Re: temporary error

In my opinion, variable names are a personal choice, I think the time you loose when writing the name (about a second is long less than the time you gain when, months later, you go and modify the code and you have clear the content and meaning of each variable. In the original code there were no sintax errors, I added some errors when pasting here. Sorry. I have found that in the first execution, it was the $logQueryInserimentoDatiAllenamentoCalciPiazzati that evaluated to false. After having removed the two-field key that I had originally defined for that table and having added an autoincrement key, the problem seems to be solved. Do you find any reason for that?
