# Extension plugins for the plugin (using hooks)

 *  Plugin Author [AntoineH](https://wordpress.org/support/users/antoineh/)

 * [10 years ago](https://wordpress.org/support/topic/extension-plugins-for-the-plugin-using-hooks/)
 * During the last couple of years I have helped several users with all kind of 
   requests to alter the working of the plugin. When I change the plugin’s behavior
   I try use hooks as much as possible. Because when you use hooks, then an upgrade
   of the plugin won’t overwrite your code changes.
 * The help page in the plugin contains some examples and also links to some resources
   on the internet that can help you make your own additions to the plugin.
 * But because I also made some myself, I decided to write this post to share them
   with you.
 * One important note: some of these extensions are very old, so it is possible 
   that some won’t work anymore in the plugin. Maybe the hook is gone or the functionality
   made it to the core of the plugin, making the extension useless. But the file
   may still be valuable as an example for you.
 * **Example**
    If you want to use the hooks in the plugin you have to place your
   code somewhere so WordPress can pick it up. One place you can put your code is
   the functions.php of your theme, but I personally prefer writing a simple plugin
   that you can simply activate/deactivate. I created a template file that you can
   use to create your own plugin. [football-pool-extension-template.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-extension-template.php)
 * **Add match result to User page**
    As the name says: it adds the match result
   to the page where you can see the predictions for a user. [football-pool-add-match-result-to-user-page.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-add-match-result-to-user-page.php)
 * **Change what the ranking looks like**
    This is a simple example on how you can
   change what you want to show in the ranking. This extension always shows the 
   league image in the ranking. If you want to change the looks for the view for
   all users, you will have to check the variable `$all_user_view`. The `$type` 
   variable that is passed to the function tells you if the ranking is displayed
   in the page, the shortcode or the widget. [football-pool-change-ranking-template.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-change-ranking-template.php)
 * **Login names in ranking**
    This extension shows the login name of users in the
   ranking instead of the display name. [football-pool-login-names-in-ranking.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-login-names-in-ranking.php)
 * **Change the display of user names everywhere in the plugin**
    The plugin normally
   shows the display name for a user in the plugin (e.g. the ranking, the shoutbox,
   etc.). But it is very easy to change this to another field in the User object
   or if you would like to add extra HTML code. [football-pool-username-extension.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-username-extension.php)
 * **Change the score calculation (v2.5 and up)**
    Since version 2.5 changing the
   way the plugin calculates the score has become very simple. This example also
   rewards the goal diff points when the match ended in a draw and the user predicted
   a draw. [football-pool-extension-change-calc-score.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-extension-change-calc-score.php)
 * **Change the prediction form HTML**
    Just two simple examples on how you can 
   change the prediction form. The first one adds a save button to the top of the
   form. The second one changes every row in the form and adds a save button in 
   the row. [football-pool-extra-match-save-button-at-top.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-extra-match-save-button-at-top.php)
   [football-pool-extra-match-save-buttons.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-extra-match-save-buttons.php)
 * **Order match predictions**
    Order match predictions by score and don’t show 
   users without predictions. [football-pool-matchpredictions-order.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-matchpredictions-order.php)
 * **Only show ‘open’ matches on the form**
    If you want to hide matches that can’t
   be changed anymore in the form, you can use this extension. It simply filters
   out the matches in the form that are no longer editable for a user and returns
   this set to the function that creates the form. [football-pool-only-open-matches.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-only-open-matches.php)
 * **Pagination**
    Also in the help page of the plugin. A simple function that adds
   pagination to the ranking, matches and prediction page of the plugin. Useful 
   if you have a lot of data and don’t want to show everything on one page. [football-pool-pagination.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-pagination.php)

 * **Prediction upload**
    This extension adds a new menu item in the Football Pool
   admin. The new admin screen enables you to upload predictions for matches for
   a user. The data format of the prediction file is csv and every line should contain
   the match ID, score of home team and score of away team. First line of the csv
   contains the header and is ignored. No jokers can be imported, but this would
   be a small change to also enable that. [football-pool-user-prediction-import-v2.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-user-prediction-import-v2.php)

 * **Golden Games (v2.5 and up)**
    This extension disables the Joker functionality
   for users and allows the admin to select 1 or more games as ‘golden game’. A 
   golden game will award extra points as the scored points will be multiplied by
   the joker multiplier value in the settings. A new admin screen is added to the
   Football Pool admin to set the golden games. Matches that are labeled as golden
   game can be styled in the frontend with the CSS class `fp-golden-game`. [football-pool-golden-games.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-golden-games.php)

 * Hi Antoine,
 * thanks for sharing all your work, the plugin in unbelievably well though and 
   developed, thanks for sharing.
 * I would like to request you to create a plugin to include the flags on the group
   widget (similar to what was suggested in another topic [https://wordpress.org/support/topic/team-flagslogos-on-the-groups-page-group-shortcode?replies=5](https://wordpress.org/support/topic/team-flagslogos-on-the-groups-page-group-shortcode?replies=5)).
   As by the time it was a very older version I didn’t want to risk messing with
   the current one I have installed. It would be nice if there was a way to take
   out the line around the flag in the prediction sheets as well.
 * Thanks in advance.

