When creating a table in MySQL, we create 3 columns. This column is unique and should be set to autoincrement. It counts sequentially 1 up from any new row of data inserted. So it starts at 1. If you insert 5 rows of data, the fifth row will have an ID of 5. The purpose of it is that it's unique and it gives you a way to order the new uploads in order of when they were uploaded.
You could also do this in other ways. But this is probably the easiest way of showing the files in order from when they were uploaded. The second column that I created was a description column. This holds a description of the file being entered.
Once the user puts a description of the file in the text box and uploads the file along with the description, the description of the file entered will be inserted into the descripton column of the table. The third and final column that I created is the filename column. This holds the full file name of the file.
So if you're uploading a file named records. Since it holds files information, I named the table, 'Files'. You can see the image of the structure of the table below. So you can see the structure of the table above.
The ID column is of type int Sometimes the user may want to put in a somewhat good description of the file, so we allow up to characters.
CHAR is a fixed amount. You would use CHAR when every upload is the same amount of characters.

We will add our additional functionality for generating pdf report from MySQL table here. We will generate pdf report from our MySQL database using Codeigniter but Codeigniter does not provide any built-in functionality for generating pdf report. So we need to use third party library for pdf generation. One such library can be downloaded from the URL tcpdf library. You may delete examples and tools directories from tcpdf directory.
These directories are not required. These default header and footer functions basically print tcpdf logo, author information etc in the generated pdf files. So you may not like to have those information into your generated pdf files.
