Product attributes

Hello @gsmtricks,

Thank you for contacting the support.

We provide a filter that you can use to add custom variables:
https://rankmath.com/kb/filters-hooks-api-developer/#add-extra-variables

You can refer to the following code:
https://github.com/rankmath/seo-by-rank-math/blob/master/includes/modules/woocommerce/class-wc-vars.php#L24

With that being said, there are existing feature requests, so I’ve added your vote to our internal suggestions lists. If your suggestions are something that we’re able to introduce, I’ll be sure to let you know.

If there’s anything else we can help you with, please let us know. We are here to assist.

Could you validate it?

I have attribute: Supported by
slug for this attribute: supported-by

add_action( ‘rank_math/vars/register_extra_replacements’, function(){
rank_math_register_var_replacement(
‘supported-by’,
[
‘name’ => esc_html__( ‘Attribute: Supported by’, ‘rank-math’ ),
‘description’ => esc_html__( ‘Custom variable description.’, ‘rank-math’ ),
‘variable’ => ‘supported-by’,
‘example’ => ‘supported-by_callback()’,
],
‘supported-by_callback()’
);
});

Hello @gsmtricks

Here is the updated code:

add_action( 'rank_math/vars/register_extra_replacements', function() {
	rank_math_register_var_replacement(
		'supported-by',
		[
			'name' => esc_html__( 'Attribute: Supported by', 'rank-math' ),
			'description' => esc_html__( 'Custom variable description.', 'rank-math' ),
			'variable' => 'supported-by',
			'example' => supported_by_callback(),
		],
		'supported_by_callback'
	);
} );

function supported_by_callback() {
	// Add your code here to get the attribute value..
	return 'Supported by value..';
}

Hope that helps. Thank you.
