Notice: probably you should'nt use all of this in same script :)
|
||
|
|
|
||
|
|
<?phpb
|
||
|
|
|
||
|
|
//include only that one, rest required files will be included from it
|
||
|
|
include "qrlib.php"
|
||
|
|
|
||
|
|
//write code into file, Error corection lecer is lowest, L (one form: L,M,Q,H)
|
||
|
|
//each code square will be 4x4 pixels (4x zoom)
|
||
|
|
//code will have 2 code squares white boundary around
|
||
|
|
|
||
|
|
QRcode::png('PHP QR Code :)', 'test.png', 'L', 4, 2);
|
||
|
|
|
||
|
|
//same as above but outputs file directly into browser (with appr. header etc.)
|
||
|
|
//all other settings are default
|
||
|
|
//WARNING! it should be FIRST and ONLY output generated by script, otherwise
|
||
|

|
||
|
|
QRcode::png('PHP QR Code :)');
|
||
|
|
|
||
|
|
//show benchmark
|
||
|
|
QRtools::timeBenchmark();
|
||
|
|
|
||
|
|
//rebuild cache
|
||
|
|
QRtools::buildCache();
|
||
|
|
|
||
|
|
//code generated in text mode - as a binary table
|
||
|
|
//then displayed out as HTML using Unicode block building chars :)
|
||
|
|
$tab = $qr->encode('PHP QR Code :)');
|
||
|
|
QRspec::debug($tab, true);

== TCPDF INTEGRATION ==
|
||
|
|
|
||
|
|
Inside bindings/tcpdf you will find slightly modified 2dbarcodes.php.
|
||
|
|
Instal phpqrcode liblaty inside tcpdf folder, then overwrite (or merge)
|
||
|
|
2dbarcodes.php
|
||
|
|
|
||
|
|
Then use similar as example #50 from TCPDF examples:
|
||
|
|
|
||
|
|
<?php
|
||
|
|
|
||
|
|
$style = array(
|
||
|
|
'border' => true,
|
||
|
|
'padding' => 4,
|
||
|
|
'fgcolor' => array(0,0,0),
|
||
|
|
'bgcolor' => false, //array(255,255,255)
|
||
|
|
);
|
||
|
|
|
||
|
|
//code name: QR, specify error correction level after semicolon (L,M,Q,H)
|
||
|
|
$pdf->write2DBarcode('PHP QR Code :)', 'QR,L', '', '', 30, 30, $style, 'N');
