[Plugin: Events Manager] Child Plugin: extending/changing admin template files

Hi,

Can you give more details or example that you are trying to work out?

Of course.

For example, the backend page where you create a new event. I want to add e-mail notification, but only, if a certain checkbox at the end of this event-creating page is checked.

E-Mail infos, like subject, message, all the recipients will be put into fields in the setting page of events manager.

Currently, I am doing all this with a specific notification script which sits in an events manager core file and the checkbox and the extra fields are written into core files as well.

After every update of the plugin, I have to put my code in again.

If you want to change output of frontend stuff, like the events registration form a visitor sees, we have the template files to use whatever code we need and save it there. Or we can create template tags and use those.

I need that feature for backend stuff. I don’t want to touch any existing code but extend it with my own ideas. Another thing which sits in the core files right now is an extra short description field for an event that I needed.

The other option realizing this would be to use hooks (filters and actions). I would write hooks that hook into existing functions of this plugin, but as you can imagine, it’s much harder to do that. I’m only getting into hooks and filters and the first option would be much easier: adding stuff to the backend code and let the original one be overwritten.

I know that the author of this plugin would disapprove of this, because changing major backend stuff could break the plugin. But since the “admin” folder within template files folder is already there, I thought it was intended to do exactly this.

It would just be great to get a clue why overwriting admin files doesn’t work and why.

Thanks, Christiane

i wouldn’t advise overwriting the admin files

since we’re going to make events custom posts too, you’d be best off adding meta boxes etc. using hooks.

I advise you check this out first: https://wp-events-plugin.com/tutorials/

which covers adding meta boxes etc. and has plenty of snippets you can probably just copy and adjust

Dear Marcus,

thank you for your quick reply, I’ll check the tutorials. Custom Posts sounds great, looking forward to it!

In general I want to thank you for this amazing plugin, I’ve had too much trouble with others, and I will definitely go pro. I can barely imagine what knowledge and effort you’ve put into this and this project deserves every cent ??

thanks!
