Fields

Edit this page

Fields allow to display the contents of your Doctrine entities on each CRUD page. EasyAdmin provides built-in fields to display all the common data types, but you can also create your own fields.

Configuring the Fields to Display

If your CRUD controller extends from the AbstractCrudController provided by EasyAdmin, the fields are configured automatically. In the index page you'll see a few fields and in the rest of pages you'll see as many fields as needed to display all the properties of your Doctrine entity.

Implement the configureFields() method in your CRUD controller to customize the list of fields to display:

1
2
3
4
5
6
7
8
9
10
11
12
13

namespace App\Controller\Admin;

use App\Entity\Product;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;

class ProductCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Product::class;
    }

    public function configureFields(string $pageName): iterable
    {
        // ...
    }

    // ...
}

There are several ways of defining the list of fields to display.

Option 1. Return strings with the name of the properties to display. EasyAdmin creates fields automatically for them and applies the default config options:

1
2
3
4
5
6
7
8
9
10
public function configureFields(string $pageName): iterable
{
    return [
        'title',
        'description',
        'price',
        'stock',
        'publishedAt',
    ];
}

Option 2. Return Field objects created for the Doctrine entity properties. EasyAdmin transforms these generic Field objects into the specific objects used to display each type of property:

1
2
3
4
5
6
7
8
9
10
11
12
use EasyCorp\Bundle\EasyAdminBundle\Field\Field;

public function configureFields(string $pageName): iterable
{
    return [
        Field::new('title'),
        Field::new('description'),
        Field::new('price'),
        Field::new('stock'),
        Field::new('publishedAt'),
    ];
}

Option 3. Return the appropriate field objects to display each property:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
use EasyCorp\Bundle\EasyAdminBundle\Field\DateTimeField;
use EasyCorp\Bundle\EasyAdminBundle\Field\IntegerField;
use EasyCorp\Bundle\EasyAdminBundle\Field\MoneyField;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextEditorField;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextField;

public function configureFields(string $pageName): iterable
{
    return [
        TextField::new('title'),
        TextEditorField::new('description'),
        MoneyField::new('price')->setCurrency('EUR'),
        IntegerField::new('stock'),
        DateTimeField::new('publishedAt'),
    ];
}

The only mandatory argument of the field constructors is the name of the Doctrine entity property managed by this field. EasyAdmin uses the PropertyAccess component to get the value of the properties, so the entity can define their access as public properties (e.g. public $firstName) or public methods (e.g. public function getFirstName(), public function firstName()).

Note

EasyAdmin uses Symfony Forms to create and edit Doctrine entities. That's why all entity properties must be nullable: their setters need to accept null values and their getters must be allowed to return null. In the database, the associated fields don't have to be nullable.

Unmapped Fields

Fields usually reference to properties of the related Doctrine entity. However, they can also refer to methods of the entity which are not associated to any properties. For example, if your Customer entity defines the firstName and lastName properties, you may want to display a "Full Name" field with both values merged.

To do so, add the following method to the entity:

1
2
3
4
5
6
7
8
9
10
11
12
use Doctrine\ORM\Mapping as ORM;

/** @ORM\Entity */
class Customer
{
    // ...

    public function getFullName()
    {
        return $this->getFirstName().' '.$this->getLastName();
    }
}

Now, add a fullName field that refers to this getFullName() method. The conversion between field names and methods must comply with the rules of the PropertyAccess component (e.g. foo_bar -> getFooBar() or fooBar()):

1
2
3
4
5
6
7
public function configureFields(string $pageName): iterable
{
    return [
        TextField::new('fullName'),
        // ...
    ];
}

The main limitation of unmapped fields is that they are not sortable because they cannot be included in the Doctrine query.

Displaying Different Fields per Page

There are several methods to display fields conditionally depending on the current page:

1
2
3
4
5
6
7
8
9
10
11
public function configureFields(string $pageName): iterable
{
    return [
        IdField::new('id')->hideOnForm(),
        TextField::new('firstName'),
        TextField::new('lastName'),
        TextField::new('phone'),
        EmailField::new('email')->hideOnIndex(),
        DateTimeField::new('createdAt')->onlyOnDetail(),
    ];
}

These are all the available methods:

  • hideOnIndex()
  • hideOnDetail()
  • hideOnForm() (hides the field both in edit and new pages)
  • hideWhenCreating()
  • hideWhenUpdating()
  • onlyOnIndex()
  • onlyOnDetail()
  • onlyOnForms() (hides the field in all pages except edit and new)
  • onlyWhenCreating()
  • onlyWhenUpdating()

