How to extract links to mp3s from an entry to make a playlist?

  • Problem
    I run a music-blog and my authors copy links to the creative commons music mp3s directly in the post. Now, I want to extract these links to generate a special m3u-playlist. Therefore I made a new page and a new page template. Unfortunately I am no php-expert and after 4 hours I am quite frutstrated. I have a php-script which extracts the links, but now, I don’t know how to show them.

    Script

    <?php /* Template Name: Netaudio Player Page */ ?>

<?php query_posts('cat=106&showposts=1'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php
$content = get_the_content('');

function pc_link_extractor($s) {
  $a = array();
  if (preg_match_all('/<a\s+.*?href=[\"\']?([^\"\' >]*)[\"\']?[^>]*>(.*?)<\/a>/i',
                     $s,$matches,PREG_SET_ORDER)) {
    foreach($matches as $match) {
      array_push($a,array($match[1],$match[2]));
    }
  }
  return $a;
}

$a = pc_link_extractor($content);
print_r($a);

endwhile; endif; ?>

    this gives me a wonderful list, with quite good results. but what now?

    I solved it with some luck. The following code extracts from category with id 106 the links to the mp3s from the last 5 entries. now it’s very easy to build huge download-lists or m3u-lists. hopefully someone can use this.

    <?php /* Template Name: MP3 Links Page */ ?>
<?php

function pc_link_extractor($s) {
  $a = array();
  if (preg_match_all('/<a\s+.*?href=[\"\']?([^\"\' >]*).mp3[\"\']?[^>]*>(.*?)<\/a>/i',
                     $s,$matches,PREG_SET_ORDER)) {
    foreach($matches as $match) {
      echo '<a href="' . $match[1] . '.mp3">' . $match[2] . '</a><br />' . "\n"  ;
    }
  }
  return $a;
}

// mp3 category = 106
query_posts('cat=106&showposts=5');
if (have_posts()) : while (have_posts()) : the_post();

$content = get_the_content();
$a = pc_link_extractor($content);

endwhile; endif;

?>
