The code on page 8 which reads:
-----------------------------------------------

class JACExtensionData extends eZPersistentObject
{
/*!
Konstruktor
*/
function JACExtensionData( $row )
{
$this->eZPersistentObject( $row );
}

/*!
Definition of the data object structure /of the structure of the database table
*/
function definition()
---------------------------------------------

In eZ Publish 4.x should be:
-------------------------------------------

class JACExtensionData extends eZPersistentObject
{
/*!
Konstruktor
*/
function JACExtensionData( $row )
{
$this->eZPersistentObject( $row );
}

/*!
Definition of the data object structure /of the structure of the database table
*/
static function definition()
------------------------------------------------

Then it works!

After adding the new function_definition.php file (page 9 - Template Fetch Functions) update the extension auto-load array by clicking the "Regenerate autoload arrays for extensions" button in the Admin panel Settings -> Extensions.

The reply has been removed because of violation of forum rules.

After clearing all the cache I still get the message:

No template could be loaded for "modul1/list.tpl" using resource "design"

please help

For an extension that adds one or more tables to the db, it is important to create a share/db_schema.dba file where these new tables are described.

This way when the admin goes to the "Setup/Upgrade Check/Check db consistency" page

- he will note get a suggestion to drop the table

- he will get a suggestion with the sql command to create the table if the table does not exist

This is true since eZP 4.3

The format for db_schema.dba is propietary to eZ. You can find examples in ezfind, ezflow and other extensions from eZ Systems

To generate that file you can use the ezsqldumpschema.php script. Take care: right now it will create a file with the definition of the whole db, so you should either use it in a db where you only have your new table(s) or clean up by hand the generated .dba file

Hey Gaetano, thanks for help!

To really be a mirror for best practice, then code examples should add phpdoc and use php5 features like __construct and so on, eg:

/**
 * JACExtensionData does....
 */
class JACExtensionData extends eZPersistentObject
{
   /**
    * Constructor
    *
    * @param array $row Hash of attributes for new <span class="Apple-style-span" style="font-size: 13px; " mce_fixed="1">JACExtensionData</span> <span class="Apple-style-span" style="font-size: 13px; " mce_fixed="1"><span>object</span></span>
    */ 
    function __construct( $row )
    {
        parent::__construct( $row );
    }
 
   /**
    * Definition of the data object structure /of the structure of the database table
    *
    * @return array Hashed array with table definition of this p<span class="Apple-style-span" style="font-size: 13px; " mce_fixed="1">ersistent object</span>
    */ 
    static function definition()

Additionally, member variables should probably be protected/private to make sure attribute() function is used outside the class.

Thanks André. I just fixed this.

Hi Guys!

Is there a way to create a custom locale file (eng-US@custom.ini) inside an extension?

Any help will be appreciated!

I thought best practice was to put operators in a separate /operators folder. Is that not the case anymore? Or am I simply mistaken?

Template operators ? Placing them in the 'autoloads' directory, at the root of the given extension directory, is the usual practice.

Cheers,

I downloaded eZPublis 4.3 and there is a small mistake in example above.

When registering template operator in eztemplateautoload.php we need to specify script variable:

$eZTemplateOperatorArray[] = array( 'script' => 'extension/jaxectension/autoloads/jacoperator.php',
                                    'class' => 'JACOperator',
                                    'operator_names' => array( 'jac' ) );

This worked for me

I have followed your instructions but I get the error:

Undefined module: modul1

What can I have done wrong?

The only difference I see is that I have an installation of eZ 4.7 Demo. So the URL is http://myez.localhost/index.php/ezdemo_site/modul1/list/table/5/%28param4%29/141

There is an error in the tutorial! Argh. the module.php should be in modul1 folder

Quote from Andreas Wiik :

Ops, it is correct here, but wrong here: http://doc.ez.no/Tutorials/Develo...-extensions/Creating-a-new-extension

Hi Andreas,

sorry for that. I will inform the ez responsable for that to fix the ez doc.

Cheers Felix

=> the doc is fixed now

I'm unable to make the fetch functions work. I get an error:

Missing function definition file for module: modul1

But I have created function_defintion.php in modules/modul1

The template operators do work though.

That was my mistake Typo
