How to create ezcontentobject programmatically

How to create ezcontentobject programmatically

Thursday 27 February 2003 12:13:04 pm - 8 replies

Imagine I have done "custom class" tutorial and have created a class "Car". How do I create objects of this class using PHP? I need to import data from old database into ez publish. Spent a week digging in PHP code but no result.

Could anybody post a sample code - how to create an instance of custom class, populate attributes and store into persistent storage.

Thank you!

Thanks, Bruce, but this import/export modules is very complicated for me (i just beginner), so i'll be very happy if you'll post just sample how to create content class with one attribute happy.gif Emoticon

Hi,

Here is some sample code to create a user. I don't remember where I took this from ...

<?php 

include_once( 'kernel/classes/ezcontentobject.php' ); 
include_once( 'lib/ezlocale/classes/ezdatetime.php' ); 
  
// Testuser definition 
$firstName = "Hugo"; 
$lastName = "Heise"; 
$email = "hugo.heise@hoppecke.com"; 
$login= "h-waldmann"; 



echo "creating Account: ".$login." - ".$firstName." ".$lastName." / ".$email."<br>"; 

$userClassID = 4; 
$class =& eZContentClass::fetch( $userClassID ); 

$creatorID = 426; // 426 = N.Leutner 
$groupNodeID = 140; 

$contentObject =& $class->instantiate( $creatorID, 1 ); 
  
// Insert into Table eznode_assignment 
$nodeAssignment =& eZNodeAssignment::create( array( 
                                                 'contentobject_id' => $contentObject->attribute( 'id' ), 
                                                 'contentobject_version' => $contentObject->attribute( 'current_version' ),

                                                 'parent_node' => $groupNodeID, 
                                                 'sort_field' => 9, 
                                                 'is_main' => 1 
                                                 ) 
                                             ); 
$nodeAssignment->store(); 
  

// Insert into Table ezcontentobject_version  
$version =& $contentObject->version( 1 ); 
$version->setAttribute( 'modified', eZDateTime::currentTimeStamp() ); 
$version->setAttribute( 'status', EZ_VERSION_STATUS_DRAFT ); 
$version->store(); 



// Inserts into Table ezcontentobject_attribute 

    // Attribute1 = parent attribute 
    $contentObjectID = $contentObject->attribute( 'id' ); 
    $contentObjectAttributes =& $version->contentObjectAttributes(); 

    // Attribute2 = firstname 
    $contentObjectAttributes[0]->setAttribute( 'data_text', $firstName ); 
    $contentObjectAttributes[0]->store(); 

    // Attribute3 = lastname 
    $contentObjectAttributes[1]->setAttribute( 'data_text', $lastName ); 
    $contentObjectAttributes[1]->store(); 



// Inserts into Table ezuser 

    // Create user by parent attribute ID 
    $user =& eZUser::create( $contentObjectID ); 

    // Create password with 8 Charakters 
    $password = eZUser::createPassword( 8, $firstName . $lastName . $email ); 
    echo "Password lautet: ".$password."<br>"; 
    
    // Create passwordhash 
    $hash = $user->createHash( $login, $password, eZUser::site(), eZUser::hashType() ); 

    // Set attributes 
    $user->setAttribute('login', $login ); 
    $user->setAttribute('email', $email); 
    $user->setAttribute('password_hash', $hash ); 
    $user->setAttribute('password_hash_type', 2 ); 
    $user->store(); 

// Publish user 
// This function returns the error: Cannot execute operation 'publish' in module 'content', 
// no valid dataeZOperationHandler::execute

include_once( 'lib/ezutils/classes/ezoperationhandler.php' ); 
$operationResult = eZOperationHandler::execute( 'content', 'publish', array( 'object_id' => $contentObjectID, 
                                                                             'version' => 1 ) ); 

?>

And another sample code to create a folder (the method to populate the attributes is better in the previous code)

<?

function createFolderObject($user, $sectionID, $userNodeID=2, $folderTitle="No title")
{
  $folderClassID=1;
  
  $class =& eZContentClass::fetch( $folderClassID );
  $folderContentObject =& $class->instantiate( $user->id(), $sectionID );
  
  // Create a node for the object in the tree.
  $nodeAssignment =& eZNodeAssignment::create( array(
                         'contentobject_id' => $folderContentObject->attribute( 'id' ),
                         'contentobject_version' => 1,
                         'parent_node' => $userNodeID,
                         'sort_field' => 2, //Published
                         'sort_order' => 1, //Descending
                         'is_main' => 1));
  $nodeAssignment->store();
    
  // Set a status for the content object version
  $folderContentObjectVersion =& $folderContentObject->version($folderContentObject->attribute( 'current_version' ) );
  $folderContentObjectVersion->setAttribute( 'status', EZ_VERSION_STATUS_DRAFT);
  $folderContentObjectVersion->store();

  // Set the title of the folder.
  $folderContentObjectAttributes =& $folderContentObjectVersion->contentObjectAttributes();
  foreach ($folderContentObjectAttributes as $folderAttribute)
  {
    // Each attribute has an attribute called 'identifier' that identifies it.    

    if ($folderAttribute->attribute("contentclass_attribute_identifier") == "title")
    {
      $folderAttribute->setAttribute("data_text",$folderTitle);
      $folderAttribute->store();
    }
  }
      
  // Now publish the object.
  $operationResult = eZOperationHandler::execute( 'content', 'publish',
                          array( 'object_id' => $folderContentObject->attribute( 'id' ),
                                 'version' => $folderContentObject->attribute('current_version' ) ) );
  
  return;
}

?>

I have some code before... but i have one error too:
Fatal error: Call to a member function on a non-object in C:\ezpublish\ezpublish\bin\php\test.php on line 22

<b>line 22:</b> <i>$contentObject =& $class->instantiate( $creatorID, 1 );</i>

what it's mean?

Sorry Guys!!!

the bug was in another place->
when i call:$class =& eZContentClass::fetch( $contentClassID );

fetch does not return object...
this bug was closed and work in ez here
( http://ez.no/community/bugs/ezcon...return_an_object_for_certain_classes )

the problem was db connection.
EVERY THING OK! I was trying execute this php-file from shell and nothing work... now i try execute it like cron and everything is working perfectly!!!

You must use this code in eZ Publish context, either in a cronjob or in a custom module. You should have a look at the doc blunk.gif Emoticon
