Odd occurence with extra variables in GET form

[Sugapablo]

I have the following HTML form:
<form method="GET" action="modules .php">
<input type="hidden" name="name" value="Catalog" >
<input type="hidden" name="task" value="addcart" >
<input type="hidden" name="item" value="1">

<P>Available option: thing b - $44.90
<input type="checkbox" name="y0" value="6"></P>
<P>Available option: thingc - $-3.00
<input type="checkbox" name="y1" value="7"></P>
<P>Available option: thingd - $2.80
<input type="checkbox" name="y2" value="8"></P>

<input type="hidden" name="cnt" value="3">
<center>
<input type="image" src="cart.png" value="Submit">
</center>
</form>

When I submit the form, lets say I check off the first and the third
checkboxes, I get the following querystring:

?name=Catalog&t ask=addcart&ite m=1&y0=6&y2=8&c nt=3&x=48&y=4

Where in the world are x=48 and y=4 coming from?

They seem to be coming from the position I click on the submit image? Is
this right? Can someone point me to a page talking about this, I can't
google anything?

That's correct, yes.
http://www.htmlhelp.com/reference/ht...rms/input.html - about 2/3
of the way down.

Incidentally, wouldn't value="Add to Cart" be friendlier than
value="Submit"?

Order forms are not normally idempotent. method="POST" is likely more
appropriate.

Since this is not a paragraph, <P> markup is inappropriate. How about
this?

<div><label>Ava ilable option</label><input ...></div>

Of course. That's pretty much as the HTML spec requires.

Why? Is Google not responding? I'd start at the w3c's HTML recommedation:

http://www.w3.org/TR/html4/

Particularly, the section on forms:

Typed that way too fast. That would not be very useful. This is better:

<div>
<label for="y0">Availa ble option</label>
<input name="y0" id="y0" type="checkbox" value="6">
</div>
