PHP avoid duplicates caused by long load

Question

I have a site where you can submit data into the db. Everything works fine but sometimes when I click to submit it takes long time. I noticed that some people try to click submit a couple of times while it is still loading and this way they insert the same entry more times in the database.

What is the solution for this problem?

No idea why this was downvoted; it's a perfectly reasonable question, even if somewhat open-ended. — Jon, Aug 21 '14 at 11:44

You can disable the button after the user submitted the form.

Here is a SO question/answer whith an example:
Disable button after submit with jQuery

If you don't use jQuery already you might use a vanilla js solution instead.

actually, I can't use this because I have a validation in place. So in case someone doesn't fill something, the submit button will become un-clickable for the second push. – Grasper Aug 21 '14 at 14:22
I guess I will need to implement it within the validation script. So your answer is still valid... – Grasper Aug 21 '14 at 14:28
