */ ?>
<?php WP_Advanced_Search(); ?>

<?php twentyeleven_content_nav( ‘nav-below’ ); ?>

<?php else : ?>

<article id=”post-0″ class=”post no-results not-found”>
<header class=”entry-header”>
<h1 class=”entry-title”><?php _e( ‘Nothing Found’, ‘twentyeleven’ ); ?></h1>
</header><!– .entry-header –>

<div class=”entry-content”>
<p><?php _e( ‘Sorry, but nothing matched your search criteria. Please try again with some different keywords.’, ‘twentyeleven’ ); ?></p>
<?php get_search_form(); ?>
</div><!– .entry-content –>
</article><!– #post-0 –>

<?php endif; ?>

</div><!– #content –>
</section><!– #primary –>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

//////////////////////////////////////
so what can i do now..the theme used is running perfectly with a 20 active plugins yet and no problemo. but with these searchform nothing run anymore

help will be appreciate

sorry, made a big mistake,..after reading again, it was more simple than the way i understood,

i check name and id (s)

and put <?php WP_Advanced_Search(); ?> after deleting all the <?php while ( have_posts() ) : the_post(); ?> loop

i’ll check if it works
