* Hi Scribu,
Now I’m trying to get the arbitrary value that I insert in the connection
information array from outside the loop. I have looked at Twansparant question
and looked at the github code but the answer escapes me. My code is for functions.
php:
* ```
$my_connection_type = p2p_register_connection_type( array(
'from' => 'product',
'to' => 'client',
'fields' => array(
'product_link' => 'link'
)
)
);
```
* and in the page:
* ```
'client',
'client_type' => 'Distributor'));
echo '' . _e('Where to buy', 'eq_power') . '
';
while ($wp_query->have_posts() ) : $wp_query->the_post();
echo p2p_get_meta($post->p2p_id, 'product_link', true);
endwhile;
wp_reset_postdata();
?>
```
* thanks

* First of all, does the product link change depending on which client the product
is connected to? If not, it should be a normal product custom field:

* Yes. The idea being that the link is a placeholder for our product at the distributor’s
website. The first part of the link does not change, but the last part, the part
associated with the product id does.
* Thanks again

* Ok, then p2p_get_meta() doesn’t work because your WP_Query isn’t connecting any
products. It just gets a list of clients.
* Assuming the code is run on `single-product.php`, try using:
* ```
$wp_query = $my_connection_type->get_connected( get_queried_object_id(), array(
'client_type' => 'Distributor'
);
```
* Otherwise, you’ll have to replace `get_queried_object_id()` with whatever product
id you want to connect.

* Hi Scribu,
I have finally have been able to come back to this. However, for
the life of me I can’t make it to work. The page is single-product, I the client
type is a custom post with ‘distributor’ as taxonomy type.
* I have turned debug on and I get:
Notice: Undefined variable: my_connection_type
* Even if I have in the function.php ‘global $my_connection_type’
* Using version 1.0
* thanks,
* mauro

* Try using a connection type id, as described here:

* Thanks, now it works. Here is the code:
* In the functions.php I have included the id:
* ```
function my_connection_types() {
// Make sure the Posts 2 Posts plugin is active.
if ( !function_exists( 'p2p_register_connection_type' ) )
p2p_register_connection_type( array(
'id'=>'product_id_link',
'from' => 'product',
'to' => 'client',
'fields' => array(
'product_link' => 'link'
)
)
);
}
add_action('init', 'my_connection_types', 100);
```
* in the single-product.php page I have (in php tags):
* ```
$wp_query = p2p_type( 'product_id_link' )->get_connected( get_queried_object_id(), array(
'client_type' => 'Distributor'));
echo '' . _e('Where to buy', 'eq_power') . '
';
while ($wp_query->have_posts() ) : $wp_query->the_post();
echo p2p_get_meta($post->p2p_id, 'product_link', true);
endwhile;
wp_reset_postdata();
```
* I hope this is of help for someone.
