$ params的php语法错误[关闭]

Question

This is probably a simple question, but I don't even know what search terms to use to find an answer.

I'm trying to update an existing php plug-in in a Learning Management System (Moodle). The code for one part of the plug-in is essentially just a copy of some code from the core code.

Plug in code:

$grade = $assign->get_user_grade($params['userid'], false);

which mostly copies core Moodle code:

$grade = $this->get_user_grade($userid, false, $attemptnumber);

The plug-in is missing the "attemptnumber" parameter, and I want to include it. When I change the code to:

$grade = $assign->get_user_grade($params['userid'], false, ['attemptnumber']);

my code editor says I have a syntax error. What's wrong with it, and how do I fix it?

Answer 1

It probably should be:

$grade = $assign->get_user_grade($params['userid'], false, $params['attemptnumber']);
                                                           ^ (here added $params)
