When you order something on this site, by clicking on the "Buy it" image button, you seem to get ordered double quantities, where you would expect 1 item. See my upcoming testcase. There, I have 4 ways to submit the form. Only the way of submitting by clicking on the input type=image button is causing duplicate entries in the shopping cart (2 instead of 1). I'm not sure if this is caused by a bug in Mozilla, but it is certainly a bit suspect. Reproducible: Always Steps to Reproduce: 1. See testcase 2. Try the different ways of submitting 3. Actual Results: Only the input type=image way is causing duplicate entries in the shopping cart. The other ways not. Expected Results: I expect only 1 quantity in the shopping cart no matter what way I submit the form.
Created attachment 157072 [details] Testcase By the way, this was previously discussed here: http://forums.mozillazine.org/viewtopic.php?t=116467&sid=ba93d7e19f67cf9569774e0edba8e274
I can confirm this bug for Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3 When I tried the test page given by Martijn, the first button duplicates while the rest do not. With the first button, I observed that for an instant the quantity is correct and then the page re-refreshes (or at least it seems to) and the quantity increases by 1. This also occurs for me at http://paylessdial.com on Linux. However, another poster on the mozillazine forum stated that he did not see the bug on Windows for the same version of Firefox for the same website.
Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a3) Gecko/20040817 I clicked the first link, and the shopping cart was loaded with 1 item only. I continued shopping using the link at that site, used the image button to buy a MS optical mouse for 8.5, the cart loaded and was showing quantity three mice. I don´t remember if that mouse has been the item in your testcase, I don´t think so. Buying a USB watch added two of them to the shopping cart. BTW, you don´t need the &sid part in the mozillazine links, thats only a session id. http://forums.mozillazine.org/viewtopic.php?t=116467
Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a3) Gecko/20040826 bug is seen on Mozillazine too, I saw some double posts, and when I was making a post, I also found two afterwards, and submitting twice never has happened to me, so it must be Mozilla ;-) tested Buy Button in testcase again: it gave me an order for 1 USB mouse. Continued shopping at the website, ordered another one and found 3 in my cart.
Chances are that this bug is the same as bug 256953. Note that the code for image submit inputs on trunk is completely identical as far as I can tell, so I don't see how a double-submission would be caused by the image but not the submit button. All that said, I can't reproduce the problem at all in a vanilla 1.8a3 release build on Win98.
Depends on: 256953
I tested it again. But now I get duplicate quantities with "Buy it with submit button" and "Buy it with simple link". I guess, it probably just happens randomly, or something. Just wondering if it might have something to do with bug 137155.
I have posted some info under a similar bug that may be of some help. https://bugzilla.mozilla.org/show_bug.cgi?id=256953
