Learn English – Is “please to remind” a valid construction

Let’s take another example. ‘I command you not to attack before dawn,’ the general ordered his troops would be reported as The general ordered his troops not to attack before dawn. However, what if the original was ‘I command you to not attack before dawn,’ the general ordered his troops? To be faithful to the general’s words, wouldn't that have to be reported as The general ordered his troops to not attack before dawn?

All of your examples with to me are grammatically incorrect. The verb ask takes an indirect object and a direct object, and the indirect object cannot usually be moved to an oblique phrase with to. So the following are correct:

1. Ask me anything.
2. If you ask me whether he was right, I would tell you "No".
3. If you ask me about whether he was right, ....

And the following are incorrect:

1. Ask anything to me.
2. If you ask to me whether he was right, I would tell you "No".
3. If you ask to me about whether he was right, ...

The problem with your question Do you know whether Eric asked me today? is that you've placed me in the indirect object position. This makes for a bizarre question in which you ask your friend if Eric has asked you any questions... which makes no sense. What you meant to say was Do you know whether Eric asked about me today?