If the fields to display are completely different on each page, use the given $pageName argument to differentiate them:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
use EasyCorp\Bundle\EasyAdminBundle\Config\Crud;

public function configureFields(string $pageName): iterable
{
    $id = IdField::new('id');
    $firstName = TextField::new('firstName');
    $lastName = TextField::new('lastName');
    $phone = TextField::new('phone');
    $email = EmailField::new('email');
    $createdAt = DateTimeField::new('createdAt');

    if (Crud::PAGE_INDEX === $pageName) {
        return [$id, $firstName, $lastName, $phone];
    } elseif(Crud::PAGE_DETAIL === $pageName) {
        return ['...'];
    } else {
        return ['...'];
    }
}

If you need even greater control, consider using the following way of defining the fields using PHP generators:

1
2
3
4
5
6
7
8
9
10
11
12
13
public function configureFields(string $pageName): iterable
{
    yield IdField::new('id')->hideOnForm();

    if ('... some expression ...') {
        yield TextField::new('firstName');
        yield TextField::new('lastName');
    }

    yield TextField::new('phone');
    yield EmailField::new('email')->hideOnIndex();
    yield DateTimeField::new('createdAt')->onlyOnDetail();
}

Field Layout

Form Rows

By default, EasyAdmin displays one form field per row. Inside the row, each field type uses a different default width (e.g. integer fields are narrow and code editor fields are very wide). You can override this behavior with the setColumns() method of each field.

Before using this option, you must be familiar with the Bootstrap grid system, which divides each row into 12 same-width columns, and the Bootstrap breakpoints, which are xs (device width < 576px), sm (>= 576px), md (>= 768px), lg (>= 992px), xl (>= 1,200px) and xxl (>= 1,400px).

Imagine that you want to display two fields called startsAt and endsAt on the same row, each of them spanning 6 columns of the row. This is how you configure that layout:

1
2
3
4
5
6
7
8
9
10
11
use EasyCorp\Bundle\EasyAdminBundle\Field\DateTimeField;

public function configureFields(string $pageName): iterable
{
    return [
        // ...,

        DateTimeField::new('startsAt')->setColumns(6),
        DateTimeField::new('endsAt')->setColumns(6),
    ];
}

This example renders both fields on the same row, except in xs and sm breakpoints, where each field takes the entire row (because the device width is too small).

If you need a better control of the design depending on the device width, you can pass a string with the responsive CSS classes that define the width of the field on different breakpoints:

1
2
3
4
5
6
7
8
9
10
11
use EasyCorp\Bundle\EasyAdminBundle\Field\DateTimeField;

public function configureFields(string $pageName): iterable
{
    return [
        // ...,

        DateTimeField::new('startsAt')->setColumns('col-sm-6 col-lg-5 col-xxl-3'),
        DateTimeField::new('endsAt')->setColumns('col-sm-6 col-lg-5 col-xxl-3'),
    ];
}

This example adds col-sm-6 to override the default EasyAdmin behavior and display the two fields on the same row also in the sm breakpoint. Besides, it reduces the number of columns in larger breakpoints (lg and xxl) to improve the rendering of those fields.

Tip

You can also use the CSS classes related to reordering and offseting columns:

1
yield DateTimeField::new('endsAt')->setColumns('col-sm-6 col-xxl-3 offset-lg-1 order-3');

Because of how Bootstrap grid works, when you configure field columns manually, each row will contain as many fields as possible. If one field takes 4 columns and the next one takes 3 columns, the row still has 12 - 4 - 3 = 5 columns to render other fields. If the next field takes more than 5 columns, it renders on the next row.

Sometimes you need a better control of this automatic layout. For example, you might want to display two or more fields on the same row, and ensure that no other field is displayed on that row, even if there's enough space for it. To do so, use the addRow() method of the special FormField field to force the creation of a new line (the next field will forcibly render on a new row):

1

use EasyCorp\Bundle\EasyAdminBundle\Field\BooleanField;
use EasyCorp\Bundle\EasyAdminBundle\Field\DateTimeField;
use EasyCorp\Bundle\EasyAdminBundle\Field\FormField;

public function configureFields(string $pageName): iterable
{
    return [
        // ...,

        DateTimeField::new('startsAt')->setColumns('col-sm-6 col-lg-5 col-xxl-3'),
        DateTimeField::new('endsAt')->setColumns('col-sm-6 col-lg-5 col-xxl-3'),
        FormField::addRow(),

        // you can pass the name of the breakpoint to add a row only on certain widths
        // FormField::addRow('xl'),

        // this field will always render on its own row, even if there's
        // enough space for it in the previous row in `lg`, `xl` and `xxl` breakpoints
        BooleanField::new('published')->setColumns(2),
    ];
}

Form Panels

In pages where you display lots of fields, you can divide them in groups using the "panels" created with the special FormField object:

