I have a (very big) twig html template, where I display a table and loop through the rows:
{% for assignment in assignments %}
...
{% if assignment.zip.contractor1 is not null %}
{% for priceEK in assignment.zip.contractor1.pricecontractor %}
{% if priceEK.zip == assignment.zip %}
{% set bookDates = date(assignment.start|date).diff(assignment.end).days + 1 %}
{% set priceDay = 0 %}
{% set priceSide = 0 %}
{% if bookDates > 1 %}
{% set priceDay = priceEK.priceDay * (bookDates - 1) %}
{% set priceSide = priceEK.priceAdd * (bookDates) %}
{% endif %}
{% if assignment.meter == 15 %}
{{ (priceEK.price15 + priceDay + priceSide)|number_format(2) }}€
{% elseif assignment.meter == 20 %}
{{ (priceEK.price20 + priceDay + priceSide)|number_format(2) }}€
{% else %}
{{ (priceEK.price25 + priceDay + priceSide)|number_format(2) }}€
{% endif %}
{% endif %}
{% endfor %}
{%endif %}
Now this works like a charm IF, assignment.zip.contractor1 is not null is only true ONE TIME. If it is true a second time while looping through assignments it gives me the following error in my logs:
Error: Nesting level too deep - recursive dependency?
I assume this may be a complicated problem without knowing the database relations, please feel free letting me know what further info is needed (and how to insert here), I'll update accordingly.
//EDIT Maybe there is a way to 'reset' the nested for (priceEK)? {% set priceEK = null %} has no effect though...
//EDIT2: Found sth. else, changed all == to is same as() as described HERE. Now I can get a second loop. If I then have a third one, Firefox crashes and wants to debug the script...
//EDIT: ok, found a solution... Maybe this helps for someone else:
{% for pc in assignment.zip.pricecontractor %}
{% if pc.contractor is same as(assignment.zip.contractor1) %}
{% set bookDates = date(assignment.start|date).diff(assignment.end).days + 1 %}
{% set priceDay = 0 %}
{% set priceSide = 0 %}
{% if bookDates > 1 %}
{% set priceDay = pc.priceDay * (bookDates - 1) %}
{% set priceSide = pc.priceAdd * (bookDates) %}
{% endif %}
{% if assignment.meter is same as(15) %}
{{ (pc.price15 + priceDay + priceSide)|number_format(2) }}€
{% elseif assignment.meter is same as(20) %}
{{ (pc.price20 + priceDay + priceSide)|number_format(2) }}€
{% else %}
{{ (pc.price25 + priceDay + priceSide)|number_format(2) }}€
{% endif %}
{% endif %}
{% endfor %}

I am writing a unit test with Codeception to test a twig template. However, I am unable to find a way to mock the block.richTextFields.all() function. The block.richTextField is passed by the Twig context in this case so my initial thought was to create TwigFunction to mock it, but I can't find a way to have all function inside block.richTextField namespace.
{% for text in block.richTextFields.all() %}
{% if (loop.length < 3 and loop.length > 1 ) or (loop.length == 4) or (loop.length < 3 and loop.index == 2) or (loop.length < 6 and (loop.index == 4 or loop.index == 5)) %}
{% set topRowColWidth = "col-lg-6 margin-top-10" %}
{% elseif loop.length == 1 and loop.last %}
{% set topRowColWidth = "col-lg-12 margin-top-10" %}
{% else %}
{% set topRowColWidth = "col-lg-4" %}
{% endif %}
<div class="{{ topRowColWidth }} dynamic-rich-text">
{% if text.richTextField|length %}
{{text.richTextField}}
{% endif %}
</div>
{% endfor %}
My goal is having a string like "name: smoothie, ingredients: milk, orange, category: vegan" (there can be a lot option: value or option: value, value, value... pairs) to produce an array like the following
[
{
option: 'name',
value: ['smoothie']
},
{
option: 'ingredients',
value: ['milk', 'orange']
},
{
option: 'category',
value: ['vegan']
}
]
I thought something like the following would work but it produces the following error and i can't understand why.
