Meta Box – WordPress Custom Fields Framework [rwmb_meta] Shortcode

The Meta Box shortcode allows for the extraction and display of custom field data. This shortcode accepts attributes like ‘id’, ‘object_id’, and ‘attribute’. It checks if the ‘id’ attribute is empty and if so, returns an empty string. The ‘id’ and ‘object_id’ attributes are used to get the value of the custom field. If ‘render_shortcodes’ is set to true, any shortcodes in the value are processed.

Shortcode: [rwmb_meta]

Parameters

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

• id – Unique identifier for the meta field
• object_id – The ID of the post or user to fetch metadata from
• attribute – Additional attributes for the field
• render_shortcodes – Determines if shortcodes within the field value should be rendered

Examples and Usage

Basic example – A shortcode that uses the ‘rwmb_meta’ function to fetch a specific meta field value by its ID.

[rwmb_meta id='meta_field_id' /]

Advanced examples

Displaying a meta field value by its ID, but also specifying the object ID. This is useful when you want to fetch a meta field value from a specific post or page.

[rwmb_meta id='meta_field_id' object_id='123' /]

Displaying a meta field value by its ID, specifying the object ID, and disabling the rendering of nested shortcodes within the meta field value.

[rwmb_meta id='meta_field_id' object_id='123' render_shortcodes='false' /]

Displaying a meta field value by its ID, specifying the object ID, and defining a custom attribute. This is useful when you want to pass additional parameters to the shortcode.
