How to create same pdf file multiple time using tcpdf in codeigniter? - php

Question

I'm using tcpdf library for pdf creation. I want to download same pdf multiple time(user will enter how many pdfs he want). I made a for loop which call pdf function according to the user entered value. The problem is code stop after creating first pdf. Following is my pdf function which I call multiple time. Also it take about 10-15 seconds to create pdf. Thanks!
public function generatePdf($eventId) {
$eventDetails = $this->events_model->getAttachment($eventId);
$image = $eventDetails[0]->image_source;
$startTime = $eventDetails[0]->startTime;
$regTime = $eventDetails[0]->regTime;
$locationName = $eventDetails[0]->location_name;
$location = $eventDetails[0]->location;
$date = strtotime($startTime);
$date1 = strtotime($regTime);
$dat = date('m/d/y', $date);
$tme = date('H:m', $date);
$regTme = date('m/d/ H:m', $date1);
