On a movie information wordpress theme i am developing, i have an href with text "watch trailer" on each cover of all movies. This brings a modal window, and that is working already, but i want to bring the trailer of the movie onclick, without having to reload the page.

For testing purposes and to ask for help here, i've made a loop that will obtain the data necessary for this "info" href for only one movie.

(head.php has the ajax library in it)


<?php include 'head.php' ?>
function trailerProcess(){
            url:   'sendTrailer.php',
            type:  'json',
            beforeSend: function () {
                    $(".trailerPadding").html("Processing, wait please...");
            success:  function (response) {
<?php $args = array('tag'=> 'newMovies', 'posts_per_page' => 1,); ?>
<?php query_posts( $args ); ?><?php while ( have_posts() ) : the_post(); ?>
<a href="#modal<?php echo get_the_ID(); ?>" onClick="trailerProcess();" class="linkColorWhite">
<div class="botoninfo"><span>watch trailer</span></div>
<div id="modal<?php echo get_the_ID(); ?>" class="modalmask">
<a href="#close" title="Close" class="close">X</a>
<span class="TrailerTitle">Trailer: <?php echo the_title(); ?></span>
<div class="trailerPadding">
<?php // Trailer should be shown here // ?>
<?php endwhile; ?>


<?php require('../../../wp-blog-header.php'); ?>
<?php $values = get_post_custom_values("Trailer"); echo $values[0]; ?>

As outcome, i obtain a 404 error not found sendTrailer.php path on the ctrl+j chrome console. But if in sendTrailer.php i quit the require('../../../wp-blog-header.php'); i get a php "Fatal error: Call to undefined function get_post_custom_values..." displayed, so it finds the file, knowing that wp functions won't work. But if i also quit the require function and write <?php echo "hello" ?>the whole code works and the "hello" gets displayed. So, my conclusion is that the require function is causing this 404 error not found... why? ¿How can i work out this?


EDIT: I have replaced the wp-blog-header.php with load.php, the wordpress data now works and i get no "processing...", but it still doesn't get nor echoes the custom value of $values in sendTrailer.php.

You can't directly use sendTrailer.php ,wordpress can't find this custom page directly so you have to specify fully path of that page using


In your ajax function write

url : '<?php echo get_template_directory(); ?>/sendTrailer.php'
  • Check the edit. Btw, the full url or the php template directory was giving the same result. Dec 22, 2014 at 0:05
