Problems inserting via mysqli to db

I have a big form that needs submitting. There are 2 parts to this question.

1. How can I add the equivalent of this --- or die(mysqli_error($db)) --- to the execute method used with the webassist code in order to display errors with running the query?

2. Some of my fields begin with a number, seeing as there are various sections with the same questions, so for example :
2-income-order
2-income-comments
etc.

Is this a problem with mysql tables?

Thanks very much,
George

1) Update debug to true in the rsobj.php file.
2) Yes this can be an issue. You can fix it by wrapping the column names with ` (the key to the left of the 1) like: `2-income-order`

The dashes would cause issues even without the numbers.

Thanks for the reply... debug seems to be already set to true?
$this->Debug = true;

Also.. where would I enter in the ` ? As in the following ?

$InsertQuery->bindColumn("`1a-knowledge`", "s", "".((isset($_POST["1a-knowledge"]))?$_POST["1a-knowledge"]:"") ."", "WA_DEFAULT");

UPDATE : OK .. just tried this and nothing happened.

This is the trigger :

if ((((isset($_POST[""]))?$_POST[""]:"") != "")) {

I want it to submit and enter.... is this correct?

You would want to enter the name attribute of one of your form fields to check for. It can be any one of them if you want it to capture any submit from the return key lie:

if ((((isset($_POST["FieldName"]))?$_POST["FieldName"]:"") != "")) {

The quotes are in the correct place in your example.

Thanks very much!
