Aggiunta di colonne alla griglia del cliente mediante l'osservatore o sostituzione della griglia del cliente

Sto affrontando il problema di aggiungere una colonna sulla griglia del cliente e mostrare i valori in quella colonna.

Ecco il codice osservatore che ho cercato di mostrare la colonna: -

if ($block->getType() == 'adminhtml/customer_grid') {
          $customer = $observer->getCustomer();
          $collection = Mage::getResourceModel('customer/customer_collection');
        $block->addColumnAfter('mobile', array(
                'header'    => 'Mobile No.',
                'type'      => 'text',
                'index'     => 'mobile',
            ), 'email');
        }   

Questo aggiunge la colonna ma nessun valore è mostrato sotto quello.

Per aggiungere una colonna alla griglia del cliente, è necessario sovrascrivere 2 elementi nel blocco Mage_Adminhtml_Block_Customer_Grid .

• _prepareCollection - per aggiungere il tuo attributo alla raccolta
• _prepareColumns - per aggiungere la colonna nella griglia.

Per questo dovresti creare una nuova estensione. Chiamiamolo Easylife_Customer. Per questo avrai bisogno dei seguenti file:
app/etc/module/Easylife_Customer.xml- il file di dichiarazione

<?xml version="1.0"?>
<config>
    <modules>
        <Easylife_Customer>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Customer /><!-- your module should depend on Mage_Customer -->
                <Mage_Adminhtml /><!-- your module should depend on Mage_Adminhtml also -->
            </depends>
        </Easylife_Customer>
    </modules>
</config>

app/code/local/Easylife/Customer/etc/config.xml - il file di configurazione

<?xml version="1.0"?>
<config>
    <modules>
        <Easylife_Customer>
            <version>0.0.1</version>
        </Easylife_Customer>
    </modules>
    <global>
        <blocks>
            <adminhtml>
                <rewrite>
                    <customer_grid>Easylife_Customer_Block_Adminhtml_Customer_Grid</customer_grid><!-- rewrite the customer grid -->
                </rewrite>
            </adminhtml>
        </blocks>
    </global>
</config>

app/code/local/Easylife/Customer/Block/Adminhtml/Customer/Grid.php- la tua versione della griglia del cliente. Leggi i miei commenti nel codice:

<?php

    /**
     * override the _prepareCollection to add an other attribute to the grid

    protected function _prepareCollection(){
        $collection = Mage::getResourceModel('customer/customer_collection')
            ->addNameToSelect()
            ->addAttributeToSelect('email')

            ->addAttributeToSelect('group_id')
            //if the attribute belongs to the customer, use the line below
            ->addAttributeToSelect('mobile')

        $this->setCollection($collection);
        //code from Mage_Adminhtml_Block_Widget_Grid::_prepareCollection()
        //since calling parent::_prepareCollection will render the code above useless
        //and you cannot call in php parent::parent::_prepareCollection()
        if ($this->getCollection()) {

            $this->_preparePage();

            $columnId = $this->getParam($this->getVarNameSort(), $this->_defaultSort);
            $dir      = $this->getParam($this->getVarNameDir(), $this->_defaultDir);

            if (is_string($filter)) {
                $data = $this->helper('adminhtml')->prepareFilterString($filter);
                $this->_setFilterValues($data);
            }
            else if ($filter && is_array($filter)) {
                $this->_setFilterValues($filter);
            }
            else if(0 !== sizeof($this->_defaultFilter)) {
                $this->_setFilterValues($this->_defaultFilter);
            }

            if (isset($this->_columns[$columnId]) && $this->_columns[$columnId]->getIndex()) {
                $dir = (strtolower($dir)=='desc') ? 'desc' : 'asc';
                $this->_columns[$columnId]->setDir($dir);
                $this->_setCollectionOrder($this->_columns[$columnId]);
            }

            if (!$this->_isExport) {
                $this->getCollection()->load();
                $this->_afterLoadCollection();

        ),'email');
        return parent::_prepareColumns();

}

Svuota la cache e dovresti essere pronto.

