Loop through fields of a matrix block

Question

I have a matrix field shaped as follows:

• MatrixField
  • Block ( just 1 blocktype )
    • Field1
    • Field2
    • Field3
    • Field4
    • FieldN

I want to loop through all the fields inside a block, check if the field is set and other stuff. How can I do it?

Answer 1

1. Check if the matrixField is populated:

   {% if entry.matrixField|length %}{% endif %}

2. There are two options to pull out fields from a block type.

   Option A: use a for-loop pointed at your Matrix field

   // If you want to output block of a certain type
   {% if entry.matrixField|length %} 
       {% for block in entry.matrixField.type('yourBlock') %}
           {{ block.field1 }}
           {{ block.field2 }}
           {{ block.fieldN }}
       {% endfor %}
   {% endif %}
   
   // OR multiple types
   {% if entry.matrixField|length %} 
       {% for block in entry.matrixField %}
           {% if block.type == "yourBlock" %}
               {{ block.field1 }}
               {{ block.field2 }}
               {{ block.fieldN }}
           {% elseif block.type == "yourBlock1" %}
               {{ block.field1 }}
               {{ block.field2 }}
               {{ block.fieldN }}
           {% endif %}
       {% endfor %}
   {% endif %}
   

   Option B: use simplified method of a for-loop

   {% if entry.matrixField|length %} 
       {% set yourBlock = entry.matrixField.type('yourBlock') %}
       {% for block in entry.matrixField %}
           {% switch block.type %}
               {% case "yourBlock" %}
                   {{ block.field1 }}
                   {{ block.field2 }}
                   {{ block.fieldN }}
           {% endswitch %}
       {% endfor %}
   {% endif %}
