Twig Template Query

The Twig Template Data Source allows you to create reports in the Craft Control Panel using Twig Templates in your craft/templates folder.

Setting up a Custom Twig Template report requires a couple of steps.

1. Create a new Custom Twig Template Report
2. Add your Template Settings
3. Customize your Report's Results Template and Options Template settings

TIP

See the Sprout Reports in vendor/barrelstrength/sprout/templates/examples/datasets for commented example files of Twig Template Reports and Settings Templates. Copy those files to your craft/template folder and setup a Twig Template report to experiment with their usage or select them directly from a new Twig Template Query settings page by search for templates that begin with _sprout/examples/datasets/*.

Template Settings

To setup a Twig Template report you need to build a Results Template. Identifying your Results Template is the one required component of your Custom Twig Template report. The report template settings behave just like the Craft Sections 'Entry Template' setting.

• Results Template (required) - _reports/reportname/results
• Settings Template - _reports/reportname/settings

TIP

Sprout Reports will look for your templates in your front-end craft/templates folder so it's a good idea to use a hidden folder that can't be accessed directly from the web.

Results Template

Your Results Template is where you will build your report. A report consists of any number of rows. Rows must each have an equal number of columns.

The Twig Template Report has three helper tags to use when building reports:

Tag	Description
sprout.twigDataSet.addHeaderRow()	Define the columns in the first row of your report
sprout.twigDataSet.addRow()	Add a single row of data to your report
sprout.twigDataSet.addRows()	Add an array of multiple rows of data to your report

You can use addHeaderRow anywhere in your template to define the first row in your report that will be used as the column headers. The addRow and addRows actions add rows to your report in the order that they are used in your template.

The Twig Template Report also makes two variables available to your templates:

Variable	Description
settings	The values for all of your reports settings (e.g settings.mySetting)
isExport	The isExport variable will be set to true when your report is being processed as an export. One use for this is if you'd like to display a link in HTML in your report in the Control Panel, but want a text value when the report is exported.

Here is a simple, hard-coded example of each tag in use for a two-column report:

craft/templates/_reports/reportname/results.html

{# addHeaderRow accepts a single array with a comma-separated list of values #}
{% do sprout.twigDataSet.addHeaderRow(['Region', 'Trip Name']) %}

{# addRow, also accepts a single array with a comma-separated list of values. The array is defined by the opening and closing square brackets. #}
{% do sprout.twigDataSet.addRow([
  'Europe', 
  'Camino de Santiago'
]) %}

{# addRows, accepts an array of arrays, where each array includes a comma-separated list of values. Note that there are two levels of opening and closing square brackets. #}
{% do sprout.twigDataSet.addRows([
    ['North America', 'John Muir Trail'],
    ['Asia', 'Langtang Trek']
]) %}

Settings Template

If you want to give your user control over some Settings when they generate a Report, you can do so by defining an Settings Template.

TIP

Use the Form Macros supported by the Craft CP to keep consistent with the Craft UI. Sprout Reports will import the Craft CP Form Macros. Your Settings Template can look like this where the imported forms variable includes all Craft form macros defined in craft/app/templates/_includes/forms.html. :

craft/templates/_reports/reportname/settings.html

{# Number Setting #}
{{ forms.textField({
    label: "Limit"|t,
    name: "limit",
    size: 10,
    value: settings.quantity is defined ? settings.quantity : null,
    first: true
}) }}

{# Pre-defined Dropdown #}
{{ forms.selectField({
    label: "Region"|t,
    name: "region",
    options: {
        "africa" : "Africa",
        "antartica" : "Antartica",
        "asia" : "Asia",
        "australia" : "Australia",
        "europe" : "Europe",
        "northAmerica" : "North America",
        "southAmerica" : "South America"
    },
    value: settings.region is defined ? settings.region : "Antartica"
}) }}

{# Dynamic Dropdown #}
{% set categoryGroup = craft.categories.group('exampleCategoryGroup') %}
{% set categories = [] %}
{% for category in categoryGroup %}
    {% set categories = categories|merge({
        label: category.id,
        value: category.title
    }) %}
{% endfor %}

{{ forms.selectField({
    label: "Example Category Element Dropdown Field"|t,
    name: "exampleCategoryDropdownField",
    options: categories,
    value: 1
}) }}

All Settings are available to you via the settings variable. Be sure to test if they exist. See an example Settings Template with several common fields in the Sprout Reports examples/templates folder.

• Text
• Textarea
• Dropdown
• Radio Buttons
• Checkboxes
• Lightswitch
• DateTime (requires that you start the field name with "datetime", i.e. 'datetimeStartDate')

Examples also include how to toggle the display of conditional fields and how to use DateTime fields which require some additional steps. Additional field types can be used, but some fields with advanced validation may require that you create a Custom Data Source. The only field Twig Template Reports support with advanced validation requirements is the DateTime field.

Using Settings in Results

When a user runs a report, all Settings will be passed to the Results Template and can be used in your Settings Template Twig code to help query and display data how you wish:

reports/reportname/results.html

In this example we use our settings to retrieve a CategoryModel and then use that CategoryModel to retrieve all Trips that relate to that Category. We limit the results by the number provided by the user in the Limit setting.

{% set region = craft.categories.group(settings.region) %}
{% set trips = craft.entries.section('trips').relatedTo(region).limit(settings.limit) %}

{# Create a Header Row #}
{% do sprout.twigDataSet.addHeaderRow(['Region', 'Trip Name']) %}

{# Loop through our trips and output the Region and Trip Name for each result #}
{% for trip in trips %}
    {% do sprout.twigDataSet.addRow([
        trip.relatedCategory.first().title, 
        trip.title
    ]) %}
{% endfor %}
