Inserting a record via a hyperlink into a mySQL database

I've spent the day playing with MySQL and linking to the database via a local ODBC connection - all seems good.  I will be sending out a hyperlink (something like); http://www.xxxx.com/mypage.php?TSID=123456

I now have a test ID database, configured in the following way:

Database name: test1
Username: user
Password: password
Table name: TS1
Field name: Field1

Could someone give me a really basic example of the html page and the PHP page containing the code (I'm really new to this).  Ultimately, I need to know how to get the '123456' into Field1 (as a new record).

Thanks as always.

Here's a quick & simple code that you can use.  I did not include any data validation but noted where you can add them if you wanted to.  The validation would occur server side but you can easily add javascript to do client side validation which is what I would suggest.  But that is beyond the scope of this question, so I'll leave that alone :)
<?php
//connect to db
$dbh = new PDO('mysql:host=localhost;dbname=test1', user, password, array( PDO::ATTR_PERSISTENT => true ));
 
if(empty($_GET['TSID']) == FALSE)
{
    $tsid = trim($_GET['TSID']);
    $return_message = 'TSID: ' . $tsid;
 
    //Do some validations here is desired
 
    //Insert into db
    $sql = 'INSERT INTO TS1 (`Field1`) VALUES (:tsid)';
    $rslt = $dbh->prepare($sql);
 
    if($rslt->exec(array('tsid' => $tsid)) or die(print_r($rslt->errorInfo())))
    {
       $return_message .= ' has been inserted into db.';
    }
    else
    {
       $return_message .= ' was not inserted into db.';
    }
 
}
 
//Output html
print <<<HTML_CODE
<html>
<body>
<div id="return_message">
$return_message
</div>
</body>
</html>
HTML_CODE
 
exit(0);
 
?>

My apologies, I left out a ";" on line 36 of the code
<?php
//connect to db
$dbh = new PDO('mysql:host=localhost;dbname=test1', user, password, array( PDO::ATTR_PERSISTENT => true ));
 
if(empty($_GET['TSID']) == FALSE)
{
    $tsid = trim($_GET['TSID']);
    $return_message = 'TSID: ' . $tsid;
 
    //Do some validations here is desired
 
    //Insert into db
    $sql = 'INSERT INTO TS1 (`Field1`) VALUES (:tsid)';
    $rslt = $dbh->prepare($sql);
 
    if($rslt->exec(array('tsid' => $tsid)) or die(print_r($rslt->errorInfo())))
    {
       $return_message .= ' has been inserted into db.';
    }
    else
    {
       $return_message .= ' was not inserted into db.';
    }
 
}
 
//Output html
print <<<HTML_CODE
<html>
<body>
<div id="return_message">
$return_message
</div>
</body>
</html>
HTML_CODE;
 
exit(0);
 
?>

I'm not quite there yet - sorry.

I created a file called insert.php, that I put onto the webserver (in the same folder as index.html).  I put in the following hyperlink:

http://www.callibre.com/insert.php?TSID=123456

And got the following error:

Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in D:\inetpub\wwwroot\vhosts\callibre.com\httpdocs\insert.php:3 Stack trace: #0 D:\inetpub\wwwroot\vhosts\callibre.com\httpdocs\insert.php(3): PDO->__construct('mysql:host=loca...', 'user', 'password', Array) #1 {main} thrown in D:\inetpub\wwwroot\vhosts\callibre.com\httpdocs\insert.php on line 3


Any help would be really appreciated - I'd love to get some form of process in place today.

I haven't used odbc myself but give the code below a shot.
<?php
//connect to db
$connect = odbc_connect("test1", "user", "password");
 
if(empty($_GET['TSID']) == FALSE)
{
    $tsid = trim($_GET['TSID']);
    $return_message = 'TSID: ' . $tsid;
 
    //Do some validations here is desired
 
    //Insert into db
    $sql = 'INSERT INTO TS1 (`Field1`) VALUES (?)';
    $rslt = odbc_prepare($connect, $sql);
 
    if( odbc_execute($rslt, array($tsid)) or die(odbc_errormsg($connect))
    {
       $return_message .= ' has been inserted into db.';
    }
    else
    {
       $return_message .= ' was not inserted into db.';
    }
 
}
 
//Output html
print <<<HTML_CODE
<html>
<body>
<div id="return_message">
$return_message
</div>
</body>
</html>
HTML_CODE;
 
exit(0);
 
?>

Thank you for your help on this one - really sorry for the delay in getting back to you.  I still haven't got round to adding the functionality to my app, but I will use your examples when I do.  Really appreciated and thank you once again.
