This document describes the syntax and semantics of the template engine and will be most useful as reference to those creating Twig templates. A template is simply a text file. It doesn't have a specific extension. A template contains variables or expressionswhich get replaced with values when the template is evaluated, and tagswhich control the logic of the template.

Below is a minimal template that illustrates a few basics. We will cover further details later on:. There are two kinds of delimiters: The first one is used to execute statements such as for-loops, the latter prints the result of an expression to the template. Also, TwigFiddle is an online service that allows you to execute Twig templates from a browser; it supports all versions of Twig. The application passes variables to the templates for manipulation in the template.

Variables may have attributes or elements you can access, too. The visual representation of a variable depends heavily on langue binaire tableau de bord wordpress themes application providing it.

You can use a dot. When the attribute contains special characters like - that would be interpreted as the minus operatoruse the attribute function instead to access the variable attribute:. It's important to know that the curly braces are not part of the variable but the print statement. When accessing variables inside tags, don't put the braces around them. For convenience's sake foo.

If you want to access a dynamic attribute of a variable, use the attribute function instead. You can assign values to variables inside code blocks. Assignments use the set tag:. Variables can be modified by filters. Filters are separated from the variable by a pipe symbol and may have optional arguments in parentheses. Multiple filters can be chained.

The output langue binaire tableau de bord wordpress themes one filter is applied to the next. The following example removes all HTML tags from the name and title-cases it:.

Filters that accept arguments have parentheses around the arguments. This example will join a list by commas:. To apply a filter on a section of code, wrap it in the filter tag:. Go to langue binaire tableau de bord wordpress themes filters page to learn more about built-in filters. Functions can be called to generate content.

Functions are called by their name followed by parentheses and may have arguments. For instance, the range function returns a list containing an arithmetic progression of integers:. Go to the functions page to learn more about the built-in functions. Using named arguments makes your templates more explicit about the meaning of the values you pass as arguments:.

Named arguments also allow you to skip some arguments for which you don't want to change the default value:. You can also use both positional and named arguments in one call, in which case positional arguments must always come before named arguments:. Each function and filter documentation page has a section where the names of all arguments are listed when supported. A control structure refers to all those things that control the flow of a program - conditionals i. For example, to display a list of users provided in a variable called usersuse the for tag:.

The if tag can be used to test an expression:. Go to the tags page to learn more about the built-in tags. This is useful for debugging or to add information for other template designers or yourself:. The include function is useful to include a template and return the rendered content of that template into the current one:.

By default, included templates langue binaire tableau de bord wordpress themes access to the same context as the template which includes them. This means that any variable defined in the main template will be available in the included template too:. The filename of the template depends on the template loader. You can access templates in subdirectories with a slash:.

The most powerful part of Twig is template inheritance. Template inheritance allows you to build a base "skeleton" template that contains all the common elements of your site and defines blocks that child templates can override. Sounds langue binaire tableau de bord wordpress themes but it is very basic. It's easier to understand it by starting with an example. Let's define a base template, base. In this example, the block tags define four blocks that child templates can fill in.

All the block tag does is to tell the template engine that a child template may override those portions of the template. The extends tag is the key here. It tells the template engine that this template "extends" another template. When the template system evaluates this template, first it langue binaire tableau de bord wordpress themes the parent.

The extends tag should be the first tag in the template. Note that since the child template doesn't define the footer block, the value from the parent template is used instead. It's possible to render the contents of the parent block by using the parent function. This gives back the results of the parent block:. The documentation page for the extends tag describes more advanced features like block nesting, scope, dynamic inheritance, and conditional inheritance.

Twig also supports multiple inheritance with the so called horizontal reuse with the help of the use tag. This is an advanced feature hardly ever needed in regular templates. There are two approaches: The automatic escaping strategy can be configured via the autoescape option and defaults to html. If manual escaping is enabled, it is your responsibility to escape variables if needed.

Any variable you don't trust. Escaping works by piping the variable through the escape or e filter:. By default, the escape filter uses the html strategy, but depending on the escaping context, you might want to explicitly use any other available strategies:.

Whether automatic escaping is enabled or not, you can mark a section of a template to be escaped or not by using the autoescape tag:. By default, auto-escaping uses the html escaping strategy.

If you output variables in other contexts, you need to explicitly escape them with the appropriate escaping strategy:. It is sometimes desirable or even necessary to have Twig ignore parts it would otherwise handle as variables or blocks. For bigger sections it makes sense to mark a block verbatim. Macros are langue binaire tableau de bord wordpress themes with functions in regular programming languages. They are useful langue binaire tableau de bord wordpress themes reuse often used HTML fragments to not repeat yourself.

A macro is defined via the macro tag. Here is a small example subsequently called forms. Macros can be defined in any template, and need to be "imported" via the import tag before being used:. Alternatively, you can import individual macro names from a template into the current namespace via the from tag and langue binaire tableau de bord wordpress themes alias them:.

If extra positional arguments are passed to a macro call, they end up in the special varargs variable as a list of values. Twig allows expressions everywhere. The operator precedence is as follows, with the lowest-precedence operators listed first: The simplest form of expressions are literals.

Literals are representations for PHP types such as strings, numbers, and arrays. The following literals exist:. Everything between two double or single quotes is a string. They are useful whenever you need a string in the template for example as arguments to function calls, filters or just to extend or include a template. If the string contains a backslash e. Integers and floating point numbers are created by just writing the number down.

If a dot is present the number is a float, otherwise an integer. Arrays are defined by a sequence of expressions separated by a commaand wrapped with squared brackets []. This is the value returned when a variable does not exist. Using double-quoted or single-quoted strings has no impact on performance but string interpolation is only supported in double-quoted strings.

The investor only needs to predict whether the price of the asset is going to rise or fall within a given time. The investor then selects Call if the prediction is a rise in price and Put if it is a fall.

The call option; meaning that the price of the asset will rise and reach 1. 3800 at least once in the next week. The put option; meaning that the price of the asset will fall and reach 1.
