Display Products

Hi,

Well, if you're developing a component following the best practices of Joomla 3/4/5 development, you must have a XML file with the fields of your form using the types available in Joomla:
manual.joomla.org/docs/general-concepts/...lds/standard-fields/

And thus, you have 2 basic ways:
- You can create your own type of field based on the "list" type :
manual.joomla.org/docs/general-concepts/...-extending-listfield
In it, you can run your own MySQL query to load the products data from the hikashop_product table in order to populate the field.
- You can use the "sql" type:
manual.joomla.org/docs/general-concepts/.../standard-fields/sql
With it, you can directly provide the elements of a MySQL query to populate the field.

While these two approaches are fine, you'll quickly have a problem once the HikaShop you're taking the data from has more than a few thousand products because that's a lot of data to load from the database.

We actually had the same issue ourselves. For example, when you create a new menu item of the type "HikaShop product page", you need to select a product so that when the user click on the menu item he directly sees the product details page of that product.
And thus, we created our own type of form field called "selectproduct".
You need to add the field path "/components/com_hikashop/fields" to be able to use it.
And you can see an example of how it is used in the components/com_hikashop/views/product/tmpl/show.xml file:

								<field
												id="product_id"
												name="product_id"
												type="selectproduct"
												label="Select a product"
												description="Select here the product to display for the current link"
								/>

		$nameboxType = hikashop_get('type.namebox');
		$select = '<div style="height:130px; margin-left:150px;">' .
				$nameboxType->display(
					'jform[params][product_id]',
					$this->value,
					hikashopNameboxType::NAMEBOX_SINGLE,
					'product',
					array(
						'delete' => false,
						'default_text' => '<em>'.JText::_('HIKA_NONE').'</em>',
					)
				).
				'</div>';
