<h4>Template Syntax: a quick guide for WordPress Front End for Custom Field</h4>
<p>Note: <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">WordPress Classic Editor</a> is preferred to edit templates</p>
<h4>Comments</h4>
<ul>
<li>Use <code>{# comments #}</code> for comments, and comments will not render to the user,</li>
</ul>
<h4>Variables output</h4>
<p>Variables in templets are post title, post object, and custom fields. To output post title you can use <code>{{ title }}</code>. If your post has a custom field called price. We use <code>{{ price }}</code> to output the price. Use a dot (.) to access attributes of a variable (methods or properties of an object, or items of an array: <code>{{ foo.bar }}</code></p>
<h4>Conditional output</h4>
<p>The <code>if</code> statement in Twig check if a variable has a value or an expression evaluates to <code>true</code> 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</p>
<pre>{% if agent %}
    We have an agent in your area
    Our agent: {{ agent }}
{% endif %}</pre>
<p>another example; let’s say that we have a field named price. We want to display a text if the price is zero</p>
<pre>{% if price == 0 %}
   <p>This product is free</p>
{% endif %}
</pre>
<p>Please note that we use the operator <code>==</code> to check the equality You can also test if an array is not empty:</p>
<pre>{% if meanings %}
   <p>The array or repeater field **meaning** contains some values</p>
{% endif %}</pre>
<h4>Closing condition block</h4>
<p>Always use <code>{% endif %}</code> to close the previous if condition, Read more about <a href="https://twig.symfony.com/doc/3.x/tags/if.html" rel="nofollow ugc">if keyword in twig</a></p>
<h4>Repeater field and arrays</h4>
<p>If our field or variable is an array or a repeater field we can loop over each item in a sequence using for keyword</p>
<p>The for statement code example</p>
<pre>{% for m in meanings %}
   Meaning: {{ m.meaning }}
{% endfor %}</pre>
<p>The for statement format</p>
<ul>
<li>We use  <code>{% for m in meanings %}</code> to loop over an array or repeater field called <code>meanings</code> using <strong><code>m</code></strong> to mention for each row</li>
<li>Inside the loop starts the subfields or array items with the variable name <code>**m.**</code></li>
<li>Always close the loop use <code>{% endfor %}</code></li>
<li>Read more about <a href="https://twig.symfony.com/doc/3.x/tags/for.html" rel="nofollow ugc">the <code>for</code> keyword in twig</a></li>
</ul>
<h4>Important notes for templates code</h4>
<ul>
<li>In WordPress classic editor show source and ensure there are no tags inside the template code; ex <code>{% <del><span></del> endfor <del></span></del> %}</code></li>
<li>For more details, see: <a href="https://twig.symfony.com/doc/2.x/" rel="nofollow ugc">https://twig.symfony.com/doc/2.x/</a></li>
</ul>
<h4>Power templating with only 4 keyword</h4>
<p>Using <code>if, endif, for and endfor</code> allows to generate a powerful template; however, twig contains many other useful keywords to see other keyword and how to use them visit <a href="https://twig.symfony.com/doc/2.x/" rel="nofollow ugc">twig documentation</a></p>
<h4>Short template example</h4>
<pre><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 %}
</pre>
<h4>Output post data</h4>
<p>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 <code>post.content</code> to access post content</p>
<pre>{{ post.title }}
   
{{ post.content }}
</pre>

<h4>Why templating engine and not a raw PHP programming language</h4>
<ul>
<li>More Simple; so templating is more readable, and very easy that allows users to learn quickly,</li>
