# functions.php with child theme?

 * This plugin is not working for me. I have set up a child theme and my main theme
   is a social media type theme where users can post images and repost them, etc.
   I am trying to get the hashtags to work so that when they post an image they 
   can add a #hasshtag or a @mention int he comments. I think, that I need to use
   this part:
    // this function can be used in theme // does all the hashtagger 
   stuff on a string function do_hashtagger( $content ) { return swcc_htg_content(
   $content ); } **I am fairly new to configuring these things. I need help figuring
   out where to include the function. When I go to the plugins folder of the parent
   theme, and look at Hashtagger.php I can see this line of code, however, when 
   I create hashtags, nothing is happening. Thank you in advance.

 * OK, first of all please note that it is **not** possible to generate tags from
   hashtags used in comments and add them to the post which the comment belongs 
   to. This is because hashtagger adds the tags to the actual object and it is not
   possible to add tags to comments. So it would be necessary to first search the
   post where the comment belongs to and add the tags to this. This functionality
   is not provided by hashtagger yet. Maybe in a future version, but I’m not sure
   if it makes sense a visitor can add tags to a post by commenting it…
 * The do_hashtagger() function only adds the links to **existing** tags. If the
   tag is nout found the #hashtag stays untouched without a link generated. If this
   is enough for you it can be used. Otherwise I’m sorry, this can’t be solved using
   hashtagger.
 * Add this code to your functions.php to get it work:
 *     ```
       function my_hashtag_it( $content ) {
         return do_hashtagger( $content );
       }
   
       add_filter( 'comment_text', 'my_hashtag_it', 99 );
       ```

 * Thank you Peter! Sorry for the late reply. Hashtagger is working wonderfully 
   for me. I should have been more specific about why I wanted to use the function
   in the comments section. I actually wanted people to be able to use the [@username](https://wordpress.org/support/users/username/)
   function, but not the #Hashtag function. I am not sure if this is available yet,
   or going to be, but I am more interested in using [@username](https://wordpress.org/support/users/username/)
   in comments and being able to click it. The reason for this is so that my users
   can comment on a post and mention another user in their comment. Ex: [@username](https://wordpress.org/support/users/username/)
   You would really like this! This does bring up another topic though, and that
   is being able to integrate the @mentions into my notification system. I would
   also need a way to tell [@user](https://wordpress.org/support/users/user/) that
   someone has mentioned their name in a post/comment. Thank you again for the plugin
   and the help.

 * Hi Brady,
 * the code I postet should make [@usernames](https://wordpress.org/support/users/usernames/)
   in comments clickable (but also hashtags). But if you want to use it on your 
   frontend than also on typing a check if the name exists would be recommendable.
   Like e.g. on facebook. And the mail notification is a second thing…
 * That’s more a social network functionality than a blogging functionality. As 
   yet I think this will never be possible with hashtagger because your requirements
   are too specific and the development effort would be to huge for a free plugin.
 * … but who knows?
 * Regards
    Peter
