HTML , action = ''', irregular response to form submit

Question

I have a form on page www.mysite.com/myPage.php that mosttimes works but occasionally sends the form to the index page.

This is because I-m using the html 4.x style < action "">.

So what is the best generic option (not specifying the page url) to keep the form to the same page? Html would be cleaner than php, no?

The following question is 3 years old and has no accepted answer (Forms with action="")

• Alex Shilman: Action=""?, In the action attribute of your form put ./myPage.php
• EnglishAdam: blank action"" should redirect to same page
• AeroX: @Gamemorize A blank action="" attribute leaves it down to the browser implementation. Defining it as the current page is better (See W3 Bug Tracker)
• AeroX: possible duplicate of Forms with action=""
• EnglishAdam: OK, I see that action "" is not the done thing anymore... I-ll accept an answer that replaces it with the latest cross/browser GENERIC mode to have action direct to same page..
