optional parameters of "component"

[Zegnåt]

@mvlcek:

I see you are using a global variable inside your implementation, why? You can do this without leaking any data into the global scoop, that way you don’t have to bother with back-upping any already existing variables either.

This works just as well: (large bit of code directly from the GS core)

Code:

function get_component_args($id) {
    if (func_num_args() > 1) { $args = func_get_args(); array_shift($args); }
    if (file_exists(GSDATAOTHERPATH.'components.xml')) {
        $data = getXML(GSDATAOTHERPATH.'components.xml');
        $components = $data->item;
        if (count($components) != 0) {
            foreach ($components as $component) {
                if ($id == $component->slug) {
                    eval("?>" . strip_decode($component->value) . "<?php ");
                }
            }
        }
    }
}

And can be used like this, in a template:

Code:

get_component_args('credits','Zegnåt','http://zegnat.net/');

and with a component called credits:

Code:

<p>Build by <a href="<?php echo $args[1]; ?>"><?php echo $args[0]; ?></a></p>

Please stay out of the global scoop unless you need to communicate with global data.

The big question for this topic to answer is: should this be implemented in the core?
