    Hello guys,

    I'm using a shortcode that helps me get posts from my blog. So for example on my home page, I would type [mpc_recent_posts number="10"] and it would make 10 recent posts from blog appear on my home page.
    What I want to do is to get posts from some category, f.e. announcements.

    How can I do that?

    Here's the original shortcode:

    /*-----------------------------------------------------------------------------------*/
    /*	X. Recent Posts
    /*-----------------------------------------------------------------------------------*/
    
    function mpc_recent_posts($atts, $content = null) {
    	extract(shortcode_atts(array(
        'number' => '4',
        'post' => ''
        ), $atts));
    
    	global $page_id;
    
    	$mp_option = gentle_get_global_options();
    
    	$sidebar_position = '';
    
    	if(isset($mp_option['gentle_sidebar']) && isset($mp_option['gentle_sidebar']['radio_sb_' .$page_id])) {
    		$sidebar_position = $mp_option['gentle_sidebar']['radio_sb_' .$page_id];
    	} 
    
    	if($sidebar_position == '')
    		$sidebar_position = 'right';
    
    	$scroll = 1;
    	if($sidebar_position == 'none')
    		$scroll = 2;
    
        ?>
    
        <?php
    	$return = '';
    
    	$tags = wp_get_post_tags($post);
    
        if($tags != '') {
        	$tag_ids = array();
    		foreach($tags as $individual_tag) {
    			$tag_ids[] = $individual_tag->term_id;
    		}
    
        $query = new WP_Query(array(
        		'post_type' => 'post',
        		'showposts' => $number,
         		'tag__in' => $tag_ids,
    			'post__not_in' => array($post)
        		));
    	} else {
    		$query = new WP_Query(array(
        		'post_type' => 'post',
        		'showposts' => $number
        		));
    	}

    You should add a param to the shortcode call, deciding if that is a category string or a category id. So the user calls it:

    [mpc_recent_posts number="10" category="software"]

    That must be referenced on the shortcode_atts.

    Then you should fetch the category (from string or id) and pass it to the WP_Query (as category_name for string, or cat for id).

    Is there a much easier method for this?
