Thinkphp3.2 combined with Phpqrcode to generate two-dimensional code (including logo QR code), with case

First, download the Phpqrcode and unzip it into the project Thinkphp\library\vendor directory.
Index_index.html (template can be configured by itself)

Controller: IndexController.class.php

<?phpnamespace Home\controller; UseThink\controller;classIndexcontrollerextendsController { Public functionindex () {$config=Array(            ' MaxSize ' = 3145728, ' RootPath ' and '/upload/', ' savepath ' and ', ', ' Savename ' =Array(' uniqid ', '), ' exts ' =Array(' jpg ', ' gif ', ' PNG ', ' jpeg '), ' autosub ' =true, ' subname ' =Array(' Date ', ' YMD '),        ); $upload=New\think\upload ($config);//instantiate an upload class//Upload a single file        $info=$upload->uploadone ($_files[' Test ']); if(!$info) {//Upload error message            $qrcode _path_new= './public/home/images/code '.

Then create a new function.php under Project Application/home/common

<?PHPfunctionMakecode ($qrcode _path,$content,$matrixPointSize,$matrixMarginSize,$errorCorrectionLevel,$url){        /** Parameter Details: * $qrcode _path:logo Address * $content: Need to generate two-dimensional code content * $matrixPointSize: two-dimensional code ruler          Inch size * $matrixMarginSize: Generate a two-dimensional code margin * $errorCorrectionLevel: Fault tolerance level * $url: Generated with the logo of the two-dimensional code address * */        Ob_clean (); Vendor (' Phpqrcode.phpqrcode '); $object=New\qrcode (); $qrcode _path_new= './public/home/images/code '.

In the absence of picture upload, the generation of my QR code is only a simple two-dimensional code, only when there is a logo upload, will generate a logo with the QR code.

For example, the two-dimensional code generated when there is no Logo:

The QR code that is generated when a picture is uploaded:
