Shortcode
Besides normal ways to display fields on the website, Meta Box also provides a simple shortcode [rwmb_meta] to help you show custom fields in the post content or widgets easily.
[rwmb_meta id="field_id" object_id="15"]
Attributes
| Attribute | Description |
|---|---|
id | The field ID. Required. |
object_id | The object ID. Optional. If not defined, then the current object ID is used. |
attribute | Get a single attribute from the field value (such as URL of the image or term slug). The field value is get with the rwmb_get_value() helper function. This works only when the value is an array. |
render_shortcode | Whether to render inner shortcodes inside the value of the field. For example, if you enter a shortcode in a textarea/editor field, this attribute will render that shortcode and return the rendered content. Default true. |
This shortcode works exactly like the rwmb_the_value() function with the same parameters.
You can pass other attributes to the shortcode if you want. If you do so, those attributes will be passed to the rwmb_the_value() function as the 2nd parameter.
Examples
Getting the value of a text field:
[rwmb_meta id="phone"]
Getting image URL (single_image):
[rwmb_meta id="company_logo" attribute="url" size="thumbnail"]
Getting a term meta:
[rwmb_meta id="color" object_id="15" object_type="term"]
Getting a settings:
[rwmb_meta id="phone" object_id="site_option" object_type="setting"]
Getting a field value from a custom table:
[rwmb_meta id="area" object_id="15" storage_type="custom_table" table="properties"]
Bypass HTML filtering
By default, the shortcode will be filtered by the wp_kses_post() function to remove all insecure HTML tags and attributes. If you want to bypass this filtering, you can use the rwmb_meta_shortcode_secure filter:
add_filter( 'rwmb_meta_shortcode_secure', '__return_false' );
To bypass HTML filtering for a specific field, you can use the rwmb_meta_shortcode_secure_{$field_id} filter:
add_filter( 'rwmb_meta_shortcode_secure_footer_script', '__return_false' );
