Dynamic Input

The dynamic input is a simple yet powerful formfield allowing you to provide selects, number or text inputs, checkboxes, radios and switches based on your conditions/code.

To retreive the possible options, Voyager will fetch a route you define in the formfield options.
This route has to return a JSON object containing the set of fields you want to show.

For easy use Voyager provides a class VoyagerAdmin\Voyager\Classes\DynamicInput that helps you create those responses.

Knowing the BREAD action

The incoming request contains a parameter bread_action which can be query, browse, edit or add.

Using no keys on inputs

Sometimes its useful to use no key on an input.
That way a single select with multiple=false will only store the selected value in the database instead of a key-value pair.
But be aware that only one input total without a key can exist in a formfield.
Otherwise an Exception Only one input without a key can exist! will be thrown.

Examples

Single select without a key

This example shows a single select with two options English and German.

<?php

use VoyagerAdmin\Voyager\Classes\DynamicInput;

class MyController {
    public function getOptions() {
        return (new DynamicInput())->addSelect(null, 'Select a language', ['en' => 'English', 'de' => 'German']);
    }
}

The data stored in the database will be en or de.

Single select with a key

This example shows a single select with two options English and German.

<?php

use VoyagerAdmin\Voyager\Classes\DynamicInput;

class MyController {
    public function getOptions() {
        return (new DynamicInput())->addSelect('language', 'Select a language', ['en' => 'English', 'de' => 'German']);
    }
}

The data stored in the database will be ['language' => 'en'] or ['language' => 'de'].

Selects based on previous selection

In this example the user is asked to select a country first.
Once the country is selected, another select is shown which allows the user to enter the state.

<?php

use VoyagerAdmin\Voyager\Classes\DynamicInput;

class MyController {
    public function getOptions() {
        $country = $request->input('country');
        $input = (new DynamicInput())->addSelect('country', 'Select your country', ['us' => 'United States', 'de' => 'Germany']);

        if ($country == 'us') {
            $input->addSelect('state', 'Select your state', ['ny' => 'New York', 'wt' => 'Washington', /* ... */]);
        } elseif ($country == 'de') {
            $input->addSelect('state', 'Select your state', ['by' => 'Bavaria', 'ber' => 'Berlin', /* ... */]);
        }

        return $input;
    }
}

When selecting country United States and state New York, the data stored in the database will look like this:

{
    "country": "us",
    "state": "New York"
}
