Adding function to child theme's function.php

Question

I am trying to do some edits to my parent theme. I have made a child theme so that updating the parent wont cause a problem.Now I want to add a certain function that is in the parent theme's functions.php to the functions.php file of the child theme. I am using Oblique theme. Here is the function from the parent file :

function oblique_post_link_to_single() {

    if ( ! get_theme_mod( 'read_more' ) ) :?>
        <a href="<?php the_permalink(); ?>">
            <div class="read-more">
                <?php echo apply_filters(
                      'oblique_post_read_more'
                    , esc_html__( 'Continue Reading &hellip;','oblique' )
                );?>
            </div>
        </a>
    <?php
    endif;

}

add_action( 'oblique_link_to_single','oblique_post_link_to_single' );

I tried pasting the code into the child theme but doing so gave me an http 500 error and crashed my website. I need to make some changes in this function inside the child theme and make sure this over rides the parent function.

You can't recall the same function or PHP will throw an error. Make your own function and call the same action hook, but give it a priority of 1 which should overrule the parent theme function.

function custom_oblique_post_link_to_single() { if ( ! get_theme_mod( 'read_more' ) ) :?> <a href="<?php the_permalink(); ?>"> <div class="read-more"> <?php echo apply_filters( 'oblique_post_read_more' , esc_html__( 'Continue Reading &hellip;','oblique' ) ); ?> </div> </a> <?php endif; add_action( 'oblique_link_to_single','custom_oblique_post_link_to_single', 1 );
