<?php

public function generatePDFFile() {

$base_url=base_url();

$data = array();

$htmlContent='';

$data['getInfo'] = 'My PDF Data';

$htmlContent = $this->load->view('back/admin/pdf_file', $data, TRUE);

You can not use the base_url() when you uploaded any file or generated any file. Here you need to remove base_url() from the file path, or “FCPATH” to replace base_url().

For Example:

1

2

3

4

5

<?php

(FCPATH.'assets/generate_pdf/'.$createPDFFile, $htmlContent);

?>

Follow this example code:

11

<?php

public function generatePDFFile() {

$base_url=base_url();

$data = array();

$htmlContent='';

$data['getInfo'] = 'My PDF Data';

$htmlContent = $this->load->view('back/admin/pdf_file', $data, TRUE);

$createPDFFile = time().'.pdf';

return $this->createPDF(FCPATH.'assets/generate_pdf/'.$createPDFFile, $htmlContent);

}

?>
