Hi ,
I have a HTML page with a form in which there are some inputs like
these:
input type=text name=xname value="3303"
input type=text name=xname value="9854"
....
input type=text name=xname value="n..."
the name of the input is always the same ( xname )
This generates automatically generates an array named xname in HTML
with all the diferent values assigned to a diferent position.
that sentence is:
a, borked
b, incorrect
the following is in no way legal HTML:
'input type=text name=xname value="n..."'
assuming xHTML it should be:
<input type="text" name="xname" value="n..." />
but that doesn't get you what you want, the name of the
inputs should be 'xname[]' not 'xname' - when the name of each input
is 'xname' php will read in each value overwriting the previous one...
so $_POST['xname'] will contain the value of last 'xname' input in
the page. so:
<input type="text" name="xname[]" value="n..." />
^^----- these are the important chars!
My question is :
How do I retrieve that array from within PHP ?
I've tryed the following
$xname=$_REQUEST['xname'];
and then
echo $xname[0][0] ; // this returns nothing
echo $xname[0] ; // this returns only first digit of the first input
None of the above seem to recognize that xname is ( in HTML ) an array .
Any help greatly appreciated
Thanks
Mauricio

if i understand well you need to get an array from html post
if you use the same name for your html fields you automatically have
an array in $_POST
eg
input type=text name=myfield value="field_1"
input type=text name=myfield value="field_2"
you'll get the array ar_myfield = $_POS['myfield']
you should achieve the same result using myfield[key] in the name of html

Newbe question:
How does one convert an array into a HTML GET request easely? Are

Same for HTML POST requests.
Thanks,
