# ACF

The following directives are for use with Advanced Custom Fields. If ACF is not installed and activated, they will not be initialized.

# @field

@field echo's the specified field using get_field().

@field('text')

To echo a field for a specific post, you can pass a post ID as a second parameter:

@field('text', 1)

If the field you are echoing is an array, you can pass the array key as a second parameter:

@field('image', 'url')

To echo a field for a specific post that is also an array, you can pass the post ID as a third parameter:

@field('image', 'url', 1)

# @hasfield

@hasfield is a simple conditional checking if the specified field exists and is not empty. It can be closed using @endfield.

@hasfield('list')
  <ul>
    @fields('list')
      <li>@sub('item')</li>
    @endfields
  </ul>
@endfield

To check the existance of a field for a specific post, you can pass a post ID as a second parameter:

@hasfield('list', 5)
  <ul>
    @fields('list', 5)
      <li>@sub('item')</li>
    @endfield
  </ul>
@endfield

If the field you are checking against is an array, you can pass the array key as a second parameter:

@hasfield('image', 'url')
  <figure class="image">
    <img src="@field('image', 'url')" alt="@field('image', 'alt')" />
  </figure>
@endfield

To check the existance of a field that is an array for a specific post, you can pass the array key as a second parameter and the post ID as a third parameter:

@hasfield('image', 'url', 1)
  <figure class="image">
    <img src="@field('image', 'url', 1)" alt="@field('image', 'alt', 1)" />
  </figure>
@endfield

# @isfield

@isfield is a simple conditional for checking if your field value equals a specified value. It can be closed using @endfield.

@isfield('cta_type', 'phone')
  <i class="fas fa-phone"></i>
@endfield

To check the field value of a specific post, you can pass a post ID as a third parameter:

@isfield('cta_type', 'phone', 1)
  <i class="fas fa-phone"></i>
@endfield

If the field you are checking against is an array, you can pass the array key as a second parameter and the value you are checking against as a third parameter:

@isfield('cta', 'type', 'phone')
  <i class="fas fa-phone"></i>
@endfield

To check the field value of a field that is an array for a specific post, you can pass the array key as a second parameter, the value you are checking against as a third parameter, and the post ID as a fourth parameter:

@isfield('cta', 'type', 'phone', 1)
  <i class="fas fa-phone"></i>
@endfield

# @fields

@fields acts as a helper for handling repeater fields. It is wrapped with a have_rows() conditional, and if it exists and is not empty, begins the while loop followed by the_row(). It can be closed using @endfields.

<ul>
  @fields('list')
    <li>@sub('item')</li>
  @endfields
</ul>

To retrieve fields for a specific post, you can pass a post ID as a second parameter:

<ul>
  @fields('list', 1)
    <li>@sub('item')</li>
  @endfields
</ul>

# @sub

@sub echo's the specified sub field using get_sub_field(). It is to be used inside of repeatable fields such as @fields, @layout, @group, and @options.

<ul>
  @fields('list')
    <li>@sub('item')</li>
  @endfields
</ul>

If the sub field is an array, you can pass the key(s) as additional parameters:

<ul class="slider">
  @fields('slides')
    <li class="slide">
      <img src="@sub('image', 'url')" alt="@sub('image', 'alt')" />
    </li>
  @endfields
</ul>
<ul class="slider">
  @fields('slides')
    <li class="slide">
      <img src="@sub('image', 'sizes', 'thumbnail')" alt="@sub('image', 'alt')" />
    </li>
  @endfields
</ul>

More usage of @sub can be found alongside the examples of the repeatable fields listed above.

# @hassub

@hassub is a simple conditional checking if the specified field exists and is not empty. It can be closed using @endsub.

@hassub('icon')
  <i class="fas fa-@sub('icon')"></i>
@endsub

If the sub field you are checking against is an array, you can pass the key(s) as additional parameters:

@hassub('image', 'url')
  <img src="@sub('image', 'url')" alt="@sub('image', 'alt')" />
@endsub
@hassub('image', 'sizes', 'thumbnail')
  <img src="@sub('image', 'sizes', 'thumbnail')" alt="@sub('image', 'alt')" />
@endsub

# @issub

@issub is a simple conditional for checking if your sub field equals a specified value. It can be closed using @endsub.

