No support for mysqli on remote server - and I have a problem

Hi all,

I have PHP 5.whatever on my local  machine, the host for a site I'm working on seems to have PHP 4 - or at least it doesn't support the mysql object (when I use mysqli_connect it claims that it is an undefined function).

So I'm just using the standard mysql_connect.  Now, the mysql link seems OK, because in the included database connection definition file, I put in this code:

$dbc = mysql_connect('localhost','user','pass','db');
if (!$dbc){
      echo 'problem';
}

Problem does not get echoed.

In the problematic file (which, by the way, is a form), I've echoed the SQL that is being generated and plugged that straight into the database.  When I do so it works fine.

So somewhere there is a problem, in the code attached below, because 'problem2', as below, DOES echo.  The query syntax is fine, the link SEEMS ok, so where is the problem in the 3 lines in between?

Thanks a lot.  This is driving me a bit nuts :)


$q = "INSERT INTO users (first_name, last_name, company_name, email, telephone) VALUES ('$firstname', '$lastname', '$company', '$email', '$phone')";
		$r = mysql_query($q, $dbc);
		$num = mysql_affected_rows($dbc);
		$id = mysql_insert_id($dbc);
		if (!$r){
		echo 'problem2';
		}

instead of:
$r = mysql_query($q, $dbc);

try:
$r = mysql_query($q, $dbc) or die( mysql_error() );

what errors do you see?

"No database selected".

Thanks, that was a good idea.

Am I right in guessing that mysql_connect doesn't take a database as the 4th argument, like mysqli_connect does, and so I have to use mysql_select_db?

I hope I am.

Will try igt.

$dbc = mysql_connect('localhost','user','pass') or die( mysql_error() );
mysql_select_db('db') or die(mysql_error());