The problem is in the line where i try to add a value to the existing options[last_ok_index].value array
{% set options[last_ok_index].value = options[last_ok_index].value|merge( [ x[0] ] ) %}
Unexpected token "punctuation" of value "[" ("end of statement block" expected).
{% set product = "name: smoothie, ingredients: milk, orange" %}
{% set options = [] %}
{% set last_ok_index = 0 %}
{% for item in product|split(',') %}
{% set x = item|split(': ') %}
{% if x|length == 2 %}
{% set options = options|merge( [ { option: x[0], value: [x[1]] } ] ) %}
{% set last_ok_index = loop.index - 1 %}
{% else %}
{% set options[last_ok_index].value = options[last_ok_index].value|merge( [ x[0] ] ) %}
{% endif%}
{% endfor %}
{# print result #}
{% for item in options %}
{{item.option }}
{% for inner_item in item.value %}
{{"-" ~ inner_item}}
{% endfor %}
{% endfor %}
You should go with the suggestion in the comments by #dbrumann and use a TwigExtension.
However if you want to solve this in pure twig, then you are overcomplicating things.
First things first, the problem already starts at your first split, your expected output is smoothie and ingredients, while the actual result will be smoothie, ingredients, orange. You can fix this by passiung asecond argument to the split filter, which will limit the output.
Split uses the PHP function explode in the background. More on what the second parameters does you can find in the documentation here
Now as I said you can simply your snippet by creating the "item" in two parts rather than one part
{% set product = "name: smoothie, ingredients: milk, orange" %}
{% set items = [] %}
{% for item in product|split(',', 2) %}
{% set tmp = item|split(':') %}
{% set option = tmp[0] %}
{% set values = [] %}
{% for value in tmp[1]|split(',') %}
{% set values = values|merge([ value, ]) %}
{% endfor %}
{% set items = items|merge([ {'option': option, 'values': values,}, ]) %}
{% endfor %}
demo
As you've changed the initial input of the original question. The problem still starts with the split filter. I'd suggest you use another delimeter for your values, e.g. ;
{% set product = 'name: smoothie 3, ingredients: milk ; orange; pineapple, category: bar' %}
{% set products = [] %}
{% for string in products_raw %}
{% set product = [] %}
{% for item in string|split(',') %}
{% set tmp = item|split(':') %}
{% set option = tmp[0] %}
{% set values = [] %}
{% for value in tmp[1]|split(';') %}
{% set values = values|merge([ value, ]) %}
{% endfor %}
{% set product = product|merge([ {'option': option, 'values': values,}, ]) %}
{% endfor %}
{% set products = products|merge([ product, ]) %}
{% endfor %}
{% for product in products %}
{% for item in product %}
- Option: {{ item.option }}
- Values:
{% for value in item.values %}
- {{value }}
{% endfor %}
{% endfor %}
----------------------------------
{% endfor %}
demo
Thank you a lot for all the tips, i changed the logic a bit and it works now.
I will search about twig extensions as you proposed since it is for sure too much code in twig for something like that.
{% set product = "name: smoothie, ingredients: milk, orange, sugar, tags: healthy, popular, category: milk" %}
{% set options = [] %}
{% set last_option = null %}
{% set last_value = null %}
{% for item in product|split(',') %}
{% set x = item|split(':') %}
{% if x|length == 2 %}
{% if last_value|length > 0 %}
{% set options = options|merge( [ {option: last_option, value: last_value} ] ) %}
{% endif %}
{% set last_option = x[0] %}
{% set last_value = [x[1]] %}
{% else %}
{% set last_value = last_value|merge([x[0]]) %}
{% endif%}
{% if loop.last %}
{% if last_value|length > 0 %}
{% set options = options|merge( [ {option: last_option, value: last_value} ] ) %}
{% endif %}
{% endif %}
{% endfor %}
{# print result #}
{% for item in options %}
{{ item.option }}
{% for inner_item in item.value %}
{{ "-" ~ inner_item }}
{% endfor %}
{% endfor %}
I am working on sidebar menu in a Custom Drupal 8 Theme. I am trying to set a class of sidebar__menu--submenu-1,sidebar__menu--submenu-2, sidebar__menu--submenu-3 and so on depending on the submenu's level.
