Ideas on how to Implant a set of Forms

Symfony Models is also implant a set of a number of other variations, that is good for revise related entities in one single mode. In this article, possible perform an application to help you change a task classification and you will, best from inside the exact same function, you’ll modify, manage and take away of many Tag things about one Task.

Just how to Embed some Versions

Next, why don’t we carry out a type for the task organization, using good CollectionType realm of TagType versions. This may allow us to customize the Mark areas of a role best in activity form in itself:

In the event that member submits the form, this new filed investigation to your tags career is employed to build an enthusiastic ArrayCollection out of Level things. Brand new collection will then be intent on the new level realm of the brand new Activity and will end up being utilized via $task->getTags() .
