README

Template Resolver for Statamic is a simple utility addon, intended to be used by other addons. It provides a simple utility for selecting and rendering a template based on an entry's blueprint and collection, with support for a fallback default template.

Example use-cases:

• Selecting templates dynamically to generate social media images from HTML,
• Generating HTML documents on-the-fly, without requiring network requests to the site,
• Anything where you need to support customizable templates based on an entry's blueprint/collection details

How to Install

Run the following command from your project root:

composer require stillat/statamic-template-resolver

How to Use

You need to create an instance of StringTemplateManager, and supply the directory to search for templates in.

<?php

use Stillat\StatamicTemplateResolver\StringTemplateManager;

$manager = new StringTemplateManager(
    resource_path('views/social_media_images')
);

Once you have a StringTemplateManager instance, you can check if a template exists for a given collection/blueprint combination:

<?php

// ...

if ($manager->hasTemplate($collection, $blueprint)) {
    // The template exists.
}

The hasTemplate method will return true if a specific template or the default template exists. To create a default template, create a file named _default.antlers.html or _default.blade.php at the root of the template folder.

In our example, the default template would need to be placed here:

views/social_media_images/_default.antlers.html

Specific collection/blueprint templates are stored within a nested directory structure using the following format:

<template_directory><collection_handle>/<blueprint_handle>.<extension>

For example, if we had a blog collection, with a post blueprint, we could create a specific template at the following location:

views/social_media_images/blog/post.antlers.html

This library supports the following extensions:

• .antlers.html: Renders the template using Statamic's Antlers templating engine
• .blade.php: Renders the template using Laravel's Blade templating engine

To render a template with data, we may use the render method:

<?php

// ...

$results = $manager->render(
    'colllection_handle',
    'blueprint_handle',
    $data
);

The render method will return null if a template could not be found; $data is provided as an array, and is required.

We may also optionally modify the template before rendering it by supplying an optional callable as the fourth argument:

<?php

// Modify the template before its rendered.
$results = $manager->render(
    'collection_handle',
    'blueprint_handle',
    $data,
    function ($template, $data) {
        return mb_strtoupper($template);
    }
);

The modifying callable will receive the unmodified template contents as its first argument, and the original data array as the second.
