POST變量在FF3.6中正確發送，但在FF4 Beta中不能正確發送

Question

誰能想到在Firefox 3.6而不是Firefox 4 beta上正確發送$ _POST變量的任何原因。 我有print_r（$ _ POST）並且這個值在FF4中根本不顯示。 這是輸入的html：

<input type="image" src="images/btn_preview.gif" value="preview" name="buttonPreview"/>

FF3.6中的POST數組的最后一行：

[chkOrganiser] => 1 [buttonPreview_x] => 54 [buttonPreview_y] => 22 [buttonPreview] => preview )

FF4.0中的POST數組的最后一行：

[chkOrganiser] => 1 [buttonPreview_x] => 58 [buttonPreview_y] => 20 )  

Answer 1

參見https://bugzilla.mozilla.org/show_bug.cgi?id=583211 ：

Firefox 4: Html input type image only submits x and y, not name when clicked.

Thanks a lot for this bug report!

However, our behavior is correct according to HTML5, which we're tracking:
<http://www.whatwg.org/html/#form-submission-algorithm>, step 7, substep 3
requires just image-button.x and image-button.y to be appended to the /form
data set/, which will be submitted.

It looks like the specification follows IE and Opera in this case. If you'd
like to see this changed, please submit a bug to
