Can't require_once fdpf/fpdf.php

Question

I am using the FPDI library from JanSlabon for securing PDF file uploads from my laravel app. But I can't execute the code require_once even though I navigated to the file itself. I am getting the error:

Failed opening required '../../vendor/setasign/fpdf/fpdf.php' (include_path='.:/usr/local/Cellar/php/7.3.4/share/php/pear')

My require code is:

require_once('../../vendor/setasign/fpdf/fpdf.php');
require_once('../../vendor/setasign/fpdi/src/autoload.php');

Answer 1

When the libraries are already located in your vendor folder, you should simply make use of the autoload.php file of composer (doesn't laravel uses this by default?).

So just add the dependencies to your composer.json (if not already done):

"require": {
    "setasign/fpdf": "^1.8",
    "setasign/fpdi": "^2.2",
    "setasign/fpdi-protection": "^2.0"
}

Update via composer update and:

<?php
use setasign\FpdiProtection\FpdiProtection;

require_once('vendor/autoload.php');

$pdf = new FpdiProtection();