1
2
3
4
5
6
7
8
9

30
use EasyCorp\Bundle\EasyAdminBundle\Field\FormField;

public function configureFields(string $pageName): iterable
{
    return [
        IdField::new('id')->hideOnForm(),

        // panels usually display only a title
        FormField::addPanel('User Details'),
        TextField::new('firstName'),
        TextField::new('lastName'),

        // panels without titles only display a separation between fields
        FormField::addPanel(),
        DateTimeField::new('createdAt')->onlyOnDetail(),

        // panels can also define their icon, CSS class and help message
        FormField::addPanel('Contact information')
            ->setIcon('phone')->addCssClass('optional')
            ->setHelp('Phone number is preferred'),
        TextField::new('phone'),
        TextField::new('email')->hideOnIndex(),

        // panels can be collapsible too (useful if your forms are long)
        // this makes the panel collapsible but renders it expanded by default
        FormField::addPanel('Contact information')->collapsible(),
        // this makes the panel collapsible and renders it collapsed by default
        FormField::addPanel('Contact information')->renderCollapsed(),
    ];
}

Form Tabs

In pages where you display lots of fields, you can divide them in tabs using the "tabs" created with the special FormField object:

1
2
3
4
5
6
7
8
9
10
11
12

use EasyCorp\Bundle\EasyAdminBundle\Field\FormField;

public function configureFields(string $pageName): iterable
{
    return [
        IdField::new('id')->hideOnForm(),

        // Add a tab
        FormField::addTab('First Tab'),

        // You can use a Form Panel inside a Form Tab
        FormField::addPanel('User Details'),

        // Your fields
        TextField::new('firstName'),
        TextField::new('lastName'),

        // Add a second Form Tab
        // Tabs can also define their icon, CSS class and help message
        FormField::addTab('Contact information Tab')
            ->setIcon('phone')->addCssClass('optional')
            ->setHelp('Phone number is preferred'),

        TextField::new('phone'),

    ];
}

Label Options

The second optional argument of the field constructors is the label:

1
2
3
4
5
6
7
8
9
10
// not defining the label explicitly or setting it to NULL means
// that the label is autogenerated (e.g. 'firstName' -> 'First Name')
TextField::new('firstName'),
TextField::new('firstName', null),

// set the label explicitly to display exactly that label
TextField::new('firstName', 'Name'),

// set the label to FALSE to not display any label for this field
TextField::new('firstName', false),

TextField::new('firstName', 'Name')
    // CSS class/classes are applied to the field contents (in the 'index' page)
    // or to the row that wraps the contents (in the 'detail', 'edit' and 'new' pages)

    // use this method to add new classes to the ones applied by EasyAdmin
    ->addCssClass('text-large text-bold')
    // use this other method if you want to remove any CSS class added by EasyAdmin
    ->setCssClass('text-large text-bold')

    // this defines the Twig template used to render this field in 'index' and 'detail' pages
    // (this is not used in the 'edit'/'new' pages because they use Symfony Forms themes)
    ->setTemplatePath('admin/fields/my_template.html.twig')

    // useful for example to right-align numbers/money values (this setting is ignored in 'detail' page)
    ->setTextAlign('right')

Formatting Options

The formatValue() method allows to apply a PHP callable to the value before rendering it in the index and detail pages:

    // callbacks usually take only the current value as argument
    ->formatValue(function ($value) {
        return $value < 10 ? sprintf('%d **LOW STOCK**', $value) : $value;
    });

TextEditorField::new('description')
    // callables also receives the entire entity instance as the second argument
    ->formatValue(function ($value, $entity) {
        return $entity->isPublished() ? $value : 'Coming soon...';
    });

// in PHP 7.4 and newer you can use arrow functions
// ->formatValue(fn ($value) => $value < 10 ? sprintf('%d **LOW STOCK**', $value) : $value);
// ->formatValue(fn ($value, $entity) => $entity->isPublished() ? $value : 'Coming soon...');

    // help message displayed for this field in the 'detail', 'edit' and 'new' pages
    ->setHelp('...')

    // the Symfony Form type used to render this field in 'edit'/'new' pages
    // (fields have good default values for this option, so you don't usually configure this)
    ->setFormType(TextType::class)

    // an array of parameters passed to the Symfony form type
    // (this only overrides the values of the passed form type options;
    // it leaves all the other existing type options unchanged)
    ->setFormTypeOptions(['option_name' => 'option_value'])

Fields Reference

Note

This section is not ready yet. We're working on it. Meanwhile, you can rely on your IDE auto-completion to discover all the config options of each field.

Creating Custom Fields

A field is a class that implements EasyCorp\Bundle\EasyAdminBundle\Contracts\Field\FieldInterface. Although the interface only requires to implement a few methods, you may want to add all the methods available in built-in fields to configure all the common field options. You can use the EasyCorp\Bundle\EasyAdminBundle\Field\FieldTrait for that.

