[Plugin: Google XML Sitemaps] Early testers wanted

@arnee: I have created another sitemap for sub-blog account (WP3 Multisite) and google webmaster tools downloaded it successfuly (http://tzmatulji.hr/iznajmljivaci/sitemap.xml).

But there is still no luck with main site sitemap, although I don’t see any obvious problem.

No arnee it didn’t work. I deleted older version of your plugin from server, uploaded new one and activated it, added new post to generate new sitemap and submitted it manually go WMT.
Is there anything else I should do? Plugin kept settings from old version even after it was deleted and reinstalled.

@arnee
I deactivated and deleted old version, than activated new. I tried to deatcivate & activate plugin few times, also changed link structure to default and back and problem was same.

Temporarily solution was those two lines. I’ll try ver 4.0a3 later.

Got it going on a couple of sites. Google is reading most of the sub-sitemap links from the main sitemap page but I’m getting a blank page with others. When I view the source i get this

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="http://www.myefficientenergy.com/wp-content/plugins/google-sitemap-generator/sitemap.xsl"?><!-- generator="wordpress/2.9.2" -->

I appreciate the plugin. Thanks for all the hard work. Here are some more fixes I had to make. First, just to make the custom post type sitemap url work (http://shouldipourit.com/sitemap-beers-2010-08.xml) I had to edit sitemap-builder.php. In the switch statment in the Content() funtion I moved the posts and pages cases to the bottom and made that the default:

case "posts":
case "pages":
default:
	$this->BuildPosts($gsg, $type, $params);

To make the index work (http://shouldipourit.com/sitemap.xml) I first added the processing for custom post types after the processing for posts and pages, but the code was basically all duplicate, so I remove the whole if (in_posts || in_pages) part of the Index() function in sitemap-builder.php and replaced it with this:

$posttypes = $gsg->GetOption('in_customtypes');
if ( !is_array($posttypes) ) {
	$posttypes = array();
}
if($gsg->GetOption("in_pages")){
	array_unshift($posttypes, 'page');
}
if($gsg->GetOption("in_posts")){
	array_unshift($posttypes, 'post');
}

//Add filter to remove password protected posts
add_filter('posts_search',array($this,'FilterPassword'),10,2);

//Add filter to remove fields
add_filter('posts_fields',array($this,'FilterIndexFields'),10,2);

//Add filter to group
add_filter('posts_groupby',array($this,'FilterIndexGroup'),10,2);

foreach($posttypes as $posttype) {
	$qp = $this->BuildPostQuery($gsg,$posttype);

	$qp['cache_results']=false;

	$posts = @get_posts($qp);
	if ($posts) {
		foreach ($posts as $arcresult) {
			$gsg->AddSitemap($posttype.'s',sprintf("%04d-%02d",$arcresult->year,$arcresult->month), $gsg->GetTimestampFromMySql($arcresult->last_mod));
		}
	}
}
//Remove the filters again
remove_filter('posts_where',array($this,'FilterPassword'),10,2);
remove_filter('posts_fields',array($this,'FilterIndexFields'),10,2);
remove_filter('posts_groupby',array($this,'FilterIndexGroup'),10,2);

Everything seems to work as expected now.

Hi Arne – I’ve put this on a test site, and you can see the sitemaps here:
http://www.investingguide.com.au/sitemap.xml
http://www.investingguide.com.au/directory/sitemap.xml

They look to be working correctly. I have a couple of questions though:
1 – Do you know if there is any issue with Google if my site has two sitemaps? If so, have I set something up wrong? Or should I manually add the /directory home page url in the ‘additional pages’ section of the main site’s sitemap settings?
2 – I noticed that it no longer lists all links on one page, but links to sub-pages with the sitemap (eg. http://www.investingguide.com.au/sitemap-pages-2010-08.xml). Is that correct or have I also set this up wrong?

Thank you so much for this plugin. I hope we’re not causing you too many headaches!?!?

Cheers, Rob
