Re: [PHP-DB] Variable variables ! - help
I've got a loop which includes the following coming from mySQL
if ($art_nr1 != '') {
$i++;
echo "
td
input type=\"hidden\" name=\"art_nr_$1\" value=\"$art_nr1\"
input type=\"text\" name=\"quant$i\" size=\"3\" maxlength=\"5\"
/td
";
I've now got the following
art_nr_1=12456
quant1="" or 1 or so
And now comes the bit which doesn't work !
for ($i=1; $i50; $i++) :
$varid = "quant".$i ;
if ($$varid != "") {
echo
"input type=hidden name=\"art_nr\" value=\"$art_nr_$i\"
input type=hidden name=\"quantity\" value=\"$quant$i\" ";
}
endfor;
This gives the result
input type=hidden name="art_nr" value="1"
input type=hidden name="quantity" value="1"
which is unfortunately not what I want !
I'm sure it's easy but can someone please help !

Re: [PHP-DB] Variable variables ! - help
Hi there:
Not sure this'll work but it's some way towards it I would think:
(Note all occurances of the variable: '$display_this'
//Start off the display item outside the loop
$display_this = "form";
if ($art_nr1 != '') {
$i++;
$display_this .= "
td
input type=\"hidden\" name=\"art_nr_$1\" value=\"$art_nr1\"
input type=\"text\" name=\"quant$i\" size=\"3\" maxlength=\"5\"
/td
";
I've now got the following
art_nr_1=12456
quant1="" or 1 or so
And now comes the bit which doesn't work !
for ($i=1; $i50; $i++) :
$varid = "quant".$i ;
if ($$varid != "") {
//Continue 'building up the varuable:
$display_this .=
"input type=hidden name=\"art_nr\" value=\"$art_nr_$i\"
input type=hidden name=\"quantity\" value=\"$quant$i\" ";
}
endfor;
//Echo thwe variable to the page
?php echo"$display_this"; ?

Re: [PHP-DB] Variable variables ! - help
sorry I don't think I explained that very clearly !
The first loop's on a page which works fine, and it's in a form
with article numbers and then an input field for quantites !
It's the next page that's giving me headaches !
The user submitted the form with all article numbers and some with a
quantity !
And on the next page I just want to display/mail the article numbers with a
quantity !

Re: [PHP-DB] Variable variables ! - help
driving me up the bloody wall !
I'm sure it's something simple !
This works fine
for ($i=1; $i50; $i++) :
$varid = "quant".$i ;
if ($$varid != "") {
echo
"
input type=hidden name=\"art_nr\" value=\"$art_nr_1\"
input type=hidden name=\"quantity\" value=\"$quant1\" ";
}
but the moment I change it to $art_nr_$i it doesn't ???
