I get a blank page when I generate a PDF using tcpdf in some cases. If the number of pages is less than 17 it will generate correctly the file. If it's greater a blank pdf page will be generated. This is my code
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE, PDF_HEADER_STRING);
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(0,5,0,0);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
$pdf->setPrintHeader(FALSE);
$pdf->AddPage('L', 'A4');
$pdf->SetFont('arialuni','',10);
$pdf->writeHTML($Content, true, 0, true, true);
$pdf->lastPage();
$pdf->Output('example.pdf', 'I');
You need to allow maximum execution time for PHP script.
Set the maximum execution time in your PHP.ini. Link
If it doesn't work, add set_time_limit(0); on top of your PHP Script.

guys i use TCPDF library for my php server and i want to create a label with width:57mm and height:32mm
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$pdf->SetPrintHeader(false);
$pdf->SetPrintFooter(false);
$pdf->AddPage('L', array(57,32));
$pdf->SetFont('dejavusans');
$html ="
<table class='domi'>
<tbody >";
for($i=0; $i<$rows; $i++){
$style=' style="font-size:'.$fontsize[0][$i].'px"';
if($bold[0][$i]===0){
$html2a[$i] = "<tr><td".$style.">".$content_line[$i]."</td></tr>";
} else {
$html2a[$i] = "<tr><td".$style."><b>".$content_line[$i]."</b></td></tr>";
}
$html2b .= $html2a[$i];//$pdf->GetStringWidth($html2a[$i])." ";
}
$html3 = "</tbody>
</table>";
$pdf->writeHTMLCell($w=55, $h=2, $x='1', $y='1', $html.$html2b.$html3, $border=1, $ln=1, $fill=0, $reseth=false, $align='C', $autopadding=true);
$pdf->Output($_SERVER['DOCUMENT_ROOT'] . 'Site/labels/label'.$id.'.pdf', 'FI');
1st of all it prints the contents fine from the database in A4 size etc but all i want is to create and save the pdf document in the label size width:57mm and height:32mm!!! https://i.stack.imgur.com/kQ8Be.png
as you see, I've marked with 1-5 numbers the actual data and the rest are marked with questionmarks!! I dont understand why of course.
2nd when i change the line $pdf->AddPage('L', array(57,32)); to $pdf->AddPage('L', array(57,57)); the label is created but i have an empty space in the bottom-right corner + it doesnt have the 32x57 size!!! https://i.stack.imgur.com/XgEWU.png
thanks in advance!!!
it seems that i had missconfigured my TCPDF library...
the simple solution that i came up was to put this line
$pdf->SetAutoPageBreak(true, 0);
after this
$pdf->SetFont('dejavusans');
and the result was perfect!!!
https://i.stack.imgur.com/hGwyR.png <-perfectly configured label
https://i.stack.imgur.com/khs9v.png <-wrongly configured label
but in my case it perfect for the job!!! all i want is to preview the result before saving (i mean saving the wrong configuration and then update the base until the configuration is good!!)
I want to add an image in header using TCPDF in my Magento store.
I am doing this:
$tcpdf = new TCPDF_TCPDF();
$img = file_get_contents(Mage::getBaseDir('media') . '/dhl/logo.jpg');
$PDF_HEADER_LOGO = $tcpdf->Image('#' . $img);//any image file. check correct path.
$PDF_HEADER_LOGO_WIDTH = "20";
$PDF_HEADER_TITLE = "This is my Title";
$PDF_HEADER_STRING = "This is Header Part";
$tcpdf->SetHeaderData($PDF_HEADER_LOGO, $PDF_HEADER_LOGO_WIDTH, $PDF_HEADER_TITLE, $PDF_HEADER_STRING);
$tcpdf->Output('report_per_route_'.time().'.pdf', 'I');
What steps I have to follow if I want to add my store name (left corner) and logo (right corner)?
If you are trying to generate the pdf using the WriteHTML() here is a little trick to add image without use of image() function.
Simply use the HTML <img> as below,
$image_path = 'path/to/image';
$print = '<p>some text here...</p>';
$print .= '<img src=" '. $image_path .' ">';
and you can use inline css to apply height, width etc.
