Install PDFTk on Ubuntu 18.04 Bionic

pdftk is missing from the official repository right now. That’s an issue for many people.

I needed PDFTK to be installed on Ubuntu (18.04) due to the need to manipulate PDFs. Unfortunately, because I used Laravel Forge, they only allow Ubuntu, and apparently PDFtk is not longer working with Ubuntu 18.04. There is a workaround! Follow the below to get it working.

There’s a workaround here: How can I install pdftk in Ubuntu 18.04 Bionic?

Quick and easy workaround

In SSH on your Ubuntu 18.04 server, do the below:

sudo dpkg -i pdftk_2.02-4build1_amd64.deb libgcj17_6.4.0-8ubuntu1_amd64.deb libgcj-common_6.4-3ubuntu1_all.deb

Then type ‘pdftk’, it should come up.

Hope that helps!

Laravel DOM-PDF Error – No block-level parent found. Not good.

I received this error when using a system called FusionInvoice. This relates to DOM PDF which is a Laravel vendor to allow PDFs to be created.

Error said something along the lines of  ‘No block-level parent found. Not good.’.

To fix this error, I went to my file structure and edited /vendor/dompdf/dompdf/

Look for:


Replace with:


This should fix the issue

Change Australian mobile numbers to +61 in PHP

Recently, I was using Laravel to build an online ordering system for a restaurant. The website required users to sign up and type in an SMS verification code to activate their account. Using Twilio, we wanting the phone number to come up as the business name instead of a phone number. When signing up though, Twilio required the phone number to be in international format (Eg. +6140122222) instead of 0401222222. So, we faced the dilemma of either using javascript to replace it, or just do it in PHP so that the user will not know any different.

It was really quite easy,

$phone = '0422222222';
$formatted = substr_replace($phone,"+61",0,2);

The phone number will be displayed like +614222222 in the $formatted variable.

Obviously this will work for other countries as well, but might be easier in Australia as we only have one type of mobile number starting with ’04’.

Hope that helps!
