I merged values of two arrays in a new array.
But I would like to take random values from this array and put them in a loop. That those values iterate in this loop.
{% set myArray = [] %}
{% set list1 = options.transitions_repeater %}
{% set list2 = options.transitions_wahou_repeater %}
{% set myArray = list1|merge(list2) %}
{% for key, val in myArray %}
{{ val|join(', ') }}
{% endfor %}
{% for item in options.projets %}
<li data-transisition="{{ myArray }}"></li>
{% endfor %}
I got the message : Array to string conversion in XX on line XX
Output :
animBottom
animTop
animLeft
directionRight
circles

Your merged list is still a multidimensional array.You could solve your issue with the following code, however it's preferable to move the logic of creating the (single dimensional) array to your controller (then you could remove the filter first in the snippet)
{% for item in options.projets %}
<li data-transisition="{{ myArray[random(myArray| keys)] | first }}"></li>
{% endfor %}

I want to use the loop.index variable in twig to get the corresponding alphabet letter (1 = A, 2 = B, etc).
{% for item in form.items %}
{% set nom_item = 'Item'~loop.index %}
{% endfor %}
How could I do to get alphabet letter in loop ? I can't find a twig function for that.
Simplest solution
{{ range('A','Z')[loop.index0] }}
try with this!
{% set foo = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'] %}
{% for index,item in form.items %}
{% set nom_item = 'Item'~foo[index] %}
{% endfor %}
The title is a bit ambiguous I know, but let me explain what I'm trying to achieve.
I am attempting to generate a CSV based on data pulled from a doctrine query in my Symfony2 CRM. The data retrieved is based on OpenCart Product and Attribute data, as well as some bespoke information which is irrelevant for this issue.
Each product can have up to 5 different attribute values, named A, B, D, L1 and L2. However, some products do not have all of them, only A, B and L1. The CSV requires each attribute value to be in a separate cell - so the headers are as follows:
ATTRIBUTE: A | ATTRIBUTE: B | ATTRIBUTE: D | ATTRIBUTE: L1 |
ATTRIBUTE: L2
And then I loop through in my Twig file as follows:
{% for attribute in row.product.attributes %}
{% if attribute.text is not null %}
{{ attribute.text }},
{% else %}na,{% endif %}
{% endfor %}
If the product has all 5 attributes, the structure of the CSV is fine. However, if the product only has 3 attributes, it means that all of the subsequent values are pulled back a cell, meaning that the other data is under the wrong headings. I tried checking for values first:
{% for attribute in row.product.attributes %}
{% if attribute.attributeName.name == "A" %}
{% if attribute.text is not null %}
{{ attribute.text }},
{% else %}na,{% endif %}
{% endif %}
{% endfor %}
And I did this for each possible attribute name, but unfortuantely this does not work since if the name does not exist, it just skips it anyway. I'm having trouble trying to think of a way to loop through these attributes and entering a n/a if it's non existent - I'm sure there is a way but I don't know what it is.
For reference, here is the controller code that's generating the data for the CSV:
public function adminCsvAction($filter) {
$repository = $this->getDoctrine()->getRepository('AppBundle:Project');
$stages_repository = $this->getDoctrine()->getRepository('AppBundle:Stage');
$users_repository = $this->getDoctrine()->getRepository('AppBundle:User');
$results = $repository->getSearchResults($filter);
$users = $users_repository->findAll();
$stages = $stages_repository->findBy(array('deleted' => 0), array('sortOrder' => 'ASC'));
$filename = "export_".date("Y_m_d_His").".csv";
$response = $this->render('AppBundle:pages:csv.html.twig', array('data' => $results,'users' => $users, 'stages' => $stages));
$response->headers->set('Content-Type', 'text/csv');
$response->headers->set('Content-Disposition', 'attachment; filename='.$filename);
return $response;
}
The Project Entity has various mappings, one of which links to the Product table in OpenCart which means all attributes and linked values are accessible via this.
