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 %}

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 %}
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 %}
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 am implementing an alphabetical search.
We display a table of Names. I want to highlight only those alphabets, which have names that begin with the corresponding alphabet.
I am stumped with a simple problem.
How to read the first character in the string user.name within twig.
I have tried several strategies, including the [0] operation but it throws an exception.
Here is the code
{% for i in ['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','0-9'] %}
{% set has_user_starting_with_alphabet = false %}
{% for user in pagination %}
{% if user.name[0]|lower == i %}
{% set has_user_starting_with_alphabet = true %}
{% endif %}
{% endfor %}
{% if has_user_starting_with_alphabet %}
<li><span>{{ i }}</span></li>
{% endif %}
{% endfor %}
Is there some function like "starts_with" in twig?
Since twig 1.12.2 you can use first:
{% if user.name|first|lower == i %}
For older version you can use slice:
{% if user.name|slice(0, 1)|lower == i %}
Note: You may also use this notation:
{% if user.name[:1]|lower == i %}
