I'm trying to strip some text from a value and afterwards create an array from it with the stripped values.
I'm having troubles to strip the text value.
I can only do this on the frontend since I have no access to the backend (SaaS platform)
In below example value.value (originally a textarea) returns the following text:
[185047078]1x something - Type 1
[415533322]1x something - something
[152890667]1x something 500x500 mm
I want to strip the text so I have [185047078], [415533322], [152890667] left or without the brackets.
Normally in JS you would do something like:
hide_ids = txt.match(/[^\]\[]+(?=\])/g)
However it need to be done in Twig.
Afterwards I want to push the values into an array hide_ids.
{% set hide_ids = [] %}
{% if product.custom %}
{% for custom in product.custom %}
{% if 'Some title' in custom.title %}
{% for value in custom.values %}
{% set hide_this_id = value.value %}
{% if hide_this_id matches '{/[^\]\[]+(?=\])/g}' %}
{% set hide_ids = hide_ids | merge([hide_this_id]) %}
{% endif %}
{% endfor %}
{% endif %}
{% endfor %}
{% endif %}
{% set hidden = false %}
{% if id in hide_ids %}
{% set hidden = true %}
{% endif %}
What is the equivalent of match in Twig? I also tried replace but I just can't get that text stripped.
Any help greatly appreciated!
You could go with some simple string functions.
{% for id in ids %}
{{ id | split(']', 2)[0] | replace({'[': '',}) }}
{% endfor %}
demo
split is the explode of twig. This will separate your string in chased based on the ] character. The 2nd parameter (2) ensures there will only be maximum 2 parts in the array.
replace is just str_replace
If you wanted to solve this with regex you would either need to write a function/filter with preg_match or install an extension like this

I'm looping over a collection of blog posts (Twig for loop) which appearance depends on tags given.
Here a quick example: I want to display all blog posts that have the tags "foo" and "bar".
It seems pretty easy to check if a post has one of the tags.
However it seems that checking if both tags are contained by a blog post isn't trivial.
What I want to accomplish is what the array.every() method in javascript does.
That's my current solution which works as expected but feels kinda fiddly and overcomplicated:
{% set given_tags_array = data.tags|split(',') %}
{% for post in posts %}
{% set post_categories_array = post.categories|map(category => category.name) %}
{% set bool_buffer_array = [] %}
{# push comparison result in bool array #}
{% for tag in given_tags_array %}
{% set bool_buffer_array = bool_buffer_array|merge([tag in post_categories_array]) %}
{% endfor %}
{# only display posts where all tags match #}
{% if false in bool_buffer_array %}
{% else %}
{# post data goes here #}
{% endif %}
{% endfor %}
As you can see inside the posts loop I'm checking if every given tag (i.e. "foo" and "bar") is part of the post categories array. I'm pushing the comparison result (boolean) to an empty array to check for any false values afterwards.
Why an array? I tried using a simple boolean variable but if any of the given tags is in the post categories array it resolves to true, which isn't exactly what I want.
So something like that doesn't work for me unfortunately:
{% for post in posts %}
{% set post_categories_array = post.categories|map(category => category.name)|sort|join('') %}
{% if given_tags_array|filter(given_tag => given_tag in post_categories_array) %}
{# post data goes here #}
{% endif %}
{% endfor %}
With this method I'm always doing an or comparison instead of an and comparison...
So...am I missing something and is there a simpler way to do that twig only?
Using the code you've already provided:
{% set temp = given_tags_array|filter(given_tag => given_tag in post_categories_array) %}
The filter filter returns a new array, this means temp should contain as many elements as your given_tags_array, if they are all inside the post_categories_array.
So if I'm not mistaken you could change your check to the following
{% for post in posts %}
{% set post_categories_array = post.categories|map(category => category.name)|sort|join('') %}
{% set temp = given_tags_array|filter(given_tag => given_tag in post_categories_array) %}
{% if temp|length == given_tags_array|length %}
{# display post #}
{% endif %}
{% endfor %}
In a CraftCMs site I'm trying to loop through a couple categories, then loop through entries within each of those categories, but without duplicating the entry if it is in both categories.
