Prevent Multiple Form Submissions

Squiz Matrix Support
1

Matrix Version:5.3.3.0

I need to retro-fit some javascript to a Squiz Form to prevent multiple form submission.

The problem is that all the obvious stuff I try - disabling the submit button when it’s clicked, or when the form’s submitted - prevents the Squiz form from working at all.

Really I’d like to know: has anyone succesfully achieved this, and if so what approach (squiz form settings etc, as well as the javascript approach) did they use?

many thanks

I have discovered the following:

  • Any attempt to disable the ‘submit’ button prevents Squiz from displaying error text
  • If I instead set the submit button to ‘display:none’ on form submission, error text is displayed without problem, the button comes back into view when the page refreshes and a valid form submission will occur.

So there’s a workaround, but it feels really really horrible.
Not going to implement this til next week, so if anyone has any comments…

You could try setting a submission time limit on the details screen of the form contents asset?

Alternatively, it should be easy to do with JS where you add an onSubmit event handler that sets a variable for something like var submitted = true, then on the submit handler you also check if that value is true, if it is, show message saying that the form has already been submitted, please wait…

Has anybody been able to add an error message to the last page of their multi page custom form, that tells users if they have already submitted their form. As I understand it, Matrix will not allow a form to be resubmitted, yet, there is no feedback to the client when this situation occurs. The only clue is that the form does not submit. Is there a keyword for this?

No simple keyword for this unfortunately, but you could always do something with JS perhaps?
