如何将 "Prince" 库添加到 CodeIgniter？

Question

我想使用这个库：http://www.princexml.com/ 它可以帮助我从 HTML/XML 文件创建 PDF 文件。

我从这里下载了 PHP zip 文件：http://www.princexml.com/download/wrappers/ 并将其添加到 codeigniter 目录中我的 "libraries" 文件夹中。据我所知，我只需要 include/call 图书馆并定期使用它的功能。 https://ellislab.com/codeigniter/user-guide/general/creating_libraries.html
我正在使用 WAMP (Windows)，所以我在找到 prince.exe 的地方为 C:\Program Files (x86)\Prince\engine\bin 创建了一个别名，并将其命名为 "prince" (http://localhost/prince)。

我的控制器上有这个：

public function banana(){

    $this->load->library('prince');

    $prince = new Prince('http://localhost/prince/prince.exe');


    $xmlPath = 'http://localhost/temp/test.html'; 

    $this->prince->convert_file_to_passthru($xmlPath);


}

我遇到了这些错误：

A PHP Error was encountered

Severity: Warning

这是我第一次运行来自 CodeIgniter 的外部库，我不确定该怎么做，codeigniter 文档没有提及太多信息。

创建 ALIAS 无效，所以我认为这就是它无法识别 exePath 变量的原因。

如何使用所有 "Prince" 库并使其在 CodeIgniter 上运行？

Answer 1

你应该试试这个：

public function banana(){
    // it should be a local path instead of URL
    $exe_path = 'c:\some_folder\prince\prince.exe';
    // you can add parameter for the constructor call
    $this->load->library('prince', $exe_path);
    // it also should be a local path where the folder should be writable by apache
    $xmlPath = 'c:\some_folder\temp\test.html';

    $this->prince->convert_file_to_passthru($xmlPath);
}

Answer 2

要将 "Prince" 用作 CI 上的库：

将 Prince.php 添加到库文件夹 (/application/library/Prince.php) 并确保文件名首字母大写。

要将变量传递给库，必须使用数组而不是简单的字符串来完成。 $exePath = array('exePath' => 'C:\Program Files (x86)\Prince\engine\bin\prince.exe');

public function banana(){ // it should be a local path instead of URL $exePath = array('exePath' => 'C:\Program Files (x86)\Prince\engine\bin\prince.exe');

// you can add parameter for the constructor call
$this->load->library('prince', $exePath);
// it also should be a local path where the folder should be writable by apache
$xmlPath = 'C:\wamp\www\tools\files\banana\test.html';
$pdfPath = 'C:\wamp\www\tools\files\banana\test.pdf';
$this->prince->convert_file_to_file($xmlPath, $pdfPath);

}

构造将变量作为数组获取，而不是像它应该的那样作为字符串获取！所以我稍微编辑了 __construct：

public function __construct($exePathArr) { // var_dump($exePathArr); $exePath = "banana"; // just to make sure that this var is a string :P // var_dump($exePath); $exePath = $exePathArr['exePath']; // var_dump($exePath); $this->exePath = $exePath; $this->styleSheets = ''; $this->scripts = ''; ... ....... ..........

这是在 "Prince" 网站中打开的 post： http://www.princexml.com/forum/topic/3318/princexml-and-codeigniter-how-to-add-the-library?p=1#16234

希望这对也有需要的人有所帮助。

我在 WAMP 和 UBUNTU 服务器上测试了这个。