 * The suggestion in that forum post still applies, only the line numbers have changed:
   313 -> 292 and 376 -> 366.
    The line around the flag can be removed with some
   extra css in your stylesheet (border: none). But I’ll remove it in a next version
   as well.
 * p.s. Please open a new topic if you have a question. That will help me keep track
   of the status.

 * **Change ranking order**
    Sometimes players end up with the same amount of points
   scored. The plugin handles this in the ranking by making the amount of full scores
   more important than the amount of toto scores (and some other rules). This extension
   shows how simple it is to also include the amount of goal diff points in the 
   determination of the order. It does this with simple string inserts in the SQL
   that calculates the order in the calculation process. But you could also change
   the fields in the SQL or just rewrite the entire SQL. [football-pool-extension-change-ranking-order.php](https://dl.dropboxusercontent.com/u/397845/wordpressfootballpool/extension-plugins/football-pool-extension-change-ranking-order.php)

 * Nice extensions, but I’m not 100% happy with them 🙂
    golden games: Doesnt mark
   match in prediction sheet. pagination: if all game on i.e. first page is finished,
   it shows a blank page. only open matches: when enabled it removes played matches
   from matches overview, not only in prediction page.
 * (I have adjusted plugin to do premier league)
 * Should be nice with a possibility to get a ranking on match types also.. (I use
   match types for every Premier league round)

 * Hi trehesten,
 * these extensions are of course meant to be an inspiration. Not to be 100% accurate
   on the wishes for all users 🙂
 * If you want to change the extensions, or build your own, feel free to use my 
   code as an example. It’s all 100% open source.
 * For questions or problems, please open a new post on the forum.

 * **Shortcode [fp-scores]**
    I created a simple shortcode that displays a table
   with a set of users (vertical) and the scores for a given set of matches (horizontal).
   Code is not optimized and it needs some custom CSS styling because the table 
   can get very large for multiple matches and/or a large user set. This extension
   registers the shortcode, so you can use it in your content.
 * parameters:
 *     ```
       //[fp-scores]
       //  Displays the scores for every user for one or more matches.
       //
       //  Users, match & matchtype arguments can be entered in the following formats (example for matches):
       //        match 1               -> match="1"
       //        matches 1 to 5        -> match="1-5"
       //        matches 1, 3 and 6    -> match="1,3,6"
       //        matches 1 to 5 and 10 -> match="1-5,10"
       //
       //    league    : the league to get the users from, defaults to the overall league
       //    users     : collection of user ids, if set then league setting is ignored
       //    match     : collection of match ids 
       //    matchtype : collection of match type ids
       ```

 * Excellent Shortcode [php-scores]
    I wonder if instead of putting the names of
   the teams, you can put the flag? I code exchange. Thank you so much

 * Yes, that is possible. Plugin contains classes to get all information for a team,
   so you should be able to alter the code and show the flag.

 * **Report**
    The following example shows a simple way to show data from an SQL
   query in the admin (for reporting/information). It adds an extra page in the 
   Football Pool menu and outputs the query results in a table. The query in the
   example shows number of predictions per user, but you can show any information
   if you change the $sql variable to your query.

 * **User Search**
    This example adds a very basic user search to the ranking page.
   Use it as an example for your specific needs.

 * **Fix for Scripts To Footer plugin**
    Not really an extension, but more a fix
   when using my plugin together with the [Scripts To Footer](https://wordpress.org/plugins/scripts-to-footerphp/)
   plugin. The STF plugin moves all javascript files to the bottom of the page and
   this causes a problem if you’re using the countdown function in my plugin. Fortunately,
   the author of the plugin has a way to exclude certain scripts from being moved:
 *     ```
       add_filter( 'stf_exclude_scripts', 'stf_custom_header_scripts', 10, 1 );
       function stf_custom_header_scripts( $scripts ) {
       	$scripts[] = 'js-pool';
       	return $scripts;
       }
       ```
