I'd like to display two lists of events : one list with events created by organizers with organizer status and a list with events created by organizers with member status. My conditions are like this : "if some event exist" and "if the organizer who created the event is an organizer (or a regular member)". For information, "organizer" and "member" depend on the status of the organizer. Because of the second condition, I had this error :

Key "organizer" for array with keys "0" does not exist.

I don't understand why... What needs to be corrected ?

Thank you very much for your help.

My twig file :

{% extends 'base.html.twig' %}

{% block title %}Liste des activités{% endblock %}

CodePudding user response：

In your case, you can have many Events, so in your twig, you need to use a for loop. Place your for loop before the if.

Something like this :

<ul >

{% for event in events %}

    {% if event and event.organizer.status == 'organizer' %}

        <a >
            <img src="{{ asset('img/flag_images/' ~ event.spokenlanguage.image) }}" alt="Drapeau {{ event.spokenlanguage.name }}" > {{ event.title }}
        </a>


    {% else %}

        <p>Il n'y a pas de zpeak sortie organisée.</p>

    {% endif %}

 {% endfor %}

</ul>

In case you are sure to have only one item, you can use events[0].organizer.status == 'organizer'
