The topmost array holds the sections, keyed by section ID. @type array ...$0 { Each section has a `$fields` associative array (see below), and each `$value` in `$fields` can be another associative array of name/value pairs when there is more structured data to display. @type string $label Required. The title for this section of the debug output. @type string $description Optional. A description for your information section which may contain basic HTML markup, inline tags only as it is outputted in a paragraph. @type bool $show_count Optional. If set to `true`, the amount of fields will be included in the title for this section. Default false. @type bool $private Optional. If set to `true`, the section and all associated fields will be excluded from the copied data. Default false. @type array $fields { Required. An associative array containing the fields to be displayed in the section, keyed by field ID. @type array ...$0 { An associative array containing the data to be displayed for the field. @type string $label Required.

    Required: Yes
Defined at:

Filters the debug information shown on the Tools -> Site Health -> Info screen.

Plugin or themes may wish to introduce their own debug information without creating additional admin pages. They can utilize this filter to introduce their own sections or add more data to existing sections.

Array keys for sections added by core are all prefixed with wp-. Plugins and themes should use their own slug as a prefix, both for consistency as well as avoiding key collisions. Note that the array keys are used as labels for the copied data.

All strings are expected to be plain text except $description that can contain inline HTML tags (see below).
