Creating Article Custom Fields - Part 1

This article will illustrate how to add custom fields to any page type in the Joomla! framework.

Core Joomla! extensions that have their own custom fields are:

• Articles
• Categories
• Users
• Contacts

We will show how to create and implement these custom fields directly into a module, category page, and custom (pre-made) layouts using real use cases found in this template.

Create New Article Custom Field

Creating a basic custom field (from the Admin Dashboard):

• Content > Field Groups > New
• We are going to title it 'Pricing' 
• Save and Close
• Content > Fields > New
• Title it 'Price'
• Select Filter 'Text'
• Click on the 'Options' tab
• Under 'Display Options', find the 'Automatic Display' field
• Select 'Do not automatically display'
• Save & Close

Create Article Layout Override

• System > Site Templates
• Select your active template (Site example is My Template)
• Select the 'Create Overrides' Tab
• Components> com_content > article (click)
• This will create a new layout titled 'default' in your '/templates/html/com_content/article' directory
• Rename this file to 'price' so the filename should be 'price.php'

Create New Article With Override

• Content > Articles > New
• Add a title 'Price Example'
• Select the 'Options' Tab
• Find 'Layout' Field and select the new layout you created: 'price'
• Select the 'My Template' Tab
• Find the 'Price' field you created earlier and enter '$450'
• Save & Close

Conclusion

After following the steps above, the following items should be completed before moving to the next article:

1. Article custom field group titled 'Pricing'
2. Article custom field titled 'Price'
3. Article layout override named 'price.php'
4. New article using the 'price' layout file & a value of '$450' in the 'Price' field under the 'Pricing' tab
