Prerequisites

PHP v 5.2.0+
Prototype v 1.6+ is required
Of course sfDoctrinePlugin

Features

• Display a doctrine nested set and insert, rename and delete nodes through a context menu and ajax:

  

• Move complete branches of the tree through drag-drop and save the history of changes in a single ajax call:

  

• Customize the node links through a template to integrate the tree in multiple situations.
  Simple link here, but could be a remote link too:

  <?php echo link_to($record->get($field), "$model/edit?id=$identifier"); ?>
  

Browser compatibility

Tested on IE 6, 7 and 8, Firefox 2 and 3 Opera 9 on Windows.
Let me know if you find compatibility problems on other platforms.

Installation

Install plugin as usual.
For Symfony 1.2 and 1.3, enable plugins sfDoctineTreePlugin and sfProtoculousPlugin.
For Symfony 1.0, update the Prototype js files to version 1.6 minimum.
Create a nested set model according to Doctrine documentation.
You must enable the module sfDoctrineTree in your application settings.yml:

all:
  .settings:
     enabled_modules:        [default, sfDoctrineTree]

Create a link or virtual directory called sfDoctrineTreePlugin, pointing to the web folder of the plugin.

Settings and customization

Callbacks

You can override the way sfDoctrineTreePlugin renames and deletes records by including callback methods in the table class of the model.
These methods are: customizeTreeUpdateQuery and customizeTreeSelectForDeleteQuery, they take a query object as a parameter and return a query object, so you can either add to the query or replace it in the method. For example, for a model called Category, you would add the following method to add a where clause. (For security or other) This method will be called to get the update query:

public function customizeTreeUpdateQuery($q)
{
  $securityField = Utils::getSecurityField();
  return $q->addWhere('security_field = ?', $securityField);
}

Similarly the callback method customizeChildToAdd gives you a chance to update properties of a record before it is inserted as a child:

public function customizeChildToAdd($child)
{
  $child->security_field = Utils::getSecurityField();
  return $child;
}

Setting in app.yml

You can change the following setting by defining them in app.yml:

app_doctrine_tree_rename_url default: sfDoctrineTree/rename
app_doctrine_tree_delete_url default: sfDoctrineTree/delete
app_doctrine_tree_add_child_url default: sfDoctrineTree/add_child
app_doctrine_tree_save_tree_url default: sfDoctrineTree/save_tree

These setting will be applied to all trees in the application

Options in the helper function

The helper include_doctrine_tree takes several options that modify the behavior of the tree.
This gives you the ability to set different options for each tree.

• link_partial: Allows you to change the default link template for the nodes. (default is: 'yourmodel/edit')
• max_depth: Limits the depth where people can add or drop nodes
• no_help: Hides the help link and div
• no_root_rename: Hides the Rename context menu for the root

All other options will be passed as HTML attributes of the nodes. (not the root)
Some of them will be interpreted by the js tree object:

• noAdd: Hides the Add node context menu
• noRename: Hides the Rename context menu
• noDelete: Hides the Delete context menu
• noDrag: Keeps the nodes from being moved
• noSiblings: Keeps the nodes from being dropped between 2 nodes

Limitations

sfDoctrineTreePlugin will not work with tables having composite keys.
It is the responsibility of your application to create the root(s) of the tree.
Context menus do not work with Right Click on Opera, Ctrl + Left Click is used instead.

Usage

<?php
use_helper('DoctrineTree');

// Category nested set with 1 root
// include_doctrine_tree('Category', 'name');

// Comments nested set with multiple roots
// include_doctrine_tree('Comment', 'title', 1); // 3rd argument is the root id of the nested set tree

// Comments nested set with one root, using options and custom base query
// include_doctrine_tree('Comment', 'title', 0, array('link_partial' => 'my_module/my_partial', 'max_depth' => 8, 'no_root_rename' => 'true', 'noRename' => 'true', 'noDelete' => 'true', 'noSiblings' => 'true'), CommentTable::getTreeBaseQuery);
