I try to add some content on the post excerpt in wordpress. For a category page excerpt condition working perfect. but i am not sure how to check in home page i tried is\_home and is\_front\_page like that 

```
    function addtoexcerpt($excerpt) {
    ob_start();

    $values = ob_get_clean();
    return $values.$excerpt;

    }
if(is_single()||is_category()||is_front_page()) {
    add_filter('the_excerpt','addtoexcerpt');
}

```

But for homepage itself is not come's up, i a homepage there is 3more columns with these one of the column as blog post how to check the homepage blogpost in order to append the content 

I am using expound theme template. 

Thanks 
vicky
