Error message

Hi,

at the end of the index page there is an error message displayed in the browser:

Warning: mysql_free_result(): supplied argument is not a valid MySQL result resource in /var/www/html/www.name.eu/web/index.php on line 164

The code of line 163-165 is:
<?php
mysql_free_result($Recordset1);
?>

Despite the error message the page works fine.

Deleting the code lines 163 to 165 got rid of the error message. My question is, is it OK to delete the code? Or will this lead to problem?

Thanks for any help
Roxana

Maybe I should mention, that there is no recordset "Recordset1" on the page.

Hi Roxana,

There would be no danger in deleting the code. That code simply would free the result if the recordset actually existed. But since you said there is no recordset on that page by the name - that makes the code trying to free the result to become invalid, nonetheless - which will cause the problem you are describing.

Technically, you don't have to free the result ever (except in cases where a query may be reused over and over). But the main reason it is done is to flush the query from the PHP server memory and allow for more efficient applications, so it is good practice (and also the reason DW automatically generates a free result command whenever a recordset is created).

Warmest regards and Happy New Year,

Brian

Hi Brian,

Thank you for helping me out. I do rely heavily on DW to write most of the code for me. And I usually don't touch any of that code. There are a few more pages that have the same lines of code at the end with no recordset to go with. So I will clean those pages up as well.

Thanks again and Happy New Year

Roxana
