html - Forms with action=""

Question

I just found out (the hard way), that when you have a HTML form with action="", Webkit browsers treat it differently to Firefox and Internet Explorer.

In FF and IE, these two form tags are equivalent:

<form method="post" action="">

<form method="post">

They will both submit the form back to the same page. Safari and Chrome however will send that first form to the default page (index.php, or whatever) - the second form works the same as FF/IE.

I've quickly hacked my code so that anywhere where it would normally print an empty action, it doesn't add an action attribute at all.

This seems very messy and not the best way to be doing things. Can anyone suggest a better method? Also, can anyone enlighten me about why Webkit would do such a thing?

Answer 1

I usually use

<form method='POST' action='?'>

This means the current URL but with no parameters.
