twig.md

use a variable

	{% if getModVar('RKShowRoomModule', 'property01') == false %}
		...
	{% endif %}

better instead getModVar('RKShowRoomModule', 'property01') you use a default value getModVar('RKShowRoomModule', 'property01' default value). With the default value you are on the safe side if the variable do not exist or is empty.

Variables for field length

inside the corresponding edit.html.twig you may want to add the maxlength. e.g.

{{ form_row(form.descriptionTeaser, { 'attr': { 'maxlength': getModVar('RKShowRoomModule', 'storyTeaserDescriptionLength') }}) }}

override help text

If we want to override the help text with the allowed number of characters we can do as follow:

{% set allowedLength = getModVar('RKShowRoomModule', 'descriptionLength', 200) %}
{{ form_row(form.description, { 'attr': { 'maxlength':  allowedLength }, 'help' : __f('Allowed length is %amount% characters.', { '%amount%': allowedLength }) }) }}

the original help text is than not available anymore

check for permissions

	{% if hasPermission('RKShowRoomModule:ShowRoomItem:', '::', 'ACCESS_EDIT') %}
		...
	{% endif %}

truncate with a variable

	{% set truncateLength = getModVar('RKShowRoomModule', 'teaserTruncateStoryListlength', 123) %}
	{{ showRoomItem.descriptionTeaser|striptags|truncate(truncateLength) }}

use |striptags instead of |safeHtml to ensure you are not cutting html in a tag

string combination

{% set templateTitle = showRoomItem.title ~ ' ' ~ showRoomItem.property01 ~ ' ' ~ showRoomItem.property02 %}

in this example I create a new template title. The strings are combined via ~

Block in block

Du kannst Blöcke in anderen Blöcken aufrufen: {{ block('meinblock') }} Dabei werden die bestehenden Variablen übergeben.
