PHP System Dendrogram

##dendrogramLaravelPHP##v1.0

5.*	>=5.6.4

Installation

composer require dendrogram/dendrogram:v1.0

Configuration

First register the ServiceProvider in the Laravel application, open the file config/app.php, add an item in providers:

'providers' => [
    DenDroGram\DendrogramServiceProvider::class ]

Then publish the configuration file of the expansion package, use the following command ：

php artisan vendor:publish

At this time, the dendrogram.php configuration file will be generated in the config directory

Data import (Two tables and three custom functions)

php artisan migrate

adjacency structure Chain query based on the parent node is easy to add and delete and inconvenient to query

nested structure uses left and right value inclusive form to make additions and deletions inconvenient and easy to query

Construction parameters	Method description	Method Parameters	Return	Remarks
					##(new DenDroGram(AdjacencyList::class))->getTreeData ($node_id);
adjacency data is constructed into a multi-dimensional array	Root node id	Return array	Multi-dimensional Array structure		(new DenDroGram(NestedSet::class))->buildTree($node_id,['name'])
NestedSet format data generates a rhizomatic structure tree	Root node id, each node displays information	Returns html text string	View related in dendrogram.php Configure routes such as operating node methods		(new DenDroGram(NestedSet::class))->operateNode($action,$data)
Node operations for data in NestedSet format	action adds, deletes, and changes identifiers, data node details data	returns boolean	Note that the view corresponds to the data structure NestedSet: :class
