weird php/mysql[

[birdie]

[code]
$ip = $_SERVER['REMOTE_ADDR'];
$sql = "SELECT * FROM portal_logintrys WHERE ip='$ip'";
$query = mysql_query($sql);
$numrows = mysql_num_rows($query);
$object = mysql_fetch_object($query);
[/code]

I have done this hundreds of times but this script just doesnt seem to worry. no idea why.

any help please

Do we get clues about what it does or doesn't do, or should we guess?

Any errors? Is error_reporting on?

sorry,

[code]
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in

Try displaying the error AND the query:
[code]$query = mysql_query($sql) or die("Error: ". mysql_error(). " with query ". $sql);[/code]

That might point you in the right direction.

The "not a valid resource" error has been driving me up the wall recently.

From what I can tell with my own code so far is that this really means, "I didn't manage to select/update/delete the thing you requested, and it's because you made an error in my code, silly". In other words, it didn't like your query somewhere.

For me it usually means that SQL wanted parentheses somewhere, or a single quote around something, etc. Sometimes what works in one place doesn't work somewhere else (I would say there are gremlins somewhere in my database, but I am sure it has more to do with my relatively NOOBIE status as a PHP programmer).
