Question

我正在测试运行XAMP的Windows XP上的Flexpaper插件，问题是它没有显示pdf，检查它说的php错误日志：

PHP致命错误：调用未定义的方法Config :: getConfig（）第24行的C：\ xampp \ htdocs \ PDFViewer \ php \ services \ view.php

文件夹结构是:(省略不相关的文件）

htdocs/

pdf2json_php5.php的代码片段

require_once("config.php");

在你问之前，是的，config.php确实有getConfig方法

编辑：添加了config.php

<?php date_default_timezone_set('America/New_York'); ?>
<?php
class Config{
  protected $config;

    public function __construct()
    {
        if (!defined('ROOT')) {

        if (!defined('APP_DIR')) {
            define('APP_DIR', basename(dirname(dirname(__FILE__))));
        }   

        if( PHP_OS == "WIN32" || PHP_OS == "WINNT"  )

            throw new Exception('Cant write to config ' . $fileName);

Answer 1

将view.php的代码段修改为：

$ds = DIRECTORY_SEPARATOR;
require_once("..{$ds}lib{$ds}common.php");
require_once("..{$ds}lib{$ds}pdf2swf_php5.php");
require_once("..{$ds}lib{$ds}swfrender_php5.php");
require_once("..{$ds}lib{$ds}pdf2json_php5.php");

Answer 2

在将C:/xampp/htdocs添加到php.ini中的include_path变量之后，看起来我已经使它工作了，然后只修改了require_once函数。

View.php中的

require_once部分如下所示：

require_once("PDFViewer/php/lib/common.php");
require_once("PDFViewer/php/lib/pdf2swf_php5.php");
require_once("PDFViewer/php/lib/swfrender_php5.php");
require_once("PDFViewer/php/lib/pdf2json_php5.php");

同样适用于pdf2swf_php5.php，swfrender_php5.php和pdf2json_php5.php。