La via degli osservatori:

Dichiara 2 osservatori nel tuo file config.xml: uno per aggiungere la colonna al blocco della griglia e l'altro per caricare i dati dall'attributo corrispondente:

<adminhtml>
    <events>
        <core_block_abstract_to_html_before>
            <observers>
                <{observer_name}>
                    <type>singleton</type>
                    <class>{namespace}_{module}/observer</class>
                    <method>beforeBlockToHtml</method>
                </{observer_name}>
            </observers>
        </core_block_abstract_to_html_before>
        <eav_collection_abstract_load_before>
            <observers>
                <{observer_name}>
                    <class>{namespace}_{module}/observer</class>
                    <method>beforeCollectionLoad</method>
                </{observer_name}>
            </observers>
        </eav_collection_abstract_load_before>
    </events>
</adminhtml>

Crea una classe Observer con i metodi appropriati:

class {Namespace}_{Module}_Model_Observer
{
    public function beforeBlockToHtml(Varien_Event_Observer $observer)
    {
        $grid = $observer->getBlock();

        /**
         * Mage_Adminhtml_Block_Customer_Grid
         */
        if ($grid instanceof Mage_Adminhtml_Block_Customer_Grid) {
            $grid->addColumnAfter(
                '{column_code}',
                array(
                    'header' => Mage::helper('{Module}_customer')->__('{{column_name}}'),
                    'index'  => '{column_code}'
                ),
                'entity_id'
            );
        }
    }

    public function beforeCollectionLoad(Varien_Event_Observer $observer)
    {
        $collection = $observer->getCollection();
        if (!isset($collection)) {
            return;
        }

        /**
         * Mage_Customer_Model_Resource_Customer_Collection
         */
        if ($collection instanceof Mage_Customer_Model_Resource_Customer_Collection) {
            /* @var $collection Mage_Customer_Model_Resource_Customer_Collection */
            $collection->addAttributeToSelect('{attribute_code}');
        }
    }
}

Rispondo al commento di Alex:

Per esportare anche in CSV usa

core_block_abstract_prepare_layout_before

invece di

core_block_abstract_to_html_before

Supponendo che $blocksia un'istanza di Mage_Adminhtml_Block_Customer_Gridallora

$block->getCollection()dovrebbe restituire una raccolta clienti utilizzata nella griglia che è un'istanza di Mage_Customer_Model_Resource_Customer_Collection. Quando guardi il codice in Mage_Adminhtml_Block_Customer_Grid::_prepareCollection(), vedrai come puoi aggiungere un attributo a quella raccolta.

Dovrebbe essere (anche se non testato)

supponendo che sia stato aggiunto un attributo mobile all'entità cliente

$block->getCollection()
      ->addAttributeToSelect('mobile');

o se il cellulare è e l'attributo aggiunto all'entità dell'indirizzo di fatturazione

$block->getCollection()
      ->joinAttriubte('mobile','customer_address/mobile','defaul_billing',null,'left');

Un altro modo:

Riscrivi il blocco della griglia del cliente con il modulo personalizzato e utilizza la setCollection()funzione per recuperare l'attributo personalizzato.

app / codice / [locale o comunità] /YourCompany/YourModule/etc/config.xml

        // your field/attribute to fetch, assuming it to be 'mobile'
        $collection->addAttributeToSelect('mobile'); 
        parent::setCollection($collection);
    }

    protected function _prepareColumns()
    {
        parent::_prepareColumns();

        $this->addColumn('mobile', array(
                'header'=> Mage::helper('customer')->__('Mobile'),
                'index' => 'mobile',
                'type'  => 'text',
                'width' => '100px',
        ));

        // show your new column named 'mobile' after ZIP column
        $this->addColumnsOrder('mobile', 'billing_postcode');

        return parent::_prepareColumns();
    }
}

Avevo bisogno di rimuovere alcune colonne predefinite e aggiungere colonne aggiuntive nella griglia del cliente. Ho deciso di rendere configurabili le colonne. Per prima cosa ho aggiunto 2 caselle multiselect in system.xml :

<config>
    <sections>
        <extendedcustomer translate="label" module="extendedcustomer">
            <label>Extended Customer</label>
            <tab>customer</tab>
            <sort_order>100</sort_order>
            <show_in_default>1</show_in_default>
            <show_in_website>1</show_in_website>
            <show_in_store>1</show_in_store>
            <groups>
                <manage_grid translate="label">
                    <label>Manage Customer Grid in Backend</label>
                    <frontend_type>text</frontend_type>
                    <sort_order>10</sort_order>
                    <show_in_default>1</show_in_default>
                    <show_in_website>1</show_in_website>
                    <show_in_store>1</show_in_store>
                    <fields>
                        <remove translate="label">
                            <label>Remove Columns</label>
                            <frontend_type>multiselect</frontend_type>
                            <source_model>extendedcustomer/source_gridColumn</source_model>
                            <sort_order>10</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </remove>
                        <add translate="label">
                            <label>Add Columns</label>
                            <frontend_type>multiselect</frontend_type>
                            <source_model>extendedcustomer/source_attributeCode</source_model>
                            <sort_order>20</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </add>                       
                    </fields>
                </manage_grid>
            </groups>
        </extendedcustomer>
    </sections>
</config>

