Hi,
Store last postted data into some where in $_SESSION (for example
$_SESSION['last']) then, when user posts a data. check the last posted data
if there are same data reject to record db if not record data to db.
for example (I assume your form field names uses name='postf[fieldName])
Your Php code ...
$process = 'pass';
if(is_array($_SESSION['last'])
{
if($_SESSION['last']['fieldName'] == $_REQUEST['postf']['fieldName'])
{
$strProcess = 'stop';
}
... put there other fields
}
if($process == 'pass')
{
do your sql statement
$_SESSION['last'] = $_REQUEST['postf'];
}
Regards
Sancar

[PHP-DB] Page refresh and database updation
Hi All, I am a PHP newbie. I am using HTTP POST request to send some data to Apache and then using MySql to store that information. Once information is stored in MySql DB successfully, I display a result page. But the problem I am facing is that, if I refresh the result page displayed after database updation, the information is stored again in database which I don't want to. Please guide me on how I can avoid duplication of information in database on refreshing the page. Thanks in advance!

Re: [PHP-DB] Page refresh and database updation
I'm sure there are many ways... a few off the top of my head. a). if there is some field or combination of fields that guarantee uniqueness then you can test for their existence before you insert. b). When you insert the first time set some session variable to something, and then don't insert if that session variable exists. c). have some middle page that does your insertion and then immediately redirects to another page which displays results, but has not more POST data associated with it, so refreshing that page will not cause a re-post of your data.

Re: [PHP-DB] Page refresh and database updation
Hi, one thing u can do is u can have a primary key the table you are inserting so that duplication wont be done. If thats not possible redirect the page to the results page after updating the post data than showing him the results in the action page ( action i mean where the form action has been written ) raj On Tue, 26 Sep 2006, Tamkhane, Pravin wrote: Hi All, I am a PHP newbie.

RE: [PHP-DB] Re: Page refresh and database updation
You can redirect the page to the result page after the data is saved, using
header("Location: successpage.php"). I've used this on several sites. It's a
little extra work but does prevent the reposting of data.
Another option is to use AJAX to send the data to the webserver and then have
the javascript open the result page after the update is complete. I do this on
several of my webpages and it works great.

[PHP-DB] Unicode error with PostgreSQL
I'm getting the following error when PHP tries to insert a Unicode character (the problem word is resume with the accents) into a PostgreSQL database: pg_exec(): Query failed: ERROR: Invalid UNICODE character sequence found (0xe97375) I can't figure out why I'm getting the error. The HTML form is utf-8 and the database is UNICODE, but I'm still getting the error. Is there some problem with the PHP library? Is there a PHP setting that controls character encoding within scripts? Any help would be appreciated. Thanks in advance, Tony
[PHP-DB] Error when trying to connecting to an Oracle database
I am trying to use a program written in PHP but connect to an Oracle
database.
We have a function as follows:
function dbconnect($db, $username, $password)
{
global $siteadmin;
global $db;
// $bob = @mysql_connect($db, $username, $password);
//$bob= oci_connect($username, $password, $db);
// mysql_select_db($db, $bob);
$bob = oci_connect("", "", "devl");
echo $bob;
return $bob;
}
where is replaced with a username and is replaced with a
password. We get the following error:
Fatal error: Call to undefined function: oci_connect() in
/www/WEBUSERS/ics2004/public_html/PHP/Project Manager/dba_copy(1).php on
line 52
Line 52 is $bob = oci_connect("", "", "devl");
Can anyone tell me why I am getting this error?
Thanks

Re: [PHP-DB] Error when trying to connecting to an Oracle database
Hi Janet,
This is a PHP 5 only function. Are you running PHP 5? If not, try using
ocilogon() instead. If you are running 5, then maybe the Oracle library
wasn't included when PHP was compiled.
HTH,
Tony

Re: [PHP-DB] Unicode error with PostgreSQL
So does that mean I will always get that error? There's got to be a way around that. Is there at least a way to detect invalid characters before I try to insert?

Re: [PHP-DB] Unicode error with PostgreSQL
Hi Tony You can use the multibyte aware string functions for processing. There is also a way to make it use UTF-8 encoding, but I forget how just now.
