Lookup row in matrix field by "Name" column?

Question

If I have a matrix field with 2 fields "Name" and "Entry" is it possible to lookup the first row in that matrix field which has a specific "Name"?

Context: Twig template.

Answer 1

According to this answer the only ways to filter matrix blocks are by type, or by position. So you need to use the if condition on the twig for tag.

{% for m in entry.myMatrix if m.theName == nameImLookingFor %}
  {% if loop.index == 1 %}
    got the first one, it is {{m.theName}}
  {% endif %}
{% endfor %}

If you don't want to loop over all of the blocks, you can also install the mnbreakandcontinue plugin and break out of the loop after the first match:

{% for m in entry.myMatrix if m.theName == nameImLookingFor %}
  got the first one, it is {{m.theName}}
  {% break %}
{% endfor %}
