README
Conditionally load a field with the value of the other fields.
Installation
Via composer: composer require armincms/chain
.
Usage
The Chain field works as a trigger
and listener
. a trigger
chain listens to the update events of entire fields and the listener
chain listening to the trigger
Chain events and its entire fields together.
Make trigger field
The trigger
Chain initializes via the as
method. the as
method accepts two arguments. the first argument is the name of event
and the second argument is a fields
callback. it receives a request instance for resolving fields.
Chain::as('name', function() {
return [
Text::make('Name')
->sortable()
->rules('required', 'max:255'),
Text::make('Username')
->sortable()
->rules('required', 'max:255'),
];
}),
Make listener field
The listener
Chain initializes via the with
method. the with
method accepts an array of events
as the first argument and a callback for the fields as second arguemnt.
for listening to a trigger
Chain you should pass the name
of the Chain as the event
name. for listening to a field of a trigger
Chain you can prefix the field name by the Chain name
and listen to it. for example, you can listen to the name
field of a Chain (Chain field named by the 'test'), with the test.name
event.
Chain::with('name', function($request) {
if($request->filled('username')){
return [
Text::make('Password')
->sortable()
->rules('required', 'max:255'),
Text::make('Confirmation')
->sortable()
->rules('required', 'max:255'),
];
}
return [];
}, 'second-chain'),
Chain::with('second-chain.confirmation', function($request) {
return [
Boolean::make('Passed')
->readonly()
->withMeta(['value' => 1]),
];
}),
