Craft Behaviors Reference

This page is the detailed reference for all yStore Twig functions. For a quick-reference overview with usage examples, see Twig Reference.

Craft CMS offers a flexible way to extend its core functionalities through behaviors, and our plugin leverages this capability to enhance Twig templates with custom methods and properties. By integrating custom behaviors, you can add new, dynamic functionalities to Twig, making it more powerful and tailored to your specific needs.

Product Functions​

yuiProducts​

Returns a new ProductQuery instance with customizable selection criteria.

Parameters:

  • selectFields [Array] - A list of fields which need to be selected. If empty, all fields will be listed
  • criteria [Object] - A list of criteria that will be applied on the query.
  • orderBy [Object] - A list of order requirements. The default order is: ID DESC {id: 3}
  • limit [Integer] - The limit how many rows the query should return. Leave empty or null to return all data
  • with [Object] - Its highly recommended that use this eager-loading functionality
info

You can find the usage example of this function in the Product Listing section.

Formatting Functions​

formatAddress​

Formats an address for display.

Parameters:

  • address (the address to be formatted)

Generates a <link> tag for a CSS file. If a version parameter is provided, it appends the version number to the CSS file's URL as a query string, in the format (?version={version}), allowing for cache busting or specifying a particular version of the CSS file to ensure the browser loads the most recent or intended version of the stylesheets. This is particularly useful when deploying updates or managing multiple versions of assets across different environments.

Parameters:

  • string $filePath (the path to the CSS file)
  • string $version (the version of the CSS file)
danger

Avoid using random numbers or timestamps as the version value for CSS files, even in development mode. This practice prevents the browser from caching the CSS file properly because each version will appear unique (due to the changing random number or timestamp), causing the browser to treat it as a new resource with every request. Instead, use versioning based on actual updates (e.g., a version number or commit hash) to ensure proper caching while still allowing the browser to detect when a file has changed, improving performance and reducing unnecessary re-downloads of unchanged resources.

getCssStyleContent​

The getCssStyleContent function retrieves the content of a CSS file and is optimized for performance by caching the content in production environments. This function is particularly useful for injecting critical CSS directly into your Twig templates, reducing the number of HTTP requests and improving the initial load time of your pages.

Parameters:

  • cssSource [String] - The relative path to the CSS file in your project.

Usage Example:​

To include inline CSS in your Twig template, you can use the getCssStyleContent function as follows:

<style title="Inline Styles">
    {{ craft.getCssStyleContent('assets/css/critical/catalog')|raw }}        
</style>

Best Practices

Minifying CSS:

Ensure that your CSS files are minified to reduce their size before deploying them to production. Smaller files will load faster and reduce the time needed to parse and apply styles.

Injecting Critical CSS:

Use this function within the {% head %} block in Twig to ensure that critical CSS is loaded early in the page rendering process. This approach helps improve the perceived performance by styling the page as soon as possible.

{% block head %}
    <style title="Inline Styles">
        {{ craft.getCssStyleContent('assets/css/critical/contact')|raw }}
    </style>
{% endblock %}

getJsContent​

Retrieves the content of a JavaScript file.

Parameters:

  • string $cssSource (the source of the JavaScript file)

buildFilterQuery​

Builds a filter query based on specified parameters.

buildParamsQuery​

Builds a query string based on specified parameters.

buildRelatedToQuery​

Builds a related-to query for fetching related entries.

getTotalLabels​

Retrieves labels for totals based on the specified type.

Parameters:

  • string $type (the type of total label to retrieve)

getSectionData​

Retrieves data for a specific section.

getAgreementLabel​

Retrieves the label for an agreement.

renderFormToken​

The renderFormToken function renders the CSRF token asynchronously, ensuring that it is always up-to-date and secure.

Usage Example:​

 {{ craft.renderFormToken()|raw }}
note

You must use the raw filter to render the token properly.

isMinifyEnabled​

The isMinifyEnabled function returns true when the minification plugin is enabled. We use the Minify Plugin from the Craft CMS store.

Usage Example:​

{% if isMinifyEnabled() %}
    {% minify %}
        // Your code            
    {% endminify %}
{% endif %}
tip

You can use this approach to minify inline CSS/JS codes as well, using the {% minify css %} or {% minify js %} wrappers. This is only recommended if you do not already minify your CSS/JS by default.

Tax Functions​

getTaxPercentById​

Retrieves the tax percentage for a given tax category.

Parameters:

  • int $taxCategoryId (the ID of the tax category)
  • bool $formatted = false (default: false, whether to format the percentage)

getYuiProductTaxCategoryLabel​

Retrieves the tax category label for a product.

Parameters:

  • Product $product (the product to get the tax category label for)
