Leaving form action attribute empty <form action="" method="post">

[eluser]aidehua[/eluser]
Often I want a form that submits to the same URI.

Because I'm <strike>lazy</strike> concerned to work as efficiently as possible, I am in the habit of doing this:

Code:

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

or sometimes even just

Code:

<form method="post">

It's always worked fine for me. But sometimes I feel a bit guilty about doing it.

Is it wrong? If so, how wrong? More to the point, what could go wrong?

In my opinion it's correct - I do the same

I feel guilty too, but I use it that way. I can't think in something that can be wrong using this.
