I am trying to change the default landing state of a page from ‘all’ to a sepcific category or value. (i.e education) I am using a shortcode and am customising the php file. I am using a custom field of ‘projects’ and filtering these using a checkbox filter by ‘project-type’ (eg. education, commercial etc.)

Reading through the forum I think I need to use a combination of these three snippets but cannot put them together. Can anyone help out?

1.

function filter_function_name($input_object, $sfid)
{
if($input_object[‘name’]==’_sft_project-type’)||($input_object[‘type’]!=’select’))
{
//udpate this field before rendering
}

return $input_object;
}
add_filter(‘sf_input_object_pre’, ‘filter_function_name’, 10, 2);

2.

$input_object[‘defaults’] = array(“education”);

3.

//Get an array of objects containing data for the current search/filter
//replace 1526 with the ID of your search form
global $searchandfilter;
$sf_current_query = $searchandfilter->get(43)->current_query();
echo $sf_current_query->is_filtered();
