insert post's tags into the function posts_by_tags($tags);
-
I am using a widget of my theme to display a number of post selected by category on the site’s homepage.
I have slightly modified the code to include the functionality of posts_by_tag to display a number of post related to the first article.My issue is I do not know how to combine the function
$posttags = get_the_tags();
with
posts_by_tag($tags);
What I would like to do is to get the tag of the post that is being processed using the get_the_tags function and put it as string variable into the post_by_tag function.
I tried few combinations but it did not work , probably I am missing something minor.
Any help would be appreciated

Can you post the source code of the your theme’s template that you are trying to modify?
