Creating a Dynamic PDF and Saving it in a folder using Loop with MYSQL and Codeigniter - codeigniter

Question

This is the public function with looping (Edited)
public function generate_salary_slip(){
$this->load->helper('file');
$this->load->library('m_pdf');
$data = [];
$slip = $this->Admin_Login_Model->generate_salary_slip();
//$html = array();
$html='';
if(!empty($slip)){
foreach($slip as $slip_list){
$id = $slip_list->emp_id;
$data['attendance'] = $this->Admin_Login_Model->get_slip_attendance($id);
$data['emp_profile'] = $this->Admin_Login_Model->get_emp_details($id);
$data['late_day'] = $this->Admin_Login_Model->get_late_days($id);
$data['half_days'] = $this->Admin_Login_Model->get_half_days($id);
$data['salary'] = $this->Admin_Login_Model->get_salary_slip($id);
$data['second_half'] = $this->Admin_Login_Model->get_half_Second_days($id);
//$html=$this->load->view('admin/payslip',$data);
$pdfFilePath = date("F_Y")."salary_slip.pdf";
$html .= $this->load->view('admin/payslip', $data, true);
}
$htmlval = $html;
//echo $html;exit;
$this->m_pdf->pdf->WriteHTML($htmlval);
$this->m_pdf->pdf->Output('salary_slips/'.$pdfFilePath, "F");
$this->session->set_flashdata('success','Salary slips saved in directory!');
redirect('admin_attendance_list');
}else{
$this->session->set_flashdata('message','Salary slips not available for this month!');
redirect('admin_attendance_list');
}
}
File is getting saved in the folder, but Only with the First Record. Also, Repeated loop is getting generated, but with same record.
How to create a HTML by loop.
PS: Using MPDF to generate PDF File
Any hep will be highly appreciated.

Answer 1

You need to take the render, writeHtml and Output calls outside the forech loop, there is you problem.
You could save all the data in a var and then render the HTML as you are doing now and then generate the PDF.
EDIT: Your code should look something like this (please read comments below):
$htmlData = array();
if(!empty($slip)){
foreach ($slip as $slip_list) {
//
$htmlData[] = $data;
}
$pdfFilePath = date("F_Y")."salary_slip.pdf";
$html = $this->load->view('admin/payslip', $htmlData, true);
$this->m_pdf->pdf->WriteHTML($html);
$this->m_pdf->pdf->Output('salary_slips/'.$pdfFilePath, "F");
