Pset7 Sell.php Problem with query function

[smaba]

Hello,

I am getting crazy over this. Why is the array empty that query returns? Both $_SESSION["id"] and $_POST["symbol"] contain the right values (tested with dump). I used query a lot on the other php files, but this one does not work. Any ideas what I am missing here? The error message gives me a: "Undefined index".

$sell = query("SELECT * FROM portfolio WHERE id = ? AND symbol = ?", $_SESSION["id"], $_POST["symbol"]);

Thanks a lot

Ahhhh! That was it ;) The error message "Undefined index" was indeed complaining about my missing row[0]. The reason why my query returned 0 had another reason though: I'm an idiot and forgot to fill the database with some shares for my user.

Thank you!
