It doesn't look like you're actually retrieving data using the $_POSTed
data from that code snippet. Are you doing anything like $j = $_POST
['j']; in order to get the value of j before you retrieve your array
data? Or are you allowing PHP to declare $_POST variables globally?
Yes, I tried setting the $_POST information to a variable, but that
does not work either. I think I am allowing PHP to declare them
globally... how is that done exactly?
The reason you need brackets is because brackets are always used in the
declaration of a user array, assuming that this is what you want. If
you don't want an array, than your original code was correct -- []
always signals an array type to PHP.

Do you recommend I use an array over a lot of variables? I can use
either or - there was no particular reason why I chose a single
variable.
Thanks,

Hi

Yes, this is how I am checking the post variables.
Your other variables are done as an array - $firstName[$j] etc,
should
your
check box be
echo ' tdinput type=checkbox name=user[' . $j . ']
value=1/td' . \n;
(note the [])
Why do you have to have the []'s? I did add those, but it didn't seem
to help.
Otherwise try vardump($_POST) to see exactly what is being returned.
I also tried the vardump($_POST), and it did not seem to return
anything. I did not find anything about vardump() on the php site...
besides some non-built in function. Any more thoughts on using it?
If this does not fix it try posting the code that handles the
response
and
we will try and help.

Ok, quick question. Does the $_POST variable transfer the information
to all the pages? or just the page called in that form
action=apage.php? Because in my code I call a certain page, but
then
that page merely redirects to another page, depending what selection
was made.
The code that uses the $_POST information follows...
~Philip
?php
for ($j=0; $j=$largestDBID; $j++) {
$user = user[ . $j . ];
if ($_POST[$user]) {
echo 'tr' . \n;
echo ' td' . $dbid[$j] . '/td' . \n;
echo ' td' . $firstName[$j] . '/td' . \n;
echo ' td' . $lastName[$j] . '/td' . \n;
echo ' td' . $uid[$j] . '/td' . \n;
echo ' td' . $username[$j] . '/td' . \n;
echo ' td' . $classification[$j] . '/td' . \n;
echo '/tr' . \n;
}
}

Re: [PHP-DB] Webpage response to selection $_POST
hi...
to what i know, the $_POST variables get passed to apage.php only... if you
have a redirect to another page inside apage.php, the $_POST variables will
not be passed to the next page. you may need to register your $_POST as
session variables inside apage.php first or you append your $_POST variables
to your redirect string...
e.g. header('location: nextpage.php?var='$_POST) or something like that...

[PHP-DB] Webpage response to selection $_POST
Hi all.
I have a list of users in a database that I would like to show on a
dynamic webpage. With each of these users that shows up on the page,
there is going to be a checkbox next to their name so that I can
perform multiple tasks, such as 'Remove User' or 'Modify Information'.
I have all of the appropriate information showing up on the page,
including the checkboxes.
My question is... if I select a checkbox for a user, the other pages do
not even recognize that I have selected that checkbox and I am using
the $_POST method - why is that? I have even attempted to use the
import_request_variables function - no luck. So, I cannot verify which
users I want to perform an action on.
Anyone have any ideas? Snippets of code to follow...
Thanks in advance,
~Philip