@issub('icon', 'arrow')
  <i class="fas fa-arrow-up fa-rotate-90"></i>
@endsub

If the sub field you are checking against is an array, you can pass the array key as a second parameter and the value you are checking against as a third parameter:

@issub('icon', 'name', 'arrow')
  <i class="fas fa-@sub('icon', 'value') fa-rotate-90"></i>
@endsub

# @layouts

@layouts acts as a helper for handling flexible content fields. Under the hood, it is essentially the exact same as @fields, but is provided to allow for a more clean, readable code-base in conjunction with @layout which calls get_row_layout(). It can be closed using @endlayouts.

@layouts('components')
  [...]
@endlayouts

To retrieve layouts for a specific post, you can pass a post ID as a second parameter:

@layouts('components', 1)
  [...]
@endlayouts

# @layout

@layout serves as a conditional checking if get_row_layout() equals the specified value during the have_rows() while loop.

Using @layouts, this allows you to have a rather clean view when displaying your flexible content components. It can be closed using @endlayout.

@layouts('components')
  @layout('card')
    <div class="card">
      @hassub('image')
        <div class="card-image">
          <img src="@sub('image', 'url')" alt="@sub('image', 'alt')" />
        </div>
      @endsub

      <div class="card-content">
        <h2>@sub('title')</h2>
        @sub('description')
      </div>
    </div>
  @endlayout

  @layout('button')
    @hassub('url')
      <a href="@sub('url')" class="button button--@sub('color') button--@sub('size')">
        @hassub('icon')
          <i class="fa fa-@sub('icon')"></i>
        @endsub
        <span>@sub('label')</span>
      </a>
    @endsub
  @endlayout

  @layout('content')
    @hassub('content')
      <div class="content">
        @sub('content')
      </div>
    @endsub
  @endlayout
@endlayouts

# @group

@group acts as a helper for handling grouped fields. Under the hood, it is essentially the exact same as @fields and thus serves as a simple alias for code readability purposes. Which one you prefer is entirely up to you. It can be closed using @endgroup.

@group('button')
  @hassub('url')
    <a href="@sub('url')" class="button button--@sub('color')">
      @sub('label')
    </a>
  @endsub
@endgroup

To retrieve a group for a specific post, you can pass a post ID as a second parameter:

@group('button', 1)
  @hassub('url')
    <a href="@sub('url')" class="button button--@sub('color')">
      @sub('label')
    </a>
  @endsub
@endgroup

# @option

@option echo's the specified theme options field using get_field($field, 'option').

Find us on <a href="@option('facebook_url')" target="_blank">Facebook</a>

If the option is an array, you can pass the key as a second parameter:

<div class="navbar-brand">
  <a class="navbar-item" href="{{ home_url() }}">
    <img src="@option('logo', 'url')" alt="{{ get_bloginfo('name', 'display') }}" />
  </a>
</div>

# @hasoption

@hasoption is a simple conditional checking if the specified theme option field exists and is not empty. It can be closed using @endoption.

@hasoption('facebook_url')
  Find us on <a href="@option('facebook_url')" target="_blank">Facebook</a>
@endoption

If the option you are checking against is an array, you can pass the array key as a second parameter:

@hasoption('facebook', 'url')
  <a href="@option('facebook', 'url')" target="_blank">
    @hasoption('facebook', 'icon')
      <span class="icon">
        <i class="fas @option('facebook', 'icon')"></i>
      </span>
    @else 
      <span class="label">Facebook</span>
    @endoption
  </a>
@endoption

# @isoption

@isoption is a simple conditional for checking if your theme option field equals a specified value. It can be closed using @endoption.

@isoption('logo_type', 'image')
  <img src="@option('logo')" alt="{{ get_bloginfo('name', 'display') }}" />
@endoption

If the option you are checking against is an array, you can pass the array key as a second parameter and the value you are checking against as a third parameter:

@isoption('logo', 'type', 'image')
  <img src="@option('logo', 'url')" alt="{{ get_bloginfo('name', 'display') }}" />
@endoption

# @options

@options acts as a helper for handling repeater and group fields within' your theme options. Under the hood, it is essentially the exact same as @fields and @group except it automatically has the theme options ID 'option' passed to it. It can be closed using @endoptions.

@hasoption('social')
  <ul class="social">
    @options('social')
      <li>
        <a href="@sub('url')" target="_blank">
          @hassub('icon')
            <span class="icon">
              <i class="fas fa-@sub('icon')"></i>
            </span>
          @endsub
          <span>@sub('platform')</span>
        </a>
      </li>
    @endoptions
  </ul>
@endoption
