Result builder

This is the official documentation of the forestadmin/laravel-forestadmin v2+ and forestadmin/symfony-forestadmin PHP agents.

Actions can be configured to achieve different results in the GUI.

Most actions will simply perform work and display the default notification, however, other behaviors are possible:

Displaying a notification with a custom message
Displaying HTML content in a side panel
Generating a file download
Redirecting the user to another page
Calling a webhook from the user's browser (for instance to trigger a login in a third-party application)
Setting up response headers
Invalidating related data

Default behavior

The default behavior, when no exception is thrown in the handler is to display a generic notification.

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
        $builder->addAction(
            'Mark as live',
            new BaseAction(
                scope: ActionScope::SINGLE,
                execute: function(ActionContextSingle $context) {
                    // Not using the resultBuilder here will display the generic success notification.
                    // (as long as no exception is thrown)
                }
            )
        );
   }
);

Custom notifications

When customizing the notification message, you can use the ResultBuilder to generate different types of responses.

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
        $builder->addAction(
            'Mark as live',
            new BaseAction(
                scope: ActionScope::SINGLE,
                execute: function(ActionContextSingle $context, ResultBuilder $resultBuilder) {
                    if (/* ... Company is not live ... */) {
                        return $resultBuilder->success('Company is now live!');
                    } else {
                        return $resultBuilder->error('The company was already live!');
                    }
                }
            )
        );
    }
);

HTML result

You can also return an HTML page to give more feedback to the user who triggered the Action.

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
    	$builder->addAction(
    	    'Mark as live',
    	    new BaseAction(
    	    	scope: ActionScope::SINGLE,
    	    	execute: function(ActionContextSingle $context, ResultBuilder $resultBuilder) {
    	    	    /* ... charge the credit card ... */
    	    	    $record = $context->getRecord(['amount', 'source:last4']);
    	    	    if (/* ... the credit card was successfully charged ... */) {
    	    	        return $responseBuilder->success(
    	    	            'Success',
    	    	            [
    	    	                'html' => '<p class="c-clr-1-4 l-mt l-mb">'. $record['amount'] / 100 .' USD has been successfuly charged.</p>
    	    	                    <strong class="c-form__label--read c-clr-1-2">Credit card</strong>
    	    	                    <p class="c-clr-1-4 l-mb">**** **** **** '. $record['source']['last4'] .'</p>'
    	    	            ]
    	    	        );
    	    	    } else {
    	    	        return $responseBuilder->error(
    	    	            'An error occured',
    	    	            [
    	    	                'html' => '<p class="c-clr-1-4 l-mt l-mb">'. $record['amount'] / 100 .' USD has not been charged.</p>
    	    	                     <strong class="c-form__label--read c-clr-1-2">Credit card</strong>
    	    	                     <p class="c-clr-1-4 l-mb">**** **** **** '. $record['source']['last4'] .'</p>
    	    	                     <strong class="c-form__label--read c-clr-1-2">Reason</strong>
    	    	                     <p class="c-clr-1-4 l-mb">You can not charge this credit card. The card is marked as blocked</p>'
    	    	            ]
    	    	        );
    	    	    }
    	    	}
    	    )
    	);
    }
);

File generation

Because of technical limitations, Smart Actions that generate files should be flagged as such with the generateFile option.

This will cause the GUI to download the output of the action, but will also prevent from being able to use the resultBuilder to display notifications, errors, or HTML content.

Smart actions can be used to generate or download files.

The example code below will trigger a file download (with the file named filename.txt, containing StringThatWillBeInTheFile using text/plain mime-type).

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
        $builder->addAction(
            'Download a file',
            new BaseAction(
                scope: ActionScope::GLOBAL,
                isGenerateFile: true,
                execute: function(ActionContextSingle $context, ResultBuilder $resultBuilder) {
                    $myfile = fopen('filename.txt', 'w');
                    fwrite($myfile, 'StringThatWillBeInTheFile');
                    fclose($myfile);

                    return $resultBuilder->file('filename.txt', 'filename.txt', 'text/plain');
                }
            )
        );
    }
);

Redirections

To streamline your operation workflow, it could make sense to redirect to another page after an Action has successfully been executed.

It is possible using the redirectTo function.

The redirection works both for internal (\*.forestadmin.com pages) and external links.

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
        $builder->addAction(
            'Mark as live',
            new BaseAction(
                scope: ActionScope::SINGLE,
                execute: function(ActionContextSingle $context, ResultBuilder $resultBuilder) {
                    return $resultBuilder->redirectTo('/MyProject/MyEnvironment/MyTeam/data/20/index/record/20/108/activity');
                }
            )
        );
    }
);

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
        $builder->addAction(
            'Mark as live',
            new BaseAction(
                scope: ActionScope::SINGLE,
                execute: function(ActionContextSingle $context, ResultBuilder $resultBuilder) {
                    return $resultBuilder->redirectTo('https://www.royalmail.com/portal/rm/track?trackNumber=ZW924750388GB');
                }
            )
        );
    }
);

Webhooks

After an action you can set up an HTTP (or HTTPS) callback - a webhook - to forward information to other applications.

Note that the webhook will be triggered from the user's browser, so it will be subject to CORS restrictions.

Its intended use is often to perform a login on a third-party application or to trigger a background job on the current user's behalf.

use ForestAdmin\AgentPHP\DatasourceCustomizer\CollectionCustomizer;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\BaseAction;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Context\ActionContextSingle;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\ResultBuilder;
use ForestAdmin\AgentPHP\DatasourceCustomizer\Decorators\Actions\Types\ActionScope;

$forestAgent->customizeCollection(
    'Company',
    function (CollectionCustomizer $builder) {
        $builder->addAction(
            'Mark as live',
            new BaseAction(
                scope: ActionScope::SINGLE,
                execute: function(ActionContextSingle $context, ResultBuilder $resultBuilder) {
                    return $resultBuilder->webhook(
                        'http://my-company-name', // The url of the company providing the service.
                        'POST', // The method you would like to use (typically a POST).
                        [], // You can add some headers if needed.
                        ['adminToken' => 'your-admin-token'], // A body to send to the url.
                    );
                }
            )
        );
    }
);
