I must connect custom publish types posts that are items using the standard wordpress posts. Can anybody point me within the right direction how to do this?

It is because is i wish to write blog articles plus some of my blog articles may connect with a particular product. The like the items page i wish to have the ability to possess a link of related articles to that particular product.

I recommend in order to save an assortment or string from the IDs of related posts / related product as utilizing a custom area within the after sales of the Website.

Around the frontend of the Website you will get the connected IDs in the Database making Links while using functions <?php echo get_the_title(ID); ?> and <?php echo get_page_link(ID); ?>.

For the way comfortable the after sales is always to edit, you can include custom Meta Boxes towards the after sales, while using following code in functions.php.

add_action('admin_init', 'register_meta');
add_action('save_post', 'save_metadaten');

function register_meta(){
        add_meta_box("produkt_meta","Daten des Produkts","produkt_meta","produkt","normal","high");

function produkt_meta() {
    global $post;
    $custom = get_post_custom($post->ID);
    $preis = $custom["produkt_preis"][0]; ?>

    <p style="padding-bottom:4px;"><label style="width:200px; display:inline-block;">Preis:</label><input size="5" name="produkt_preis" value="<?php echo $preis; ?>" /> €</p>

function save_metadaten(){
    global $post;

    // check if there are associated post IDs set somehow, and prepare these to save them in the database

    if($_POST["produkt_preis"]) {update_post_meta($post->ID, "produkt_preis", $_POST["produkt_preis"]);}

Replace "produkt_preis" with "connected_publish_ids" or whatever.

For optimum comfort you can include a JavaScript towards the produkt_meta function which lists you which means you simply click it and also the meta-area is instantly filled, but this is actually the part you need to create by yourself now -)

Hope this can help.
