Hints Archives - MDTF - WordPress Meta Data Filter & Taxonomies Filter

Filtration for plugin “Content Views — Post Grid & List for WordPress”

To make MDTF compatible with plugin https://wordpress.org/plugins/content-views-query-and-display-post-page/ in file functions.php of your current wp theme add next code:

if (defined("PT_CV_PREFIX_")) {
    add_filter(PT_CV_PREFIX_ . 'query_params', function($args) {
        $args_filter = array();
        if (MetaDataFilter::is_page_mdf_data()) {

            do_shortcode('[meta_data_filter_results]');

MDTF hidden utilities

The plugin has hidden area: wp-admin/edit.php?post_type=meta_data_filter&page=mdf_utilities To display it: open index.php of the plugin (near row #33) find:

and uncomment it (remove ‘//’ on the beginning of the string) save the file you will find useful utility there ‘Terms to meta’ which allows convert any taxonomy terms slugs or names into meta data p.s. this… read more

CSS manipulations while search is going

When searching works in the redirect mode (not ajax) in tag <body> appears CSS class ‘mdf_search_is_going ‘. This fact can help you with any manipulations with site layout while MDTF search request is going on current page. For example hide smth:

body.mdf_search_is_going .any_container_class{
   display: none;
}

body.mdf_search_is_going .any_container_class{

display: none;

}

One hint how to avoid incompatibilities

Sometimes when MDTF works (searching going), some plugins have conflicts with it. Lets consider an example – one customer wrote me that his ‘membership plugin’ doesn work normally when MDTF making searching, there was some issues. So I suggested simple and quick decision: open index.php of that membership plugin for example (the same for another… read more

How to set logic ‘AND’ for taxonomies terms of the same taxonomy

This works for shortcode [mdf_custom custom_id=777] with attribute ‘custom_id’ (777 is in the code below) + doesn work with dynamic recount (you can hide count by CSS) Example: http://general.wp-filter.com/category/flowers-posts/ open your current wp theme functions.php file drop there next code:

//***
add_filter('mdf_custom_shortcode_query_args', 'mdf_custom_shortcode_query_args', 10, 2);

function mdf_custom_shortcode_query_args($args, $custom_id)
{
    $and_tax_relation = array('post_tag');
    //https://codex.wordpress.org/WordPress_Taxonomy
    if ($custom_id == '777')
    {
        $args['tax_query'] = mdf_modify_tax_query($args['tax_query'], $and_tax_relation);        
        //add_filter('mdf_dyn_tax_recount_args', 'mdf_dyn_tax_recount_args', 10, 1);
    }

    return $args;
}

//*** for dynamic recount
add_filter('mdf_dyn_tax_recount_args', 'mdf_dyn_tax_recount_args', 10, 1);

{
    $and_tax_relation = array('post_tag');
    return mdf_modify_tax_query($tax_query_array, $and_tax_relation);
}

How automatically enter the “meta_data_filter_cat” when an user inserts a new article

Meta filter category ID – keeps in each post with the same name key ‘meta_data_filter_cat’. So if you want to allow your user create new posts with already predefined or selected ‘Meta filter category ID’ you are need in your wp theme functions.php add next code:

add_action('save_post', 'my_save_post', 1);

function my_save_post() {
    if (!empty($_POST)) {
        global $post;
        if (is_object($post)) {
            $meta_data_filter_cat_id = 777;
            //$meta_data_filter_cat_id=$_POST['meta_data_filter_cat_id'];
            if ($post->post_type == '__your_post_type_slug_here__') {
                update_post_meta('meta_data_filter_cat', $meta_data_filter_cat_id);
            }
        }
    }
}

add_action('save_post', 'my_save_post', 1);

function my_save_post() {

if (!empty($_POST)) {

global $post;

if (is_object($post)) {

$meta_data_filter_cat_id = 777;

//$meta_data_filter_cat_id=$_POST['meta_data_filter_cat_id'];

if ($post->post_type == '__your_post_type_slug_here__') {
