have you thought about creating an array of the variables? "chk[$row]" and
then you'd read 'em back like chk["aaa"] or chk["bbb"] or you could loop
through the array with a each statement...
but for variable variables...try ${"chk_".$row}["field"] which should
work...

Subject: Re: [PHP] Dynamic Variable Creation from Forms
Thanks for your response, but that's not my problem. I'll explain
further...
I have a table with the following fields in a row:
aaa
bbb
ccc
ddd
eee
I have a page with a form:
<FORM POST>
mysql_db_query($db, "SELECT * FROM table");
while ($row = mysql_fetch_array($result))
{
echo "<INPUT TYPE='CHECKBOX' NAME='chk_".$row["checkboxtype"]."'>";
}
This will create several checkboxes with the following names:
chk_aaa
chk_bbb
chk_ccc
chk_ddd
chk_eee
ON THE NEXT PAGE, AFTER THE SUBMIT BUTTON IS CLICKED, THESE VARIABLES WILL
EXIST, but I cannot refer to them like this:
$chk_$row["field"]
How can I refer to them??? They can change based on the field data, so they
cannot be considered static variables.
Not *sure* i understand the problem, but this may be the solution:
$foo = "hello";
$bar = "foo";
$foobar = $$bar;
$foobar now contains "hello".
