I am trying to generate pdf using Fpdf. But i got this error while submitting the button.
Fatal error: Uncaught exception 'Exception' with message 'FPDF error: Some data has already been output, can't send PDF file (output started at C:\xampp\htdocs\AutoMall2\testindex.php:237)' in C:\xampp\htdocs\AutoMall2\fpdf\fpdf.php:271 Stack trace: #0 C:\xampp\htdocs\AutoMall2\fpdf\fpdf.php(1040): FPDF->Error('Some data has a...') #1 C:\xampp\htdocs\AutoMall2\fpdf\fpdf.php(987): FPDF->_checkoutput() #2 C:\xampp\htdocs\AutoMall2\testindex.php(274): FPDF->Output('2017-04-0313.pd...', 'I') #3 {main} thrown in C:\xampp\htdocs\AutoMall2\fpdf\fpdf.php on line 271
