Generating PDF by using variable from query string with matching data from MySQL table.

We can generate PDF page by taking data from the query string. This way we will pass variables to our script and using that we will generate our PDF page.

Generating PDF document using record from MySQL database with unique id in PHP using FPDF class

Example

We will create a page to show mark obtained by each student by using a single PHP script. Our PHP script will receive student ID from query sting and generate the mark sheet of the student by taking data from the table.

Displaying list of students in a pdf document.

We will be using one similar student list and then on clicking on the name column of the record we will display the Mark sheet of the student. The link we will click will pass the student number or ID to our script. ( Details on adding QR code is explained below )

Google QR Code Service Discontinued

Google has stopped providing QR code generation. However, using the same technique, you can point to other services and generate QR codes.

ID	Name	With QR code
2	Max Ruin	Max Ruin
3	Arnold	Arnold
4	Krish Star	Krish Star
5	John Mike	John Mike
6	Alex John	Alex John
7	My John Rob	My John Rob
8	Asruid	Asruid
9	Tes Qry	Tes Qry
10	Big John	Big John

Inside the zip file you can open index1.php file to list all students in PDF , click the mark column to display the mark sheet of individual student ( index-pdf-mark.php is included inside the zip file.)

Check the readme.txt file for more detail.

Adding QR code to PDF document.

We can generate QR code by using the student id and the same can be inserted to the generated PDF document.
We will generate one QR code image by using Google chart API and same image we will insert to our document.

This is not yet deprecated and if you find it not working then let us know, we will change to other sources.
https://developers.google.com/chart/infographics/docs/overview

Here is the code to create the image ( QR code ) and add the same to our document.

$QR="https://chart.googleapis.com/chart?chs=50x50&cht=qr&chl=$row->id";
$pdf->Image($QR,150,5,50,50,'PNG');
