[SOLVED] "User name in use" error on cart registration process with IE11

[grog24]

Hi,

I've installed for test the latest full package version VirtueMart2.6.12.2 + Joomla_2.5.27 on my server using debian 7, PHP Version 5.4.34-0+deb7u1 and mysql 5.5.40-0+wheezy1.

When I try to register through the cart at the page /index.php/account/editaddresscartBT using IE 11 on win7 I get the error "User name in use" but the registration is completed even if there is not the message "Registration Completed!".
If in the same process I make a mistake (for example I leave a required field blank) and then I click register, the message  "required field is missing" appears, then I fill the field and I click register again, this time the registration is completed with no error and the message "Registration Completed!" appears.
Every time i try this process I delete the user from joomla and clear cache/cookies on the browser.

There are no problem with other browser.

The problem happen on older versions too as stated on this topic (http://forum.virtuemart.net/index.php?topic=119373)

I hope for solution, thanks!

edit: Solved in VirtueMart 3.0.0

I just found the reason. We need to prevent the default behaviour of the submit button, because the JS is doing it.

Search in edit.php and edit_address.php for

<button class="button" type="submit" onclick="javascript:return myValidator

change the type to button

<button class="button" type="button" onclick="javascript:return myValidator

hello, I have a similar problem with the registration, when I register with IE, I get redirected to the home page     . This is inconvenient because then the customer must return the cart..., while with firefox or other browser this does not happen and after checking I can continue buying without problems .. thanks
Now i use 2.6.12.2 VM

Thank you!

with your fix the error is gone.

In my particular case (I'm using HTML5 Form Validation) I've removed "f.submit();" from myValidator function instead of changing button type. With this only safari complain (do not register), so with:

Code Select Expand

<?php if(preg_match('/Safari/i',$_SERVER['HTTP_USER_AGENT']) and !preg_match('/Chrome/',$_SERVER['HTTP_USER_AGENT'])) { ?>
f.submit();
<?php } ?>

I put back "f.submit();" only for safari and all is working!

Thanks again

Thank you for this hint.

If we consider this: http://stackoverflow.com/questions/1357118/event-preventdefault-vs-return-false
Then I think it is even easier. Just let the type be input again (replace the type="button" against type="input") and remove the f.submit();

The return false does the rest.

The safari problem was my fault, now f.submit(); is no more. I tried both with type="input" and with type="submit" and it works with both.

So in the end to solve this error we have just to delete "f.submit();" in myValidator function from the file edit.php and edit_address.php (under the folder /components/com_virtuemart/views/user/tmpl).

I think the solution is this one

//We must return here false, to prevent that the form is sent again. We cannot just return true without using f.submit, because then the task is not set
f.submit();
return false;

because we do before
f.task.value = t; //this is a method to set the task of the form on the fTask.

and the changed task is not in the form sent by the button.
