Template Syntax: a quick guide for WordPress Front End for Custom Field

Note: WordPress Classic Editor is preferred to edit templates


  • Use {# comments #} for comments, and comments will not render to the user,

Variables output

Variables in templets are post title, post object, and custom fields. To output post title you can use {{ title }}. If your post has a custom field called price. We use {{ price }} to output the price. Use a dot (.) to access attributes of a variable (methods or properties of an object, or items of an array: {{ }}

Conditional output

The if statement in Twig check if a variable has a value or an expression evaluates to true We can add conditions to display any text. Let’s say that we have a custom field named “agent” and want to display a text when the field agent contains a text. We can write

{% if agent %}
    We have an agent in your area
    Our agent: {{ agent }}
{% endif %}

another example; let’s say that we have a field named price. We want to display a text if the price is zero

{% if price == 0 %}
   <p>This product is free</p>
{% endif %}

Please note that we use the operator == to check the equality You can also test if an array is not empty:

{% if meanings %}
   <p>The array or repeater field **meaning** contains some values</p>
{% endif %}

Closing condition block

Always use {% endif %} to close the previous if condition, Read more about if keyword in twig

Repeater field and arrays

If our field or variable is an array or a repeater field we can loop over each item in a sequence using for keyword

The for statement code example

{% for m in meanings %}
   Meaning: {{ m.meaning }}
{% endfor %}

The for statement format

  • We use  {% for m in meanings %} to loop over an array or repeater field called meanings using m to mention for each row
  • Inside the loop starts the subfields or array items with the variable name **m.**
  • Always close the loop use {% endfor %}
  • Read more about the for keyword in twig

Important notes for templates code

  • In WordPress classic editor show source and ensure there are no tags inside the template code; ex {% <del><span></del> endfor <del></span></del> %}
  • For more details, see:

Power templating with only 4 keyword

Using if, endif, for and endfor allows to generate a powerful template; however, twig contains many other useful keywords to see other keyword and how to use them visit twig documentation

Short template example

<h2>Meaning of {{ title }}</h2>
{# This is a comment and will not render #}
{% for m in meanings %}
    {% if m.meaning %}
        Meaning: {{ row.meaning }}
    {% endif %}
    {% if m.example %}
        Example: {{ m.example }}
    {% endif %}
{% endfor %}

Output post data

We can access the post using the post keyword. to access any property of the post we put a dot (.)  and then we put the property name for example use post.content to access post content

{{ post.title }}
{{ post.content }}
