I have written my view file like below.I have got stuck since yesterday.I Have getting the data in controller but not passing to the view.I can't understand why it is happening .The Way i am doing wrong or what please any help Would be Appreciated.Thanks in Advance.
My controller Code
public function printpage(){
$this->load->library('Myfpdf');
$data['result']=$this->Vendor_Model->displaydata();
if(!empty(array_filter($data))){
$this->load->view('Savedata',$data);
}else{
redirect('Vendorcontroller/showeditview');
}
}
My Modal code for getting the data from the database
public function displaydata(){
$query=$this->db->query('SELECT `vndr_id`, s.state as state,`vndr_name`, `vndr_address`, `vndr_pincode`, `vndr_telephone`, `vndr_mobile`, `vndr_mailid`, `vndr_country`, `vndr_gsttin`, `vndr_cstno`, `vndr_totaldebit`, `vndr_totalcredit`, `vndr_bankname`, `vndr_acno`, `vndr_ifsccode` FROM `vendors` vndr INNER JOIN states s ON vndr_state=s.state_id order by vndr_id');
if($query->num_rows()>0){
return $query->result_array();
}
}
My view code for print the data as pdf format
class printview extends FPDF
{
function Header()
{
$this->SetFont('Arial','B',15);
$this->Cell(276,5,"VendorDetails",0,0,'C');
$this->ln(15);
$this->SetFont('Arial','B',10);
$this->Cell(55,10,"Name",1,0,'C');
$this->Cell(90,10,"Address",1,0,'C');
$this->Cell(50,10,"Telephone",1,0,'C');
$this->Cell(70,10,"Email",1,0,'C');
$this->ln();
}
function Footer(){
$this->SetY(-15);
$this->SetFont('Arial','I',8);
$this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
function viewdata(){
if(isset($result)){
foreach($result as $values){
$this->SetFont('Arial','',10);
$this->Cell(55,10,$values['vndr_name'],1,0,'L');
$this->Cell(90,10,$values['vndr_address'].','.$values['state'].'-'.$values['vndr_pincode'],1,0,'L');
$this->Cell(50,10,$values['vndr_telephone'].','.$values['vndr_mobile'],1,0,'L');
$this->Cell(70,10,$values['vndr_mailid'],1,0,'L');
$this->ln();
}
}
}
}
$this->pdf = new Printview();
$this->pdf->SetMargins(15, 10, 20);
$this->pdf->AliasNbPages();
$this->pdf->AddPage('L','A4',0);
$this->pdf->viewdata();
$this->pdf->Output();
This is Fdf library class
require('fpdf/fpdf.php');
class Myfpdf extends fpdf
{
function __construct(){
parent::__construct();
$ci=& get_instance();
}
}

Answer 1

Try to pass the $result data as a parameter :
$this->pdf->viewdata($result);
And also on the method :
function viewdata($result){
...
}

Answer 2

I Have changed this way it is working fine now.
This is controller
-------------------------
public function printpage(){
$this->load->library('Myfpdf');
$data['result']=$this->Vendor_Model->displaydata();
if(!empty(array_filter($data))){
$this->load->view('Savedata',$data);
}else{
redirect('Vendorcontroller/showeditview');
}
}
This is view file
function viewdata($result){
if(isset($result)){
foreach($result as $values){
$this->SetFont('Arial','',10);
$this->Cell(55,10,$values['vndr_name'],1,0,'L');
$this->Cell(90,10,$values['vndr_address'].','.$values['state'].'-'.$values['vndr_pincode'],1,0,'L');
$this->Cell(50,10,$values['vndr_telephone'].','.$values['vndr_mobile'],1,0,'L');
$this->Cell(70,10,$values['vndr_mailid'],1,0,'L');
$this->ln();
}
}
}
}
$this->pdf = new Printview();
$this->pdf->SetMargins(15, 10, 20);
$this->pdf->AliasNbPages();
$this->pdf->AddPage('L','A4',0);
$this->pdf->viewdata($result);
$this->pdf->Output();
