Access function argument in different function?

I have this function:

<?php myWidget() { ?>

         <div id="<?php echo $args['widget_id']; ?>">
              <p>Something</p>
         </div>

    <?php } ?>

(widget_id is Wordpress core function so I have no direct access to that, it just simply generates widgets name)

I wanted to 开发者_JS百科add my widget as a shortcode so needed to create another function:

function myWidget_shortcode( $atts ) {
        extract( shortcode_atts( array(
        /* attributes here */
        ), $atts ) );

        ob_start();    
        the_widget(myWidget);
        return ob_get_clean();
}    

the_widget just simply calls widget called myWidget.

The point is, everything works good, but id=" " is always empty when I use the second code.

I know it's a Wordpress question, but I believe this has more to do with my PHP code.

Any ideas?

Judging from your last comment the problem is that $args is not set and since the ID is set from $args it will "".

You have to find out where $args is set and either make sure that part is run or set it your self.

$args in this case is not arguments to myWidget method but a global array.

Check if it exists at all

isset($args)

My guess is its a scope issue. $args isnt inside the function. Try passing it to the function
