Hello guys
I have upgraded my CodeIgniter 2.1.3 project to CodeIgniter 3.1.4.
I am facing problem in generating pdf files in the new version whereas I could do it in CodeIgniter 2.1.3. Now only a blank page comes up.
The changes I have made are as follows:
Create a folder libraries under application folder and put tcpdf folder under it.
Create a file Pdf.php in the same level as tcpdf folder and its contents are as follws:
Code: <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
require_once dirname(__FILE__) . '/tcpdf/tcpdf.php';
class Pdf extends TCPDF
{
function __construct()
{
parent::__construct();
}
}
Then in the controller Project, I am calling the function report_pdf_excel () as below:
Code: <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Project extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url', 'array'));
$this->load->library('form_validation');
$this->load->model('project_model', 'project');
$this->load->library('Pdf');
}
public function report_pdf_excel()
{
$this->form_validation->set_error_delimiters('<li class="breadcrumb">', '</li>');
if ($this->form_validation->run() == FALSE) {
} else {
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 001');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
// set default header data
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 001', PDF_HEADER_STRING, array(0,64,255), array(0,64,128));
$pdf->setFooterData(array(0,64,0), array(0,64,128));
// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
// set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
// set some language-dependent strings (optional)
if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
require_once(dirname(__FILE__).'/lang/eng.php');
$pdf->setLanguageArray($l);
}
// ---------------------------------------------------------
// set default font subsetting mode
$pdf->setFontSubsetting(true);
$pdf->SetFont('dejavusans', '', 14, '', true);
// Add a page
// This method has several options, check the source code documentation for more information.
$pdf->AddPage();
// set text shadow effect
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));
// Set some content to print
$html = <<<EOD
<h1>Welcome to <a href="http://www.tcpdf.org" style="text-decoration:none;background-color:#CC0000;color:black;"> <span style="color:black;">TC</span><span style="color:white;">PDF</span> </a>!</h1>
<i>This is the first example of TCPDF library.</i>
<p>This text is printed using the <i>writeHTMLCell()</i> method but you can also use: <i>Multicell(), writeHTML(), Write(), Cell() and Text()</i>.</p>
<p>Please check the source code documentation and other examples for further information.</p>
<p style="color:#CC0000;">TO IMPROVE AND EXPAND TCPDF I NEED YOUR SUPPORT, PLEASE <a href="http://sourceforge.net/donate/index.php?group_id=128076">MAKE A DONATION!</a></p>
EOD;
// Print text using writeHTMLCell()
$pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);
ob_end_clean();
//Close and output PDF document
$pdf->Output('status_report.pdf', 'I');
}
}
}
I am only getting a blank page where as in CodeIgniter 2.13 I was able to generate the pdf.
Any guidance will be very much appreciated.
Regards,

Thanks for the reply.
Removing the line didn't make any difference. I had put it there because without it the pdf didn't get generated in Codeigniter 2.1.3.
Now with or without it the pdf library has stopped working. It doesn't throw any error also.
I am at my wit's end.

Additional remarks, options: You can activate Composer (see the manual) and then install TCPDF by using it.
composer.json
Code: {
"config": {
"preferred-install": "dist"
},
"require": {
"tecnickcom/tcpdf": "^6.2.12"
}
}
Since Composer provides it own autoloader, your library Pdf and the line $this->load->library('Pdf'); would not be needed anymore.
After that test the pdf generation with some simple static data (from the given examples), without using a form and form validation. Then modify and test your application specific code.
