I used this library for domPDF in CI https://github.com/iamfiscus/Codeigniter-DOMPDF

Code:
// controller

function send_pdf($id)

{

  $this->load->model('student_model');

  $data['student'] = $this->student_model->getStudentInfo($id);

  $html = $this->load->view('pdf/document-view', $data, true);

  $pdf = $this->generate_pdf($html);

  if($pdf)

  {

     // another function that uses the CI email library and attaches the pdf, no need to include it here - you understand that part

     $this->send_pdf_email($pdf);

  }

}

private function generate_pdf($html) {

  $this->load->helper('file');

  $this->load->helper('dompdf');

  $file_name = rand(5, 15000);

  $pdf = pdf_create($html, '', false);

  $full_path = "/path/to/upload_directory/".$file_name.".pdf";

  if(!write_file($full_path, $pdf))

    return false;

  return $full_path;

}

// view (pdf/document-view)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> 

&lt;html&gt;

&lt;head&gt;

 &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;

&lt;title&gt;&lt;?=$student->first_name?&gt; &lt;?=$student->last_name?&gt;&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<div class="container_12 header">

 <h1>Page Title</h1>

</div>

<div class="container_12 content">

 <div class="split">

  <p><span>Current Name:</span> &lt;?=$student->first_name?&gt; &lt;?=$student->last_name?&gt;</p>

 </div>

&lt;/body&gt;

&lt;/html&gt;

You need to use inline styles in the view, I removed them in my example I pasted here, so it is easier to read.

I have the private function generate_pdf to take the output send_pdf function creates, it also generates a filename for the pdf and writes it to the designated upload directory.

Hope this helps!

Hi, Happy News!!

OK, Now Id like to explain where have I done mistakes.

I have used mpdf library.

I had 2 functions in controller function reporting(), and function topdf()
In my search page after i choose the options i simply click the submit button and that passes these form values to function reporting(), and in this function i call my model, in the model queries run, ....etc and finally results returned to the same function as an array. I use this array when i load the view function and Everything works fine, i get nice reporting page.

Here is my mistake;

I put a link in this page so that when i click it i can print it out as a pdf file. However in the anchor I called another function, function topdf(). Obviously im not passing any values to this function. Thats why i cant see the variables in pdf file.

I copied all the content in the function topdf() into function reporting(), and when i click submit button i get pdf file automatically with the variables i need it.

at this moment Im happy as I understood my mistakes. Now I need to find a way to pass any values from foreach function to controller function using anchor.

Thanks for your help.

          {

            if($this->input->post('date1')){

                if($this->input->post('date2')){

          $data['reports'] = $this->blog_model2->reporting(); 

          $reports =array();    

     //below the code i have copied from function topdf()

         $html = $this->load->view('report_view2', $data, TRUE);

        $mpdf=new mPDF();

        $mpdf=new mPDF('c','A4','','',32,25,27,25,16,13);

        $mpdf->WriteHTML($html,2);

        $mpdf->WriteHTML($this->output->get_output(),2);

        $mpdf->Output('mpdf.pdf','I');

        }else{

            echo "Please enter a valid end date!";

        }

       }

       else{

            echo "Please enter a valid start date!";

        }

        } //submit

        else {

        $this->load->view('header_view');

        $this->load->view('nav_view');

        $this->load->view('report_view');

        $this->load->view('footer_view');

        } //report_view

    } //report