Any help in this is much appreciated.
I also agree with Cerad from comment section - that is not the job for Twig. In case your really need to do it, I would try roughly something like this:
{% set allAttr = ["A","B","D","L1","L2"] %}
{% for attribute in allAttr %}
{% if row.product.attributes[attribute] is defined %}
{{ row.product.attributes[attribute].text }}
{% endif %}
{% if not loop.last %},{% endif %}
{% endfor %}
I guess the is defined is critical here...
OK I figured it out. Using what Jovan Perovic suggested, I came up with this:
{% set allAttr = ["A","B","D","L1","L2"] %}
{% set prodAtts = [] %}
{% for row in data %}
{% set existingAtts = [] %}
{% for att in allAttr %}
{% if att not in prodAtts %}
{% set prodAtts = prodAtts|merge([att]) %}
{% endif %}
{% endfor %}
{% for rowAtt in row.product.attributes %}
{% set existingAtts = existingAtts|merge({(rowAtt.attributeName.name|trim):(rowAtt.attributeName.name|trim~'_'~rowAtt.text|trim)}) %}
{% endfor %}
{% for prodAtt in prodAtts %}
{% if prodAtt not in existingAtts|keys %}
{% set existingAtts = existingAtts|merge({(prodAtt):(prodAtt~'_na')}) %}
{% endif %}
{% endfor %}
{% set orderedAtts = existingAtts|sort %}
....
Then the loop for each row thereafter. I used the attribute name with an underscore in order to be able to sort it correct (as it only sorts by value not key) then used preg_replace to remove it along with any instance of the name so I just ended up with the value.
Bit of a lengthy - and probably over thought - solution but it does work!
I have two loops in Twig. One is to check the stock level of a product, the other is to display some product options. I'm trying to create a variable from one loop which I can use inside the other to add a class name to a list(s).
I can't get that to work. Any help is more then welcome...
What I have is this:
{% set stockLevel = '' %}
{% for variant in product.variants %}
{% set stockLevel = variant.stock.level %}
{{ stockLevel }} // gives 1 0 1 1 (So all sizes except the second one are available)
{% endfor %}
{% for option in product.options %}
<ul class="optionslist">
{% if option.values %}
{% for value in option.values %}
<li class=" {% if stockLevel == 0 %}not_on_stock {% endif %}" >
<a class="item">etc...</a>
</li>
{% endfor %}
{% endif %}
</ul>
{% endfor %}
I believe there is something wrong the way you are handling your data. Right now, event if your variable was accessible in your second for loop, the value of it would be the one set lastly and your script would've failed anyway.
I can suggest a bit of a hacky way, feel free to improvise or use the idea behind it.
Say, we assign an empty array:
{% set variantsArray = [] %}
Then, we will use the filter merge to fill it with some dummy data(that's where your first loop comes into play)
{% for number in 1..5 %}
{% set variantsArray = variantsArray | merge([number]) %}
{% endfor %}
Then to be sure, we can access all the values there, we will just dump it out(that's where your second loop comes)
{% for index in 1..3 %}
{{ dump(variantsArray) }}
{% endfor %}
The following dump generated:
array:5 [▼
0 => 1
1 => 2
2 => 3
3 => 4
4 => 5
]
Hope you got the idea. Any suggestions are kindly welcome.
I am not sure what you are trying to do, how do you get your stock level from the variants? i think it is better to have a service function which help you get your stock level by product, the code would be cleaner :
controller action
$stock_helper = $this->container->get('stockhelper_service');
$stocklevel = $stock_helper->getStockLevelByProduct($product); //getstocklevelbyproduct handle your logic and return the stock level integer.
pass this variable to the twig.
One variable in your twig, no loops there, clean view, understandable code in your view and action.
