Importing an RSS feed into post whilst using a custom field?

  • Hi,
    Hope you can help with something. I currently have this code in my posts page:

    <?php if(function_exists('fetch_feed')) {

	include_once(ABSPATH . WPINC . '/feed.php');               // include the required file
        $feed = fetch_feed('RSS FEED ADDRESS HERE'); // specify the source feed

	$limit = $feed->get_item_quantity(7); // specify number of items
	$items = $feed->get_items(0, $limit); // create an array of items
	$feed->set_cache_duration (43200);

}
if ($limit == 0) echo '<div>The feed is either empty or unavailable.</div>';
else foreach ($items as $item) : ?>

<div>
	<b><?php echo $item->get_title(); ?></b>

</div>
<div>
	<?php echo substr($item->get_description(), 0, 200); ?>
</div>
<br>

<?php endforeach; ?>

    This works great – simply enter a valid RSS feed into the place marked ‘RSS FEED ADDRESS HERE’ and it will display on the post.

    What I would like your help with is making the ‘RSS FEED ADDRESS’ pull in the address from a custom field.

    So, say I have two posts, both need to pull in a different RSS Feed.

    I have a custom field named RSS and I’ve entered the RSS feed url in there.

    How can I have it populate the code?

    I can pull in the custom field no problem using`<?php
    global $wp_query;
    $postid = $wp_query->post->ID;
    echo get_post_meta($postid, ‘RSS’, true);
    wp_reset_query();
    ?>`

    I just don’t know how to get it into that code.

    I will then wrap an if statement around the whole thing so that if there is no custom field named RSS it won’t display.

    Any help greatly appreciated.

    Dan

    ok,
    If it helps I have now inserted a function

    function get_custom_field_data($key, $echo = false) {
	global $post;
	$value = get_post_meta($post->ID, $key, true);
	if($echo == false) {
		return $value;
	} else {
		echo $value;
	}
}

    So that all I need do now is have`<?php {
    get_custom_field_data(‘RSS’, true);
    } ?>`

    Inserted into my post template to have the custom field displayed on the page.

    I still can’t get it to work within my fetch_feed function though ??

    Thanks

    ok,
    managed to get this working and here is the code if anyone needs it:

    <?php if(get_post_meta($post->ID, "Address", true)): ?>
<?php {
$my_custom_field = get_post_meta($post->ID, "RSS", true); 

	$feed = fetch_feed(get_post_meta($post->ID, "RSS")); // specify the source feed
	$feed->set_cache_duration (43200);
	$limit = $feed->get_item_quantity(10); // specify number of items
	$items = $feed->get_items(0, $limit); // create an array of items

}
foreach ($items as $item) : ?>

	<p><a href="<?php echo $item->get_permalink(); ?>"
	  title="<?php echo $item->get_date('j F Y @ g:i a'); ?>">
		<?php echo $item->get_title(); ?>
	</a><br />
	<?php echo strip_tags($item->get_description()); ?>
	</p>

<?php endforeach; ?>
<?php endif; ?>

    Basically I have a custom field named RSS – in the custom field I can then place an RSS feed url. If this doesnt exist then nothing is displayed.

    I’ve also stripped tags from my HTML code as one of the feeds I was importing contained code that screwed up my site.
