Button action event

Hi everyone:

I'm want to add a button in my module and users can call the custom function by clicking the button. How to connect onclick event with calling function.

Further more, is there anything like listener in Moodle?  I want my function called automatically under specified conditions.

Thanks in advance.

Hi,

For the OnClick, you will need to incorporate Javascript into the module page - See Javascript modules - https://docs.moodle.org/dev/Javascript_Modules

As for listeners, you need the Events API - see https://docs.moodle.org/dev/Events_API.

Hi, Benjamin

In fact, I'm want to call a python script in custome function, which is about Machine Learning. Can I use "shell_exec()" to call it in my function?

By the way, if I want to call the script automatically on a deadline, is there any event related to this in Moodle? Or do I need to define it in modulename / classes / event?

Many thanks for your help.

Hi,

I suppose you could do that - I would be very careful about the data coming form the client - if you do use that.

As for calling the script, why would you want to call it from Moodle if you can just set up a cron (scheduled task) to run the python script directly? If you do need it to be run from Moodle then look at the Tasks API - https://docs.moodle.org/dev/Task_API
