Looks to me as if you're treating $flen as an array in one place and as a
value in another:
String here:
$flen = $_POST['flen']; // length of text field group, shows to be the
Array here:
for($i = 0; $i < count($flen); $i++)
Remove the count() and you'll probably get what you expect.

Hello;
I am having trouble with a loop in scripts run under
php v5.1.2.
I have produced a form in a web page that has a variable number
of text fields. These fields represent the result of opening a file
and populating the fields with the corresponding value data found
in the file. The field names are generated in a php loop using an
iterator $i and given a_$i+1 names. If I test for the field names
on post literally, a_1, a_2, a_...n, the values are getting posted
properly.
Then when I run through a loop looking for $_POST["a_$z"]
(where $z = $i +1) only one $_POST value with this name
series is processes and the loop quits.
Here is the post processing code at this stage of the script:
$edata = array();
$part = '';
$flen = '';
$file = '';
if($_POST['section'])
{
$part = $_POST['section']; // target file section
$flen = $_POST['flen']; // length of text field group, shows to be the
correct number
$file = $_POST['df']; // file to work on
$z = 1;
switch($part)
{
case 'name':
/*
a_1, a_2 etc are field names
printing these values shows that all the fields are being posted
properly
array_push($edata, $_POST["a_1"]);
array_push($edata, $_POST["a_2"]);
array_push($edata, $_POST["a_3"]);
array_push($edata, $_POST["a_4"]);
could be as few as 1 and as many as 13 fields
*/
for($i = 0; $i < count($flen); $i++)
{
array_push($edata, $_POST["a_$z"]); // this loop terminates on
the first iteration.
print $_POST["a_$z"].'<br>'; // only prints the first in the
series.
$z++;
};
//edit_pa_rec($edata, $file, $flen, $part);
break; -----> more cases with similar code
I want to avoid hard coding the $_POST variables
so, question, is this:
A: a bug?
B: $_POST data is getting dropped in the loop?
C: Something else is wrong with my code?
Thanks in advance
