How to Insert Product Selection Widget into Backend Form?

Question

Magento has a widget where I can select a product. I need to embed it into my form. To be more clear I will provide screenshot:

From this widget I need only product id. I can see that I need something like this:

<id_path translate="label">
    <visible>1</visible>
    <required>1</required>
    <label>Product</label>
    <type>label</type>
    <helper_block>
        <type>adminhtml/catalog_product_widget_chooser</type>
        <data>
            <button translate="open">
                <open>Select Product...</open>
            </button>
        </data>
    </helper_block>
    <sort_order>10</sort_order>
</id_path>

But didn't found yet how to use it. I will be appreciate for any help.

Answer 1

I assume that you are creating an own widget - the following does not apply for plain admin forms.

You simply put that snipped in the <parameters> section of your widget configuration (`widget.xml').

When the user chooses a product, the parameter id_path would be set in your widget.

Inside of your widget block you can get this parameter like this:

$this->getData('id_path');

The ID path contains stuff like 'product/123' - you probably only want the product id:

list($dummy, $productId) = explode("/", $this->getData('id_path'))

Answer 2

This is what I was looking for:

$product1Link = $fieldset->addField('product1_link', 'label', array(
        'name' => 'product1_link',
        'label' => Mage::helper('abc_productbundles')->__('Product 1'),
        'class' => 'widget-option',
        'value' => $model->getProduct1Link(),
        'required' => true,
    ));

$model->unsProduct1Link();
$helperBlock = $this->getLayout()->createBlock('adminhtml/catalog_product_widget_chooser');
if ($helperBlock instanceof Varien_Object) {
    $helperBlock->setConfig($this->getChooserConfig())
        ->setFieldsetId($fieldset->getId())
        ->setTranslationHelper(Mage::helper('abc_productbundles'))
        ->prepareElementHtml($product1Link);
}
