I want to render blocks of HTML in alternate orientations. Is this the correct syntax in order to get the current value of cycle?
{% if ( {{ cycle(['odd', 'even']) }} == 'odd' ) %}
foo
{% elseif %}
bar
{% endif %}
cycle(['odd', 'even']) should not be inside {{ }} in the if
statement
cycle() should have a second parameter given that counts the amount of loops
the {% elseif %} should either have a condition or be changed to {% else %}
This is what you should do to get the code to work as you want it to (loop 10 times):
{% for i in 0..9 %}
{% if cycle(['odd', 'even'], i) == 'odd' %}
foo
{% else %}
bar
{% endif %}
{% endfor %}
If you want the for to loop objects you can use loop.index (starts at 1) instead of i:
{% for object in objects %}
{% if cycle(['even', 'odd'], loop.index) == 'odd' %}
foo
{% else %}
bar
{% endif %}
{% endfor %}
or loop.index0 (starts at 0):
{% for object in objects %}
{% if cycle(['odd', 'even'], loop.index0) == 'odd' %}
foo
{% else %}
bar
{% endif %}
{% endfor %}

I'm trying to use the "AND" operator in TWIG in Opencart 3 and it doesn't work. Please tell me what I'm doing wrong.
I have some product attributes. And I want to make a condition that if two of the attribute with a specific ID are there, then the condition is met.
{% for attribute_group in attribute_groups %}
{% for attribute in attribute_group.attribute %}
{% if attribute.attribute_id == 2 and attribute.attribute_id == 3 %}
First condition
{% elseif attribute.attribute_id == 2 %}
Second condition
{% elseif attribute.attribute_id == 3 %}
Third condition
{% else %}
{% endif %}
{% endfor %}
{% endfor %
Here is text example:
if there is an attribute with ID equal 2 and an attribute with ID equal 3 then write "Floor/Number of floors".
if there is an attribute with ID equal 2 only then write "Floor"
if there is an attribute with ID equal 3 only then write "Numbers of floors".
Something can't be both X and Y at the same time. Furthermore this is something I'd advice you to test in the controller and not in the view.
Anyway if you wanted to do this in the view you will need to track of the found attributes. You could do this with two booleans or just add a counter.
{% set cnt = 0 %}
{% for attribute_group in attribute_groups %}
{% for attribute in attribute_group.attribute %}
{% if attribute.attribute_id == 2 or attribute.attribute_id == 3 %}
{% set cnt = cnt + 1 %}
{% endif %}
{% endfor %}
{% endfor %}
{% if cnt == 2 %}
{# do something #}
{% endif %}
You can simplify the if by using the test in
{% if attribute.attribute_id in [2, 3,] %}
Update of my answer because OP changed the requirements of the question
{% set words = [] %}
{% for attribute_group in attribute_groups %}
{% for attribute in attribute_group.attribute %}
{% if attribute.attribute_id == 2 %}
{% set words = words|merge(['Floor',]) %}
{% elseif attribute.attribute_id == 3 %}
{% set words = words|merge(['Numbers of floors',]) %}
{% endif %}
{% endfor %}
{% endfor %}
{% if words|default %}
{{ words|join('/') }}
{% endif %}

I need to pass some values into my twig file. The defaults should be:
{% set pos.top|default(0) %}
{% set pos.right |default(0) %}
{% set pos.bottom |default(0) %}
{% set pos.left |default(0) %}
If no new values are given I don't need to use those, however, if either of the four is not 0 I need to add inline style
{% if ...(top == 2)... %}
style="position: relative; top: 2px"
{% endif %}
How do I put it together?
Something like this should work.
{% set addInline = false %}
{% for key, value in pos %}
{% if value != 0 %}
{% set addInline = true %}
{% endif %}
{% endfor %}
{% if addInline %}
style="
position: relative;
{% for key, value in pos %}
{% if value != 0 %}
{{ key }}: {{ value }}px;
{% endif %}
{% endfor %}
"
{% endif %}
Below is my code. I want to increase J loop index in between inner loop so I have incremented J variable but it is not working.
`{% for j in 0..(products|length-1) %}
{% for f in 0..(rows-1) %}
{% set j = j + 1 %}
{% endfor %}
{% endfor %}`
Is there any other way to increase loop index?
Its not possible to alter the loop indeces of twig due to the fact of how the loops are compiled
{% for i in 1..5 %} for example gets compiled as
$context['_seq'] = twig_ensure_traversable(range(1, 5));
foreach ($context['_seq'] as $context["_key"] => $context["i"]) {
//..
}
I do have another aproach for you to solve this with twig
{% set rows = 2 %}
{% set items = ((products|length) / rows) | round %}
{% for product in products %}
{% if loop.index0 % items == 0 %}
<div class="row">
{% endif %}
<div class="product">
{{ product }}
</div>
{% if loop.index % items == 0 or loop.last %}
</div>
{% endif %}
{% endfor %}
I have the following twig code:
{% set button_class = button_class_off|default('toggle toggle-thumbs-down') %}
{% set button_toggle_swap = button_toggle_swap|default(['toggle-thumbs-down', 'toggle-thumbs-up']) %}
{% if value == '1' %}
{% dump(name) %}
{% for swap in button_toggle_swap %}
{% if swap in button_class %}
{% dump(swap) %}
{% dump(button_class) %}
{% set button_class = button_class|replace({swap: ""})|trim %}
{% dump(button_class) %}
{% else %}
{% set button_class = button_class ~ ' ' ~ swap %}
{% endif %}
{% endfor %}
{% endif %}
The dump shows:
"hifi"
"toggle-thumbs-down"
"toggle toggle-thumbs-down"
"toggle toggle-thumbs-down"
I have no idea why the replace does not work. I have tried this with and without the trim. The result is that the replace of swap with "" is ignored.
Any idea what I am doing wrong here?
OK. There appears to be some missing details in the documentation. If using a variable (not an absolute string) the the variable must be wrapped in parenthesis ().
This code works:
{% set button_class = button_class_off|default('toggle toggle-thumbs-down') %}
{% set button_toggle_swap = button_toggle_swap|default(['toggle-thumbs-down', 'toggle-thumbs-up']) %}
{% if value == '1' %}
{% for swap in button_toggle_swap %}
{% if swap in button_class %}
{% set button_class = button_class|replace({(swap): ""})|trim %}
{% else %}
{% set button_class = button_class ~ ' ' ~ swap %}
{% endif %}
{% endfor %}
{% endif %}
Thanks to this answer to str_replace in twig
How can i access the loop's index when i'm in a second loop? like this:
{% for i in range(0, 3) %}
{% for j in range(0, 9) %}
{{ loop1.index + loop2.index }} // ?
{% endfor %}
{% endfor %}
In fact there's no need to set an extra variable. For two nested loops twig provides the so called parent.loop context.
To access the parents loop.index do this:
{% for i in range(0, 3) %}
{% for j in range(0, 9) %}
{{ loop.parent.loop.index + loop.index }}
{% endfor %}
{% endfor %}
Also refer to the documentation
set a variable which hold the first loop.index
{% for i in range(0, 3) %}
{% set loop1 = loop.index %}
{% for j in range(0, 9) %}
{{ loop1 + loop.index }}
{% endfor %}
{% endfor %}
