# Display custom-post type based on the Title matching the current selected value

Ok quite a complex thing I'm trying to do here, and I'm a bit unsure how I will do it with wordpress, but I'm hoping some genius out there can help.

I'm basically creating some comparison functionality, and I currently have two select boxes on the page. These select boxes will display the list of all posts within the custom post-type 'countries' inside them, and when the user selects one of the options from the list, I will use ajax to display the content of that particular post below.

I currently have a non-wordpress version of what I am trying to do, and here's the code.

HTML

<select id="compare-one">
<option value="United Kingdom">United Kingdom</option>
<option value="Belarus">Belarus</option>
<option value="Albania">Albania</option>


Jquery

$('#compare-one').change(function(e){$('#compare-one-container').empty();
$(this).find(':selected').each(function(i,e){$.get("callbacks.php",
// used to prevent caching in IE
{ nbRandom: Math.random() },
function(data){
$("#compare-one-container").html(data); }); });  }); callbacks.php <?php$test = "Home" ?>


So as you can see, I have no implemented this into Wordpress just yet - simply because I'm unsure of the right way to do so!

I think my main question is how to replace this current php code with something that checks to see if the current selected value is equal to the page title, and if so echo the information (content, custom fields etc) from that particular page title it matches.

Any help on this would be greatly appreciated!

Thanks

Don't really get what your main issue.. are you try to comparing two post types and display it in a page template? or are you try to comparing the current page with the selected post types?

try this create a page template

<?php
/*
* Template Name: Compare
*/
?>

<?php
?>

<form id="customsearch" action="" method="post">
<select name="compare-one" id="compare-one">
<option value="130">1</option>
<option value="102">2</option>
</select>

<select name="compare-two" id="compare-two">
<option value="130">1</option>
<option value="102">2</option>
</select>

</form>
<script type="text/javascript">
$(document).ready(function() {$('#compare-one').change(function() {
var compareone_value = $('#compare-one').val(); var data = { 'action':'callback_function', 'compare-one':compareone_value, };$.post(ajax_object.ajaxurl, data, function(response) {
$('#compare-one-container').html(response); }); });$('#compare-two').change(function() {
var comparetwo_value = $('#compare-two').val(); var data = { 'action':'callback_function', 'compare-two':comparetwo_value, };$.post(ajax_object.ajaxurl, data, function(response) {
$('#compare-two-container').html(response); }); }); }); </script> <div id="compare-container"> <div id="compare-one-container"> </div> <div id="compare-two-container"> </div> </div> <?php get_footer(); ?>  next add a callback function to your functions.php add_action('wp_ajax_callback_function', 'callback_function'); add_action('wp_ajax_nopriv_callback_function', 'callback_function'); // for not logged in user function callback_function() { if (isset($_POST['compare-one']) || isset($_POST['compare-two'])) {$arr_id = array($_POST['compare-one'],$_POST['compare-two']);
$temp =$wp_query;
$wp_query = null;$wp_query = new WP_Query();

$wp_query->query(array('post_type' => 'listing', 'posts_per_page' => 2, 'post__in' =>$arr_id));
while ($wp_query->have_posts()) :$wp_query->the_post();
$custom = get_post_custom($post->ID);
$beds =$custom['_beds'][0];
$baths =$custom['_baths'][0];
apply_filters('the_title', the_title());
apply_filters('the_content', the_content());
endwhile;
$wp_query = null;$wp_query = $temp; rewind_posts(); } die(); } ?>  and don't forget to localize WordPress ajax script to use in front page wp_enqueue_script( 'ajax-script', 'ajax_object', array('jquery')); wp_localize_script( 'ajax-script', 'ajax_object', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) ); // setting  - for the select option I use my own post type and post id so it's 130 and 105 :D and the post type is listing – nackle Dec 18 '11 at 16:17 perfect! All I added was some code to the select boxes so that I dynamically grab all posts and their ids: <?php$city = new WP_Query(array('post_type' => 'city', 'orderby' => 'name', 'order' => 'ASC', 'posts_per_page' => -1 )); ?> <?php while ($city->have_posts() ) :$city->the_post(); ?> <option value="<?php the_ID(); ?>"><?php the_title(); ?></option> <?php endwhile; ?> –  remi90 Dec 19 '11 at 10:47
Nice to see it work well.. please vote for the answer if it's really helpful –  nackle Dec 19 '11 at 13:57
regarding your code, I've adjusted it slightly, but for some reason I just cannot seem to echo the value of a custom-field I created using Magic fields: Between the 'while' statement I included: $timezoneshow = get('timezone'); echo$timezoneshow; But for some reason it breaks the whole thing. I also wondered whether it's better to move the display parts to the actual template file (ie. echo the title and content in the template file rather than the functions.php). I'm not an expert with PHP so some advise would be great –  remi90 Dec 19 '11 at 14:10
is the timezone your custom field related to the post or it's another function? –  nackle Dec 19 '11 at 18:04
