I figured it out. Sort of.
Here is what’s in the first template:
{exp:weblog:entries weblog="prod_container" dynamic="on" orderby="date" sort="desc" limit="15"}
<h1>{title}</h1>
{if prod_container_tagline}
<h2>{prod_container_tagline}</h2>
<p> {/if}<br />
<br />
{if prod_container_summary}<br />
<br />
{prod_container_summary}<br />
<br />
{/if}<br />
{embed="products/listings" issue="{related_entries id="prod_container_issue"}{entry_id}{/related_entries}" page="{prod_container_page}"}<br />
{/exp:weblog:entries}
And here is what is in the embedded template:
{exp:weblog:entries weblog="prod_listing" orderby="date" sort="asc"}
<?php
$listing_issue = "{related_entries id="prod_listing_issue"}{entry_id}{/related_entries}";
$container_issue = "{embed:issue}";
if ($listing_issue == $container_issue)
{
?>
{if prod_listing_page == "{embed:page}"}
<h3>{title}</h3>
<p>{prod_listing_des}<br />
{/if}</p>
<p><?php<br />
}<br />
?></p>
<p>{/exp:weblog:entries}
The new problem is if I add the URL Title to the URL string it’s displaying the info from the entry in the prod_container weblog but none of the entries from the embedded template pulling from prod_listing.
Does anyone have any ideas?
