Generating a PDF using CodeIgniter - php

Question

I am using dompdf to create a pdf file out of an html file that gets created on-the-fly for the sole purpose of it serving as input for the pdf generator, however I am having trouble doing this, I implemented the code in this thread and everything works fine (I could output a simple pdf) however when I try to give it a more specific url I get this error:
An Error Was Encountered Unable to
load the requested file
here's the code that has the problem:
function printPDF(){
//write_file() usa un helper (file)
$this->load->library('table');
$this->load->plugin('to_pdf');
// page info here, db calls, etc.
$query = $this->db->get('producto');
$data['table'] = $this->table->generate($query);
$path_url = base_url().'print/existencias.html';
write_file($path_url, $data['table']);
$html = $this->load->view($path_url, 'consulta', true);
pdf_create($html, 'consulta');
}

Answer 1

Not sure about the exact problem, but please check this:
1) as stated in CI's manual, load->view's second parameter should be an associative array or an objet, translated to vars via extract. That may generate some problem generating $html.
2) try making $path_url relative to application/views directory, as read in CI's manual.

Answer 2

you should use tcpdf to create a pdf.
//create controller for example :
public function create_pdf()
{
$this->load->library("Pdf");
$data['results'] = // your data
$this->load->view('pdfview',$data);
}
//pdfview is the page having tcpdf code and your pdf code.

You can try it like this
public function export_pdf() {
$filename = 'FILENAME.pdf';
header("Content-Description: Advertise Report");
header("Content-Disposition: attachment; filename=$filename");
header("Content-Type: application/pdf; ");
$file = fopen('php://output', 'w');
$header = array("Question", "Answer", "Name", "Email", "Phone", "Date");
fputpdf($file, $header);
fputpdf($file, 'YOUR DATA');
fclose($file);
exit;
}
