POWhy is my echo'd PHP variable still producing nothing?
text
Body
copied!<p>I recently was provided an excellent answer on how to handle extracting my URL from HTML content here:</p> <p><a href="https://stackoverflow.com/questions/2173541/extracting-context-from-a-set-point-in-the-middle-of-an-html-file">Extracting context from a set point in the middle of an HTML file</a></p> <p>But after implementing the code, I still show nothing from the echo call on the variable afterwards. I know if I echo get_the_content(), it shows the entire post body as it should, but maybe its not being handled properly by loadHTML()? I implemented the code as provided (which to my knowledge works perfectly aka no errors) and within the foreach loop assigned the extracted URL to a variable so I could use it in the location necessary, as shown by the code below:</p> <pre><code><?php $doc = new DOMDocument(); $doc->strictErrorChecking = FALSE; $xpath = new DOMXpath($doc); $a = 1; if (have_posts()) : while ( have_posts() ) : the_post(); ?> <div class="ORtrack"> <?php $success = $doc->loadHTML(get_the_content()); if ($success === FALSE) { // error handling } else { $hrefs = $xpath->query("//a[contains(@href,'mp3')]/@href"); foreach ($hrefs as $href) { $BEmp3s = $href; } }; ?> <script type="text/javascript"> var myCP<?php echo $a; ?> = new CirclePlayer("#jquery_jplayer_<?php echo $a; ?>", { mp3: "<?php echo $BEmp3s; ?>" }, { cssSelectorAncestor: "#cp_container_<?php echo $a; ?>", volume: 0.5 }); </script> .... <?php endif; wp_reset_query(); ?> </div> </code></pre> <p>There is only ONE MP3 URL to grab per Post body and I always want the first one if for some reason there does end up being multiple MP3 URL's, so is it really necessary to build the array? What am I still missing and is this the most efficient manner to accomplish this?</p>
