Reads in the HTML file or free markup and prints its contents on a page.

Kuvaus

The tags that print lists also have the helper attribute that works almost in the same way as the {Helper} tag.

See also the instructions for formatting lists by using the helper attribute.

Näkyvyys

Toimii näkyvyydessä: globaali

Tags with global scope can be used on any template and in any tag.

Content reuse on multiple pages by using the {Helper} tag

<header>
    <div class="logo">
        {Logo}
    </div>
    <nav>
        {Categories}
    </nav>
</header>

The above file contains the header section used by every theme page, where the company logo and product category navigation are printed by using the {Logo} and the {Categories} tags respectively.

The file can be found in the theme folder helpers under the name header.html.

{Helper(
    file: 'helpers/header'
)}

The header.html file can be retrieved by using the above markup. Note that the file path indicated as the value of the file attribute doesn't contain the file extension.

Printing a single product by using the {Helper} tag

If you want to print the files of a single product by using the {Helper} tag, save the product tags that print the following product details in the file to be printed:

<div>
    <h2>{ProductName}</h2>
    <div>
        {ProductPrices}
    </div>
    <div>
        {ProductDescription}
    </div>
</div>

The sample file above is located in the theme folder /helpers under the name promotuote.html:

{Helper(
    file: 'helpers/promotuote',
    product: 6
)}

In such case, the selected product's ID number and the location of the file to be printed are indicated as the values of the product and file attributes of the {Helper} tag, respectively.

In the example, the tags in the file to be printed print details of the product whose ID number is 6.

Printing products belonging to a product category by using the {Helper} tag

Where necessary, you can use the {Helper} tag to print a list of products belonging to a selected category. In such case, you can use e.g. the {CategoryProducts} tag in the file to be printed to print the product list.

<div>
    <h2>{CategoryName}</h2>
    <div>{CategoryDescription}</div>
    <div>
        {CategoryProducts(
            helper: 'helpers/listproduct'
        )}
    </div>
</div>

The above HTML and Interface markup is saved in the helpers/promo-category.html file.

In the example, the tag that prints the list is used with the helper attribute, which is used for setting the contents of the helpers/listproduct.html file to print the markup of a single product included on the list.

{Helper(
    file: 'helpers/promo-category',
    category: 7
)}

The Interface markup prints the name, description and products of the product category whose ID number is 7.

Printing contents only for customers belonging to specific customer groups

The contents that should be available only to specific customer groups are saved to a separate file in the /helpers folder of the online store's theme.

<div>
    <h2>Only for resellers</h2>
    <p>This content is displayed only to logged in users who belong to the reseller customer group.</p>
</div>

The example contains only HTML contents but the file can of course contain Interface markup too.

{Helper(
    file: 'helpers/reseller-content',
    case: 'CustomerGroup-3'
)}

The contents are printed by using the {Helper} tag with 'CustomerGroup-n' as the value of the case attribute, where n is the ID number of the selected customer group.
