huh. I am really missing something. I’m sorry, I’m not a very good programmer at all. It’s really frustrating because conceptually i get how it should work, but then I can’t make it happen.

I put the above code in playlist.php file with a call to the wp-blog-header. I started the loop and am accessing the file like this: playlist.php?p=8

Nothing happens. I looked at the rss2 file… here is where i think the problem is:

I’m not specifically putting this file in a custom field as an eclosure. I’m relying on wordpress to autodetect the LINK in the post and then do all of it’s magic. so I am not manually storing this as an eclosure. I’m trying to make it as simple as possible, and I’m using the upload -> send to editor fuction to put my podcast in the post.

Does that make sense? am I approaching this completely wrong.

Ok. I’m having some trouble getting this to work. I’ve made a standalone .php file with the following:


<?php
/* Short and sweet */
define('WP_USE_THEMES', false);
require('./wp-blog-header.php');

$custom_fields = get_post_custom();
if( is_array( $custom_fields ) ) {
while( list( $key, $val ) = each( $custom_fields ) ) {

if( $key == 'enclosure' ) {
if (is_array($val)) {

foreach($val as $enc) {
$enclosure = split( "n", $enc );

// your output here instead of the following

echo "hello";
echo "url=".trim( htmlspecialchars($enclosure[ 0 ]) );
echo "length=".trim( $enclosure[ 1 ] );
echo "type=".trim( $enclosure[ 2 ] );

}
}
}
}
}

?>

I’m not getting anything returned on the page. Do I need to run this inside the loop? Should I actively try and query a post when I access it (playlist.php?p=8)?

I’m trying to build the address of the enclosure into a xspf type playlist. Thanks!

heh. come on you guys! I believe in you. 😉

Ok, I figured it out!

On this page: http://codex.wordpress.org/The_Loop
Scroll down, you’ll see this:

<?php $my_query = new WP_Query(‘category_name=special_cat&showposts=10’); ?>

<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<!– Do special_cat stuff… –>
<?php endwhile; ?>

<?php rewind_posts(); ?>

What you want to do is build your own query, then reweind posts to reset the query object so that list_pages doesn’t break.

Hrm… not sure I’m explaining this the right way.

the default output for the <?php wp_list_pages(‘title_li=’); ?> tag is this for every link: (sorry, i’m using brackets for the a link)

<li class=”page_item”>[a href=”http://www.mysite.com?page_id=4&#8243; title=”About Page”]About[/a]

If I have 5 pages, they all end up with that exact same markup. Now if I’m page 4, the about page, for example, and I want that single page to have a different background in the navigation… I’m going to need to add an ‘onstate’ class to the releveant a link.

So wordpress will have to know that I am currently on page 4, and that since i’m on page 4, it needs to style the link to page 4 in the navigation differently by adding a class to the a tag.

I have been looking for plugins to do this, but i don’t see any. It’s pretty standard user interface stuff to want to have your navigation display like this. I’ve been poking around and trying to re-format the ‘template_functions_post’ file which contains the actual function i’m looking at:

function wp_list_pages($args = ”) {
parse_str($args, $r);
if ( !isset($r[‘depth’]) )
$r[‘depth’] = 0;
if ( !isset($r[‘show_date’]) )
$r[‘show_date’] = ”;
if ( !isset($r[‘child_of’]) )
$r[‘child_of’] = 0;
if ( !isset($r[‘title_li’]) )
$r[‘title_li’] = __(‘Pages’);
if ( !isset($r[‘echo’]) )
$r[‘echo’] = 1;

$output = ”;

// Query pages.
$pages = & get_pages($args);
if ( $pages ) {

if ( $r[‘title_li’] )
$output .= ‘<li class=”pagenav”>’ . $r[‘title_li’] . ‘

‘;

// Now loop over all pages that were selected
$page_tree = Array();
foreach ( $pages as $page ) {
// set the title for the current page
$page_tree[$page->ID][‘title’] = $page->post_title;
$page_tree[$page->ID][‘name’] = $page->post_name;

// set the selected date for the current page
// depending on the query arguments this is either
// the createtion date or the modification date
// as a unix timestamp. It will also always be in the
// ts field.
if ( !empty($r[‘show_date’]) ) {
if ( ‘modified’ == $r[‘show_date’] )
$page_tree[$page->ID][‘ts’] = $page->post_modified;
else
$page_tree[$page->ID][‘ts’] = $page->post_date;
}

// The tricky bit!!
// Using the parent ID of the current page as the
// array index we set the curent page as a child of that page.
// We can now start looping over the $page_tree array
// with any ID which will output the page links from that ID downwards.
if ( $page->post_parent != $page->ID)
$page_tree[$page->post_parent][‘children’][] = $page->ID;
}
// Output of the pages starting with child_of as the root ID.
// child_of defaults to 0 if not supplied in the query.
$output .= _page_level_out($r[‘child_of’],$page_tree, $r, 0, false);
if ( $r[‘title_li’] )
$output .= ‘
‘;
}

$output = apply_filters(‘wp_list_pages’, $output);

if ( $r[‘echo’] )
echo $output;
else
return $output;
}

so somewhere in there I should be able to tell it, ‘if this is the current page’ then ‘output this class in the link’.

Thanks for your help people!
