TCPDF error in production , but not in developer mode

Applications Report PDF
#1

I tried to generate PDF using TCPDF , when in developer mode, I have no trouble and result shown, but when after I upload via ftp to hosting, the error occured
[h=1][SIZE=14px]TCPDF ERROR: Some data has already been output, can’t send PDF file[/SIZE][/h] I tried several trick and nothing could fix that, strange because in developer mode no error happens.

This is my code

Event OnScriptInit

[strbrg]="";
[qtybrg]="";
[pricebrg]="";
[totprice]="";
[namacust]="";
[alamatcust]="";
[kotacust]="";
[namasales]="";
[tglinvoice]="";
[terbilang]="";

Event OnRecord

sc_include(convertnum.php);

$sqlstr="select fnamabrg, fqty,fharga from tbjualdet inner join tbbarang on tbjualdet.fidbarang=tbbarang.fidbarang where fnojual='". [globjual] ."'";

//sc_alert([globjual]);
sc_lookup(my_data, $sqlstr);

//$j=0;
if (!empty ({my_data})) {
    $datasetCount = count({my_data}); // returns count of array items of any array

    for($j=0; $j < $datasetCount; $j++)
    {
        //nama brg
        //[namabrg][$i]={my_data[$j][0]};
        [strbrg].={my_data[$j][0]};
        [strbrg].=".";

        //qty brg
        [qtybrg].={my_data[$j][1]};
        [qtybrg].=".";

        //harga barang
        [pricebrg].={my_data[$j][2]};
        [pricebrg].=".";

        //tot price
        [totprice].={my_data[$j][2]} * {my_data[$j][1]}; 
        [totprice].=".";

        [terbilang]=[terbilang]+({my_data[$j][2]} * {my_data[$j][1]});

}
    [terbilang]=terbilang([terbilang]);

}

And this code is in Layout PDF Code

Please help, this is quite urgent
Thank you

When I get this error I insert at the beginning of the code this: ob_end_clean();

I see you have this in the end.
I always do at the beginning

sc_include_lib(“tcpdf”);
sc_include_library(“prj”, “tcpdf_report_lib”, “lib_report_hf.php”, true, true);

m_get_data();

ob_end_clean();

#3

interesting, let me try it. really i never see ob_clean in the beginning, let me update after i try this .
thanks anyway

#4

Don’t ask me why or how.
Years ago, I had an identical mistake, and I corrected it.
But I remembered because I spent quite a bit of time.

#5

hi, i already tried to put ob_clean after declare tcpdf variable, but still same error

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

ob_end_clean();

$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('I-CON');
$pdf->SetTitle('Invoice Kutus');
$pdf->SetSubject('Invoice'. [globjual]);
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
//$pdf->AddPage('P','A4'); //A4 Portrait
//$pdf->AddPage('L','A4'); //A4 Landscape

I am curious, have anyone get this error or is it just me, my code really simple and it is not working…:((

#6

Thank you anyway for giving me insight, but still it won’t work, anyway…I change the report PDF invoice by not using code like before, instead I use picture as background for invoice and manually put the position X,Y for field. I still don’t know why the code works in development but not in production

#7

If you can make an export app and tables in the database I can try it on my local server and on 2 different hosting.
But I’m only 2 days in the office. Then I go on vacation for 2 weeks.

#8

okay, i will try,

#9

udah nemu error nya bang? :smiley: hehe