TCPDF is tricky about inserting images as HTML. It implements few hacks to tell what is being loaded:
inserting image with src attribute as absolute path - must have star * prefix:
<img src="*/var/www/my-image.png">
inserting image with src attribute as relative path - both examples are treated as relative paths:
<img src="/var/www/my-image.png">
<img src="var/www/my-image.png">
Note, that relative paths are calculated differently on linux and windows - what works correctly on windows may not work well on linux. That is caused by checking first character in a path string as a forward slash /, which is considered a linux root and the path will be recalculated - relative path will append to a global variable DOCUMENT_ROOT.
Loading base-64 encoded string - must have # prefix in src attribute:
<img src="#iVBORw0KGgoAAggfd0000555....">
<img src="#'.base64_encode(file_get_contents($path)).'" width=50 height=35>
This is safe bet if you want to avoid issues with calculating correct path, but adds extra I/O overhead, because TCPDF will attempt to store supplied data as temporary image file in order to determine image width & height.
Ok. First of all $PDF_HEADER_LOGO is suppose to be an image file name, not image data - as in default implementation of Header() function. There is, however, one important thing to remember, exact location depends on K_PATH_IMAGES constant, which should contain path to images folder. If its defined before including TCPDF library its ok, if not TCPDF checks some default paths and first existing is used as images directory. Those directories are:
./examples/images/
./images/
/usr/share/doc/php-tcpdf/examples/images/
/usr/share/doc/tcpdf/examples/images/
/usr/share/doc/php/tcpdf/examples/images/
/var/www/tcpdf/images/
/var/www/html/tcpdf/images/
/usr/local/apache2/htdocs/tcpdf/images/
K_PATH_MAIN (which is root tcpdf folder)
So either define constant before, or put your file to one of above directories, and then pass only file name as first argument to SetHeaderData and it should work.
To have something similar for Footer you need to extend base TCPDF_TCPDF class and overwrite its Footer method.
Example:
class MYPDF extends TCPDF_TCPDF {
// Page footer
public function Footer() {
// Position at 15 mm from bottom
$this->SetY(-15);
// Set font
$this->SetFont('helvetica', 'I', 8);
// Page number
$this->Cell(0, 10, 'COMPANY NAME', 0, false, 'C', 0, '', 0, false, 'T', 'M');
$this->Image('/path/to/image.jpg', 500)
}
}
You'll probably need to work out exact coordinates. Especially in Image it depends on your dimensions, you can add another parameter to Image function being y coordinate, and two others - width and height of image.
And most importantly I recommend checking great examples section on TCPDF page:
http://www.tcpdf.org/examples.php
I am writing a script that generates Chinese character worksheets (so students can generate and practice writing)
The script is passed a 15 character string from a form in index.php.
The string is then exploded into an array of 15 elements (each a Chinese character).
The problem arises when I want to use the Write() function to populate the file with these characters, I've used the input to pick appropiate images without any problems but now it's the encoding of the fonts that gives me a hard time.
PS. I need to use a cursive/handwritten font as default 'print' fonts are not suitable for handwriting practice.
Ideally I would like to use HDZB_36.TTF or Sharp Regular Script Font
See the code below as well as images of errors I get with some different fonts.
<?php
header('Content-Type: text/html; charset=utf-8');
// linking TCPDF and FPDI libraries
require_once('tcpdf/tcpdf.php');
require_once('fpdi/fpdi.php');
// First retrieve a 15 chinese charcters long string from POST form in index.php
$hanzi = $_POST["hanzi"];
// Explode the hanzi into a 15 items array
function mb_str_split($hanzi){
return preg_split('/(?<!^)(?!$)/u', $hanzi);
}
$charlist = mb_str_split($hanzi);
// Define starting y positions of each line of the grid
$yPos1 = 10.71;
$yPos2 = 17.94;
// Creating new page with PDF as a background
$pdf = new FPDI();
$background = $pdf->setSourceFile('images/worksheet_template1.pdf');
$tplIdx = $pdf->importPage(1);
$pdf->AddPage();
$pdf->useTemplate($tplIdx, 0, 0, 210, 285, false);
/*
This is where the problem starts, I can manage to display latin characters using helvetica
but when I use any of the chinese fonts (usually encoded as GB2312 or BIG5) it fails.
