Generating certificates using student photo QR code & logo with data from MySQL table using PHP GD

Adding QR code

How to add QR code to the certificate is explained in MySQL - QR Part III, the part of the code is here.

$QR=imagecreatefromstring(file_get_contents(
  "https://chart.googleapis.com/chart?chs=100x100&cht=qr&chl="
  .urlencode($row->id)));
imagecopyresampled($img_source, $QR, 475, 40 , 0, 0, 100, 100, 100,100);

Adding student photo

We will keep photos of students in one folder photos( download the zip file at the end of this page with sample photos ) . File name of the photos are same as student id like . 1.jpg, 2.jpg .... This is done to maintain unique photos against each student as there is a possibility that name of two students can be same.

$str=imagecreatefrompng("photos/".$row[id].".png");
imagecopy($img_source,$str, 60, 310 , 0, 0, 100, 100);

We created the path by using file name with directory name in above code and then by using imagecopy() the same is added at a location ( x=60, y=310 ) of the source image.

Adding Logo

If Logo is common in all certificates then it is better to add the same to main template. However to understand the process of adding images dynamically this code is used.

$str=imagecreatefrompng("logo.png");
imagecopy($img_source,$str, 280, 50 , 0, 0, 50, 50);

Above codes are kept inside the for loop used to generate certificates of all students by taking data from MySQL student table.
