Check duplicate entry if exist for two field during insert

Hello

I have a data insert page where before inserting the data to the table need to cross check of two fields data whether it is existing in the table or not, (Like UserID & ItemID) if not exist then it should insert othewise it will report an error that entry is duplicating. Could not figure it out, pls help.

What do you want to do if they do exist? Throw an error? You could probably add a recordset to filter on the two columns you want to check, then add server validation to validate that the recordset doesn't have any results. Then the server validation could be used to show an error message if the duplicate was found.

If you wanted to ignore or update instead of insert when duplicates were found, then there are other options for that as well.

Please attach the .php page so I can open it in Dreamweaver instead of using copy/paste in the future.

I see your recordset uses $_SESSION['UserID'] and your insert uses $_POST["userid"]

That may be the issue.

Also you are validating the value of:
$totalRows_duplicatecheck

but with MySQLi the syntax should be:
$duplicatecheck->TotalRows

I think everything else looks correct.

The problem was on $totalRows_duplicatecheck and other part didin't create any problem. Thanks ray, but I think for the duplicate check should have a easy method of wizard, because this is a common issue in everyday life.

It does have an easy option for a single column duplicate check, just not multiple. It is actually fairly uncommon. Search this forum for how many people have asked for it over the past 20 years.