With some larger (ex. stsong) fonts I get a browser error saying: No data received ERR_EMPTY_RESPONSE (Image 1)
With font 'htst3' the characters appeared upside down and were full of artifacts (Image 2).
With font HDZB_36 the characters were not rendered at all.
Other fonts will result in all of the chars displayed as '?' (Image 3)
*/
$fontname = TCPDF_FONTS::addTTFfont('ukai.ttf', 'TrueTypeUnicode', '', 64);
$pdf->SetFont('ukai','', 20);
for ($i = 0; $i <= 14; $i++){
// Generating path of the stroke order image (that works fine)
$sImgPath = "images/x-s.png";
$sImgPath = str_ireplace('x', $charlist[$i], $sImgPath);
// Stroke order image
$pdf->Image($sImgPath, '14', $yPos1, '','5');
// Here we will populate grid of the worksheet with chinese characters as TEXT
$pdf->SetXY(12.4,$yPos2);
$pdf->SetTextColor(0, 0, 0);
$pdf->Write(0, $charlist[$i], '', false);
$pdf->SetXY(24.2,$yPos2);
$pdf->SetTextColor(192,192,192);
$pdf->Write(0, $charlist[$i], '', false);
// Increase the y pos values so the next run of for() will draw in another line
$yPos1 = $yPos1+17.83;
$yPos2 = $yPos2+17.78;
}
ob_clean();
$pdf->Output('worksheet.pdf', 'I');
?>
Just a suggestion:
The file you generate worksheet.pdfshould perhaps have the same encoding as your letters.
The PDF should have the appropriate encoding, see: https://stackoverflow.com/a/10656899/1933185
I have a PDF with fillable forms. I can successfully fill the forms and save the new PDF to my server no problem, but I cannot place an image on the PDF. When I remove the Image(....) line the script works great. When I add it back it I get the error.
I think it's trying to look for the method in the wrong file, originally I only included fpdm..php but I tried adding back fpdf.php and it did not help. Not sure what I'm doing wrong.
Error:
Fatal error: Call to undefined method FPDM::Image() in /home/.../formPDF.php on line 113
Code:
require('../forms/pdf/fpdf.php');
require('../forms/pdf/fpdm.php');
$pdf = new FPDM($formPDFLocation);
$pdf->Image('images/sig_37-1405313221.png', 100, 20);
$pdf->Load($fields, false); // second parameter: false if field values are in ISO-8859-1, true if UTF-8
$pdf->Merge();
$filename= "../forms/generated/" . $ffID;
$pdf->Output($filename.'.pdf','I');
FPDM is not really related to FPDF but simply a script of a FPDF user. You cannot use FPDF methods on an FPDM instance.
If you search for an all in one solution for such task you may take a look at the SetaPDF-FormFiller component (not free!).
I was able to save the PDF to my server and then add the image but lost the form contents. Code for anyone that is interested in this half solution:
Code for adding image:
<?php
require_once('fpdf.php');
require_once('fpdi.php');
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile("16.pdf");
$tplIdx = $pdf->importPage(1);
$pdf->useTemplate($tplIdx, 10, 10, 100);
$pdf->Image('car.jpg',20,100);
$pdf->Output();
?>
I'm trying to find out if the Fine Uploader can limit the total amount of images allowed. So lets say I'd like to limit the images to 5 and a user drag and drops or selects 6 images it will prompt the user saying that can't be done due to only allowing a maximum of 5 images.
I've been looking at the documentation but I might have missed it.
Change the validation.itemLimit option to match the max number of files you want to add, change the validation.acceptFiles and validation.allowedExtensions to match only image files (validation docs)
var uploader = new qq.FineUploader({
/* ... */
validation: {
itemLimit: 5,
acceptFiles: 'image/*',
allowedExtensions: ['.jpe', '.jpg', '.jpeg', '.gif', '.png', '.bmp', '.ico', '.svg', '.svgz', '.tif', '.tiff', '.ai', '.drw', '.pct', '.psp', '.xcf', '.psd', '.raw']
}
});
Note: If you want a custom error message, then change text of the messages.tooManyItemsError option to equal the specific error message you want (error handling docs).
You can also add code to the onError callback to customize how and when your message is shown (events docs) or do some other operation.
