TCPDF works locally, but not on-line

Question

I am working on dynamically generating a PDF using PHP * the TCPDF/FPDI classes..

While developing locally (WAMP/localhost).. things have been working fine..

now that I have uploaded things to the LIVE server.. I get nothing but a blank page on the SAME files.. with the SAME directory structure..

However, when testing on LIVE environment.. it doesnt work?

Just a blank page, no errors..etc.

here is the code Im currently using..

(I tried to add in the UTF-8 encoding in the constructor AND in the HTML output...??

code:

$live = false;

$targetID = 122;
$targetName = "Name";
$targetClient = "Client Name";

$targetAddress = "address";
$targetCity = "city";
$targetState = "State";
$targetZip = "40202";
$targetPhone = "xxx-555-1212";

$fileCreator = "xxxxx123";  
$fileAuthor = "xxx";
$fileTitle = "Title";
$fileSubject = "Ssubject";

if($live){
$targetLogo = "/path/to/logo/images/targetLogo.jpg";
$sourcePDF = "/path/to/pdf/targetPDF.pdf";
}else{
$targetLogo = "images/targetLogo.jpg";
$sourcePDF = "targetPDF.pdf";
}
$saveAsName = "DYNAMIC_BRANDING.pdf";

//client specific variables
$clientName_color = '#FF0000';
$memberName_color = '#000000';
$clientAddress_color = '#000000';


//------------------[end project vars]---------------------//



// just require TCPDF instead of FPDF
define('FPDF_FONTPATH', 'tcpdf/fonts/');
//include FPDI & TCPDF class library file(s)


if($live){
//ini_set('display_errors', '0');
//error_reporting(E_ALL | E_STRICT);
//live
require('/path/to/tcpdf.php');  
require('/path/to/fpdi.php');  //make sure to include the _TPL file in directory or it throws error.

Just a blank/empty WHITE Page each time when testing live..

what am I missing or doing wrong?

Answer 1

fixed:

couple of things to remember:

1.) dont have any blanks or spaces before you start your OUPUT

2.) make sure you have the file: fpdf_tpl.php in your FPDI directory..

(second one seemed to be my downfall at first) :)

Answer 2

I also had this problem. What fixed it for me was adding

while( ob_get_level() ) {
    ob_end_clean();
}

just above $pdf->Output. Might be related to using TCPDF on WordPress with Bluehost.

Answer 3

When you put your TCPDF Output file, Make sure you start from the root of your server. TO do so get a info.php running where your output file is located. Open the info.php and scroll almost all the way down, it will show the full path of your php file. Use the path has for the output location...

I had this issue, on my tcpdf and it solved the problem.
