New module extension

Wednesday 04 May 2011 2:28:28 pm

Hi,

I'm developing an extension that updates an attribute of an object. I read the tutorial and explains how to insert and query data from the database, but doesn't explain how to update.

I've created the module, function and class, but I'm blocked. In ezpersistentobject class ther is a function updateObjectList, but I have to pass a variable $parameters. My code is this:

exempleclass.php

class ExempleClass extends eZPersistentObject {
    
    function exempleclass( $row ) {
        
        $this->eZPersistenObject( $row );        
    }
    
    function definition() {
        
        return array( 'fields' => array( 'id' => array( 'name' => 'id', 
                                                        'datatype' => 'integer', 
                                                        'default' => 0, 
                                                        'required' => true ),
 
                                         'user_id' => array( 'name' => 'version', 
                                                             'datatype' => 'integer', 
                                                             'default' => 0, 
                                                             'required' => true ),
 
                                         'created' => array( 'name' => 'data_int', 
                                                             'datatype' => 'integer', 
                                                             'default' => 0, 
                                                             'required' => false ) ),  
                      'class_name' => 'exempleclass', 
                      'name' => 'ezcontentobject_attribute' ); 
    }
    
    function update( $attribute_id, $version, $value ) {
        
        $row = array( 'definition' => array( 'name' => 'ezcontentobject_attribute',
                                             'fields' => array( ),
                                             'key' ),
                      'update_fields' => array( 'data_int' => $value ),
                      'conditions' => array( 'id' => $attribute_id,
                                             'version' => $version ) );
        
        return new exempleclass( $row );
    }
}

exemplefunction.php

include_once 'extension/example/classes/exempleclass.php';

$Module = $Params['Module'];

$attributeId= $Params['AttributeId']; 
$version = $Params['Version'];

$ExampleClass= ExampleClass::update( $attributeId, $version, 23 );

How do I call the function to update?

Thanks,

David

Ok, but if I call the store function I'll be making a new INSERT. I want to do an UPDATE.

Ah!

Ok, thanks. I didn't understand it.

You can find some usefull tips about it here:

• http://share.ez.no/forums/developer/how-to-edit-store-user-attributes-within-a-extension

The last comment in the first thread is the simplest, but I think it won't clear the cache.

As for the detailed docs about it I don't think there is any, you'll have to dig and try a little bit until you figure out what's the best for you.
