Override HTML output from a function

    Good Morning!

    I would like to figure out how I can edit, via the functions.php of my ChilTheme, the HTML code generated by a function of the thema.

    I have this code:

    function crumina_social_icons()
{
    global $one_touch_option;

    if (!$one_touch_option['expand_social_icons']){
        $class="closed";
    } else {
        $class="opened";
    }
	if ($one_touch_option['soc_ico_panel']) :

    echo '
    <div class="row"><div class="large-12 columns">
    <div id="panel">

        <a id="open-social-button" href="#">
            <i class="linecon-globe"></i>
            <span class="desc">' . __('Pagine SOCIAL', 'crum') . '</span>
            <span>' . __('GDP', 'crum') . '</span>
        </a>
        <div id="soc-icons-wrap" class="' . $class . '">';

            crum_social_networks();

        echo '</div>
    </div>
    </div></div>';

	endif;
}

add_action('reactor_header_after', 'crumina_social_icons', 2);

    I was trying to create a function like:
    add_filter('reactor_header_after', 'crumina_social_icons_custom');
    to replace the text “Pages SOCIAL” or other …

    How should I proceed?

    Thanks.

    you cant filter an action..

    you need to remove the action and replace it with your own so something like this…

    <?php 

// Deregister original function and register replacement
function switch_crumina_social_icons()
{
	remove_action('reactor_header_after', 'crumina_social_icons', 2);
	add_action('reactor_header_after', 'my_crumina_social_icons', 2);
}
add_action('after_setup_theme', 'switch_crumina_social_icons');

/* NB. this is tricky but this action need to hook after the function
 * is original registered but before it is executed otherwise it will miss it.
 * 'after_setup_theme' should be about right.
 */

// Replacement function
function my_crumina_social_icons()
{
	# copy original code... here
	....
	# change as required.
}

?>

    Hi geraintp,
    thanks for your support, but this solution doesn’t work.

    If you see this screenshot, this hook generates a duplicate where the first row is created by the new functions and the second from the default.

    Maybe I must change ‘reactor_header_after’ with another $hook?

    Thanks.

    Hi ok,

    basically were hooking in too early, so the initial action hasn’t been added before we’ve tried to replace it.

    try changing

    add_action('after_setup_theme', 'switch_crumina_social_icons');

    to

    add_action('init', 'switch_crumina_social_icons');

or

add_action('wp_loaded', 'switch_crumina_social_icons');

    Hi geraintp,
    I resolved with your solution:

    function switch_crumina_social_icons()
{
	remove_action('reactor_header_after', 'crumina_social_icons', 2);
	add_action('reactor_header_after', 'my_crumina_social_icons', 2);
}
add_action('init', 'switch_crumina_social_icons');

    Thanks for your support!
