Broken Link Checker for WordPress

Sometimes, links get broken. A page is deleted, a subdirectory forgotten, a site moved to a different domain. Most likely many of your blog posts contain links. It is almost inevitable that over time some of them will lead to a “404 Not Found” error page. Obviously you don’t want your readers to be annoyed by clicking a link that leads nowhere. You can check the links yourself but that might be quite a task if you have a lot of posts. You could use your webserver’s stats but that only works for local links.

So I’ve made a plugin for WordPress that will check your posts (and pages), looking for broken links, and let you know if any are found.

Download it now! (423 KB)

Features

  • Detects links that don’t work and missing images.
  • Periodically checks links in posts, pages, comments and the blogroll.
  • New and modified entries are checked ASAP.
  • Notifies you on the Dashboard if any problems are found.
  • Lets you edit all instances of a specific link at once.
  • Gives you a list of all links ever posted on your site, with the ability to search and filter it.
  • Lets you apply custom CSS styles to broken and removed links.
  • Highly configurable.

The broken links show up in the Tools -> Broken Links tab along. If any invalid URLs are found a notification will also show up on the Dashboard widget. To save screen real-estate, the widget can be configured to stay closed most of the time and automatically expand when broken links are detected.

Installation

Install “Broken Link Checker” just like any other WordPress plugin :

  1. Download the .zip file.
  2. Unzip.
  3. Upload the broken-link-checker folder to you /wp-content/plugins directory.
  4. Activate the plugin in the Plugins tab.

Requirements

  • WordPress 3.0 or later
  • MySQL 4.1 or later

The current version of this plugin is only compatible with WordPress 3.0 and up. If you have an older version of WP, try one of the older releases. Specifically, version 0.8.1 is the last one that’s still compatible with the WP 2.8 branch, and version 0.4.14 is the last one compatible with WP 2.1 – 2.6.x.

    I’m having this problem when using broken link checker and Simplepress Forum,

    “Fatal error: Cannot redeclare json_encode() (previously declared in wordpress/wp-content/plugins/simple-forum/library/JSON.php:810) in /wordpress/wp-content/plugins/broken-link-checker/utility-class.php on line 16″

    It seems you must wrap the JSON calls with if(!function_exists()) calls. There should be no conflict.

    best regards

    It is wrapped with if(!function_exists()) calls, so I must say I’m quite confused by this error. See the relevant code fragment :

    if (!function_exists('json_encode')){
	//Load JSON functions for PHP < 5.2
	if (!class_exists('Services_JSON')){
		require 'JSON.php';
	}
 
	//Backwards compatible json_encode.
	function json_encode($data) {
	    $json = new Services_JSON();
	    return( $json->encode($data) );
	}
}

    In that case, there is no clue, from where the error is coming from?

    Hey Janis –

    Don’t know what you do on this last iteration of the plugin but it seems to work a LOT better now. The broken links really are broken! :) Thank you for your continued development!

    @mgomes : I installed the latest version of the SimplePress forum to see what causes the problem, and I’m not getting the error you mentioned. Both plugins appear to co-exist peacefully.

    Do you have the latest versions of both the broken link checker and the forum plugin?

    @Dan : Ahha, thanks :)

    dude, this is an awesome plugin and pretty quick one if one know how to work with wordpress plugin. However, this plugin have quite a serious issue on the amount of resource it takes on the server which is not that good. Please look this up. Thanks :)

    The error only happens when you post a topic to simplepress forum. that’s the only time.

    I’m using SPF 4.1 beta.

    @ mgomes : Try installing the development version. I added a little workaround that may help.

    @ Clay : I’d be glad to reduce the resource usage, but I don’t see any easy ways to do that. If you have any practical ideas on how to improve the plugin’s performance, don’t hesitate to reveal them ;)

    Just installed the upgrade and if I try to run this along with WP Super Cache it makes my blog unusuable…can’t access home page or admin area. Have to disable BLC and WPSC by renaming folders in Cpanel (to disable both plugins) then I can enable one or the other, but not both. Enjoyed it while it lasted, but until this is fixed, I value WP Super Cache much more.

    …this is bad, and I have no idea why it would happen. I’ll try to find out.

    Meanwhile, you could use one of the older versions of the plugin. The DB format should be backwards-compatible for all 0.5.x releases.

    Patti, you could also try this modified version. I doubt it will help much, but it’s worth a try.

    Thanks White Shadow. I’ll go back to the older version for now. Loved the plugin and never had a problem with it (other than the occasional false report of a dead link) before the latest upgrade. I have another blog that does fine with the latest version (http://shop.bostonsandboxers.com/store) but I don’t run wp-super cache on that install.
    Thanks again for your help, and courtesy. I hesitated even reporting the issue as my previous experience w/plugin authors was less than pleasant. It’s nice to be treated with common courtesy :)

    Sorry to be dense … I loaded the link checker and have assumed all was well until I found a broken link in my site … went back and the BLC said nothing about it. Upon further inspection I read the script’s output more carefully in the admin site, realizing that it isn’t telling me I have zero broken links … it says I have zero links!

    Specifically it says:
    No broken links found.
    No URLs in the work queue.
    No links detected.

    I searched the site for others who have experienced this phenomenon for some insight and direction, but couldn’t make any progress. Can you give me any advice on how to proceed in troubleshooting or checking the configuration more intensely?

    Thanks in advance!

    That is most certainly a bug. Try this version of the plugin and run a re-check from the options page (and please report back if it works).

    I tried installing the older version of the plugin and got the same result (where it ran w/o a problem before). In order to access my bog’s dashboaed or homeage I had to rename BOTH plugin folders (BLC and WP-supercache) in order to deactivate the plugins and regain access. I don’t get it, but I can’t afford to keep crashing my blog. Thanks for trying :)
