Re: Parsing variables and HTML

[John Brooking]

<P> Daniel,
<P dir=ltr style="MARGIN-RIGHT: 0px">&nbsp;&nbsp; I'm
assuming you mean that you want your three crud
parameters passed through, in which case, your
intuition at the end of your message is correct.
Remember that HTTP is by default stateless, meaning
that when the form that was output by first() is
submitted, your script has no memory that is was ever
run before. It only knows what was in the latest
request. So you need to include more hidden fields in
your form in order to preserve them between
invocations of the
script:<BR>&nbsp;&nbsp;&nbsp;<BR>&lt;input
type="hidden" value="$crud1"
name="crud1"&gt;<BR>&lt;input type="hidden"
value="$crud2" name="crud2"&gt;<BR>&lt;input
type="hidden" value="$crud3" name="crud3"&gt;</P>
<P>Note that by default, $variables expand in "Here"
documents the same as in&nbsp;double-quoted
literals.&nbsp;&nbsp; </P>
