问题:通过Zend库条形码在CodeIgniter中渲染条形码。
我用Google搜索,并在前两页尝试了所有教程。我堆栈溢出,发现我的问题安静了几个主题,甚至很少被标记为已回答,但没有运气。
最后我尝试了这个https://stackoverflow.com/a/15480779/1564365,但又发现了另一条错误消息。
错误:
Fatal error: Class 'Zend\Barcode\ObjectPluginManager' not found
这意味着它实际上正在加载条形码库但有错误。
旁注:ZF 2.2全新下载(今日),CI 2.1.3全新下载(今日)
答案 0 :(得分:2)
为了解决这个问题,我被迫使用ZF1。 一步一步:
Zend
文件夹中的文件夹./libraries
,将其复制到CI application/libraries
application/libraries/Zend.php
“ZF加载程序”代码如下
<?php if (!defined('BASEPATH')) {exit('No direct script access allowed');}
/**
* Zend Framework Loader
*
* Put the 'Zend' folder (unpacked from the Zend Framework package, under 'Library')
* in CI installation's 'application/libraries' folder
* You can put it elsewhere but remember to alter the script accordingly
*
* Usage:
* 1) $this->load->library('zend', 'Zend/Package/Name');
* or
* 2) $this->load->library('zend');
* then $this->zend->load('Zend/Package/Name');
*
* * the second usage is useful for autoloading the Zend Framework library
* * Zend/Package/Name does not need the '.php' at the end
*/
class CI_Zend
{
/**
* Constructor
*
* @param string $class class name
*/
function __construct($class = NULL)
{
// include path for Zend Framework
// alter it accordingly if you have put the 'Zend' folder elsewhere
ini_set('include_path',
ini_get('include_path') . PATH_SEPARATOR . APPPATH . 'libraries');
if ($class)
{
require_once (string) $class . EXT;
log_message('debug', "Zend Class $class Loaded");
}
else
{
log_message('debug', "Zend Class Initialized");
}
}
/**
* Zend Class Loader
*
* @param string $class class name
*/
function load($class)
{
require_once (string) $class . EXT;
log_message('debug', "Zend Class $class Loaded");
}
}
和控制器方法应如下
function barcode() {
$this->load->library('zend');
$this->zend->load('Zend/Barcode');
$test = Zend_Barcode::draw('ean8', 'image', array('text' => '1234565'), array());
var_dump($test);
imagejpeg($test, 'barcode.jpg', 100);
}
