Unlike the tag could widget which creates links based on a single tag, I'm trying to return entries based on all/each tags of a post.

If I use a function like this, I only get entries that match the entire tag string.

function GetTags(){
	return DataObject::get('BlogEntry',"Tags = '$this->Tags'",'','','');
}

What I want to return is all entries that share each of {$this->Tags}.

So if my entry is tagged (Chicken, BBQ, Summer) I want to return not just entries tagged 'Chicken, BBQ, Summer', but all entries tagged with Chicken and/or BBQ and/or Summer.

I assume my syntax Tags = {$this->Tags} is the issue. I probably need to bust apart $this->Tags into individual tags and return those, but I do not know the SQL syntax to say 'where one tag is x and one tag is y and one tag is z...'

Any guidance is greatly appreciated.

Thanks

This is as close as I can get. I'm using $relatedLink = "Tags ='000'"; to start off the SQL since my foreach() is returning "OR Tags LIKE..."

"000" should return nothing. I can't believe that's a great way to do this, but I can live with it.

The only thing I can't figure out is how to remove the current entry page from the results.

class ExtendedEntry_Controller extends BlogEntry_Controller {
    function GetAllRelTags(){
	$theseTags = "$this->Tags";
	$eachTag = explode(',',$theseTags);
	$relatedLink = "Tags ='000'";
	foreach($eachTag as $relatedTag) {
		$relatedLink.= " OR Tags LIKE '%".$relatedTag."%' ";
	}
	return DataObject::get('BlogEntry',$relatedLink,'','','');
    }
}
