Help need in generating PHP reports

Hi,

I am creating reports in my project using TCPDF. I want to get the reports on a daily basis. For an example if there are 10 transactions occurred in a day, i want to display them in a report format.

These are the 2 pages that i have created. The following error message displayed

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\MySite\php files\tcpdf\examples\transaction_report.php on line 37

while($row2 = mysql_fetch_array($this->result))
