   Hey Gilles, take a look at the plugin FAQ where I’ve included some sample code for grabbing the enclosures from a feed. It should be enough to get you started.

   I followed your instructions. However, when trying to activate I get the follow error:

   Fatal error: Cannot redeclare fetch_rss() (previously declared in /path/to/server/htdocs/wp-includes/rss.php:390) in /path/to/server/htdocs/wp-content/plugins/magpierss-hotfix.php on line 525

   I don’t understand how you are trying to override fetch_rss()

   Apart from copying your code into the rss.php file, do you have a nicer /plugin way?

   Thanks for the plugin /your help.

   Hank, that’s odd.

   The function fetch_rss() is a pluggable function. This means that a plugin can override it simply by declaring it. If you take a look at wp-includes/rss.php you’ll note that fetch_rss() is wrapped in a check:

   if ( !is_function('fetch_rss') ){ …function here… }

   I have an idea why this error is ocurring though. I’ll push an updated version of the plugin out shortly.

   John.

   Version 1.0.1 released – Wrap the patched fetch_rss() function in a function_exists() check to prevent errors upon activation.

   John, thanks for the update. No error messages when updating now indeed. However, I can’t retrieve the enclosure url following your instructions. Any idea what’s causing this?

   Just interested: which plugins are you using for previewing comments /subscription management?

8. November 12th, 2008 at 10:48 am John Blackbourn Says:

   Hank, which version of WordPress are you using?

   Comment preview plugin is here and comment subsription plugin is here :)

   John, thanks for the links! I am using WordPresss version 2.6.3

    Hank, can you send me the code you’re using to get the enclosure links? Feel free to email me at the email address shown here.

    Version 1.1 released – The plugin now clears WordPress’ RSS cache upon activation so fresh feeds are fetched and then cached complete with their enclosures.

    John, you have saved my sanity with this ingenious little plugin!

    Many thanks.

    WARNING: This “hotfix” is a nightmare to deactivate. Since it didn’t fix my problem (I still got those weird symbols), I tried to rid my WP installation of the plugin, only to have it return the error Hank mentions above. Your code really needs to be changed so it doesn’t create hassles for users who decide they don’t want the plugin after trying it out.

    How do I get the plugin completely out of my installation without having to install WP all over again from scratch? Please provide the solution here so future users can find it easily.

    Hi Lisa, thanks for the comment.

    Sorry the plugin didn’t fix your character encoding issue. Do you have a link to your blog?

    If you can’t deactivate the plugin from the Plugins menu in WordPress, simply delete the plugin files from your server and the plugin will be automatically deactivated.

    Please let me know if your blog still shows any errors after deleting the plugin.

    Plugin version 1.2 released. Fixes possible errors on activation.

    I am using KB Advanced RSS plugin that uses MagpieRSS. Looking for solution for enclosures and tried your plugin but it makes KB Advanced RSS die (no error messages). Can’t figure out why because it breaks even on feeds that have no enclosures.

    Unfortunately author of that one is not providing support at moment. :(

    Any hints what else I can try to get enclosures support?

17. January 2nd, 2009 at 5:03 pm Rarst Says:

    PS I tried patching rss.php with your fix for enclosure and it works (also got rid of extra array level). So KB Advanced RSS is probably getting broken by something else in your plugin.

    Big thanks. :) Now I have to figure out how to apply fix without messing with rss.php

    Hi,

    I was searching the internet on how am I going to solve this problem of mine. I was trying to activate a plugin called backlink energizer, this is a plugin that indexes your backlinks faster. I was prompted with the following error when trying to activate it.

    Fatal error: Cannot redeclare fetch_rss() (previously declared in /home/panyang/public_html/waysforkidstomakemoneyonline.com/wp-includes/rss.php:404) in /home/panyang/public_html/waysforkidstomakemoneyonline.com/wp-content/plugins/energizer/lib/rss_fetch.inc on line 221

    I did try installing your plugin hoping to fix this. But I still get the same error.

    You’ll need to contact the author of that plugin to get it fixed. Sounds like the plugin hasn’t been updated to support recent versions of WordPress.
