After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package easyadmin-tree-list-bundle

easyadmin-tree-list-bundle

EasyAdmin 3.x / Symfony 5.x compatible bundle which overrides default EasyAdmin index (list) templates and adds nested tree view on list for entities that use Gedmo Tree extension.

In order to achieve nested tree view, your entity must implement nested Gedmo tree on entity and following properties:

Example of such entity: https://github.com/doctrine-extensions/DoctrineExtensions/blob/main/doc/tree.md

Notable mentions and some history

On many Symfony 4 projects, we used 2lenet/EasyAdminPlusBundle's tree view feature. As we migrated projects to Symfony v5 / EasyAdmin v3 and Symfony v6 / EasyAdmin v4 - we lacked this simple tree view feature and decided to make tree view work again.

Hopefully bundle will work on PHP 8, Symfony 6 & EasyAdmin v4 as well (not yet tested).

History:

Installation

after installation your bundles.php will contain new bundle:

Configuration

As mentioned previously, your entity must implement Gedmo Tree.

Your EasyAdmin CRUD controller should override:

Example of src/Controller/Admin/TermCrudController.php

Easyadmin v2 to v3 migration

In EasyAdmin v2 you could access value of entity property by typing eg. entity.id. Not anymore. this was replaced by EasyAdmin's EntityDTO.

eg:

or eg: entity.root.id becomes: entity.fields.getByProperty('root').value.id

Also, befure it was easy to access custom property defined in yaml (eg. tree: true in example below):

In templates you would just use entity.tree to access it.

Now this is done by overriding configureResponseParameters of your admin crud class which extends AbstractCrudController:

And usage in Twig template:
