Double click problem

[ngr]

Hello,
We have some customers that click the final confirmation button checkout twice, sometimes i receive the order twice (i have no problem with that because i use an offline payment processor) but sometimes the customer and the shop owner never receive the confirmation email.

Is there anything that can be done within ZenCart to avoid customer to click twice in th buttons?
Thanks,
Nicolas

What version are you running? 1.3.7 has a built-in JavaScript function to disable the submit button for a few seconds after being pushed. It's actually been in there since at least April '06.

Take a look at includes/modules/pages/checkout_confirmation/jscript_main.php. In there you should find the function submitonce().

Then, go to the template file (includes/templates/YOUR_TEMPLATE/templates/tpl_checkout_confirmation_default.php) and make sure there's a call to that function in there...

echo zen_draw_form('checkout_confirmation', $form_action_url, 'post', 'id="checkout_confirmation" onsubmit="submitonce();"');

If any of that stuff is missing, you're running an older version, and need to upgrade.

hi,

im having the same problem

we got some code from our payment gateway provider, wont mention who.

their code is a mess and a hack at understanding at how zen cart works.

they have somehow disabled that script and now the form is using

onsubmit="return CheckOk()"

i cant bloody find where to change it back

If you were able to find out what the onsubmit attribute is currently set to, then I'd say you already found it. Or am I missing something?

You need to set that to onsubmit="submitonce();", and make sure that the page setup (includes/modules/pages/[PAGE NAME]) includes the javascript as I described above.

I am having the same problem with multiple clicking on the confirm button at the end of checkout.

I have version 1.3.7 and the submitonce javascript is all there however this script only seems to work in Firefox. When you go through checkout using Internet Explorer you can click on the button many times and you get a many order each with a different order number but the same items.

Is there any different code to stop this in IE?

Same problem here.

I'm running v1.3.7 with the submit_once jscript in place. All bounces are from custommers using I.E.

I use Google Analytics and the Analytics server has been slow recently, which seems to be making customers panic and press the submit button a second time.

It's likely something that IE7 broke. I honestly wonder if they're even trying anymore...

Are you guys using a graphical submit button or an <input> tag? If you're using a graphic, try switching to an <input> and use one of the multitude of JS scripts out there for disabling a submit button.

A slow page change will cause folks to become impatient and click multiple times. You may want to add a warning to the page to only click once and to wait.

Does this mean that there is no js double click prevention built in after all? I thought 1.3.6 and newer Zen Cart versions included some js code to prevent double clicks. But I know little about js, so I may very well be wrong.
