导致此modx错误的原因是什么？

Question

I have the strangest error, a simple import/export script in a modx site is causing some very strange behaviour. here is the script:

    }

    //$mysqli->close();
}


?>

The problem was that it was not populating the "GA" field in the import, everything else runs fine.

The line where I echoed out the script selecting the "GA" value outputs records like this:

select ga from modx_gssi_inventory_gage where 0.182 >= min and 0.182 <= max = Resource id #10 

If I run the query against the modx_gssi_inventory_gage table, I get the expected result an integer not "Resource id #10"

• notice that this script is not even aware of modx & should not be returning Resource Id anything.
• it is run stand alone, nothing calls it just point a browser at the script.
• I can run this from a domain that does not even have modx installed & it will still come back with this weirdness.

Any thoughts as to what is going on with this???

Answer 1

$GA = mysql_query("select ga from $gatable where $MINGAGE >= min and $MINGAGE <= max;");

That should return a resource, and it does. You need to process that result before you can use it efficiently.

$row = mysql_fetch_assoc($GA); $GA = $row['ga'];

See PHP's page about it.
