问题


I'm working with custom module for the magento backend, in this filter not working when using filter calback! Can anyone suggest me? Thanks!

I have tried some codes like this,

Grid.php

protected function _prepareCollection()
    {
     $collection = Mage::getModel('listings/listings')->getCollection();
     $this->setCollection($collection);
       return parent::_prepareCollection();
    }
protected function _prepareColumns()
    {     
        $this->addColumn("item_id", array(
            "header" => Mage::helper("linkmanagement")->__("ID"),
            "align" => "center",
            "type" => "number",
            "index" => "item_id",

        ));

        $this->addColumn("title", array(
            "header" => Mage::helper("linkmanagement")->__("Title"),
            "index" => "title"
        ));

        $this->addColumn("cat_ids", array(
            "header" => Mage::helper("linkmanagement")->__("Cat ID"),
            "align" => "center",
            "index" => "cat_ids",
            "renderer" => 'Sathish_Linkmanagement_Block_Adminhtml_Linkmanagement_Renderer_Categories',
            'filter_condition_callback' => array($this, '_categoriesFilter')
        ));

        $this->addColumn("url_key", array(
            "header" => Mage::helper("linkmanagement")->__("URL"),
            "index" => "url_key",
            "width" => "200px",
        ));

        $this->addColumn('status',
            array(
                'header' => Mage::helper('linkmanagement')->__('Status'),
                'index' => 'status',
                'type' => 'options',
                'options' => array('1' => Mage::helper('linkmanagement')->__('Active'),
                    '0' => Mage::helper('linkmanagement')->__('Inactive')),
            )
        );

        return parent::_prepareColumns();
    }

callback function

protected function _categoriesFilter($collection, $column)
    {
        if (!$value = $column->getFilter()->getValue()) {
            return $this;
        }

        $this->getCollection()->getSelect()->where(
            "cat_ids ?"
            , "%$value%");
        return $this;
    }

Categories.php

class Sathish_Linkmanagement_Block_Adminhtml_Linkmanagement_Renderer_Categories extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{

    public function render(Varien_Object $row)
    {
        $value =  $row->getData($this->getColumn()->getIndex());
        // $value = 38,92
        $value = explode(',',$value);
        $collection = Mage::getModel("categories/categories")->getCollection()->addFieldToFilter('category_id',$value)->getData();
        foreach($collection as $col){
            $result[] = $col['title'];
        }
        $result = implode(',', $result);// $result = schools,colleges
        return $result;
    }
}

Note: Renderer working fine., only filter callback function is not working!!!


回答1:


I checked your example with my own renderer and tried to check your callback.

Replace in your callback method

$this->getCollection()->getSelect()

with

$collection

Here are my pieces of advice:


Magento filter assumes not 100% similarity. I mean that if you want to apply filter you should use construction:

where("cat_ids LIKE ?", "%$value%");

I still don't understand answer on question below:

Define not working. Is the callback ever being called? Is the callback code having no affect on the results? – Lee Saferite 1 hour ago

Put Mage::log('blabla', false, 'grid.log', true); at the beginning of the callback method. Then check this log file. If it's not empty - your method calls successfully.


If your method calls - try to

Mage::log($collection->getSelectSQL(1), false, 'grid.log', true);

before and after filter applying. And try to run these queries in phpmyadmin. Check the result


Try to apply these changes inside Mage_Adminhtml_Block_Sales_Order_Grid class

Here what I did:

    $this->addColumn("cat_ids", array(
        "header" => Mage::helper('sales')->__('Ship to Name'),
        "align" => "center",
        "index" => "grand_total",
        "renderer" => "My_Class_.....",
        "filter_condition_callback" => array($this, '_categoriesFilter')
    ));

....

protected function _categoriesFilter($collection, $column)
{
    if (!$value = $column->getFilter()->getValue()) {
        return $this;
    }

    $collection->getSelect()->where(
        "status LIKE ?", "%$value%"
    );

    return $this;
}

...

public function render(Varien_Object $row)
{
    $value =  $row->getData('increment_id') . $row->getData('status');
    return $value;
}
