# get meta guids

This block is part of the [`array`](https://docs.rual.nl/block-types/array) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

Returns an array of values with _meta.guid's of each object in the given array.

- Array required `array` Array with Objects (e.g. results of a search)

- Array `array` Array with guids

Extracts _meta.guid from each object item into a flat array of guid strings, preserving order. Items that are not objects, lack _meta, or have an empty guid are SKIPPED, so the output can be shorter than the input.

A typical wiring for [get meta guids](https://docs.rual.nl/block-types/array/array_guid_map): [filter](https://docs.rual.nl/block-types/array/array_filter) feeds the `array` pin; the `array` out pin feeds [add suffix to values](https://docs.rual.nl/block-types/array/array_add_suffix).
