i want to save my view file as a pdf using mpdf library. my controller function looks like as below. this function will get the invoice_no . it will check if the pdf file already exists on the server or not. if the pdf file already exists, the function will download that file automatically. if the file does not exist, it will generate new pdf file and display that file on browser and it will show an option to save that file as show below on the screenshot
function generate_pdf()
{
$this->load->helper('download');
if(isset($_GET['action'])&& isset($_GET['id']))
{
$invoice_no = $_GET['id'];
$download = true;
}
else
{
$download = false;
}
$agent_id = $this->session->userdata('agent_id');
$agent_email = $this->session->userdata('agent_email');
$file = FCPATH.'invoice pdf files/'.$agent_email.'/Invoice '. $invoice_no.'.pdf';
if(file_exists($file) && ( $download==true))
{
$data = file_get_contents($file);
$name = 'Invoice '. $invoice_no.'.pdf';
force_download($name, $data);
}
else
{
$agent_id = $this->session->userdata('agent_id');
$agent_email = $this->session->userdata('agent_email');
$file = FCPATH.'invoice pdf files/'.$agent_email.'/Invoice '. $invoice_no.'.pdf';
$invoice_details = $this->agents_model->get_result_array('tbl_portal_payment_history',array('agent_id'=>$agent_id, 'invoice_no'=>$invoice_no));
$transaction_details = $this->agents_model->get_result_array('tbl_portal_invoice_number',array('agent_id'=>$agent_id, 'invoice_no'=>$invoice_no));
$invoice_date = $transaction_details[0]['invoice_registration_date'];
$invoice_date = strtotime($invoice_date);
$invoice_date = date('D, F j\<\s\u\p\>S\<\/\s\u\p\>, Y',$invoice_date);
$data['invoice_date'] = $invoice_date;
$date = date("h:i:sa");
$date = strtotime($date);
$data['today_date'] = date('l, F j\<\s\u\p\>S\<\/\s\u\p\>, Y',$date);
$agent_details = $this->agents_model->get_row_array('tbl_agents', array('id'=>$agent_id));
$data['agent_name'] = $agent_details['first_name'].' '.$agent_details['last_name'];
$data['address2'] = ($agent_details['address2']!='')? $agent_details['address2'].', ':'';
$data['city'] = ($agent_details['city']!='')? $agent_details['city'].', ':'';

$data['agent_details'] =$agent_details;
$data['invoice_details'] =$invoice_details;
$data['transaction_details'] =$transaction_details;
$data['invoice_no'] =$invoice_no;
$html = $this->load->view('agents/invoices/invoice_pdf_view',$data);
$main_folder = base_url('invoice pdf files/');
$sub_folder = base_url('invoice pdf files/'.$agent_email.'/');
$filename = 'Invoice '.$invoice_no;
if(!is_dir($main_folder)){
mkdir('invoice pdf files');
mkdir('invoice pdf files/'.$agent_email.'/');
}
if(!is_dir($sub_folder)){
mkdir('invoice pdf files/'.$agent_email.'/');
}
$pdfFilePath = FCPATH.'invoice pdf files/'.$agent_email.'/'.$filename.'.pdf';
$this->load->library('pdf');
$pdf = $this->pdf->load();$pdf->WriteHTML($html);
$pdf->Output($pdfFilePath, 'F');
$pdf->Output();
}
}
