Extension plugins for the Football Pool plugin

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

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.

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

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.

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

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.

Order match predictions
Order match predictions by score and don’t show users without predictions.
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

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

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

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

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

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

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.

football-pool-admin-report.php

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