Add the following content under $ attachexists = $ ispaid = FALSE;
If (! Empty ($ checktwo )){
At the end of?> Add
} Else {
Echo "<script> alert ('write the content you want to prompt ') </script> ";
Echo "<META HTTP-EQUIV = \" Refresh \ "CONTENT = \" 0; URL = $ PHP_SELF? Checktwo = 1 & aid = $ aid \ "> ";
}
