Dialogs Feature: Tags (Keywords)

Updated: 21 Apr 2023


 

  • populate the Keywords List (Setup) with appropriate Tags or Keywords
    NOTE: Dialogs v.8 doesn't ship with a Keywords list, but it is very easily added. Just create a list named C_keywords, and enter your values. No additional fields are usually needed.
  • add an LRP field to more than one Dialogs List
  • populate the Keywords LRP for individual list items (content) on BOTH Lists (often, one of the Lists is the Pages List)
  • add the following function to /inc/custom_functions.inc.php 
    ///////////////////////////////////////////////////////////
// BUILD_LRP_WHERE
///////////////////////////////////////////////////////////
function build_LRP_where($field_name,$field_values) {
	$sql_where = '';
	$field_value_array = myExplode(',',$field_values,'|');
	foreach($field_value_array as $field_value) {
		if($sql_where) {
			$sql_where .= ' OR ';
		} else {
			$sql_where = ' (';
		}
		$sql_where .= "$field_name LIKE '%|" . addslashes($field_value) . "|%'";
	}
	if($sql_where) {
		$sql_where .= ' )';
	}
	return $sql_where;
}
  • create a List Template to show related content
  • call the List Template from within a Page Template or (detail) List Template specifying the WHERE clause: 
    // This would go in a page template
$whereclause="item_active=1 AND " . build_LRP_where('keywords',$this->db_page_row[keywords]);
$this->Show_List('list_related_studies.', array('view_where'=>$whereclause)); 

// This is how you would use it in a list template
$whereclause="item_active=1 AND " . build_LRP_where('keywords',$row[keywords]);

// when searching items on the SAME list, exclude the detail you're viewing
$this->Show_List('list_related_articles.', array('view_where'=>
   'item_id !='  . $row[item_id] . ' AND ' . $whereclause)); 

//when searching other Lists, just use $whereclause built above
$this->Show_List('list_related_studies.', array('view_where'=>$whereclause));
  • Create a page using the Page Template or calling the List Template with the defined Show_List
