Application Features
The application contains the following features:- Front End
- User Registration Login
- Custom Post Type (vehicles / invoices) Creation / Removal / Edits
- Content filtering
- content search
- mailing, printing, phone calls
- Admin User Approval
- Admin Content Management and Edits
Coding Approach / Used Plugins
To reduce the application in size and assure its scalability we’ve decided to use available Gravity Forms filters and hooks along with the power of Custom Post Types. The project is also using the Timber plugin and has been built with the Chisel generator framework provided by Xfive.co. Chisel, being a gulp based tool allows us to modularize .css and .js code, assuring proper and easy to maintain code structure. Once compiled the code is merged, minimized and deferred giving us a solid base for a mobile-optimized project. Gravity forms plugin was used to setup all Front End facing forms. Its hooks and filters (some of these have been explained by us in the Gravity Forms blog series) were combined with ACF created post fields. Upon each form submission, the data is being saved as either Invoice or Vehicle directly inside the WordPress database.Sample Code Snippets
The section covers sample Gravity Forms code snippets. The plugin has a lot of nice hooks that allow one to execute any code after the occurrence of a specific action, for instance: form submission, form validation, or form rendering. Similarly, the latter gives one an ability to pre-populate Gravity Form’s form with any arbitary data. In other words, we fetched the data from the database, pre-populating the form with user input values. 1. Gravity Forms Login Submission Handler 2. ACF to Gravity Forms pre-populationSummary

Final Words

As a result, we always try to take into account the fact that some other team may work after us and we try to keep the code as clean and well written as possible. Furthermore, programming is not an easy task. It may be frustrating, it may require a lot of iterations, fixes, debugging, patience, ongoing maintenance, code updates and support.
