Check if child entries exists

Question

I'm pulling in entries which are the descendant of the current entry id.

This is an example of my structure: Your Adventure > Honeymoon > A trip entry.

The below code is being used on the Honeymoon entry to list any trip entries that are children of the current page.

The below code is working fine apart from the if statement I'm wrapping it all in as I don't want any of the wrapping divs if there are no child pages within 'Honeymoon Trips'.

{% if entry in craft.entries.section('yourAdventures').descendantOf(entry.id)  %}
<!-- This is wrong -->

<div class="section bg-pattern">
    <div class="inner">
         <div class="col-24 gutter-bottom--half ">
            <h3>Available {{ entry.title }}</h3>
            {% for entry in craft.entries.section('yourAdventures').descendantOf( entry.id).find() %}

            ...

            {% endfor %}
        </div>
    </div>
</div>

{% endif %}

Answer 1

If I figured out correctly what you want to do - this should do the trick:

{% if entry.children | length  %}

    <div class="section bg-pattern">
        <div class="inner">
             <div class="col-24 gutter-bottom--half">

                <h3>Available {{ entry.title }}</h3>

                {% for child in entry.children %}
                    <p>{{ child.title }}</p>
                {% endfor %}

            </div>
        </div>
    </div>

{% endif %}

entry.children is an alias for entry.getDescendants(1) which returns ElementCriteriaModel

Answer 2

Found a solution, I needed: {% if entry.hasDescendants() %}

{% if entry.hasDescendants() %}

    <div class="section bg-pattern">
        <div class="inner">
            <div class="col-24 gutter-bottom--half ">
                <h3>Available {{ entry.title }}</h3>

                {% for entry in craft.entries.section('yourAdventures').descendantOf( entry.id).find() %}

                    ...

                {% endfor %}
            </div>
        </div>
    </div>

{% endif %}
