Advanced Custom Fields (ACF) [acf] Shortcode

The Advanced Custom Fields shortcode is a powerful tool that allows you to display custom field data. It works by retrieving the field value based on the ‘field’ and ‘post_id’ attributes. This shortcode is also equipped with security measures to prevent unauthorized users from previewing or manipulating data. It restricts AJAX requests and limits data previews to users with ‘publish_posts’ permissions. Shortcode: [acf] Furthermore, it includes a filter to prevent access to unknown fields, ensuring data integrity and security. If the field value is an array, it converts it into a string for display. Shortcode: [acf]

Shortcode: [acf]


Here is a list of all possible acf shortcode parameters and attributes:

  • field – Specifies the field name from which data is fetched.
  • post_id – Identifies the post to fetch the field data from.
  • format_value – Controls whether to format the field value or not.

Examples and Usage

Basic example – Displaying a field value by using the field name as the attribute.

Advanced examples:

Displaying a field value by using the field name and post ID as the attributes. This will fetch the field value from a specific post.

The format_value attribute is used to control whether the value returned by the shortcode should be formatted or not. If set to true, the value will be formatted based on the field type. If set to false, the raw value stored in the database will be returned.

[acf field="my_field_name" post_id="123" format_value="true"]
