Generic Object

This user manuel applies to version 2.0 of the GLPI Generic Object Plugin.


This plugin requires :

  • PHP 5.3 or higher
  • GLPI >= 0.83.x


This plugin allows you to add new inventory objects types, integrated into GLPI framework.

It supports following GLPI features:

  • entity and sub-entities management;
  • search;
  • templates;
  • history;
  • helpdesk integration;
  • CSV file injection plugin integration;
  • Item uninstallation plugin integration;
  • order management plugin integration.

Example of usage

Objective: Manage your car fleet like the rest of your IT Assets.

  • Create a new type of inventory object car.
  • Add the accurate fields for a car, like: name, serial number, inventory number, type, model, color, state, etc.
  • Describe the behaviour of a car: visible in subentity, retain history, etc.
  • Adjust the rights on cars.
  • Activate the cars object.
  • Manage your collection of cars in GLPI.

Install the plugin

  • Uncompress the archive.
  • Move the genericobject directory to the <GLPI_ROOT>/plugins directory
  • Navigate to the Configuration > Plugins page,
  • Install and activate the plugin.

Update the plugin

In order to get the plugin fully working; you will have to take some precautions trying to upgrade.

First of all, do a backup of your database and your files!

Make sure the old generated files are present in their original emplacement (should be in glpi/files/_plugins/genericobject directory). If you have moved your instance, you may have to copy them from the old one. Also remember to copy glpi_plugin_genericobject_* tables from the original database to the new one, if any.


In older versions of the plugin; generated files were stored in the plugin directory itself (into the inc, front and locales directories). In that case, you must copy them to their original location.

Once this is done, you should be ready to process. Go to the plugin administration page, and click Upgrade, then Enable.

On some instances, even if the class files are generated during upgrade, you may have to manualy generate them again.

Finally; disable and enable again the plugin; and logout from GLPI to be sure all menus and links are up to date.


Create a new object type

This is the first step.

  • Click on the + button in the plugin configuration form.
  • Create the new type of inventory object:
    • name: mandatory, lowercase, and must be composed of letters only;
    • label: by default, the same as the name.
  • Validate.
  • Activate the new item type to use it.

Example: Create a new type of inventory object car.

Edit labels

For each type, a language file is available in <GLPI_ROOT>/files/_plugins/genericobject/locales/itemtype/

The plugin creates :

  • a language file for the current language
  • a language file for the default GLPI language


If the current and default languages are the same, only one file is created.

To change the label of the itemtype, for the english language, edit the file:

// <GLPI_ROOT>/files/_plugins/genericobject/locales/<itemtype>/<itemtype>.en_GB.php
$LANG['genericobject']['<itemtype>'][1] = "<type's label>";

Setup behaviour

Example: Describe the behaviour of a car: visible in subentity, retain history, etc.

The new type will be managed the same way as the usual GLPI types (computer, monitor, network device, etc.)


All objects are at least assigned to an entity

The Behaviour tab allows you to define:

  • child-entities: allows the type to be recursive;
  • Helpdesk: allows an object to be associated to a ticket;
  • Trash: use GLPI’s trash functionnality;
  • Notes: use GLPI’s note functionnality;
  • History: allow history for this type;
  • Templates: allows template management;
  • Documents: allows documents to be attached to an object of this type;
  • Loans: allows objects to be loaned;
  • Contracts: link an object to one or more contracts;
  • Network connections: allow ports to be used and management for this type;
  • CSV file injection plugin: allows this type to be available for use in the plugin;
  • Item uninstallation plugin: allows this type to be uninstalled;
  • Order management plugin: allows this type to be linked to an order;

Add Fields

Example: Add the accurate fields for a car, like: name, serial number, inventory number, type, model, color, state, etc.

Navigate to the Fields tab.

The plugin comes with several ready to use fields:

  • Name
  • Type
  • Model
  • Serial number
  • Inventory number
  • Item’s user
  • Group
  • Status
  • Comments
  • Notes
  • Location
  • Other
  • Manufacturer
  • URL
  • Creation date
  • Expiration date
  • Category
  • Visible in Helpdesk
  • Technician in charge of the hardware
  • Domain
  • Contact
  • Contact number


Using some behaviour will automatically add some fields to the object:

  • network connection => location
  • loans => location
  • helpdesk => is visible in Helpdesk
  • notes => notepad

Helpdesk integration

To use an object in the helpdesk, use following setup:

  • In Behaviour tab : use helpdesk must be set to Yes.
  • if the User field is defined, it allows item to be visible in the My Items list (as item whose owner is the user).
  • if the Group field is defined, it allows item to be visible in the My Items list too (as item belonging to a group in which the user belongs to).
  • if Helpdesk visible field is set and if the value is set to No in the object, then the object won’t be visible at all in the helpdesk.

Add new fields


New fields will be available for all object’s types.

