i want to set dynamic variable and get value of that variable. I had pass "orderDetails" to my twig template.
$customerProfile = array(
'ns1' => $customerProfile->getNs1(),
'ns2' => $customerProfile->getNs2(),
'custId' => $customerProfile->getCustId()
)
return $this->render('PortalBundle::popup.html.twig', array(
'orderDetails' => $customerProfile
));
get that variable like {{orderDetails.ns1}}, {{orderDetails.ns2}} like this but i have 15 to 16 variable like this and i want to fetch this variable in loop.
i have code for this like
{% for i in 1..13 %}
{% set nsOrd = 'orderDetails.ns'~i %}
{% if nsOrd %}
{{nsOrd}}
{% endif %}
{% endfor %}
i want to fetch variable {{orderDetails.ns1}} and other. Give me your suggestion.
thanks Yoshi, I have hundered of variable in array. thanks for support, i have found and successfully get output using this.
{% for i in 1..13 %}
{% if orderDetails['ns' ~ i] is defined %}
{{orderDetails['ns' ~ i]}}
{% endif %}
{% endfor %}

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 %}
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'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 would like to do the following:
{% for i in 0..10 %}
{% if content_{{ i }}_raw == 2 %}
...
{% endif %}
{% endfor %}
Is it possible to get {{ i }} inside the variable content_1_raw and replace the 1 with the value of i?
Yes. The _context variable holds all variables in the current context. You can access its values with the bracket notation or using the attribute function:
{% for i in 0..10 %}
{% if _context['content_' ~ i ~ '_raw'] == 2 %}
...
{% endif %}
{# or #}
{% if attribute(_context, 'content_' ~ i ~ '_raw') == 2 %}
...
{% endif %}
{% endfor %}
I have written more details about this here: Symfony2 - How to access dynamic variable names in twig
Also, instead of writing 'content_' ~ i ~ '_raw' (tilde, ~, is string concatenation operator), you can also use string interpolation:
"content_#{i}_raw"
I want to reuse pretty heavy logic only code a few times, in php I would use a function, but in twig I went with a solution from this old question.
In short, I use a macro like that:
{% import _self as test %}
{% macro check() %}
{{ test }}
{% endmacro %}
{% set v = test.check() %}
{% if v == 'test' %}
this should display
{% endif %}
Here is a fiddle: https://twigfiddle.com/kyv3zr/2
The problem is that v is a Twig_markup object. It doesn't seem to have any public properties. Running dump on it gives me this:
object(Twig_Markup)#1244 (2) { ["content":protected]=> string(13) " 1 " ["charset":protected]=> string(5) "UTF-8" }
How do I use it in an if statement?
Or is there a better way of storing a logic only code for reuse across templates?
If the object is called v then the dump seems to show it has a content value, so try:
{% if v.content == '1' %}
{# do something here #}
{% endif %}
not certain though, but try it.
EDIT #2 - based on comments question.
So I guess if you want to use v in an if statement, you would use it like so:
{% if v == '1' %}
{# do something here #}
{% endif %}
This presumes it does equal to "1".
