Question

是的我知道我正在使用CodeIgniter Lol

Zend条形码阅读器很好但我想将渲染的条形码保存在变量中，所以只有当我在视图中调用变量时（例如echo $ myvar）才会显示条形码

我的代码

    public function find_rma_authorization() {


        // get the posted term
        $rmaNumber = $this->input->post('con_rma_number');

        // use the model
        $data['results'] = $this->search_model->get_rma_authorization_data($rmaNumber);
        $data['barcode'] = $this->set_barcode($rmaNumber);


        $this->load->view('templates/header');
        $this->load->view('posts/rma_request_window', $data);
        $this->load->view('templates/footer');

    }

    private function set_barcode($code)
    {
        //load library
        $this->load->library('zend');
        //load in folder Zend
        $this->zend->load('Zend/Barcode');
        //generate barcode
        Zend_Barcode::render('code128', 'image', array('text'=>$code), array());

    }

Answer 1

~~您需要从函数中返回条形码：~~

return Zend_Barcode::render('code128', 'image', array('text'=>$code), array());

抱歉，我误解了你的问题。你可以试试这个：

控制器

//load library
$this->load->library('zend');
//load in folder Zend
$this->zend->load('Zend/Barcode');
//create barcode object
$barcode = Zend_Barcode::factory('code128', 'image', $barcodeOptions, $rendererOptions);
$data['barcode'] = $barcode;
$this->load->view('posts/rma_request_window', $data);

查看

// render
$barcode->render();

Answer 2

尝试在视图上使用此代码

<img src="<?php echo site_url(); ?>/controller_name/set_barcode/<?php echo $rmaNumber; ?>">

将呈现的Zend条形码保存在变量CodeIgniter中
