How to apply these filters

Question

I bought woocommerce compare plugin. Unfortunately I can't understand how to apply some filters.

For example I want to increase compare limit tom 10. How ı can use below filte?

apply_filters( ‘woocommerce_products_compare_max_products’, int ) – sets how many products can be compared at one time. Default is 5.

What I tried but not working;

   function comparelimit($location){
       $location = 10;
    }
    apply_filters( ‘woocommerce_products_compare_max_products’, 'comparelimit');

Answer 1

You need to return the value in the function for it to be accessible outside that function

function comparelimit( $location ) {
    $location = 10;
    return $location;
}
add_filter( 'woocommerce_products_compare_max_products', 'comparelimit' );

Both are working now :) I don't know what changed.

Here is code for change product-compare page to what ever you want

function comparerename()
{
    return 'karsilastir';
}
add_filter('woocommerce_products_compare_end_point' ,'comparerename');

here is the code to change compare limit

function comparelimit( $location ) {
    $location = 8;
    return $location;
}
add_filter( 'woocommerce_products_compare_max_products', 'comparelimit' );

If anyone can teach me how to use below one, that would be great.

apply_filters( ‘woocommerce_products_compare_compare_button’, html ) – filters the display of the compare products button.

apply_filters( ‘woocommerce_products_compare_meta_headers’, array ) – filters the headers displayed on the compare products page.

Weirdly this solved my problem.I am not sure if woocommerce's documentation is wrong.

    function comparelimit( $location ) {
    $location = 10;
    return $location;
}
add_action( 'woocommerce_products_compare_max_products', 'comparelimit' );
