89-92: Validate user role before proceeding with permission checks.The addition of a check to ensure the user's role is set correctly is a crucial improvement. This change prevents potential PHP warnings when the roles array is empty or the expected role is not present. The implementation adheres to best practices by checking the existence of the array key before accessing it, which is a common practice in PHP to avoid
Undefined array keywarnings.However, consider adding a debug or error log here to aid in troubleshooting cases where the role is unexpectedly absent. This could help administrators identify configuration issues or unauthorized changes to user roles.

Also, shouldn't it be checking all of the roles and not just the presumed first one? Or probably better yet, just using |

Hey @rinatkhaziev and @WPprodigy, thank you for chiming in and for your suggestions. I don't remember why I ended up using We can then see if any of the proposed solutions are better and act accordingly. Let me know of your thoughts. |

In some cases, this code could be called before the user object would be initialized properly. Haven't tested, but I don't know if |

@rinatkhaziev @WPprodigy thank you both for your feedback! Since it's actually possible to have multiple roles, I did some changes to the permissions checking to handle that scenario. A good side effect, is that it should also handle when there are users with invalid roles, which seems to be the case of the warning. I have tested these changes locally, with a user that had two roles, and it is working as expected. @acicovic what do you think of this solution? |

This looks good to me provided we want to have a permissive approach (the role with the most privileges wins). I'm wondering though if this could raise edge cases (some customers wanting a restrictive approach instead), which would also warrant some UI work. We could provide this in the future though, if we stumble upon it. Thoughts? |
That's a fair point. However, having multiple roles on the same user is not something that is supported out of the box, it requires either a plugin or custom code. I think that, in that scenario, we could offer them a filter, and they can tweak it to their needs. |

Agreed that this is an edge case. Hopefully we may never need to deal with it. |
Description
There are certain scenarios where the user role might be invalid - the role has been deleted, for example - and therefore, the roles array in the
WP_Userobject might not have any data on the0index.This PR adds an additional validation that checks if this array key is set, and if not, returns false.
This prevents an issue where a
Warning: Undefined array key 0warning can be thrown if there is no valid role associated with the user.Motivation and context
Improve the reliability of the plugin's codebase and prevent PHP errors and warnings from filling the logs.
How has this been tested?
Manually tested.