So far, I was able to add the class sidebar__menu to the first level & sidebar__menu--submenu to all submenu's level. However, I want to add the 'class' sidebar__menu--submenu-(number of the level) so I can style & control the sidebar better with CSS.
Here it is my code menu.html.twig:
{{ menus.menu_links(items, attributes, 0) }}
{% macro menu_links(items, attributes, menu_level, menu_name) %}
{% import _self as menus %}
{%
set menu_classes = [
'sidebar__menu' ~ menu_name|clean_class,
]
%}
{%
set submenu_classes = [
'sidebar__menu' ~ menu_name|clean_class ~ '--submenu',
]
%}
{% if items %}
{% if menu_level == 0 %}
<ul{{ attributes.addClass('container mx-auto', menu_classes) }}>
{% else %}
<ul {{ attributes.removeClass(menu_classes).addClass(submenu_classes) }}>
{% endif %}
{% for item in items %}
{%
set classes = [
'sidebar__item',
item.is_expanded ? 'sidebar__item--expanded',
item.is_collapsed ? 'sidebar__item--collapsed',
item.in_active_trail ? 'sidebar__item--active-trail',
]
%}
<li{{ item.attributes.addClass(classes) }}>
{{ link(item.title, item.url) }}
{% if item.below %}
{{ menus.menu_links(item.below, attributes, menu_level + 1) }}
{% endif %}
</li>
{% endfor %}
</ul>
{% endif %}
{% endmacro %}
Any help will be really appreciate it!
I have found the answer. First we set the classes:
{%
set submenu_classes = [
'sidebar__menu' ~ menu_name|clean_class ~ '--submenu',
'sidebar__menu--submenu-' ~ (menu_level + 1),
]
%}
Then using the logic like so:
{% if menu_level == 0 %}
<ul{{ attributes.addClass('container mx-auto', menu_classes) }}>
{% else %}
<ul{{ attributes.removeClass(menu_classes, 'sidebar__menu--submenu-' ~ (menu_level)).addClass(submenu_classes) }}>
{% endif %}
We are making a website with a search form. In that form users can search with text and checkboxes. With the checkboxes users can search only in the related categories.
We need to accomplish this with Craft CMS and Twig.
We tried the following method, but that didnt worked.
{% set query = craft.request.getParam('search-results') %}
{% set nietBijdragePlichtig = craft.request.getParam('plg-Nee') %}
{% if nietBijdragePlichtig == 'on' %}
{% for entry in craft.entries.section('producten').limit(null).order(asc).search('query, nietBijdragePlichtig').find() %}
<div id=”test”>test</div>
{% endfor %}
{% endif %}
and we tried:
{% set query = craft.request.getParam('search-results') %}
{% set nietBijdragePlichtig = craft.request.getParam('plg-Nee') %}
{% set alle = query ~ ' ' ~ nietBijdragePlichtig %}
{% if nietBijdragePlichtig == 'on' %}
{% for entry in craft.entries.section(‘producten’).limit(null).order(asc).search(alle).find() %}
<div id=”test”>test</div>
{% endfor %}
{% endif %}
We also tried to use multiple .search()
We tried both codes with different syntaxes.
How can we accomplish this?
Really thanks!
I try to use a simple loop, in my real code this loop is more complex, and I need to break this iteration like:
{% for post in posts %}
{% if post.id == 10 %}
{# break #}
{% endif %}
<h2>{{ post.heading }}</h2>
{% endfor %}
How can I use behavior of break or continue of PHP control structures in Twig?
