SOLVED How to hook filter to component content?

[Bigin]

There is no such a hook exists. There is a function get_component(), but it is really useless because it does not return the component but processes it immediately (should normally be named "exec_component"). Don't waste your time on it, rather create a custom function/plugin instead.

You can execute your function on any action and alter the content of your component:

PHP Code:

add_action('theme-header', 'modify_component', array('your-component-slug')); 


And the function may look like this:

PHP Code:

function modify_component($id) {
    global $components;

    if(!$components) {
        $components = array();
        if(file_exists(GSDATAOTHERPATH.'components.xml')) {
            $data = getXML(GSDATAOTHERPATH.'components.xml');
            $components = $data->item;
        }
    }
    
    foreach($components as $component) {
        if($component->slug == $id) {
            $newValue = 'New component value';
            $component->value = $newValue;
        }
    }    
}
