Create a button in a custom file (v2023)

[twuc]

I've created a button in a custom file to carry out a specific action (and avoid displaying the edit page).

                    <form action="LeagueEdit/<?php echo $league_id ?>?season_id=<?php echo $season_id+1 ?>" method = "post"> 
                    <input type="submit" value="Season Roll-Forward" class='btn btn-app bg-white'>
                    </form>

but get an Invalid post request.
I'm not surprised from a security perspective, but where do I look to find out how to do this? phpmaker2023
Many thanks.

You may read Check token for form post.

Thank you. I've changed the code:

                    <form action="LeagueEdit" method = "post"> 
                        <input type="hidden" name="league_id" value="<?php echo $league_id ?>"><!-- comment -->
                        <input type="hidden" name="season_id" value="<?php echo $season_id+1 ?>"><!-- comment -->
                        <input type="hidden" name="<?= $TokenNameKey ?>" value="<?= $TokenName ?>"><!-- CSRF token name -->
                        <input type="hidden" name="<?= $TokenValueKey ?>" value="<?= $TokenValue ?>"><!-- CSRF token value -->
                        <button type="submit" value="Season Roll-Forward" class='btn btn-app bg-white'>
                        <i class='fas fa-wand-magic-sparkles text-orange'></i><p> Season Roll-Forward</p>
                    </form>

I can see the parameters are correctly set, and 'check token for form post' is set, but now get redirected to the list page (status 302).
Am I missing something?

You have wrong "action" attribute value, you need to pass the primary key in the URL as route value (e.g. LeagueEdit/<?= urlencode($league_id) ?>).

Thank you, that now takes me to the edit form and has answered my question.

What I hoped the code would do was submit the edit form with the parameter supplied and make use of existing server events. It's not the end of the world because I can create a custom file and execute the relevant server events which is probably a neater solution.

However, I have two remaining questions:
Firstly is it possible to pre-populate the fields in the Edit form with the input values?
Secondly, is it possible to submit and save 'LeagueEdit' without displaying the form using the parameter input values?

My last reply,

However, I have two remaining questions:

calling a form from a form makes no sense at all! The way forward is to create a Custom File to do the updates.

Many thanks for your help.
