In this tutorial, we will show you how to parse a PDF Invoice using the PDF.co Document Parser Web API. Using PHP, we will add the parsed data as a new record in a database table. We divided this tutorial into three (3) sections. Feel free to explore each part using the content links above.

Document Parser Template Creation Guide

We will start this tutorial by creating our template. Kindly go to the Document Parser page in PDF.co and click on the New Template link. Here’s a direct link to the Document Parser Template Editor.

Add Field Based On Text Search Object
First, click on the Load Test PDF or Image button to open your document in the editor.

Then, click on the +Add Object button and select Add FIELD based on TEXT SEARCH.

Search Invoice Number Using Macros
Let’s get the Invoice number. In the Expression field, enter Invoice number:{{Spaces}}({{Digits}}). Then, check the Regex box.

Do the same for the Issue Date and Amount Due. To save you time, you can download the template here.

 

PHP Sample Code Walkthrough

Let’s explore the PHP sample code and review the parts to add your server and database information. To follow along, here’s the link to the PHP code.

Database Information

In the InsertToDb function, you can add your $servername, $username, $password, and $dbname values.

Database Table Information

From lines 123 to 128, you can add your database table and fields information. If you would like to use our default values, you’ll need a database table called sample_table and fields inv_no, inv_date, and inv_total.

 

Parse PDF and Fill Database Demo

We are now ready to run our program. Kindly download the Google.pdf, Google Invoice.json, program.html, and program.php here. Be sure to add your server and database information in the program.php if you’re using different names. Then, move the program.html and program.php files to your /www directory.

In this demonstration, we will only parse the Invoice Number, Invoice Date, and Amount Due from the Google invoice.
