input type="image" $_POST queries

Re: input type="imag e" $_POST queries

Since your using an image in an input field then that information is
being submitted by post to (the image is). Thats fine, just access each
post variable indivually (yes it takes a bit longer but as you have
seen IE and FF differ)

so just get your vars as so: $submitedname = $_POST['name'];

This is working but I'm not happy basing this on the x co-ordinate

If you wanted to implement a similar icon based 'Control Centre' what
approach would you take? The intent is to have a single page where the
site admin can add/edit/delete news, articles, bios, user data, etc

"Creates a graphical submit button. The value of the src attribute specifies
the URI of the image that will decorate the button. For accessibility
reasons, authors should provide alternate text for the image via the alt
attribute.

When a pointing device is used to click on the image, the form is submitted
and the click coordinates passed to the server. The x value is measured in
pixels from the left of the image, and the y value in pixels from the top of
the image. The submitted data includes name.x=x-value and name.y=y-value
where "name" is the value of the name attribute, and x-value and y-value are
the x and y coordinate values, respectively." From:

Forms in HTML documents

http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.4.1

Note that php will convert name.x to name_x and name_y since period is
invalid in variable name.

What I'd like to know is what happens in IE if images are disabled or
non-existing image uri is given, and form is submitted by clicking the image
input which is converted to normal submit button, is the actual name then
provided? Are the coordinates (0,0) provided?

Kimmo, I just disabled images in ie6 so I'm only see the placeholders. It
still works as though the image was there (ie getting the x and y coords).

thanks for your help,

I'd be inclined to make them buttons and use CSS to style them out to
be images (turn off the borders, specify a width and height, set a
background-image). From there you can either use them to sumit to a
page using AJAX, JavaScript, or a plain old form.

I'd be inclined to agree with you ;-)
Just tried this and it seems much cleaner!!
