<p>This plugin provides an API which allows the developer of a site to add custom fields on the default menu editor.</p>
<h4>Example Initialisation</h4>
<pre><code><?php
add_action('init', 'menu_excerpt__add_menu_field');
function menu_excerpt__add_menu_field() {
    if (!is_callable('bh_add_custom_menu_fields'))
        return;

    bh_add_custom_menu_fields(array(
        'excerpt' => array(
            'description' => 'Excerpt',
            'type' => 'textarea',
            )));
}
?>
</code></pre>
<h4>Accessing the fields</h4>
<p>The easiest way to access the field(s) you’ve added is to use something along the lines of:</p>
<pre><code>$menu = 'menuName';
$posts = wp_get_nav_menu_items($menu);
foreach ($posts as $p) {
    $myitem = get_post_meta($p->ID, '_menu_item_youritem', true);
    // do with $myitem what you like - it should be a string,
    // so the simplest thing is to "echo" it
}
</code></pre>
<p>you can use menu locations to get the menu name if you prefer – replace the first line above with:</p>
<pre><code>$locations = get_nav_menu_locations();
$menu = $locations['locationName'];
</code></pre>
<p>menu locations are useful if you like to swap your menus about.</p>
<p>Unfortunately these examples don’t allow the use of wordpress’ inbuilt menu walkers. To use those you will need to create a custom walker_nav_menu class and access the custom fields with something along the lines of (very stripped down example will need fleshing out for full walker functionality – there are tutorials on the net for custom nav walkers):</p>
<pre><code>class mywalker extends Walker_Nav_Menu {
    function start_el(&$output, $item, $depth, $args) {
        echo $item->custom_field
    }
}
</code></pre>
<p>The important bit here is that the field is placed on the second variable which behaves like an object. the custom_field part is the name you gave your field with dashes replaced with underscores (to allow the name to be used in an accessor).</p>
<h4>NOTE</h4>
<p>This plugin does nothing by itself. It provides an API only.</p>


Custom Menu Fields

Provides an API to add custom fields to the menu editor.

<p>A field for Advanced Custom Fields that forces the user to crop their image to specific aspect ratio or pixel size after uploading. Using an aspect ratio is especially useful in responsive image use cases.</p>
<p>After cropping, a new cropped image variant is created in the gallery and saved into the post. Thumbnails are also generated for the new image. User can re-crop the original image at any time from the post page.</p>
<p>The cropped image variants are hidden by default in the media browser and on the media page but you can view them by selecting the “list view” on the media page.</p>
<p>There are three modes of operation: aspect ratio, pixel size and free crop. You can select this option when creating the field in ACF field options.</p>
<h4>Aspect ratio</h4>
<p>Use this option if you want the image to be of specific aspect ratio like 16:9 but the pixel size is not important.</p>
<p>After selecting an image, user can select an area from the image that matches this aspect ratio. When crop button is pressed, the area is cropped from the original image.</p>
<p>If you need a smaller image size, you make use of WordPress’s thumbnail functionality to access a smaller version of the image.</p>
<h4>Pixel size</h4>
<p>Use this option if you need a specific pixel size image like 640×480. User will not be able to select an image smaller than the defined pixel size.</p>
<p>After selecting an image, user can select an area from the image they want, which can be larger than the pixel size but may not be smaller. The aspect ratio of the selection is locked according to the pixel size.</p>
<p>When crop button is pressed, the area is cropped from the original image. After the crop is complete, the image will be automatically scaled down to the pixel size. This means the final image will always be the specified size.</p>
<h4>Free crop</h4>
<p>Crop can be done freely, there are no aspect ratio limitations.</p>
<h4>Requirements</h4>
<ul>
<li>WordPress 4.9 or later</li>
<li>PHP 5.6 or later</li>
<li>Advanced Custom Fields 5.8 or later (Pro or Free)</li>
</ul>
<h4>Compatibility</h4>
<ul>
<li>Polylang Pro</li>
<li>Enable Media Replace</li>
<li>
<p>WP Offload Media, Media Cloud and other plugins that move media files to remote location</p>
</li>
