name each field with an array name. I know the following works with
checkboxes; try it with text fields:
<input type=text name=poly[] value="">
<input type=text name=poly[] value="">
<input type=text name=poly[] value="">
<input type=text name=poly[] value="">
then, in your php script called from the form, you'll access the polynomials
using poly[0], poly[1], poly[2], poly[3], etc.
You know how many fields were created, because you created them; so you
could pass the number of created fields in a HIDDEN value ($NoPols) from the
form. As you examine each field, you'll determine if it's empty or not.
for( $idx=0; $idx<$NoPols; $idx++ )
{
if( strcmp( "", $poly[$idx] )
{
... do something with field ...
}
}

Subject: RE: [PHP] Novice Question
I wish to create multiple input fields on a single form, I think(sorry
..could you advise?)
I'd like a page that has multiple input fields, but I dont know how to
access the individual inputs.
Say the user wanted to enter three inputs(polynommials in this case)
so they get a page with three input boxes,
Enter polynommial here:
Enter polynommial here:
Enter polynommial here:
How would I dynammicaly create the input boxes and name the inputs. Thanks
for your time on this, I sorry I didnt explain this clearer in the first
place,
Thanks,
Bren
