Description Luca Tomat 2011-03-31 21:34:40 UTC
in the HTML standard (the one web-developers read) you state that the input element has a "name" attribute and since the type="image" is a subclass it is reasonable to expect it present there too.

But in the implementation standard (the one web-browser-developers read) (point 3.3) the "name" attribute is excluded.

Here we have two standard documents in contraddiction with each other.

Which one is right?

Please see this bug report too:

HTML4 is an obsolete standard.  Don't read it anymore - use the HTML5 standard, or the developers view of it <>.

In any case, I have no idea what you're talking about re: <input type=image> and @name.  Point 3.3 in the algorithm you link to explains precisely how to deal with the 'name' attribute on <input type=image> when constructing the form data to be submitted.

If there is a problem that I'm somehow missing, can you elaborate?
Comment 2 Luca Tomat 2011-03-31 22:03:21 UTC
Point 3.3 says that the name attribute should be converted in name_x and name_y but it also says to "Skip the remaining substeps for this element" and this means, as i understand it, not to elaborate point 4 which is the point that states the "name" attribute should be sent too.

From a server side, when i have a regular "input" tag, i'll receive the "name" field too, but when i have a "input type=image" tag i'll receive only "name_x" and "name_y" but not "name".

In the HTML 4.01 standard i linked it doesn't say in any place that when the input type is "image" the "name" attribute should not be sent (together with name_x and name_y). Did this change in HTML5?
Comment 3 Tab Atkins Jr. 2011-03-31 22:17:41 UTC
It didn't change; HTML4 was just insufficiently precise.  (That's par for the course in HTML4 - *many* things are insufficiently defined.)

HTML5 just defines the actual behavior more precisely than HTML4 did.
