Re: [PHP-DB] pg_insert tyro question

2005-08-23 Thread Jon Crump

Micah,

As a tyro, I'm curious AND cautious: belt AND suspenders is best.

When you say:

assign the values needed into another array before submitting to  
the database


I presume you mean something like this, yes?

/*Create arrays for each of the tables*/
$coretable = array_slice($_POST, 0, 33);
$creatable = array_slice($_POST, 33, 5);
$subjectable = array_slice($_POST, 38, 2);
$stypertable = array_slice($_POST, 40, 2);
$cultable = array_slice($_POST, 42, 2);
$matertable = array_slice($_POST, 44, 6);

But while my own sanity is _certainly_ in question (I rue the day I  
agreed to do this project, however educational it has been), You seem  
to be using sanity check in a technical sense. What exactly would  
that be, when it's at home, and what would it look like?


Thanks all for the good advice!

Jon

I certainly agree with that Micah.  array_pop only removes that  
last item.  If you are in a an open environment you definitely want  
to include security checks and form validation.

This is tenuous and insecure, you have no control over the $_POST

the submitting page does, I'd do a sanity check, and assign the

into another array before submitting to the database.

This is also primed for a SQL injection attack.

Bad idea.. IMHO..

[PHP-DB] pg_insert tyro question

2005-08-22 Thread Jon Crump
Being a tyro, I'm sure I'm missing something obvious about handling the 
array $_POST. I hope wiser heads can point me in the right direction.


This fails:

?php
$db = pg_connect( dbname=foo user=bar );

if( $db )
{
  print Successfully connected to port:  . pg_port($db) .br/\n;
} else {
  print pg_last_error ($db);
  exit;
}

$res = pg_insert($db, 'vracore', $_POST);
if ($res) {
echo You're a Genius;
} else {
  print_r ($_POST);
  exit;
}

pg_Close( $db );
?

The connection string works fine. If I insert each field in $_POST 
separately, that works fine too eg.


$value1=$_POST['value1'];
$value1=$_POST['value2'];
etc...

$query = insert into foo (columnname1, columnname2, etc...) values 
($value1, $value2, etc...);;


$result = pg_exec($db, $query);

But if I try pg_insert($db, 'foo', $_POST);

it fails. I note that print_r ($_POST) returns a list of values that 
includes  [addentry] = Add Entry from the submit button. Is that what's 
screwing it up?


Any clues would be much appreciated.

Jon

Re: [PHP-DB] pg_insert tyro question

2005-08-22 Thread Jon Crump

Thanks mike! that did the trick. This works:

array_pop($_POST);
/* this gets rid of the last element of $_POST which is 'addentry' from 
the form's submit button. $_POST now containes ONLY the values expected by 
pg_insert. By the way, the order of the values in $_POST does not seem to 
matter, only that there are exactly as many as there are columns in the 
table and their names match the columns exactly.*/


$res = pg_insert($db, 'foo', $_POST);
if ($res) {
echo You're a Genius;
} else {
print pg_last_error ($db);
exit;
}

It very likely is the error.  you can use array_pop($_POST); to remove that 
last line.  You can always have your insert function return an error on 
failure. snip /


By the way Bastian and John, thanks for responding to my pg_connect 
question some days ago. Installing Marc Liyanage's distribution did the 
trick!


Thanks too to Bastian and Micah.

Or if you need to store all the values, you could normalize the table 

field

into another table.

To further append the previous note,

if you want to insert the array, you need to serialize it
(www.php.net/serialize) to make the array db safe

if you want to insert the individual specific values, you will need to
implode the array with separators (and check the data in the correct 

order

for the field list) or you will need to supply a field list that matches
the array list to ensure the data elements are placed into the correct
columns

I'm not sure what any of this means, but it didn't turn out to be 
necessary.

is php compiled with postgre support? probably not from the sounds of it

I'm guessing you're right, but it's not clear how I could tell. The output 
from ?php phpinfo() ? doesn't really help much unless I know what to 
look for. On the one hand it says that DBX support is enabled and 
PostgreSQL is one of the supported databases, on the other, MySQL support 
is described explicitly, as is ODBC, but there is no similar section for 
the other supported DBs. If php wasn't compiled with postgres support, 
do I have to recompile it? how? Apologies if these questions are naive, 
but I am a rank tyro in these matters.

[PHP-DB] pg_connect gets fatal error

2005-08-13 Thread Jon Crump

Dear all,

I'm brand new at this and I'm trying to get Darwin/Apache/Php/PostgresSQL 
running on my iBook (OS X 10.4.2) with Tiger newly installed. Apache 1.3 
is running fine, PostgresSQL 8.0.1 working fine, PHP 4.3.11 works except 
when I try to call a postgres function I get:


Fatal error: Call to undefined function: pg_connect() in 
/Users/jjc/Sites/PHPtesting/hello.php on line 12


looking at /private/etc/php.ini.default, it looks like postgres is 
enabled, so why doesn't php like any pg_ functions?


I've scoured the faqs and the archives. I've found this question asked 
before, but not answered.


Any help for a tyro?

Jon
