I want to change values of the variable in my theme. I don't want to edit in this file because after update theme, it will be lost.

So, I want to update values of this variable in functions.php.

In post-simple.php file:

<p class="from_the_blog_excerpt small-font show-next">
    $excerpt      = get_the_excerpt();
    echo flatsome_string_limit_words( $excerpt, 15 );

I want to change values 15(the length of string) to another value in the function flatsome_string_limit_words($excerpt, $length).

In functions.php of child theme, I write this code look like:

function custom_excerpt_length( $excerpt, $length ) {
    $length = 30;
    return $length;
add_filter( 'flatsome_string_limit_words', 'custom_excerpt_length', 999 );

I tried to change values of $length to values 30 instead of 15 like default set on post-simple.php file.

But it does not a success. It still return $length = 15.

    consider to contact the developer of your theme; the function flatsome_string_limit_words() is theme specific, and the developer might be the best to help with your question.

Are you sure the flatsome_string_limit_words hook exists inside the string_limit_words function?

I think your best option is to override whole post-simple.php template in your child, but even this depends on how is built the parent theme.
