Disable submit button to prevent double charge on double click

[[email protected]]

I put this code in my wordpress page to prevent double clicks on the submit button but wordpress just erases it after I save it:

onclick="this.disabled=true;this."

How can I prevent people from submitting payments twice?

Good day!

I wish we could help. We don't have WordPress expertise and as such do not know what works and what does not.

I just did a quick search on the web and here is a link that seem to be addressing this issue: https://wordpress.org/support/topic/...on-form-submit

Hope it helps. API forms are designed by developers and is an open platform. Considering the many platforms and languages employed in doing these forms we are typically out of the loop.

Let us know if we can be of more help.
