Yii integration Phpqrcode generate two-dimensional code with online demo address

1, first to the official website download package http://phpqrcode.sourceforge.net/

After downloading the class library provided by the official website, we only need to use phpqrcode.php to generate the QR code, of course, your PHP environment must turn on support GD2.

Phpqrcode.php provides a key PNG () method, where
The parameter $text represents the generated two-bit information text;
The parameter $outfile indicates whether the output QR code picture file, default no;
The parameter $level represents the fault tolerance, i.e., the area covered is also recognized, respectively L (qr_eclevel_l,7%), M (qr_eclevel_m,15%), Q (qr_eclevel_q,25%), H (qr_eclevel_h,30%) ；
The parameter $size indicates the generated picture size, the default is 3, and the parameter $margin indicates the spacing value of the border space around the two-dimensional code;
The parameter $saveandprint indicates whether to save the QR code and display it.

2, after downloading the extracted Phpqrcode folder into the Extensions folder, such as:

3, introduce class Phpqrcode

Yii:: $enableIncludePath = false; Yii::import (' Application.extensions.phpqrcode.phpqrcode ', 1);

Here is the complete method of generating the QR code

Public Function Actionqrcode () {$this->breadcrumbs=array_merge ($this->breadcrumbs,array (' Generate two-dimensional code ')); $qrcode _ Path= '; $file _tmp_name= '; $errors =array (); if (!empty ($_post)) {$content = Trim ($_post[' content ']);//Two-D code contents $ Contentsize= $this->getstringlength ($content), if ($contentSize >290) {$errors []= ' word is too long, no more than 150 characters! ‘;} Yii:: $enableIncludePath = false; Yii::import (' Application.extensions.phpqrcode.phpqrcode ', 1), if (Isset ($_files[' upimage ' [' tmp_name ']) && $_files[' upimage ' [' tmp_name '] && is_uploaded_file ($_files[' upimage ' [' tmp_name '])) {if ($_files[' upimage ') [' Size ']>512000) {$errors []=] The file you uploaded is too large to exceed 500K.