I modelli sorgente sono semplici:

class SomeCo_ExtendedCustomer_Model_Source_GridColumn
{
    public function toOptionArray()
    {     
        return [
            ['value' => 'name', 'label' => 'Name'],
            ['value' => 'email', 'label' => 'Email'],
            ['value' => 'group', 'label' => 'Group'],
            ['value' => 'billing_telephone', 'label' => 'Telephone'],
            ['value' => 'billing_postcode', 'label' => 'ZIP'],
            ['value' => 'billing_country_id', 'label' => 'Country'],
            ['value' => 'billing_region', 'label' => 'State/Province'],
            ['value' => 'customer_since', 'label' => 'Customer Since'],
            ['value' => 'website_id', 'label' => 'Website'],
            ['value' => 'action', 'label' => 'Action']
        ];
    }
}

Il secondo modello di origine

class SomeCo_ExtendedCustomer_Model_Source_AttributeCode
{
    public function toOptionArray()
    {     
        $collection = Mage::getResourceModel('customer/attribute_collection')
            ->addFieldToSelect(['attribute_code', 'frontend_label'])
            ->addFieldToFilter('frontend_label', ['notnull'=>'notnull'])
            ->addFieldToFilter('is_user_defined', 1);
        $options = [];
        foreach ($collection as $item) {
            $options[] = [
                'value'     => $item->getData('attribute_code'),
                'label'     => $item->getData('frontend_label')
            ];
        }
        return $options;
    }
}

Quindi sovrascrivere la classe della griglia:

class SomeCo_ExtendedCustomer_Block_Adminhtml_Customer_Grid extends Mage_Adminhtml_Block_Customer_Grid
{
    public function __construct()
    {
        parent::__construct();
        if ($remove = Mage::getStoreConfig('extendedcustomer/manage_grid/remove')) {
            $remove = explode(',', $remove);
        } else {
            $remove = false;
        }
        $this->setRemoveList($remove);

        if ($add = Mage::getStoreConfig('extendedcustomer/manage_grid/add')) {
            $add = explode(',', $add);
        } else {
            $add = false;
        }
        $this->setAddList($add);
    }

    protected function _prepareCollection()
    {
        if ($remove = $this->getRemoveList()) {
            $collection = Mage::getResourceModel('customer/customer_collection');
            if (!in_array('name', $remove)) {
                $collection->addNameToSelect();
            }
            foreach (['postcode', 'city', 'telephone', 'region', 'country_id'] as $suffix) {
                if (!in_array('billing_'.$suffix, $remove)) {
                    $collection->joinAttribute('billing_'.$suffix, 'customer_address/'.$suffix, 'default_billing', null, 'left');
                }
            }
        } else {
            $collection = Mage::getResourceModel('customer/customer_collection')
                ->addNameToSelect()
                //->addAttributeToSelect('email') // static attributes are added by default
                //->addAttributeToSelect('created_at')
                //->addAttributeToSelect('group_id')
                ->joinAttribute('billing_postcode', 'customer_address/postcode', 'default_billing', null, 'left')
                ->joinAttribute('billing_city', 'customer_address/city', 'default_billing', null, 'left')
                ->joinAttribute('billing_telephone', 'customer_address/telephone', 'default_billing', null, 'left')
                ->joinAttribute('billing_region', 'customer_address/region', 'default_billing', null, 'left')
                ->joinAttribute('billing_country_id', 'customer_address/country_id', 'default_billing', null, 'left');
        }

        if ($add = $this->getAddList()) {
            $collection->addAttributeToSelect($add);
        }

        $this->setCollection($collection);

        return Mage_Adminhtml_Block_Widget_Grid::_prepareCollection(); // call grandParent
    }

    protected function _prepareColumns()
    {
        $this->addColumn('entity_id', array(
            'header'    => Mage::helper('customer')->__('ID'),
            'width'     => '50px',
            'index'     => 'entity_id',
            'type'  => 'number',
        ));

        $remove = $this->getRemoveList();

        if (!$remove || !in_array('name', $remove)) {           
            $this->addColumn('name', array(
                'header'    => Mage::helper('customer')->__('Name'),
                'index'     => 'name'
            ));
        }

        if ($add = $this->getAddList()) {
            $collection = Mage::getResourceModel('customer/attribute_collection')
                ->addFieldToSelect(['attribute_code', 'frontend_label', 'source_model'])
                ->addFieldToFilter('attribute_code', ['in' => $add]);
            foreach ($collection as $item) {
                if ($source = $item->getSourceModel()) {
                    $this->addColumn($item->getAttributeCode(), array(
                        'header'    =>  $item->getFrontendLabel(),

                        'type'      =>  'options',
