Add shortcode name for enable shortcode_atts filter

Hi there!

I don’t mind adding this modification to the plugin, but I’m curious though: why do you need this?

A lot of people want to use shortcode for get post with the current category which your great plugin can’t do now.

there is a guy that propose a solution for that : https://blog.eexit.net/php-wordpress-popular-posts-for-the-current-category/

But use a lot of resources for nothing.

I think the best pratrice is to add an option to the shortcode:
[wpp cat=”current”]

and just add this code in the function.php

function sc_wpp_set_current_category( $out, $pairs, $atts ) {

if ( is_category() ) {
   $catID = get_query_var('cat');
   if (array_key_exists("cat",$atts)) {
      if ($atts['cat'] == "current"){
         $atts['cat'] = $catID;
        }
     }
  }
$out['cat'] = $atts['cat'];
return $out;
}

add_filter( 'shortcode_atts_wpp', 'sc_wpp_set_current_category', 1, 3 );

but in the core of wordpress (shortcodes.php)
the filter can’t call, if the function shortcode_atts don’t give the shortcode name :

/**
 * Combine user attributes with known attributes and fill in defaults when needed.
 *
 * The pairs should be considered to be all of the attributes which are
 * supported by the caller and given as a list. The returned attributes will
 * only contain the attributes in the $pairs list.
 *
 * If the $atts list has unsupported attributes, then they will be ignored and
 * removed from the final returned list.
 *
 * @since 2.5.0
 *
 * @param array  $pairs     Entire list of supported attributes and their defaults.
 * @param array  $atts      User defined attributes in shortcode tag.
 * @param string $shortcode Optional. The name of the shortcode, provided for context to enable filtering
 * @return array Combined and filtered attribute list.
 */
function shortcode_atts( $pairs, $atts, $shortcode = '' ) {
	$atts = (array)$atts;
	$out = array();
	foreach ($pairs as $name => $default) {
		if ( array_key_exists($name, $atts) )
			$out[$name] = $atts[$name];
		else
			$out[$name] = $default;
	}
	/**
	 * Filter a shortcode's default attributes.
	 *
	 * If the third parameter of the shortcode_atts() function is present then this filter is available.
	 * The third parameter, $shortcode, is the name of the shortcode.
	 *
	 * @since 3.6.0
	 * @since 4.4.0 Added the <code>$shortcode</code> parameter.
	 *
	 * @param array  $out       The output array of shortcode attributes.
	 * @param array  $pairs     The supported attributes and their defaults.
	 * @param array  $atts      The user defined shortcode attributes.
	 * @param string $shortcode The shortcode name.
	 */

	if ( $shortcode ) {
		$out = apply_filters( "shortcode_atts_{$shortcode}", $out, $pairs, $atts, $shortcode );
	}

	return $out;
}

Understood, thanks for the explanation ??

I’ll add the “wpp” part into the shortcode_atts function on the next release so you can hook into it without having to hack the code.

thank you very much ??
