Channel call inside channel call...

NEWBIE: I’m trying to do a channel call (exp:channel:entries) inside another channel call with out success.

This is because i’ve made a relation to choose a background image and some text about it.

But if the user havn’t chosen a background picture a random background image should replace it.

But i can’t make it work - are there an other way to the goal?
```
{exp:channel:entries channel="text"}

{title}

{if background == 0}
 {exp:channel:entries channel="background_photo" orderby="random" limit="1"}
  background-image: url({photo});
 {/exp:channel:entries}
{if:else}
 {related_entries id="Background"}
  background-image: url({photo});
 {/related_entries}
{/if}

{article_text}
```

Move your nested channel:entries loop into an embed and it will work. You cannot nest channel:entries tags within each other unless you embed the nested one.

Still not working - but it helped a little, but what I didn’t mention is that the background image and the following text are placed to different places in the HTML – the image in a style in the header and the following text in a div inside the body…

And then I need two embedded templates - but the random aint the same then 😕

...while writing this question im thinking about using embed variables…

{exp:channel:entries channel="text_article"}
<html>
<head>
<style>
body {
 padding: 0;
 margin: 0;
{if background == 0}
 {embed="includes/random_background" piece_name="Topper"}
{if:else}
 {related_entries id="Background"}
  background-image: url({photo});
 {/related_entries}
{/if} 
 background-position: top center; 
 background-repeat: no-repeat; 
 background-color: #333;
 background-attachment: fixed;
}
</style>
</head>

<body>

{title}

{if background == 0}
 {embed="includes/random_background" piece_name="Hest"}
{if:else}
 {related_entries id="Background"}

 <div id="infoleft">
        {ingredients}
        </div>
  
        <div id="inforight">
         
         <h3>{title}</h3>
<p>  {recipe_text}<br />
            <br />
        </div><br />
 <br />
 {/related_entries}<br />
{/if}</p>

<p></body><br />
</html><br />
{/exp:channel:entries}

and the embedded random_background template:

{exp:channel:entries channel="background_photo" orderby="random" limit="1"}

{if embed:piece_name == "Topper"}

background-image: url({photo});

{if:else}

<div id="infoleft">
 {ingredients}
</div>
  
<div id="inforight">
         
 <h3>{title}</h3>
<p> {recipe_text}<br />
            <br />
</div></p>

<p>{/if}</p>

<p>{/exp:channel:entries}

But this doesn’t work - any ideas?

Hi Hundred,

I have a couple of questions and a theory about why this may not be working. When you use the “id” parameter in your {related_entries} tag, that should be the “short_name” of the channel field you have assigned for relationships. Short names are typically lowercase and separated by underscores. In this case, I suspect the field’s short name is “background”? If you use the short name, does it properly pull your relationships?

My theory is that the brackets “{}” used in CSS are interfering with your ExpressionEngine tags. If you break this down to a simple test, excluding the CSS and just trying to embed a second simple template, are your conditionals processed?

Thanks!
