Error logged: Undefined index: Qform__FormCallType
So I set up the error logging tools (very useful) but I've noticed a strange error getting recorded a few times each night. I am unable to replicate this error. I was wondering if anyone else has experienced this. Perhaps some sort of bot is causing it?
Here is the error:
Undefined index: Qform__FormCallType
Error Type: E_NOTICE

This is actually an error that I myself have seen sporadically. On a moderately-trafficked site, I'd see this two-three times a week; I'm pretty clueless as to what may be causing it. If you come across a reliable repro, I'd be very interested to hear about it (do open a ticket). Thanks!
I once had the same error and it came out, that service provider had some kind of a restriction about POST variables. I had a page with hundreds of textfields. When I removed some of them, things were working fine. So, it came out, that maximum 64 POST variables were allowed. Because I had 100 textfields, QCubed variables were never received by the server after the request (first 64 was sent).
Though I'm not sure that there cannot be other cases for this.
I have similar error long time ago in my production site.
It is usually caused by incompatible browser such as using certain mobile phone browser or any browser with disabled javascript.
I modified my custom QCubed 1.1 (originally from my custom QCodo 3.43) like this
Original QFormBase::Run line 157-162 (QCubed 1.1)
if ($objClass) {
global $$strFormId;
$$strFormId = $objClass;
$objClass->strCallType = $_POST['Qform__FormCallType'];
$objClass->intFormStatus = QFormBase::FormStatusUnrendered;
I derived this in QForm::Run() - by copying the whole Run() from QFormBase with modification like this:
if ($objClass) {
global $$strFormId;
$$strFormId = $objClass;
if (array_key_exists('Qform__FormCallType', $_POST)) {
$objClass->strCallType = $_POST['Qform__FormCallType'];
} else {
echo QApplication::Translate('Your request cannot be processed due to incompatible browser or disabled javascript in your browser.');
exit();
}
$objClass->intFormStatus = QFormBase::FormStatusUnrendered;
Is there any valid work around for this issue besides simply telling them they don't support javascript? I have a task to develop a mobile version of an app, and I'm running into this issue with some of the 'older' mobile devices I'm testing with.
Thanks, as always!
Currently no, but we're trying to ensure v2.0 works without javascript as much as possible, watch the status of this ticket:
