I was looking for ways to preset html content to the editor upon the creation of new posts. I've found many examples to how to do that for text but i wasn't able to figure out how to do the same thing with html content. (ex: text + images). Here is the example I've found:
add_filter( 'default_content', 'my_editor_content' );
function my_editor_content( $content ) {
$content = "my-preset-content-here";
return $content;
}
Any help in the matter would be appreciated!
