Adding other pages to the sitemap via other plugins
This plugin uses the action system of WordPress to allow other plugins
to add urls to the sitemap. Simply add your function with add_action to
the list and the plugin will execute yours every time the sitemap is build.
Use the static method "GetInstance" to get the generator and AddUrl method
to add your content.
Sample:
function your_pages() {
$generatorObject = &GoogleSitemapGenerator::GetInstance(); //Please note the "&" sign!
if($generatorObject!=null) $generatorObject->AddUrl(”http://blog.uri/tags/hello/”,time(),”daily”,0.5);
}
add_action(”sm_buildmap”,”your_pages”);
Parameters:
– The URL to the page
– The last modified data, as a UNIX timestamp (optional)
– The Change Frequency (daily, hourly, weekly and so on) (optional)
– The priority 0.0 to 1.0 (optional)
===============================================
Adding additional PriorityProviders
This plugin uses several classes to calculate the post priority.
You can register your own provider and choose it at the options screen.
Your class has to extend the GoogleSitemapGeneratorPrioProviderBase class
which has a default constructor and a method called GetPostPriority
which you can override.
Look at the GoogleSitemapGeneratorPrioByPopularityContestProvider class
for an example.
To register your provider to the sitemap generator, use the following filter:
add_filter(”sm_add_prio_provider”,”AddMyProvider”);
Your function could look like this:
function AddMyProvider($providers) {
array_push($providers,”MyProviderClass”);
return $providers;
}
Note that you have to return the modified list!
