First of all, thanks picandocodigo for the great plugin!
With a few modifications I achieved a way to list posts that belong to two or more categories. Here's my solution:
In the shortcode, use + instead of the comma to separate category IDs or names, like this:
[catlist id=3+4] or [catlist name=sports+baseball] will list only posts that belong to both categories.
You'll need to make the following modifications in the CatList.php file, inside the include folder.
IMPORTANT - the changes proposed below are for the version 0.28 of the plugin. Make a backup copy of the original files!
Locate this: (line 29 in the original file)
$args = array('cat'=> $this->lcp_category_id);And change to:
if (is_array($this->lcp_category_id))
$args = array('category__and' => $this->lcp_category_id);
else
$args = array('cat'=> $this->lcp_category_id);Replace the function get_lcp_category() (lines 113-137 in the original file) for this:
private function get_lcp_category(){
if ( isset($this->params['categorypage']) &&
$this->params['categorypage'] == 'yes' ):
$this->lcp_category_id = $this->lcp_get_current_category();
elseif ( !empty($this->params['name']) ):
if (preg_match('/\+/', $this->params['name'])):
$categories = array();
$cat_array = explode("+", $this->params['name']);
foreach ($cat_array as $category) :
$id = $this->get_category_id_by_name($category);
$categories[] = $id;
endforeach;
$this->lcp_category_id = $categories;
elseif (preg_match('/,/', $this->params['name'])):
$categories = '';
$cat_array = explode(",", $this->params['name']);
foreach ($cat_array as $category) :
$id = $this->get_category_id_by_name($category);
$categories .= $id . ",";
endforeach;
$this->lcp_category_id = $categories;
else:
$this->lcp_category_id = $this->get_category_id_by_name($this->params['name']);
endif;
elseif ( isset($this->params['id']) && $this->params['id'] != '0' ):
if (preg_match('/\+/', $this->params['id']))
$this->lcp_category_id = explode("+", $this->params['id']);
else
$this->lcp_category_id = $this->params['id'];
endif;
}