  • Create a new file named <GLPI_ROOT>/files/_plugins/genericobject/fields/<type>.constant.php

For example, for a car type the constant file will be <GLPI_ROOT>/files/_plugins/genericobject/fields/car.constant.php.

Please note that the file’s first line must be the following, otherwise the new fields won’t appear in the list:

global $GO_FIELDS, $LANG;
  • Add the new fields definitions.

Add a simple dropdown field

$GO_FIELDS['plugin_genericobject_mytypecolors_id']['name']       = $LANG['genericobject']["<type's name>"][2];
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['field']      = 'color';
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['input_type'] = 'dropdown';


The language variable must be defined in the language file (see explaination above).

  • Add a dropdown field that is assigned to an entity:
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['name']         = $LANG['genericobject']["<type's name>"][2];
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['field']        = 'color';
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['input_type']   = 'dropdown';
//Does the dropdown take care of entities ? (true/false)
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['entities_id']  = true;
//Can values be recursive ? (true/false, only taking in account if entities_id is set to true)
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['is_recursive'] = true;

Add a tree dropdown field

$GO_FIELDS['plugin_genericobject_mytypecolors_id']['name']       = $LANG['genericobject']["<type's name>"][2];
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['field']      = 'color';
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['input_type'] = 'dropdown';
//Is it a tree-dropdown, or a simple one ? (true/false)
$GO_FIELDS['plugin_genericobject_mytypecolors_id']['is_tree']    = true;


You can use at the same time the following parameters : entities_id, is_recursive, is_tree.

Add a dropdown field that is based on a GLPI-core object (user, location...)

$GO_FIELDS['users_id_passengers_id']['name']       = 'Passenger';
$GO_FIELDS['users_id_passengers_id']['input_type'] = 'dropdown';


Name between brackets ([]) MUST begin with users_id in order to be recognized as a field based on GLPI users’ list.

See file <GLPI_ROOT>/files/_plugins/genericobject/fields/field.constant.php to get a complete list of available fields.

Add a global dropdown

A global dropdown can be used in all itemtypes. A good example would be :

$GO_FIELDS['categories_id']['name']          = $LANG['common'][36];
$GO_FIELDS['categories_id']['input_type']    = 'dropdown';
$GO_FIELDS['categories_id']['dropdown_type'] = 'global';

A specific category table will be created for each itemtype. The table name and field name will the computed this way:

  • table : glpi_plugin_genericobject_<itemtypename>_category
  • field name : plugin_genericobject_<itemtype>categories_id

Add an integer field

$GO_FIELDS['testinteger']['name']       = 'testinteger';
$GO_FIELDS['testinteger']['input_type'] = 'integer';
$GO_FIELDS['testinteger']['min']        = 10; //not mandatory, by default 0
$GO_FIELDS['testinteger']['max']        = 40; //not mandatory, by default 100
$GO_FIELDS['testinteger']['step']       = 3; //not mandatory, by default 1

Add a text field

$GO_FIELDS['mytextfield']['name']       = 'My text field';
$GO_FIELDS['mytextfield']['input_type'] = 'text';

Changed in version 2.1.2: By adding the following argument, you can tell the plugin that this field can be automatically generated when using a template:

$GO_FIELDS['mytextfield']['autoname'] = true;

Add a Yes/No field

$GO_FIELDS['mybooleanfield']['name']       = 'My boolean field';
$GO_FIELDS['mybooleanfield']['input_type'] = 'bool';

Add a date field

$GO_FIELDS['creationdate']['name']       = $LANG['genericobject']['fields'][30];
$GO_FIELDS['creationdate']['input_type'] = 'date';

Add a date & time field

$GO_FIELDS['creationdate']['name']       = $LANG['genericobject']['fields'][30];
$GO_FIELDS['creationdate']['input_type'] = 'datetime';


If you don’t want a field to be modified using massive actions, add the following line to its definition:

$GO_FIELDS['myfield']['massiveaction'] = false;

Add global fields

To make your fields accessible to all itemtypes:

  • Create a file named <GLPI_ROOT>/files/_plugins/genericobject/fields/field.constant.php
  • Put your definitions in this file.

Setup Rights

You can define access rights for each object’s type, for each profile. Available options are:

  • right on the type: no access, read, write.
  • right to associate this type of object to tickets: yes, no.

To associate the rights you can either:

  • Use the Rights tab in the itemtype form.
  • Navigate to Administration > Profiles and administer the rights for each profile.

Use the new field

Activate the new type, it’s now ready to be used.

The new type is available for users in the Plugins > Objects management menu.

Regenerate files

Some files are automatically generated when you add a new type, or when you upgrade your plugin... But in some cases; it may be usefull to generate them again.

In order to achieve that; you will have to enable debug mode from your GLPI user profile; that will make a Debug tab appear on your object configuration. Just click the Regenerate files button, and you’re done!
