Syntax
Twig defines three kinds of delimiters:
*
, to print the content of variables or the result of evaluating an expression (e.g.: an inherited Twig template with
).
*
, to add comments in the templates. These comments aren't included in the rendered page.
*
, to execute statements, such as for-loops.
**
, to assign.
**
... : condition.
**
... : counter in a loop.
The apostrophe (') is the escape character.
To create an iterative array:
An associative array:
Operators precedence
The operators precedence is,
from the less to more priority:
Filters
The filters provide some treatments on an expression, when placed after it, separated by pipes. For example:
*
capitalize: changes a string's first letter to capital.
*
upper: changes a whole string to capital.
*
first: displays the first line of an array.
*
length: returns a variable size.
Special variables
*
loop contains the current loop information. For example
loop.index corresponds to the number of iterations which have already occurred.
* The global variables begin with underscores. For example:
** _route (URL part located after the domain)
** _self (current file name)
*:So, to the a page route:
* The CGI
environment variables, such as
.
