Location

Location

Field groups won't do any good if they don't belong to any locations. If you don't set a location, the field group won't appear anywhere.

To change this default configuration, use the FieldsBuilders->setLocation($param, $operation, $value) method.

use StoutLogic\AcfBuilder\FieldsBuilder;

$banner = new FieldsBuilder('banner')
$banner
    ->addText('title')
    ->addWysiwyg('content')
    ->setLocation('post_type', '==', 'page')

This will make the banner field group appear on all pages.

Complex Logic

We can do some more complex logic, if we have multiple conditions of where a field group should appear. To add more rules, use the and and or methods. or is higher in the order of operations than and is, so the logic should be structured as:

(condition 1 and condition 2) or (condition 3 and condition 4)

In order to express:

(condition 2) and (condition 1 or condition 3)

The common condition must be distributed and be expressed as:

(condition 1 and condition 2) or (condition 3 and condition 2)

This is due to the way ACF stores conditions in a 3 dimensional array.

use StoutLogic\AcfBuilder\FieldsBuilder;

$banner = new FieldsBuilder('banner')

$banner
    ->addText('title')
    ->addWysiwyg('content')
    ->setLocation('post_type', '==', 'page')
        ->or('post_type', '==', 'post')
        ->and('post', '!=', '10')
    ->addText('subtitle');

This logic says that the banner should appear on a page or a post, and that post can't have a post id of 10. Also notice that setLocation doesn't have to be added last. $banner->build will generate:

...,
'fields' => [
    [
        'name' => 'title',
        ...
    ],
    [
        'name' => 'content',
        ...
    ],
    [
        'name' => 'subtitle',
        ...
    ],
],
'location' => [
    [
        [
            'param' => 'post_type',
            'operator'  =>  '==',
            'value' => 'page',
        ],
    ],
    [
        [
            'param' => 'post_type',
            'operator'  =>  '==',
            'value' => 'post',
        ],
        [
            'param' => 'post',
            'operator'  =>  '!=',
            'value' => '10',
        ],
    ],
]
...

Modify Locations

If you have a builder already constructed with a location set and you need to add another or condition, use the getLocation method

$banner
    ->getLocation()
    ->or('post_type', '==', 'team_member');

This will add the banner to all team_member post types as well.
