Get image from related entries asset field

Question

I have a "single" entry which has a "entries" field. The related entries have a image field of the "Assets" type.

In the template, i want to display the image from each of the related entries. I figured i could do the following

        {% for relatedImage in entry.relatedImages %}
            {% for images in relatedImage %}
                <div><img src="{{ images.url }}" alt="{{ asset.title }}" /></div>
            {% endfor %}
        {% endfor %}

Though not only does it not work, but it is probably pretty inefficient too. Whilst I'm here, how do people go about inspecting what you get from your vars? Is there a Twig/Craft equivalent to PHP's var_dump('relatedImage')?!

Any ideas most welcome!

Answer 1

Got a solution that is cleaner than nested for loops.

{% set myRelatedImage = entry.relatedImages.first %}

then I can do

<img src='{{ myRelatedImage.images.first.url }}'>

My use case was slightly different. I have a bunch of sermons entries that are related to a series entry. It's the series entry that has the image attached.

This worked very nicely.

Answer 2

I am an idiot, i just misspelled things. I'm still interested to know a more efficient way to do this though?

Corrected code:

            {% for relatedImage in entry.relatedImages %}
                {% for images in relatedImage.image %}
                    <div><a href="{{ relatedImage.url }}"><img src="{{ images.url }}" alt="{{ relatedImage.title }}" /></a></div>
                {% endfor %}
            {% endfor %}

And the debug would be {{ dump(relatedImage) }}

You could use Craft's relations API and try something like this:

{% set assets = craft.assets.relatedTo(entry.relatedEntries) %}

However, one thing I have noticed with this approach is that it does not return duplicate images. For example, lets say you have two related entries in your single's entries field, and each of those entries have the same image, it will only return the image once. This could be either positive or negative depending on what you want to do with the data.
