Create your own helper file to generate PDF in PHP(Codeigniter)

           

 As of late, we have talked about "How to produce PDF utilizing PHP".  Today I am going to compose custom helper file to generate PDF. Did you ever thought of creating your own custom helper file to generate PDF in PHP(Codeigniter)?

Below custom helper script will generate a PDF file. You can export grid data into a PDF document.

I am going to create a single helper file to export any grid data into PDF. All you have to do is,  call my helper file and pass your data into the function, That’s all done. This script will generate PDF page.

Creating helper will help you to reuse the code and you don’t have to write much lines of codes. So let’s follow few steps as below.

 

Step 1:

Download files from dom-pdf and m-pdf and extracts it into your helper folder, ie: /system/helpers/dompdf (or mpdf ).

Step 2:

Now create your own helper and name it pdfexport_helper.php and paste the below lines of code. If you are using mpdf then use below code.

/*
* Subject          : Export pdf using mpdf
* Author           : Sanjoy Dey
* @Created Date    : 10-02-2012
* Version          : CodeIgniter_2.0.3
*
*/

if ( ! function_exists('exportMeAsMPDF')) {

    function exportAsMPdf($htmView, $fileName) 
    {

        $CI =& get_instance();
        $CI->load->library('mpdf51/mpdf');
        // $CI->mpdf=new mPDF('c','A4','','',32,25,27,25,16,13);
        $CI->mpdf->AliasNbPages('[pagetotal]');
        $CI->mpdf->SetHTMLHeader('{PAGENO}/{nb}', '1',true);
        $CI->mpdf->SetDisplayMode('fullpage');
        $CI->mpdf->pagenumPrefix = 'Page number ';
        $CI->mpdf->pagenumSuffix = ' - ';
        $CII->mpdf->nbpgPrefix = ' out of ';
        $CI->mpdf->nbpgSuffix = ' pages';
        $CI->mpdf = new mPDF('', 'A4', 0, '', 12, 12, 10, 10, 5, 5);
        $style = base_url().'/source/template/css/stylesheet.css';
        $stylesheet = file_get_contents( $style);
        $CI->mpdf->WriteHTML($stylesheet,1);                       
        $CI->mpdf->WriteHTML($htmView,2);                       
        $CI->mpdf->Output('mpdf.pdf','I');
     }
  }

If you are using dompdf then use below code.

 
  
/*
* Subject          : Export pdf using dompdf
* Author           : Sanjay
* Version          : CodeIgniter_2.0.3
*/

if ( ! function_exists('exportMeAsDOMPDF')) {

     function exportAsDomPdf($htmView, $fileName) 
     {

         $CI =& get_instance();
         $CI->load->helper(array('dompdf', 'file'));
         $CI->load->helper('file');
         $pdfName = $fileName;
         $pdfData = pdf_create($htmView, $pdfName);
         write_file('Progress Repost', $pdfData);   
     }
}

?>
 
 

Step 3:

Open your controller page and inside your function write below code.

 #Export Function goes here#
 /*This Function is used for Exporting Pdf
  * Author : Sanjay
  */

  $this->load->helper(‘pdfexport_helper.php’);
  $urlId  = $this->uri->segment('3');

    if($urlId == "export") {

       $data['pageTitle'] = "Annual Report";
       $data['htmView'] = $this->load->view('annualreport_view',$data,TRUE);
       $templateView  = $this->load->view('../template_export',$data,TRUE);
       exportAsMPdf($templateView,$data['filename']);     
          OR          
       exportAsDomPdf($htmView,$fileName)                                                                 
    }

/* Export Pdf END here */

Step 4:

That’s all you have done all steps. Click in export button to export to PDF and enjoy.
