I have code:
{% set pageTitle = siteUrl('/search?keyword=' ~ query %}
return test test1
{% set pageTitle = siteUrl('/search?keyword=' ~ query|url_encode) %}
return test%20test1
{% set pageTitle = siteUrl('/search?keyword=' ~ query|url_encode(true)) %}
return test%20test1
How I can return test+test1 ?
Thank you.
Try replace filter (Twig replace documentation).
{% set pageTitle = siteUrl('/search?keyword=' ~ query|url_encode|replace({'%20': '+'})) %}

I have the following variables in twig:( I can see them with kint)
data.po_user_setting.us_highlight_color1 = '#008080'
data.po_user_setting.us_highlight_color2 = '#00FFFF'
data.po_user_setting.us_highlight_color3 = '#FFFF00'
data.po_user_setting.us_highlight_color4 = '#FF0000'
data.po_user_setting.us_highlight_color5 = '#FF00FF'
and
verse.po_verse_highlight.hl_rating = Returns [1-5]
How can I show the dynamic variable like this? Neither of these lines work:
{{_context['data.po_user_setting.us_highlight_color' ~ verse.po_verse_highlight.hl_rating]}}
{{attribute(_context, 'data.po_user_setting.us_highlight_color' ~ verse.po_verse_highlight.hl_rating)}}
The problem you are facing is the variable you want to access is actually an array.
With your current code, twig is looking for a variable called e.g., data.po_user_setting.us_highlight_color.foo, translated to $_context['data.po_user_setting.us_highlight_color.foo']
To actually access the variable you want, you would need to treat the variable like an array:
{{ {{ _context['data']['po_user_setting']['us_highlight_color'~ verse.po_verse_highlight.hl_rating] }} }}
This is quite long to type every time, so to reduce the typing you could use a macro or extend twig
macro
{% macro get_array_value(context, key) %}
{% set value = null %}
{% for key in key|split('.') %}
{% set value = loop.first ? context[key]|default : value[key]|default %}
{% endfor %}
{{ value }}
{% endmacro %}
As macro's don't have access to the special variable _context you would to pass this every time when you want to call the macro, e.g.
{% import _self as macros %}
{{ macros.get_array_value(_context, 'data.po_user_setting.us_highlight_color' ~ verse.po_verse_highlight.hl_rating) }}
extending twig
<?php
$twig->addFunction(new \Twig\TwigFunction('get_array_value', function ($context, $variable) {
$keys = explode('.', $variable);
if (empty($keys)) return;
$value = $context[array_shift($keys)] ?? [];
foreach($keys as $key) {
$value = $value[$key] ?? [];
}
return !empty($value) ? $value : null;
}, ['needs_context' => true,]));
Then you can call this function like the following in twig
{{ get_array_value('data.po_user_setting.us_highlight_color' ~ verse.po_verse_highlight.hl_rating) }}
In Craft CMS I want to search for the search query value for only some fields/ multiple fields - but not all.
For example limiting to the fields title, introduction, cardContent.
I've added a search: property to to my queryEntry object with the value of title and the query string. But I would like to add more fields.
{% set searchQuery = craft.app.request.getParam('q') %}
{# {% set queryEntries = craft.entries({
section: queryFilters
}).search(searchQuery) %} #}
{% set queryEntries = craft.entries({
search: 'title:' ~ searchQuery,
order: 'score'
}) %}
{% if craft.app.request.getParam('q') %}
{% set searchQuery = '"' ~ craft.app.request.getParam('q') ~ '"' %}
{% set queryEntries = craft.entries({
search: 'title:' ~ searchQuery ~ ' OR cardContent:' ~ searchQuery ~ ' OR introduction:' ~ searchQuery ,
order: 'score'
}) %}
{% endif %}
Get the query string
add searchTerms is concatinated in a string using OR and the query
This returns the array of entries matching the queryEntries.search and you can do what you like with this - eg loop over and display results
You can concatenate any number of fields with their value in the variable and then you can simple pass that in the search parameter with entries query. Here is the example code for that.
{% set nameparam = craft.app.request.getParam('data') %}
{% set categoryparam = craft.app.request.getParam('data1') %}
{% set queryString = '' %}
{% if nameparam is defined and nameparam is not empty %}
{% set queryString = queryString ~ 'title:*'~nameparam~'* ' %}
{% endif %}
{% if categoryparam is defined and categoryparam is not empty %}
{% set queryString = queryString ~ 'blogCategory:'~categoryparam~' ' %}
{% endif %}
{% if queryString is defined and queryString is not empty %}
{% set queryParams = {
search: {
query: queryString,
order: 'score'
},
} %}
{% else %}
{% set queryParams = {} %}
{% endif %}
{% set queryEntries = craft.entries(queryParams) %}
One question please.
