I'm at a loss, I've found several unanswered questions related to this one. I have a static post page which has a search form in the sidebar. What I want to happen is to type in a keyword and then 'filter'(return with ajax) only the posts that fit the search. I also want it to be paginated.
I've found several ways to manipulate $wp_query so that I can use the same loop for the ajax call. Unfortunately when I look global $wp_query in functions.php where my callback action is, it is basically null or initialized to default parameters. I debugging everything locally, I wonder if that would affect anything. I haven't confirmed it but shouldn't that global variable stay the same unless something explicitly happens to it(like navigating to a new page)?
This is the callback in functions.php
function cbSearch()
{
$counter=1;
$html="";
global $wp_query;
if ( have_posts() )
{
while ( have_posts() )
{
the_post();
$html.="<div class='news-page-item'>";
$html.=the_title('<h2>','</h2>');
$date= strtoupper(get_the_date('F Y'));
$subtitle = get_post_meta (get_the_ID(), 'subtitle', $single = true);
$summary = get_the_excerpt();//get_post_meta (get_the_ID(), 'summary', $single = true);
$html.="<div class='fg-grey f12 mt8'>".$subtitle." - ".$date."</div>";
$upload_dir = wp_upload_dir();
$html.="<img class='mv25' src='".$upload_dir['baseurl']."/news-item.jpg' alt='".get_the_title()."' />";
$html.="<p class='f15'>";
$html.=$summary;
$html.="<a href='".get_permalink()."' class='fg-grey f11'> › READ MORE</a>";
$html.="</p>";
if ($counter != count($posts))
{
$html.="<hr class='mv30 c888' />";
}
++$counter;
$html.="</div>";
echo $html;
$html="";
}
}
$html.="<div id='news-page-nav'>";
$html.="<span class='left'>";
$html.=get_previous_posts_link(" P ");
$html.="</span>";
$html.="<span class='right'>";
$html.=get_next_posts_link(" N ");
$html.="</span></div>";
echo $html;
die();
}
I use a breakpoint in this function to find the $wp_query parameters.
This is what is returned when I do a var_dump immediately after calling global $wp_query;

I know that ajax function is working. Can anyone tell me why $wp_query turns into garbage somewhere between page load and the http request?