Imagine that you want to create a custom MapField that renders a full map for a given postal address. This is the class you could create for the field:

namespace App\Admin\Field;

use EasyCorp\Bundle\EasyAdminBundle\Contracts\Field\FieldInterface;
use EasyCorp\Bundle\EasyAdminBundle\Field\FieldTrait;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;

final class MapField implements FieldInterface
{
    use FieldTrait;

    /**
     * @param string|false|null $label
     */
    public static function new(string $propertyName, $label = null): self
    {
        return (new self())
            ->setProperty($propertyName)
            ->setLabel($label)

            // this template is used in 'index' and 'detail' pages
            ->setTemplatePath('admin/field/map.html.twig')

            // this is used in 'edit' and 'new' pages to edit the field contents
            // you can use your own form types too
            ->setFormType(TextareaType::class)
            ->addCssClass('field-map')

            // loads the CSS and JS assets associated to the given Webpack Encore entry
            // in any CRUD page (index/detail/edit/new). It's equivalent to calling
            // encore_entry_link_tags('...') and encore_entry_script_tags('...')
            ->addWebpackEncoreEntries('admin-field-map')

            // these methods allow to define the web assets loaded when the
            // field is displayed in any CRUD page (index/detail/edit/new)
            ->addCssFiles('js/admin/field-map.css')
            ->addJsFiles('js/admin/field-map.js')
        ;
    }
}

Next, create the template used to render the field in the index and detail CRUD pages. The template can use any Twig templating features and the following variables:

  • ea, a EasyCorp\Bundle\EasyAdminBundle\Context\AdminContext instance which stores the admin context and it's available in all backend templates;
  • field, a EasyCorp\Bundle\EasyAdminBundle\Dto\FieldDto instance which stores the config and value of the field being rendered;
  • entity, a EasyCorp\Bundle\EasyAdminBundle\Dto\EntityDto instance which stores the instance of the entity which the field belongs to and other useful data about that Doctrine entity.

Note

This template is not used in the edit and new CRUD pages, which use Symfony Form themes to define how each form field is displayed.

That's all. You can now use this field in any of your CRUD controllers:

1
2
3
4
5
6
7
8
9
use App\Admin\MapField;

public function configureFields(string $pageName): iterable
{
    return [
        // ...
        MapField::new('shipAddress'),
    ];
}

Custom Options

If your field is configurable in any way, you can add custom options for it. The recommended way of adding options is defining their names as public constants in the field object and use the setCustomOption() method defined in the FieldTrait to set their values.

Imagine that the MapField defined in the previous section allows to use either Google Maps or OpenStreetMap to render the maps. You can add that option as follows:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

22
23
24
25
26
27
28
29
30
31
32
33
namespace App\Admin\Field;

use EasyCorp\Bundle\EasyAdminBundle\Contracts\Field\FieldInterface;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;

final class MapField implements FieldInterface
{
    use FieldTrait;

    public const OPTION_MAP_PROVIDER = 'mapProvider';

    public static function new(string $propertyName, ?string $label = null): self
    {
        return (new self())
            // ...
            ->setCustomOption(self::OPTION_MAP_PROVIDER, 'openstreetmap')
        ;
    }

    public function useGoogleMaps(): self
    {
        $this->setCustomOption(self::OPTION_MAP_PROVIDER, 'google');

        return $this;
    }

    public function useOpenStreetMap(): self
    {
        $this->setCustomOption(self::OPTION_MAP_PROVIDER, 'openstreetmap');

        return $this;
    }
}

Later you can access these options via the getCustomOptions() method of the field DTO. For example, in a Twig template:

1
2
3
4
5
6
7
8
9
10
11
{# admin/field/map.html.twig #}
{% if 'google' === field.customOptions.get('mapProvider') %}
    {# ... #}
{% endif %}

{# if you defined the field options as public constants, you can access
   them in the template too (although resulting code is a bit verbose) #}
{% set map_provider_option = constant('App\\Admin\\MapField::OPTION_MAP_PROVIDER') %}
{% if 'google' === field.customOptions.get(map_provider_option) %}
    {# ... #}
{% endif %}

Field Configurators

Some default options of some fields depend on the value of the of the entity property, which is only available during runtime. That's why you can optionally define a field configurator, which is a class that updates the config of the field before rendering them.

EasyAdmin defines lots of configurators for its built-in fields. You can create your own configurators too (either to configure your own fields and/or the built-in fields). Field configurators are classes that implement EasyCorp\Bundle\EasyAdminBundle\Contracts\Field\FieldConfiguratorInterface.

Once implemented, define a Symfony service for your configurator and tag it with the ea.field_configurator tag. Optionally you can define the priority attribute of the tag to run your configurator before or after the built-in ones.