Ok, I found the solution. The trick is to "connect" both values. Like so:
{% for option in product.options %}
{% if option.values %}
<ul id="product_configure_option2_{{ option.id }}" data-id="{{ option.id }}">
{% for value in option.values %}
{% set stock = null %}
{% for variant in product.variants **if variant.title == (option.title ~ ': ' ~ value.title)** %}
{% set stock = variant.stock %}
{% endfor %}
<li value="{{ value.id }}"{% if not stock.available %} class="not_on_stock"{% endif %}>{{ value.title }}</li>
{% endfor %}
</ul>
{% endif %}
{% endfor %}
Lets say I have some data called 'brands ' in an array past into a twig template like this:
{ 0:1,1:2,2:3,3:4,4:5,5:6,6:7,7:8}
Second array called 'designs' like this
{120:11,123:22,189:32,300:34,400:53,500:63,688:37,799:28}
o/p excepted
12,24,35,38,59,70,45,36
the below code shows what i have tried and the o/p expected for 8 times, but i am getting 64 times the output like
{% for key ,value in brands %}
{% for key,design in designs %}
// for example i need to add the value and design for 8 times
{% set total = value + design %}
{% endfor %}
{% endfor %}
You are incorrectly nesting your loops, and adding each element of designs to each element of brands. You only need one loop:
{% for key, value in brands %}
{% set total = value + designs[key] %}
{% endfor %}
Don't forget you can't access total unless you define it before starting the loop:
{% set total = 0 %}
{% for key, value in brands %}
{% set total = value + designs[key] %}
{% endfor %}
If you're looking for the sum of both of the arrays into one total with varying numbers of elements for brands and designs:
{% set total = 0 %}
{% for key, value in brands %}
{% set total = total + value %}
{% endfor %}
{% for key, value in designs %}
{% set total = total + value %}
{% endfor %}
If you're looking to add together each corresponding element between designs and brands without depending on matching keys - it's a much more difficult process when trying to do it in Twig, and you're missing what Twig is meant for entirely. You should handle this data in the controller or build a better data model to pass to Twig. For example:
$brands = array(0=>1,1=>2,2=>3,3=>4,4=>5,5=>6,6=>7,7=>8);
$designs = array(120=>11,123=>22,189=>32,300=>34,400=>53,500=>63,688=>37,799=>28);
$brands_designs = array();
foreach ($brands as $key => $brand) {
$design_key = key($designs);
$brands_designs[$key] = array(
'brand' => $brand,
'brand_key' => $key,
'design' => next($designs),
'design_key' => $design_key
);
}
return $this->render('AcmeBundle:Folder:template.html.twig', array('brands_designs' => $brands_designs));
Then in your Twig template:
{% for key, value in brands_designs %}
{% set total = value.brand + value.design %}
{% endfor %}
But if you insist on matching each element together and adding them individually...
{% for brandKey, brand in brands %}
{% set outerLoopIndex = loop.index %}
{% for designKey, design in designs %}
{% if outerLoopIndex == loop.index %}
{% set total = brand + design %}
{# do stuff with total here, like {{ total }} #}
{% endif %}
{% endfor %}
{% endfor %}
The above isn't tested, I'm a little worried about variable scope in there. It actually iterates a total of 64 times with your sample set but only outputs on the diagonal (when the outer index == inner index, so 1 == 1, 2 == 2, etc.)
how to retrieve the value (string) of an array's element and retrieve the property value of an entity? I tried this:
{% for item in items %} //item is an entity
{% for column in columns %} //column is just an array with name of columns
{% set columna = column.value %}
{{ item.columna }}
{% endfor %}
{% endfor %}
If you want to access dynamically a property of an object, you can use the attribute function :
{% for item in items %}
{% for column in columns %}
{{ attribute(item , column.value) }}
{% endfor %}
{% endfor %}
Try this:
{% for item in items %} //item is an entity
{% for column in columns %} //column is just an array with name of columns
{% set columna = column.value %}
{{ attribute(item, columna) }}
{% endfor %}
{% endfor %}
I recommend reading the documentation.
