PHPJasperXML 无法在 php 中打印 table 数据

Question

我正在使用 PHPJasperXML 生成和显示报告

首先我使用 jaspersoft Studio 设计报表

其次，我在 php 中使用从 jasper 生成的 jrxml 文件来显示报告。

当我在 jasper studio 中预览报告时，一切正常，但问题是当我尝试显示报告表单时 php，报告仅使用主报告中的数据生成，未生成 table 的数据。

当我从 jaspersoft studio 预览报告时，我得到了这个预期结果

但是当我尝试运行来自 PHP 的相同报告时：

它向我显示了一个没有 table 数据的列表。

jaspersoft studio 中报表设计使用的代码

显示报告的PHP代码是：

     include_once("phpjasperxml_0.9d/class/PHPJasperXML.inc.php"); // PHPJasperXML

     $class_id = (int)$_GET['class'];

     $params = array();
     $params['class_id'] = $class_id;

     $PHPJasperXML = new PHPJasperXML();
     //$PHPJasperXML->debugsql=true;
     $PHPJasperXML->arrayParameter =  $params;
     $PHPJasperXML->load_xml_file("reports/eleve_admis.jrxml"); // Name of the reports file
     $PHPJasperXML->transferDBtoArray($servername,$username, $password, $database);
     $PHPJasperXML->outpage("I"); 

?>

对于此事，我将不胜感激。或者对其他开源库使用 PHP

生成报告的任何建议

如果您使用 php 7，它将不起作用。 mysql_connect 此扩展已在 PHP 5.5.0 中弃用，并在 PHP 7.0.0 中删除欲了解更多信息，请访问 http://php.net/manual/en/function.mysql-query.php
