I have a custom plugin that was written by someone, I can't reach anymore. It has a search option, that produces a table with seminars in different cities.
Right now I can have a query with this shortcode:
[kurssuche class="course_search" place="1"]
that shows a table with all seminars in the city "1". How can I produce a table which shows seminars for two or more cities?
I'm new to this, any help is much apprechiated!
This is the code:
if(isset($_REQUEST['search']) || $atts['place']!='')
{
if(isset($_REQUEST['city']) && $_REQUEST['city'])
{
$where[] = "city = '".$_REQUEST['city']."'";
}
else if($atts['place'] && $_REQUEST['city']!=='0')
{
$where[] = "city = '".$atts['place']."'";
}
$courseplanList = $wpdb->get_results($query);
}
}
