wp export is not exporting term meta data

[sudar]

The wp export command is not exporting term meta data.

But the WXR file created directly from wp-admin ui (Tools -> Export) includes the term meta data.

Steps to reproduce

• Add term meta data to a specific term using either the update_term_meta or add_term_meta function
• Verify that this data is present in wp_termmeta table
• Export the contents of the site by running the wp export command
• The exported WXR file will not have this term meta data. This can be confirmed by doing a grep for wp:termmeta
• Alternatively export from wp-admin ui by going to Tools -> Export
• The exported WXR file will contain the term meta data. This can be confirmed by doing a grep for wp:termmeta

Up please ;)

I'm gonna try to quick fix it for now.

WP does it in includes/export.php on line 312

Here's the code :

/**
	 * Output term meta XML tags for a given term object.
	 *
	 * @since 4.6.0
	 *
	 * @param WP_Term $term Term object.
	 */
	function wxr_term_meta( $term ) {
		global $wpdb;

		$termmeta = $wpdb->get_results( $wpdb->prepare( "SELECT * FROM $wpdb->termmeta WHERE term_id = %d", $term->term_id ) );

		foreach ( $termmeta as $meta ) {
			/**
			 * Filters whether to selectively skip term meta used for WXR exports.
			 *
			 * Returning a truthy value to the filter will skip the current meta
			 * object from being exported.
			 *
			 * @since 4.6.0
			 *
			 * @param bool   $skip     Whether to skip the current piece of term meta. Default false.
			 * @param string $meta_key Current meta key.
			 * @param object $meta     Current meta object.
			 */
			if ( ! apply_filters( 'wxr_export_skip_termmeta', false, $meta->meta_key, $meta ) ) {
				printf( "\t\t<wp:termmeta>\n\t\t\t<wp:meta_key>%s</wp:meta_key>\n\t\t\t<wp:meta_value>%s</wp:meta_value>\n\t\t</wp:termmeta>\n", wxr_cdata( $meta->meta_key ), wxr_cdata( $meta->meta_value ) );
			}
		}
	}

Edit.
I added the following function (same as comment_meta()) :

protected function term_meta($term)
	{
		global $wpdb;
		$termmeta = $wpdb->get_results($wpdb->prepare("SELECT * FROM $wpdb->termmeta WHERE term_id = %d", $term->term_id));
		if (!$termmeta) {
			return new Oxymel();
		}
		$oxymel = new WP_Export_Oxymel_Snake();
		foreach ($termmeta as $meta) {
			$oxymel->tag('wp:termmeta')->contains
				->tag('wp:meta_key', $meta->meta_key)
				->tag('wp:meta_value')->contains->cdata($meta->meta_value)->end
				->end;
		}
		return $oxymel;
	}

And it is called here :

->oxymel($this->term_meta($term));

	protected function terms($terms)
	{
		$oxymel = new WP_Export_Oxymel_Snake();
		foreach ($terms as $term) {
			$term->parent_slug = $term->parent ? $terms[$term->parent]->slug : '';
			$oxymel->tag('wp:term')->contains
				->tag('wp:term_id', $term->term_id)
				->tag('wp:term_taxonomy', $term->taxonomy)
				->tag('wp:term_slug', $term->slug)
				->oxymel($this->term_meta($term));

			if ('nav_menu' !== $term->taxonomy) {
				$oxymel
					->tag('wp:term_parent', $term->parent_slug);
			}

			$oxymel
				->optional_cdata('wp:term_name', $term->name)
				->optional_cdata('wp:term_description', $term->description)
				->end;
		}
		return $oxymel->to_string();
	}

I take this issue.

I have done the test manually with success.
I have also tested successfully the import of the exported XML file.

The command composer behat doesn't work on my computer. It always returns this error ERROR 1045 (28000): Access denied for user 'wp_cli_test'@'localhost' (using password: YES)
So I could not run the automatic tests.

composer behat works well now on my computer.
I have added a scenario and 2 tests.
All the tests are successful.
