I have Twig variables:
{{ totalAmountMonth0 }} ... {{ totalAmountMonth10 }}
I have a loop and I want to call this variable for example:
{{ totalAmountMonth5 }}
I want to give this variable to a function like this:
totalAmount.percentFromTotalAmount((totalAmountMonth5))
But this doesn't work:
{% for i in 0..10 %}
{{ totalAmount.percentFromTotalAmount(totalAmountMonth~i) }}
{% endfor %}
This doesn't work either:
{% for i in 0..10 %}
{{ totalAmount.percentFromTotalAmount('totalAmountMonth'~i) }}
{% endfor %}
Untested, but try this:
{% for i in 0..10 %}
{{ totalAmount.percentFromTotalAmount(attribute(_context, 'totalAmountMonth'~i)) }}
{% endfor %}
Just provide to your twig an array, which I suggest, or build it (see below example)
// use line below only if array isn't provided to twig
{% set totalAmounts = { totalAmount1, totalAmount2, ..., totalAmount10 } %} // pseudo-code; you need to declare all variables here
{% for ta in totalAmounts %}
{{ totalAmount.percentFromTotalAmount(ta) }}
{% endfor %}
Try to set that variable before and use it.
{% for i in 0..10 %}
{% set temp = 'totalAmountMonth'~i %}
{{ totalAmount.percentFromTotalAmount(temp) }}
{% endfor %}

Since I'm using a SaaS platform I don't have much space to do things differently.
I have two for loops in Twig:
{% for option in product.options %}
{{ option.title }}
{% if option.values %}
{% for value in option.values %}
{{ value.title }}
{% endfor %}
{% endif %}
{% endfor %}
{% for variant in product.variants %}
{{ variant.stock.level }}
{% endfor %}
What I try to do is to use variant.stock.level value inside the product.options for loop to show some HTML. This value always match the corresponding index value of the other for loop. I also think that's the only way to do this.
So what I mean is.....Let's say both for loops contain 3 elements.
Option1
Option2
Option3
Variant1
Variant2
Variant3
So option1 needs to have the value from variant1.
For the end result I need to know what the value of eg Variant1 is to show some HTML like so:
{% for value in option.values %}
{% check if value from corresponding variant is greater then 0 %}
<li class="on-stock">{{ value.title }}</li>
{% else %}
<li class="out-of-stock">{{ value.title }}</li>
{% endif %}
{% endfor %}
I don't know no other way to explain this :) Any help appreciated....
You are looking for attribute.
The attribute function can be used to access a "dynamic" attribute of a variable
Since the indexes are the same, you can use loop.index0
Example for your case
{% if attribute(option.variants, loop.index0) > 0 %}
// some stuff
{% endif %}
I'm not sure if I understood you correctly but you may use key from first loop to access product.variants with the same index.
{% for key, option in product.options %}
{{ option.title }}
{% if option.values %}
{% for value in option.values %}
{{ value.title }}
{% endfor %}
{% endif %}
{{ product.variants[key].stock.level }}
{% endfor %}
So I have Twig running on top of Symfony 2.7. In the output html I'd like to have a few modules of text and in the last module I want some summary from all the previous ones (some data from all the previous modules' Entities) and I figured I'd append these summaries to a global variable while generating modules themselves to avoid a second loop. The code I'm using:
{% extends 'base.html.twig' %}
{% set list = '' %} {# HERE I SET A GLOBAL VAR #}
{% block body %}
<section>
<h2>{% trans %}MODULES{% endtrans %}</h2>
{% for m in plan.Modules %}
{{- block('module') -}}
{{ list }} {# HERE JUST FOR TESTING - IT'S EMPTY #}
{% endfor %}
</section>
{{ list }} {# HERE I WANT IT DISPLAYED, YET IT'S EMPTY :( #}
{% endblock %}
{% block module %}
<h3>{{ m.Module.title }}</h3>
{# HERE SOME MODULE TEXT I GET FROM COMPLICATED RELATIONS #}
{% if m.Module.list %}
{% set temp %}
{{ m.Module.shortTitle }}<br/>
{% endset %}
{% set list = list~temp %}
{% for l in m.Module.list %}
{% set temp %}
{{ l }}
{% endset %}
{% set list = list~temp %}
{% endif %}
{% endfor %}
{% endif %}
{{ list }} {# HERE IT'S WORKING #}
{% endblock %}
Any ideas?
First of all I'm learning Twig.
I was wondering if it is possible wit Twig to compare two different values from different arrays/lists?!
I have two list of items I call them like so:
{% if page.cart %}
{% for product in page.cart.products %}
{{ product.id }}
{% endfor %}
{% endif %}
And:
{% if products %}
{% for product in products %}
{{ product.id }}
{% endfor %}
{% endif %}
I want to compare both product.id's so I can create a new statement. Is there any way to compare both values? The idea is to check if an id is present in page.cart.products and if so then do something.
I want to create a new statement to display some info. Something like so:
{% if page.cart %}
{% for product in page.cart.products %}
{% set cartId %}{{ product.id }}{% endset %}
{% endfor %}
{% endif %}
{% if products %}
{% for product in products %}
{% set listId %}{{ product.id }}{% endset %}
{% endfor %}
{% endif %}
{% if cartId == listId %}
.... do this ....
{% endif %}
Any help greatly appreciated!
You can loop over one array and check if the id is present in the second one. If it's there, you can do something.
