使用 fpdf 库打印数据时数据未传入 codeigniter

Question

我有表格，我正在显示 data.When 我点击打印按钮我将以 pdf 格式保存数据以便打印我正在使用 FPDF Library.The 问题是什么时候我从控制器发送数据以仅查看 headers 显示如下但数据未显示。我已经编写了我的视图文件 below.I 自从 yesterday.I 以来就卡住了已在控制器中获取数据但未传递给 view.I 无法理解为什么会发生这种情况。我做错的方式或请任何帮助提前 Appreciated.Thanks。

我的控制器代码

 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');
                 }

                 }

我从数据库中获取数据的模态代码

  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();
      }
    }

我将数据打印为 pdf 格式的查看代码

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();

这是 Fdf 库 class

require('fpdf/fpdf.php');

class Myfpdf extends fpdf
{
function __construct(){
  parent::__construct();
  $ci=& get_instance();
}

}

Answer 1

尝试将 $result 数据作为参数传递：

$this->pdf->viewdata($result);

还有方法：

function viewdata($result){
...
}

Answer 2

我已经改成现在可以正常使用了。

   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');
                 }

                 }

这是视图文件

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();

使用 fpdf 库打印数据时数据未传入 codeigniter

While printing data using fpdf library Data is not passing in codeigniter

php

mysqli

fpdf

codeigniter-3

我的控制器代码

我从数据库中获取数据的模态代码

我将数据打印为 pdf 格式的查看代码

这是 Fdf 库 class

这是视图文件
