Hi,
Im a newbie on PHP / MySQL programming and Im running a script to search one field on my DB table. The results will show after I key in my search word but there's an error below that says: Undefined variable: PHP_SELF in C:wampwwwITInventoryApplicationITInventoryfilesSearchSerial.php on line 105. Also the link to the next page is not clickable.
When I change to $_SERVER['PHP_SELF'] I get:
Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING'.
Pls help me... thanks.
