# How to use automatic schema with MyListing WordPress theme

## First step

The first thing to do is adding this filter to your functions.php of your child theme (or theme / [must use plugin](https://www.seopress.org/support/guides/how-to-create-a-mu-plugin/)) to show hidden fields in the **SEO**, **Schemas**, **Custom fields dropdowns**:

```
function sp_get_custom_fields($cf_keys) {
    //example to show all custom fields including hidden ones
    global $wpdb;
    
    $limit = (int) apply_filters('postmeta_form_limit', 650);
    
    $cf_keys = $wpdb->get_col("
			SELECT meta_key
			FROM $wpdb->postmeta
			GROUP BY meta_key
			HAVING meta_key NOT LIKE '\_seopress%%'
			ORDER BY meta_key
			LIMIT $limit");

    return $cf_keys;
}
add_filter('seopress_get_custom_fields', 'sp_get_custom_fields');
```

Note the “**650**” value. This is the number of the max number of custom fields you can see in the select (default: 250 for performance reasons).

Increase the value if necessary.

## Second step

Add a custom taxonomy called “**Schemas**” under **Listings post type**. From this taxonomy, add some schema names like Local Business, Events, Courses… Then, edit a listing and apply the correct term. Eg: if you have an enterprise directory, add the Local Business term to these enterprises.

You can also use the bulk edit feature from the **Listings list**: select some posts, click **Edit** from the **Bulk actions** dropdown and **Apply**.

Why we need this? To target your content with a specific automatic schema.

## Third step

Go to **SEO**, **Schemas**, **edit** your **automatic schema**. In the **Rules section**, select **Post type is equal to Listings AND taxonomy is equal to Local Business**.

**MyListing** saves its data in post meta table (ie: custom fields) starting by “**\_job\_**name\_of\_your\_custom\_field”.

Map your data by selecting custom fields, custom taxonomies etc. You can also use this filter to add your own [predefined dynamic variable](https://www.seopress.org/support/hooks/filter-predefined-dynamic-variables-for-automatic-schemas/).

The easiest to map all the schema properties for Google is to create their equivalent with custom fields in MyListing.

Save changes.

Clear your cache if necessary.

## Final step

Test one of your URL with [Google Structured data testing tool](https://developers.google.com/search/docs/advanced/structured-data) to make sure everything is working as expected.

Disable also the schema generated by MyListing to avoid duplicated schemas.

Et voilà !