{{ dump(app.user.slugName) }}
If I do the above snippet in Twig, I get the slugName of the user loged ("my-user-2", i.e.) in the app (SlugName is an atribute of the entity user). Ok & Correct. But... I want to order this action from a var (var from BD data)
I have a variable named option which is set like this:
{% set option = 'app.user.slugName' %}
But when I'm trying output this variable with {{ dump(option)}} it returns app.user.slugName as literal. It does not return my-user-2.
Is there are any way in twig to solve this? It's a function to generate a menu, but some links needs some parameters.
I see what you mean, but Twig can't evaluate expression like that.
To achieve something like that you would need a snippet like this,
{% set value_methods = 'app.user.slugname' %}
{% set option_value = _context %}
{% for method in (value_methods|split('.')) if method != '' %}
{% set option_value = attribute(option_value, (method|replace({'()': '', }))) %}
{% endfor %}
{{ option_value }}
twigfiddle
(edit)
Remember you can create a macro to achieve some reusability for this snippet,
{% import _self as macros %}
{{ macros.evaluate(_context, 'app.user.slugname') }}
{% macro evaluate(context, value_methods) %}
{% set option_value = context %}
{% for method in (value_methods|split('.')) if method != '' %}
{% set option_value = attribute(option_value, (method|replace({'()': '', }))) %}
{% endfor %}
{{ option_value }}
{% endmacro %}
This code gives error in twig.
{{ url( '/?page=signin'
{% if sidebar %} ~ '&sidebar=' ~ {{ sidebar }}{% endif %}
{% if post %} ~ '&post=' ~ {{ post }}{% endif %}
{% if next or page %} ~ '&next=' ~ {{ next ?: page }} {% endif %} ) }}
What would be the better way to do this type of concatenation?
This would work, but it require that each var (sidebar, post…) to be defined. It should contain value, or be false (or null). Ampersands are escaped automatically. If you'll use &sidebar it will be double-escaped (&).
{{ '/?page=signin' ~ (sidebar ? '&sidebar=' ~ sidebar) ~ (post ? '&post=' ~ post) }}
Is it possible to check if given variable is string in Twig ?
Expected solution:
messages.en.yml:
hello:
stranger: Hello stranger !
known: Hello %name% !
Twig template:
{% set title='hello.stranger' %}
{% set title=['hello.known',{'%name%' : 'hsz'}] %}
{% if title is string %}
{{ title|trans }}
{% else %}
{{ title[0]|trans(title[1]) }}
{% endif %}
Is it possible to do it this way ? Or maybe you have better solution ?
Can be done with the test iterable, added in twig1.7, as Wouter J stated in the comment :
{# evaluates to true if the users variable is iterable #}
{% if users is iterable %}
{% for user in users %}
Hello {{ user }}!
{% endfor %}
{% else %}
{# users is probably a string #}
Hello {{ users }}!
{% endif %}
Reference : iterable
Ok, I did it with:
{% if title[0] is not defined %}
{{ title|trans }}
{% else %}
{{ title[0]|trans(title[1]) }}
{% endif %}
Ugly, but works.
I found iterable to not be good enough since other objects can also be iterable, and are clearly different than an array.
Therefore adding a new Twig_SimpleTest to check if an item is_array is much more explicit. You can add this to your app configuration / after twig is bootstrapped.
$isArray= new Twig_SimpleTest('array', function ($value) {
return is_array($value);
});
$twig->addTest($isArray);
Usage becomes very clean:
{% if value is array %}
<!-- handle array -->
{% else %}
<!-- handle non-array -->
{% endif % }
There is no way to check it correctly using code from the box.
It's better to create custom TwigExtension and add custom check (or use code from OptionResolver).
So, as the result, for Twig 3, it will be smth like this
class CoreExtension extends AbstractExtension
{
public function getTests(): array
{
return [
new TwigTest('instanceof', [$this, 'instanceof']),
];
}
public function instanceof($value, string $type): bool
{
return ('null' === $type && null === $value)
|| (\function_exists($func = 'is_'.$type) && $func($value))
|| $value instanceof $type;
}
}
Assuming you know for a fact that a value is always either a string or an array:
{% if value is iterable and value is not string %}
...
{% else %}
...
{% endif %}
This worked good enough for me in a project I was working on. I realize you may need another solution.
