在CodeIgniter中加载外部库Gantii时出错

我正在尝试将其集成到我的PHP项目中：https：//github.com/bastianallgeier/gantti

我已将calendar.php和gantii.php复制到应用程序/库中。

控制器：

<?php

class summary extends CI_Controller {

  function index() {
     $this->load->library('gantti');

     $gantti = new Gantti($data, array(
  'title'      => '',
  'cellwidth'  => 25,
  'cellheight' => 35,
  'today'      => true
));

    $this->load->view('summary_view', $gantti);

  }

}

看法：

<?php

require('lib/gantti.php'); 
require('controllers/summary.php'); 

date_default_timezone_set('UTC');
setlocale(LC_ALL, 'en_US');

?>

<!DOCTYPE html>
<html>
<head>  

  <title>Summary</title>
  <meta charset="utf-8" />  

  <link href="<?php echo base_url(); ?>assets/css/gantti.css" rel="stylesheet" media="screen">
  <link href="<?php echo base_url(); ?>assets/css/metro-bootstrap.css" rel="stylesheet" media="screen">

  <script type="text/javascript" src="<?php echo base_url(); ?>assets/js/jquery-1.10.2.js"></script>

</head>

<body>

<div class="page-header">
  <h1>Summary</h1>
</div>

<?php echo $gantti ?>

</body>

</html>

但没有查看该页面，而是收到如下错误（404）：

A PHP Error was encountered

Message: Missing argument 1 for Gantti::__construct(), called in C:\xampp\htdocs\wwww\system\core\Loader.php on line 1099 and defined

梅法鲁克

load-> library`加载CI中的任何库，它将自动调用其构造函数，此库中发生的事情相同，但是您需要将至少一个参数传递给库，这就是为什么它给出错误的原因，您只能将一个参数传递给使用ci loader的库

$this->load->library('gantti',$data);

但是您不能设置第二个参数来设置该库，但是该库中的所有变量都是公共的，您可以像这样调用它们来设置它们

$this->gantti->options = array(
  'title'      => '',
  'cellwidth'  => 25,
  'cellheight' => 35,
  'today'      => true
)

完整的解决方案

$this->load->library('gantti',$data); //first load library and pass data
$this->gantti->options = array(
      'title'      => '',
      'cellwidth'  => 25,
      'cellheight' => 35,
      'today'      => true
    );
$data['gantti'] = $this->gantti->__toString();

另一个解决方案是创建一个自定义库，并使用库目录下的Gantti库复制gantti lib目录对其进行扩展

定制图书馆

<?php
    require_once APPPATH.'libraries/lib/gantti.php';

    class cigantti extends Gantti {
        //put your code here

        public function __construct() {
        }

        public function generate($data = array(), $params = array()){
            parent::__construct($data, $params);
            return $this->render();
        }
    }

    ?>

在控制器中

$this->load->library('cigantti');
$data['gantti'] = $this->cigantti->generate($data, array(
                    'title' => 'Demo',
                    'cellwidth' => 25,
                    'cellheight' => 35,
                    'today' => true
                ));
