Empty data written into sqlite3 database using PHP

I have a problem with writing the data into the database using PHP. I have the elements which it is not empty and when I write the data by insert into the database, it will show the empty data. I want to input the data into the database when using insert. I hope you can fix this issue for $20. You must show me the evidence as the problem is fixed so I can send you the payment to exchange for the fixed file. Thanks for your interest!!!
