$ Model = M ("member"); $ rs = $ model-> where ("tmId ". $ tmId)-> find (); // generate the QR code vendor ("phpqrcode. phpqrcode "); $ path = 'public/qrcode/'; mkdir ($ path); then qr?#path.'qrcode.png'; $ text =" http://www.xghm.com.cn/index.php/Login/reg/tmTel ". $ rs ['tmtel']; $ size = '4'; $ level = 'l'; $ padding = 2; $ logo = false; QRcode: png ($ text, $ QR, $ level, $ size, $ padding); $ this-> display ();

Remove the last $ this-> display ();. It is best to add ob_clean () before generating the image ()
I have a similar method in my code.

public function qrcode($guid) {        vendor("phpqrcode.phpqrcode");        //$data = "http://www.baidu.com";        $url="http://".$_SERVER['HTTP_HOST'].U('Urlhandle/show',array('guid'=>$guid),$domin=true);        $level = 'L';        $size = 8;        ob_clean();        \QRcode::png($url,false,$level,$size);    }

We recommend that you use the phpqrcode plug-in to generate a QR code.

public function qrcode($text='https://www.baidu.com',$level=3,$size=4){    $text=$this->$_get['text']?$this->$_get['text']:$text;    $size=$this->$_get['size']?$this->$_get['size']:$size;    $level=$this->$_get['level']?$this->$_get['level']:$level;    Vendor('phpqrcode.phpqrcode');    $object = new \QRcode();    $object->png($text, false, $level, $size, 2);}

The Landlord seems to be confused.
The first is the QR code, which requires an independent action.
Display interface, which is another action
For example:

Public function action1 () {$ this-> display ();} public function action2 (){............ QRcode: png ($ text, $ QR, $ level, $ size, $ padding);} in the template:

Then access action1.

Generate a separate method and use src of the img label to access this method,
