RE: [phpesp-dev] CVS export possible bug

Update: Had a chance to talk to Matthew (thanks to IRC) and he had a very simple and brilliant idea! I think we've figured out what is happening. When I designed this questionnaire, I let phpESP fill in the question names for me. The problem is that I had some question that were worded similarly, i.e. had different endings with the same beginnings. Don't ask me why, I didn't come up with this questionnaire, but I can image some standardized surveys being like that. This became a problem when the names got trimmed to 30 characters and I tried to export data to CSV. Anyhow, I think this is what happed. I haven't had a chance to look at the part of the code that does the naming trick. I thought I would keep you up-to-date, so you won't be looking in a wrong place.

Subject: RE: [phpesp-dev] CVS export possible bug I think I found it! (Haven't fixed it yet tho'). It's in espresponse.inc, response_select_name() function. The problem is in returning $nam array (see line ~651). It's being created couple of lines before with $nam[$key] = $val. I've done the following tests: First: count ($nam,COUNT_RECURSIVE) for $nam[$key] = $val // where $key = question name/label Second: count ($nam,COUNT_RECURSIVE) for $nam[] = $val // notice no variable for index The two arrays have different size, which I believe is incorrect. BTW, the second array has correct data for CSV export. Something happens when we use question names for indexes in the array. I hope all these make sense. I am afraid this behavior might surface somewhere else. James, Kon and others I don't know: What do you guys think about it?

In my case, I am suing Radio Buttons and only two out of 50+ questions getting messed up!
