I am having trouble getting values populated in my form... Here is what I
got so far:

//The values that need to be selected
$result_ip=pg_query($dbconn,$test_query);

What does $rows contain? What does $options contain?

You could also simplify this a little bit. I'd at least remove the
foreach $options loop and use "in_array" - see php.net/in_array

while ($rows = pg_fetch_array($result)) {
$selected = '';
if (in_array($rows[1], $options)) {
$selected = ' SELECTED';
}
sprintf('', $rows[1], $selected,
$rows[1]);
}

Please CC the list so they can suggest things and learn as well.

I meant can you give an example of what they both contain?

I know what they *should* contain - what do they *actually* contain?

Maybe it's just a typo, but your pg_query is returning into the var
$result_ip, while your fetch is referencing var $result (without _ip).
Maybe that's just a typo for your question, but if not, that is at least one
error.

Also, it would be helpful to know what error you're getting....

Randy + Chris:

Thx for the quick replies!

Chris:

$rows contain ip addresses (postgresql inet) type (example: )
$options contain ip addresses (postgresql inet0 type (example:
)
(keep in mind) they are both arrays. $rows contact all ips, and $options contact the ip addresses that were selected

Randy:
I am not sure what you mean. The variables look right. I am getting no errors! Just the logic is messed up.

You could also simplify this a little bit. I'd at least remove the

foreach $options loop and use "in_array" - see

while ($rows = pg_fetch_array($result)) {
   $selected = '';
   if (in_array($rows[1], $options)) {

     $selected = ' SELECTED';
   }
   sprintf('<option value="%s"%s>%s</option>', $rows[1], $selected,
$rows[1]);
}

I think Randy's right.

At the top you have:

//The values that need to be selected
$result_ip=pg_query($dbconn,$test_query);
^^^^^^^^^
but you are doing this:

while ($row = pg_fetch_array($result)) {


$result_ip at the top, $result in the second bit.


If you don't see errors, turn up error reporting & display errors:

error_reporting(E_ALL);
ini_set('display_errors', true);


Also that's not what I meant. I meant add a var_dump or print_r at each
stage to see what you are *really* getting from the code.

Sorry, I may of forgetten to give you this:

This is right before the:

so, my $results is really all the ip addresses ($rows after I perform the
pg_fetch_array).

I will add the var_dump to see it (never done it before, I will do some
googling :) )

Ok, I think you are misunderstanding the process:

=20

1. first, you are querying a database (I assume a postgres db) like
this:

=20

$result =3D pg_query($dbconn, =93select…”) , so,

=20

$result now is a =93resource reference=94 which contains the =
=93result=94 of the
query. However, now you need to tell php to return the contents of that
resource to you (you can return in either an indexed, associative, or =
object
array). So, to get your =93array=94, you now use $result like this:

=20

$myArray =3D pg_fetch_array($result);

=20

Now $myArray is the actual =93row/s=94 you returned in $result.

=20

Does that make sense?

=20

So, when you first query, $result (or $result_ip) =3D pg_query(conn, =
sql), you
need to be consistent with your variables. Either use $result_ip, or
$result, but not both=85.My guess is that=92s your problem.

=20

Hope that helps!

Randy

After your query add it:

$result = pg_query(....)
var_dump($result);

if that's not a "resource" then you have a problem with your query. Use
pg_last_error to work it out.


Inside your loop, add it:

while ($row = pg_fetch_array($result)) {
var_dump($row);
}

Subject: [PHP] HTML FORMS selected questi=
on

I am having trouble getting values populated in my form... Here i=
s what I got so far:

//The values that need to be selected
$resul=
t_ip=3Dpg_query($dbconn,$test_query);

<SELECT    N=
AME=3D"ip[]" SIZE=3D10 MULTIPLE>=0A
<?php
//This will show ALL=
values.
while($rows=3Dpg_fetch_array($result)){
foreach ($options as=
$index =3D> $option) {
    if ($rows[1]==$option)=

    {
echo "<OptioN VALUE=3D\"$rows[0]\" selected=
=3D\"selected\">$rows[1]</Option> \n"; =0A
break;
 &nbs=
p;      }
else
{
    echo "<=
OPTION VALUE=3D\"$rows[0]\">$rows[1]</OPTION> \n";
  =
;  break;
}
}
}

What am I doing wrong?

TIA!

---------------------------

Mag, i'm not sure what is wrong with=
the specific code, however, i'll make a suggestion that i think will help =
you more than just resolving this issue.

i recommend you look into l=
earning a forms class.  the code will be much cleaner and the thought =
process is much more obvious.  the icing on the cake is the increased =
functionality you will get "out of the box" because some smart person coded=
it right into their forms class.  for example, i get client side and =
server side error checking and error message reporting.  i also get to=
have my form give focus to the first element via javascript.  there i=
s some ajaxy stuff i haven't learned yet, but it is
available.

i use Manuel Lemos' free forms generation and validation=
class which can be found on phpclasses.org.  iirc, the license is suc=
h that it can be included in proprietary commercial applications.  the=
re are others, too.  i believe pear has one, along with some other fun=
ctionality.

i'm very glad i went with a forms class instead of "html=
ing" it all.  i think you will be, too.

Manuel has a yahoo mail=
ing list that is very helpful and reasonably active.  Most questions a=
re answered within a day or so.

good luck.
