[RESOLVED] Mulitiple PDF's with fpdf lib and CI in one controller.

[eluser]Sheldon[/eluser]
Hi,

I am using CI and FPDF with FPDFI, http://www.fpdfi.org

I have it set up and working pretty well, and have been using theses to generate a lot of PDF's in the last couple of years, but now I have a different issue,

I am trying to generate a bunch of separate PDF's inside a for loop.

The Basic's of my controller are;

Code:

<?php

    // inside my CI controller
        
        
        function monthly() {
            
//            Load PDF Library - now loading in loop to try reset buffer
//            $this->load->library('pdf');
//            Load and initialise CI Email library
            $this->load->library('email');
            $this->email->initialize(array('mailtype' => 'html'));

//            start loop - approx 15 records            
            $monthlies = $this->invoice->getMonthlies();
            if($monthlies) {
                foreach($monthlies as $monthly) {
                    
//                    Load CI/FPDF library
                    $this->load->library('pdf');
                    
//                    Create PDF ( I have remove unnesscary code that pulls data for PDF. )
//                    Make a random filename
                    $filename   = md5(time() * rand(100, 1000)) .'.pdf';
                    $this->load->view('pdf/invoice', array('filename' => $filename));
                    
//                    validate customer email and sent PDF.
                    if(valid_email($email)) {

                        $this->email->from($this->config->item('admin_mail'));
                        $this->email->to($email);
                        $this->email->reply_to($this->config->item('admin_mail'));

                        $this->email->subject('Invoice #'. $invoice_id);
                        $this->email->message($this->load->view('admin/email', array('customer' => $customer, 'invoice' => $invoice), TRUE));
                    
//                        Attach my PDF, send and clear email + all attachemnts
                        $this->email->attach($filename);
                        $this->email->send();
                        $this->email->clear(TRUE);
                    
                    }
//                end loop
                }
                
            }
            
//            finished
            redirect();
        }
    
    }

This script run's and emails each record as expected, but it is concatinating my PDF's in to one PDF, EG; 1st loop, correct single page PDF, 2nd loop, 1st page is the previous record, second is a blank PDF page ?
15th record, as the first PDF correct, and a random amount of blank pages.

My PDF View generates a single PDF fine, I have tried to reset thte PDF buffer after my output;

Code:

$this->pdf->Output($filename, 'F');
    $this->pdf->closeParsers();
    $this->pdf->Close();
    unset($this->pdf->buffer);
    $this->pdf->buffer = '';
    $this->pdf->buffer = NULL;

My CI PDF library includes the fpdfi library like so;

Code:

<?php

    if(!defined('BASEPATH')) exit('No direct script access allowed');

    require_once('fpdi.php');

    class Pdf extends fpdi {
    
        var $fontsize = 8;
    
        function Pdf() {
            parent::fpdi('P','mm','A4');
            $this->AddFont('HelveticaNeue-Light','','HelveticaNeue-Light.php');
            $this->AddFont('HelveticaNeue-Light','B','HelveticaNeue-Bold.php');
        }
    
        function Header() {
        
            $ci =& get_instance();
            $this->SetY(40);
        
        }

    
        function Footer() {
        }
    
    }

I haven't played around with FPDF in a while, but I'm pretty certain you'll either need to delete the PDF file that's generated before creating a new one with the same name, or you'll need to use a different name for each PDF file created.

Thanks Aken,

Sorry that was an error in my post, In this instance, the filename is generated by the mySQL auto incrementing ID, and a rand md5() has in the file name, is is never the same.

Here is the working code,

CI is great for including a sinlge library instance, but there is no way ( That I know of ) to unset a library.

Code:

<?php

    // inside my CI controller
        
        
        function monthly() {
            
//            Load PDF Library - the original PHP way
             require_once('libraries/pdf.php');
//            Load and initialise CI Email library
            $this->load->library('email');
            $this->email->initialize(array('mailtype' => 'html'));

//            start loop - approx 15 records            
            $monthlies = $this->invoice->getMonthlies();
            if($monthlies) {
                foreach($monthlies as $monthly) {
                    
//                    Load CI/FPDF library
                    $this->load->library('pdf');
                    
//                    Create PDF ( I have remove unnesscary code that pulls data for PDF. )
//                    Make a random filename
                    $filename   = md5(time() * rand(100, 1000)) .'.pdf';
//                    generate a random varible name
                    $pdf  = time();
//                    assign my PDF Class to my random name.
                    $$pdf = new Pdf();
                    
//                    Pass in my filename for output AND my randomly named PDF class
                    $this->load->view('pdf/invoice', array('pdf' => $$pdf, 'filename' => $filename));

//                    unset my random PDF name - Do I need to, unsure, but heck, why not !
                    $pdf = md5(time());
                    
//                    validate customer email and sent PDF.
                    if(valid_email($email)) {

                        $this->email->from($this->config->item('admin_mail'));
                        $this->email->to($email);
                        $this->email->reply_to($this->config->item('admin_mail'));

                        $this->email->subject('Invoice #'. $invoice_id);
                        $this->email->message($this->load->view('admin/email', array('customer' => $customer, 'invoice' => $invoice), TRUE));
                    
//                        Attach my PDF, send and clear email + all attachemnts
                        $this->email->attach($filename);
                        $this->email->send();
                        $this->email->clear(TRUE);
                    
                    }
//                end loop
                }
                
            }
            
//            finished
            redirect();
        }
    
    }
