MSIE 8 and $_POST variable

igorek

I just found this out yesterday. I usually test on Mozilla but for compatibility I tested on MSIE 8 i had to fix a few selector rules but what got me off and furious was that when you submit a form It does not carry the <input type="submit" value="Submit" name="submit" /> In the $POST array so you cant specify the form has been submitted if you use $POST['submit'] as a trigger.

What I did was added <input type="hidden" name="submit" value="Submit" /> and got it working that way but I think that is kinda stupid.

if msie did that it is kind of stupid, the only fields I know of that pass NOTHING if not checked are type="checkbox" and type="radio"

However, I would never depend on the presence of a submit button but only look at it as a tool. forms get submitted by javascript and other ways, and often the "value" is contextual based on whether you are adding or updating.

I always use:

<input type="hidden" name="mode" id="mode" value="updateMember" />

Then I evaluate $mode on the receiving page. It has been a good convention over the years. Note use of id="mode" in case I need to use JavaScript to change it.

Can you provide a sample HTML form you used? I just did a quick test here, and the Submit element showed up just as it always has.

If you submit a form by pressing the enter key in IE the submit button value is not present in the post data. There are other peculiarities too.

To be honest, that sort of makes sense... you didn't activate the submit button when submitting the form, and the W3C standards really only talk about the "activated submit button" being included in the form data.