This can be nearly done by setting a new variable as a flag to break iterating:
{% set break = false %}
{% for post in posts if not break %}
<h2>{{ post.heading }}</h2>
{% if post.id == 10 %}
{% set break = true %}
{% endif %}
{% endfor %}
An uglier, but working example for continue:
{% set continue = false %}
{% for post in posts %}
{% if post.id == 10 %}
{% set continue = true %}
{% endif %}
{% if not continue %}
<h2>{{ post.heading }}</h2>
{% endif %}
{% if continue %}
{% set continue = false %}
{% endif %}
{% endfor %}
But there is no performance profit, only similar behaviour to the built-in break and continue statements like in flat PHP.
From docs TWIG 2.x docs:
Unlike in PHP, it's not possible to break or continue in a loop.
But still:
You can however filter the sequence during iteration which allows you to skip items.
Example 1 (for huge lists you can filter posts using slice, slice(start, length)):
{% for post in posts|slice(0,10) %}
<h2>{{ post.heading }}</h2>
{% endfor %}
Example 2 works TWIG 3.0 as well:
{% for post in posts if post.id < 10 %}
<h2>{{ post.heading }}</h2>
{% endfor %}
You can even use own TWIG filters for more complexed conditions, like:
{% for post in posts|onlySuperPosts %}
<h2>{{ post.heading }}</h2>
{% endfor %}
A way to be able to use {% break %} or {% continue %} is to write TokenParsers for them.
I did it for the {% break %} token in the code below. You can, without much modifications, do the same thing for the {% continue %}.
AppBundle\Twig\AppExtension.php:
namespace AppBundle\Twig;
class AppExtension extends \Twig_Extension
{
function getTokenParsers() {
return array(
new BreakToken(),
);
}
public function getName()
{
return 'app_extension';
}
}
AppBundle\Twig\BreakToken.php:
namespace AppBundle\Twig;
class BreakToken extends \Twig_TokenParser
{
public function parse(\Twig_Token $token)
{
$stream = $this->parser->getStream();
$stream->expect(\Twig_Token::BLOCK_END_TYPE);
// Trick to check if we are currently in a loop.
$currentForLoop = 0;
for ($i = 1; true; $i++) {
try {
// if we look before the beginning of the stream
// the stream will throw a \Twig_Error_Syntax
$token = $stream->look(-$i);
} catch (\Twig_Error_Syntax $e) {
break;
}
if ($token->test(\Twig_Token::NAME_TYPE, 'for')) {
$currentForLoop++;
} else if ($token->test(\Twig_Token::NAME_TYPE, 'endfor')) {
$currentForLoop--;
}
}
if ($currentForLoop < 1) {
throw new \Twig_Error_Syntax(
'Break tag is only allowed in \'for\' loops.',
$stream->getCurrent()->getLine(),
$stream->getSourceContext()->getName()
);
}
return new BreakNode();
}
public function getTag()
{
return 'break';
}
}
AppBundle\Twig\BreakNode.php:
namespace AppBundle\Twig;
class BreakNode extends \Twig_Node
{
public function compile(\Twig_Compiler $compiler)
{
$compiler
->write("break;\n")
;
}
}
Then you can simply use {% break %} to get out of loops like this:
{% for post in posts %}
{% if post.id == 10 %}
{% break %}
{% endif %}
<h2>{{ post.heading }}</h2>
{% endfor %}
To go even further, you may write token parsers for {% continue X %} and {% break X %} (where X is an integer >= 1) to get out/continue multiple loops like in PHP.
From #NHG comment — works perfectly
{% for post in posts|slice(0,10) %}
I have found a good work-around for continue (love the break sample above).
Here I do not want to list "agency". In PHP I'd "continue" but in twig, I came up with alternative:
{% for basename, perms in permsByBasenames %}
{% if basename == 'agency' %}
{# do nothing #}
{% else %}
<a class="scrollLink" onclick='scrollToSpot("#{{ basename }}")'>{{ basename }}</a>
{% endif %}
{% endfor %}
OR I simply skip it if it doesn't meet my criteria:
{% for tr in time_reports %}
{% if not tr.isApproved %}
.....
{% endif %}
{% endfor %}
