我正在使用FPDF创建pdf .Pdf产生完美,pdf也可通过电子邮件发送.但我也想发送正文消息.我尝试过身体信息.示例精细文本消息This is text message from shohag但只有pdf附件可用且正文为空.这是我的代码.

function send_pdf_to_user(){
    if($_REQUEST['action'] == 'pdf_invoice' ){
        require('html2pdf.php');
        $pdf=new PDF_HTML();
        $pdf->SetFont('Arial','',11);
        $pdf->AddPage();

        $text = get_html_message($_REQUEST['eventid'], $_REQUEST['userid']);
        if(ini_get('magic_quotes_gpc')=='1')
        $text=stripslashes($text);
        $pdf->WriteHTML($text);

        //documentation for Output method here: http://www.fpdf.org/en/doc/output.htm
        $attach_pdf_multipart = chunk_split( base64_encode( $pdf->Output( '', 'S' ) ) );


        //define the receiver of the email 
        $to = 'monirulmask@gmail.com';

        //define the subject of the email 
        $subject = 'Test Invoice'; 
        //create a boundary string. It must be unique 
        //so we use the MD5 algorithm to generate …

我正在尝试对LINQ执行这个简单的SQL查询.但它给我错误.

这是需要转换为LINQ的SQL查询

 DECLARE @groupID int
 SET @groupID = 2
 SELECT * 
    FROM dbo.Person p
    LEFT JOIN dbo.PersonGroup pg ON ( p.PersonID = pg.PersonID AND pg.GroupID = @groupID)

忽略@groupID.它将作为LINQ查询的函数参数提供.

这是我试过的LINQ查询.

from p in Person
 join pg in PersonGroup on new { p.PersonID, groupID } equals new { pg.PersonID, pg.GroupID } into t
 from rt in t.DefaultIfEmpty()

其中groupID作为函数参数提供.GroupID和PersonID都是int.但它给了我以下错误,

Error   2   The type of one of the expressions in the join clause is incorrect.  Type inference failed in the call to 'GroupJoin'.

很少的帮助将不胜感激.
