Question

我正在尝试使用php脚本生成水晶报告。该脚本似乎在ReadRecords（）之后挂起;日志文件中不会生成任何错误消息。我做错了吗？

$my_report = "C:\\inetpub\\wwwroot\\mamobile\\reports\\invoice.rpt";
$my_pdf = "C:\\inetpub\\wwwroot\\mamobile\\reports\\test.pdf";

$ObjectFactory = new COM("CrystalReports115.ObjectFactory.1");

$crapp = $ObjectFactory->CreateObject("CrystalDesignRuntime.Application.11");

$creport = $crapp->OpenReport($my_report, 1);

$creport->EnableParameterPrompting = 0;

$creport->DiscardSavedData;
$creport->ReadRecords();

$creport->FormulaSyntax = 0;
$creport->RecordSelectionFormula = "{invoice.invoiceid} = 20070128114815";

$creport->ExportOptions->DiskFileName = $my_pdf;
$creport->ExportOptions->FormatType = 31;
$creport->ExportOptions->DestinationType=1;
$creport->Export(false);

$creport = null;
$crapp = null;
$ObjectFactory = null;

此代码的类似版本适用于其他报告。

$my_report = "C:\\inetpub\\wwwroot\\mamobile\\reports\\" . $name;
$my_pdf = "C:\\inetpub\\wwwroot\\mamobile\\reports\\test.pdf";

$ObjectFactory = new COM("CrystalReports115.ObjectFactory.1");

$crapp = $ObjectFactory->CreateObject("CrystalDesignRuntime.Application.11");

$creport = $crapp->OpenReport($my_report, 1);

$creport->EnableParameterPrompting = 0;

$creport->DiscardSavedData;
$creport->ReadRecords();

$creport->ExportOptions->DiskFileName = $my_pdf;
$creport->ExportOptions->FormatType = 31;
$creport->ExportOptions->DestinationType=1;
$creport->Export(false);

$creport = null;
$crapp = null;
$ObjectFactory = null;

Answer 1

这就解决了我的问题。

$my_report = "C:\\inetpub\\wwwroot\\mamobile\\reports\\invoice.rpt";
$my_pdf = "C:\\inetpub\\wwwroot\\mamobile\\reports\\test.pdf";

$ObjectFactory = new COM("CrystalReports115.ObjectFactory.1");

$crapp = $ObjectFactory->CreateObject("CrystalRuntime.Application.11");

$creport = $crapp->OpenReport($my_report, 1);

$creport->EnableParameterPrompting = 0;
$creport->FormulaSyntax = 0;


$creport->DiscardSavedData();
$creport->RecordSelectionFormula = "{invoice.invoiceid} = 20070128114815";
$creport->ReadRecords();

$creport->ExportOptions->DiskFileName = $my_pdf;
$creport->ExportOptions->FormatType = 31;
$creport->ExportOptions->DestinationType=1;
$creport->Export(false);

$creport = null;
$crapp = null;
$ObjectFactory = null;

Answer 2

您应该使用DIRECTORY_SEPARATOR代替\\
您正在调用$creport->DiscardSavedData - 如果这是一个变量，它什么都不做。如果是函数调用，则应为$creport->DiscardSavedData()。

在脚本开头尝试这些设置：

ini_set('error_reporting', -1); # displays all errors
ini_set('display_errors', 1);   # reports errors to browser/console
