将生成的二维码图像保存到路径中

Question

我从数据库动态生成二维码，我需要将它们存储在指定的路径中。当我生成二维码并单独保存时，但现在批量生成它们时，我需要将它们存储在我喜欢的路径中。我怎样才能做到这一点？

这是我的功能

function print_qr1(){
$qr_code_config = array();
$qr_code_config['cacheable']    = $this->config->item('cacheable');
$qr_code_config['cachedir']     = $this->config->item('cachedir');
$qr_code_config['imagedir']     = $this->config->item('imagedir');
$qr_code_config['errorlog']     = $this->config->item('errorlog');
$qr_code_config['ciqrcodelib']  = $this->config->item('ciqrcodelib');
$qr_code_config['quality']      = $this->config->item('quality');
$qr_code_config['size']         = $this->config->item('size');
$qr_code_config['black']        = $this->config->item('black');
$qr_code_config['white']        = $this->config->item('white');
$this->ci_qr_code->initialize($qr_code_config);
// get full name and user details
$user_details['doctordata'] = $this->user->get_users();
foreach ($user_details['doctordata'] as $value) {
$image_name = $value->DOCTORCODE . ".png";
$codeContents = "www.36d.co.in/qr_code=";
$codeContents .= $value->DOCTORCODE;
$codeContents .= "n";
$params['data'] = $codeContents;
$params['level'] = 'H';
$params['size'] = 10;
$params['savename'] = FCPATH . $qr_code_config['imagedir'] . $image_name;
$this->ci_qr_code->generate($params);
$this->data['qr_code_image_url'] = base_url() . $qr_code_config['imagedir'] . $image_name;
// save image path in tree table
$this->user->change_userqr($value->DOCTORCODE);
// then redirect to see image link
$file = $params['savename'];
function do_upload($file){
$config['upload_path']          = './uploads/qrcode/';
$config['allowed_types']        = 'png';
$config['max_size']             = 0;
$config['max_width']            = 0;
$config['max_height']           = 0;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload($file))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}

希望这将帮助您：

你的print_qr1方法应该是这样的：

function print_qr1()
{
$qr_code_config = array();
$qr_code_config['cacheable']    = $this->config->item('cacheable');
$qr_code_config['cachedir']     = $this->config->item('cachedir');
$qr_code_config['imagedir']     = $this->config->item('imagedir');
$qr_code_config['errorlog']     = $this->config->item('errorlog');
$qr_code_config['ciqrcodelib']  = $this->config->item('ciqrcodelib');
$qr_code_config['quality']      = $this->config->item('quality');
$qr_code_config['size']         = $this->config->item('size');
$qr_code_config['black']        = $this->config->item('black');
$qr_code_config['white']        = $this->config->item('white');
$this->ci_qr_code->initialize($qr_code_config);
// get full name and user details
$user_details['doctordata'] = $this->user->get_users();
foreach ($user_details['doctordata'] as $value) {
$image_name = $value->DOCTORCODE . ".png";
$codeContents = "www.36d.co.in/qr_code=";
$codeContents .= $value->DOCTORCODE;
$codeContents .= "n";
$params['data'] = $codeContents;
$params['level'] = 'H';
$params['size'] = 10;
$params['savename'] = FCPATH . $qr_code_config['imagedir'] . $image_name;
$this->ci_qr_code->generate($params);
$this->data['qr_code_image_url'] = base_url().$qr_code_config['imagedir']. $image_name;
// save image path in tree table
$this->user->change_userqr($value->DOCTORCODE);
// then redirect to see image link
$file = $params['savename'];
my_upload($file);
}
}

这是您的my_upload方法

function my_upload($file)
{
$config['upload_path']          = './uploads/qrcode/';
$config['allowed_types']        = 'png';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload($file))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