{# In case you want to store them, you can do so in an array #}
{% set repeatedIds = [] %}
{% for productCart in page.cart.products if page.cart %}
{% for product in products if products %}
{% if productCart.id == product.id %}
<p>This id -> {{ product.id }} is already in page.cart.products</p>
{% set repeatedIds = repeatedIds|merge([product.id]) %}
{% endif %}
{% endfor %}
{% endfor %}
{{ dump(repeatedIds) }}
It's a very basic search algorithm and the cost is quadratic. Obviously, there are more efficient ways to look for an element in an array (though more complicated to implement).
If the amount of products you have to deal with is not very big, you could use this solution. However, if you have, let's say, more than one hundred products in each array (or you feel that the algorithm is slowing down your loading time), you could do this process in the controller using more sophisticated methods and PHP and just pass the result to the template.
Hope it helps.
I have this Include
main.html.twig
{% set vars ={'id': user.id,'order': 'true'} %}
{% include "BDMOrderBundle::OrderForm.html.twig" with vars %}
OrderForm.html.twig
{{ form_start(form, {'action': path('myaction',{'id': post.id,'order':order})}) }}
Can I change the id and order in OrderForm.html.twig with
{{ form_start(form, {'action': path('myaction',vars)}) }}
try
{% include "BDMOrderBundle::OrderForm.html.twig" with {'vars': vars} %}
when you do
{% include "BDMOrderBundle::OrderForm.html.twig" with vars %}
its the same as
{% include "BDMOrderBundle::OrderForm.html.twig" with {'id': user.id,'order': 'true'} %}
so what is really passed to the BDMOrderBundle::OrderForm.html.twig is an array, not 'vars' variable
I'd like to create a custom template in twig to render a form field.
Example:
{{ form_row(form.field) }}
This can be overriden by form theming
{% block form_row %}
... custom code
{% endblock form_row %}
What I would like to do is this:
{% block custom_row %}
... custom code
{% endblock custom_row %}
and use it like this:
{{ custom_row(form.field }}
however, this throws an exception that method custom_row is not found.
My understanding is that this can be done with Twig extension, but I don't know how to register a block to be a function.
Update
what I actually want:
I use twitter bootstrap and a bundle which overrides all the form themes. And it renders a div around a radio, so it can't be inlined. So I wanted to do something like this:
copy their template and get rid of the div:
{% block inline_radio_row %}
{% spaceless %}
{% set col_size = col_size|default(bootstrap_get_col_size()) %}
{% if attr.label_col is defined and attr.label_col is not empty %}
{% set label_col = attr.label_col %}
{% endif %}
{% if attr.widget_col is defined and attr.widget_col is not empty %}
{% set widget_col = attr.widget_col %}
{% endif %}
{% if attr.col_size is defined and attr.col_size is not empty %}
{% set col_size = attr.col_size %}
{% endif %}
{% if label is not sameas(false) %}
{% if not compound %}
{% set label_attr = label_attr|merge({'for': id}) %}
{% endif %}
{% if required %}
{% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' required')|trim}) %}
{% endif %}
{% if label is empty %}
{% set label = name|humanize %}
{% endif %}
{% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' radio-inline')|trim}) %}
<label{% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>
{{ block('radio_widget') }}
{{ label|trans({}, translation_domain) }}
</label>
{% else %}
{{ block('radio_widget') }}
{% endif %}
{{ form_errors(form) }}
{% endspaceless %}
{% endblock inline_radio_row %}
and then
{{ inline_radio_row(form.field) }}
I ended up just overriding the whole theme, and added ifs around the div in question, a the class (radio-inline). But I'm still wondering if there's a way to make this work. Seems like it makes you work so hard for something so simple.
Update 2
I found the functionality:
class FormExtension extends \Twig_Extension
{
public function getFunctions()
{
return array(
'inline_radio_row' => new \Twig_Function_Node(
'Symfony\Bridge\Twig\Node\SearchAndRenderBlockNode',
array('is_safe' => array('html'))
),
);
}
}
This does exactly what I want, but it says it's deprecated. Anyone knows an updated version of how to use this?
Update 3
Similar functionality can be also achieved with http://twig.sensiolabs.org/doc/tags/include.html
You can use the twig functions for each part of a form row:
form_label(form.field)
form_widget(form.field)
form_errors(form.field)
For example:
<div class="form_row">
{{ form_label(form.field) }} {# the name of the field #}
{{ form_errors(form.field) }} {# the field #}
{{ form_widget(form.field) }} {# the errors associated to the field #}
</div>
You can use form theming.
Step by step:
1. Form Type Class
Check the name in your class
public function getName() {
return 'hrQuestionResponse';
}
2. Include a custom theme in your template
{% form_theme form 'InterlatedCamsBundle:Form:fields.html.twig' %}
3. Find the block
Can be quite difficult. For the bootstrap bundle, as you seem to have found it is in ./vendor/braincrafted/bootstrap-bundle/Braincrafted/Bundle/BootstrapBundle/Resources/views/Form/bootstrap.html.twig and you have found the block radio_row. I have been finding the block by putting output in the source template and overriding more blocks than I need. In 2.7 there is a theme 'rendering call graph'.
4. Override the block
Copy the block from the master template and call it replace the standard term with the name of in the FormType found in step 1.
Don't forget to also change the endblock name.
e.g.
{% block hrQuestionResponse_widget %}
hrQuestionResponse_row
{% spaceless %}
{% set class = '' %}
...
{% endspaceless %}
{% endblock hrQuestionResponse_widget %}
In your case because you can only call form_widget() you will need to override _widget. You could extract only the content that you need, or you can override the block chain to radio_row.
