Keep leading 0 in Twig - symfony

In my database, I have a field containing the following data : 000010 (the type is integer)
In my twig tpl, I want to display it, then I do : {{ spending.documentName }}
But the browser displays "10". As if Twig was automaticcaly performing a trim on my data.
I tried {{ spending.documentName|raw }} but it doesn't work. I dont find anything on Google about how to keep leading 0 with Twig.
Does anyone know how to proceed ?

I think you must force the format (as your type is integer).
You can use the format filter :
{{ "%06d"|format(spending.documentName) }}
Or better create a twig extension (http://symfony.com/doc/current/cookbook/templating/twig_extension.html):
public function strpad($number, $pad_length, $pad_string) {
return str_pad($number, $pad_length, $pad_string, STR_PAD_LEFT);
}
It's clearer in your template :
{{ spending.documentName | strpad(6,'0') }}

You need to use the format filter.
Since placeholders follows the sprintf() notation, you should be able to convert sprintf('%06d', $integer); in PHP to {{ '%06d'|format($integer) }} in Twig.

Kinda late here, but ran into the same.
With twig 3.x you can use:
{{your.number | format_number({min_integer_digit:'2'})}}

translation strings in twig inside an object

I'm trying to put translation strings inside an object within Twig. So far I haven't got it right and can't figure out how to properly do it. I didn't think this would work, but it was my best effort so far.
{% set options = {
0 : {{ 'user.first_name'|trans }},
1 : {{ 'user.surname'|trans }},
2 : {{ 'user.initials'|trans }}
} %}
I get the error:
A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses (unexpected token "punctuation" of value "{".
Any one any ideas? Thanks in advance.
The syntax {{ ... }} is used to output content. You don't need to interpolate the variable in order to add it to the object
{% set options = {
0 : user.first_name|trans,
1 : user.surname|trans,
2 : user.initials|trans,
} %}
Some extra notes. As you are using numeric indices you could use the following snippet
{% set options = [
user.first_name|trans,
user.surname|trans,
user.initials|trans,
] %}

Translate the value of twig variable

Is it possible to translate the value of twig variables in a template with the 'trans' tag?
Say for instance I am passing a product to my template. This product has a definition with a trans tag e.g {{ product.definition|trans }}. This definition could either be in EN or DE or some other language. How could I translate the definition.
What are you trying to do is not a good way, It would look like this:
messages.en.yml
product:
definition:
some_value1: Some value 1
some_value2: Some value 2
and in template, you would do something like this:
{% set definition_value = product.definition %}
{% set trans_definition = 'product.definition.' ~ definition_value %}
{{ trans_definition|trans }}
it'll work, if it finds the key. What if it cant find it?
That's why you should use DoctrineBehaviors from KnpLabs, which handles all the dynamic translations for you..
If {{ product.definition }} equals 'cellphone' the following should work.
message.language.yml:
'cellphone': This will work!
However if you want to map it with the 'product' key in your message file like this:
product:
'cellphone': This also works
add the key to the twig template like so:
{{('product.'~product.definition)|trans }}

Passing all parameters as array and changing one of them

I am passing an array of get arguments from controller to twig template, and then create a link:
{{ url('route_name', array_of_get_parameters) }}
It works, but what if I want to pass all BUT ONE of those parameters unchanged? Something like:
{{ url('route_name', array_of_get_parameters, {'param1': 'value'}) }}
The example above doesn't work of course...is there a way to do this?
Use twig merge filter like this:
{{ url('route_name', array_of_get_parameters|merge({'param1': 'value'})) }}
You cannot do this.
Instead override the value in the controller (<- better) or in the twig template, before the url generation.

Pass variables to Twig Translator

In messages.en.yml:
variable_name: Welcome to %site_name% - %other_info%
In Twig
{{ 'variable_name'|trans( -here- ) }}
It's the -here- part I'm struggling to know how to pass data in. I must do it this way (above is just an example).
Maybe I'm misunderstanding the question but if I understand correctly, you only need to give an array as the first parameter of the trans filter.
{{ 'variable_name'|trans({'%site_name%': 'My Website'}) }}
And of course, values can be variables if you don't put them between quotes :
{{ 'variable_name'|trans({'%site_name%': 'My Website', '%other_info%': page_name}) }}

Symfony2 : Auto htmlentities using Twig

I'm displaying some variable retrieved in my database using Twig :
<p>{{ my_variable }}</p>
The thing is this variable may contain html tags, such as "<br />".
Twig seems to automatically call some htmlentities-like function when displaying variables.
Is there any way to disable it so that when I display a variable containing "Hello<br />world !" I get :
Hello
world !
rather than :
Hello<br />world !
Thanks
Use {{ my_variable|raw }} to prevent my_variable from being automatically escaped.
See Twig documentation: http://twig.sensiolabs.org/doc/filters/raw.html
Try using this
{% autoescape false %}{{ my_variable}}{% endautoescape %}
even better: {{ '<br />|raw('html') }} to avoid unescaping other sensible stuff.
If you just want to use linebreaks in the text stored in your database but don't care to use html , you can also use the nl2br filter as in {{ var|nl2br }}. Allows you to use string linebreak character \n in your text. Filter converts it to <br/>
