echo out to "early"

Hi there,

you could use a filter like so:

function db_after_single_content($content) {
    if ( is_single() ) {
        $aftercontent = 'this appears after the content';
        $fullcontent  = $content . $aftercontent; 
    } else {
        $fullcontent = $content;
    }
    return $fullcontent;
}
add_filter('the_content', 'db_after_single_content');

or you could use a the generate_after_content hook:

Hi David,

I use for the time being the hook solution. I want to integrate the additional ouput into my custom post but I do not find the template 'content,single' which has to be changed.

In your function I do not understand how to fill the variable $content when I use the standard template.

Hooks are the best route to take, the filter is handy if you need it inside the_content itself.
The $content is whatever is already in the_content e.g from the WP Editor.

Okay - I stay with the hook. Thanks, David.

You're welcome :)