Here's my base code:
{% set selectedCategories = craft.categories()
.id([12605, 12619])
.all()
%}
{% set articleAuthor = entry.id %}
{% for category in selectedCategories %}
{% set articles = craft.entries()
.section('articles')
.relatedTo([
'and', {articleAuthor}, {category}])
.all() %}
{% if articles %}
{% for article in articles %}
// entry data here
{% endfor %}
{% endif %}
{% endfor %}
This works, but if an entry is in both categories it shows in both sections. I want to limit it to showing in whatever may be the first listed section. What am I missing?
In this scenario you can create a variable and check whether a duplicate entry is found or not.
{% set existingIds = [] %}
{% for article in articles %}
{% if entry.id not in existingIds %}
{% set existingIds = existingIds|merge([entry.id]) %}
{% endif %}
{% endfor %}
I need to render a list of HTML elements with content and put it into a variable. How can I do this efficient in twig?
e.g. I need to render the post tracking URLs from an order which can have several shippings / parcels.
{% for delivery in order.deliveries %}
{% for trackingCode in delivery.getTrackingCodes() %}
{{ trackingCode }}<br/>
{% endfor %}
{% endfor %}
Instead of printing this directly into the output I like first to put this rendered output into a variable like
{% set output = ... %}
...
{{ output }}
How can I do this in twig?
Just the concatenate the html to the output variable. Keep in mind you'll need to define to the variable outside the for-loop in order to use it outside the loop.
{% set foo = '' %}
{% for i in 1..10 %}
{% set foo = foo ~ ''~i~'' %}
{% endfor %}
{{ foo|raw }}
demo
After long search I found a better more efficient way
you can use {% set var %} with {% endset %} as a whole output block. Means the whole output will be set to the variable. This makes the life much easier and readable.
e.g.
{% set trackingText %}
{% for delivery in order.deliveries %}
{% for trackingCode in delivery.getTrackingCodes() %}
{{ trackingCode }}<br/>
{% endfor %}
{% endfor %}
{% endset %}
...
{% if trackingText|trim is not empty %}
You can track the delivery by using the following URL:<br/>
{{ trackingText }}
<br/>
{% endif %}
I need to show a value from an element but his name is not always the same.
In my "competence" object, I have 4 fields, let's say field_1, field_2, field_3, field_4, but in function of an other value, I only have to display on of them.
I have the value in an other field of my "competence" object, "field_niveau_attendu" (it is set to 1, 2, 3 or 4)
I tried to use a "set" function
{% set niveau = "field_descriptif_" ~ competence.field_niveau_attendu.value %}
<p class="">{{ competence.field_competences_transverses.entity.niveau.value }}</p>
but it won't work
if in field_competences_transverses you have only 4 fields (field_1, field_2, field_3, field_4) you can try to use "for"
{% if competence.field_niveau_attendu.value is defined %}
{% set niveau = competence.field_niveau_attendu.value %}
{% for descriptif in competence.field_competences_transverses.entity %}
{% if loop.index == niveau %}
{{ descriptif.value }}
{% endif %}
{% endfor %}
{% endif %}
I want to replace part of string characters with asterisks in Twig.
For example:
SomePartlyVisibleStringHere
I want to change every letter after 4th in this string with asterisks, to have result like that:
Some*********************
Is it possible to do without defining new Twig helper?
You could make a macro (a function in Twig) and call it whenever you want to do this.
{% macro redact(topSecret) %}
{% set length = topSecret|length - 4 %}
{{ topSecret|slice(0, 3) }}{% for i in 0..length %}*{% endfor %}
{% endmacro %}
{# You have to import from _self if the macro is declared in the same file. #}
{% import _self as sharpie %}
{{ sharpie.redact('Top secret information') }}
{# => Top******************* #}
Example: https://twigfiddle.com/aobt8s
This worked for me:
{% set string = 'SomePartlyVisibleStringHere' %}
{% set starCount = string|length - 4 %}
{{ string[:4] }}{% for i in 1..starCount %}*{% endfor %}
If you have to do it more than once I would suggest making a custom filter, then you can just do:
{% set string = 'SomePartlyVisibleStringHere' %}
{{ string|customFilterName }}
