Guide for combining Volt module engine and phalcon framework, voltphalcon
---- In recent work, web pages use the VOLT template engine compiled by C language, which is faster than loading pages dynamically by js, and more conducive to Baidu data capturing. Now we will sort out the usage ideas based on the document.
(Volt is a super-fast and designer-friendly template language, written in C language PHP. It provides you with a set of comments on Assistant writing a simple method. The phalcon framework is highly integrated with other components, just as you can use it as an independent component in your application.

Register the Volt with the view component and set an extension name or use the default extension. phtml:
<?php//Registering Volt as template engine$di->set('view', function() { $view = new \Phalcon\Mvc\View(); $view->setViewsDir('../app/views/'); $view->registerEngines(array( ".volt" => 'Phalcon\Mvc\View\Engine\Volt' )); return $view;});
<?php$view->registerEngines(array( ".phtml" => 'Phalcon\Mvc\View\Engine\Volt'));2. Basic usage
The Volt code is composed of PHP and HTML. Volt has a special set of delimiters, {%... %} is used to execute loop statements and condition judgments ,{{...}} used for value assignment.
You can use Phalcon \ Mvc \ View: setVar to pass the variables in the Controller to the View.
<?phpclass PostsController extends \Phalcon\Mvc\Controller{ public function showAction() { $post = Post::findFirst(); $this->view->setVar("title", $post->title); $this->view->setVar("post", $post); $this->view->setVar("menu", Menu::find()); $this->view->setVar("show_navigation", true); }}
In the preceding example, three variables are passed to the view: title, menu, and post:
3. VariablesVariables can have attributes and can be accessed through the syntax, such as foo. bar. If they are arrays, you can access them using foo ['bar '].
{{ post.title }}{{ post['title'] }}4. Filter
Variables can be formatted or modified using filters. The pipeline operator "|" is used to receive filter variables.
{{ post.title|e }}{{ post.content|striptags }}{{ name|capitalize|trim }}5. Notes
Add a comment using the separator {#... #}
6. Logical Syntax 1. for Loop2. if judgment
7. AssignmentYou can use "set" to set or change the value of a variable.
{% set fruits = ['Apple', 'Banana', 'Orange'] %}{% set name = robot.name %}8. Mathematical computingYou can use the operator +-* %/
9. Comparison Operators=! = <>><===! =
10. logical operatorsOr and not
11. Other operators~ |... Is not
{% set robots = ['Voltron', 'Astro Boy', 'Terminator', 'C3PO'] %}{% for index in 0..robots|length %} {% if isset robots[index] %} {{ "Name: " ~ robots[index] }} {% endif %}{% endfor %}12. View IntegrationVolt template integratedPhalcon \ Mvc \ ViewYour template hierarchy is the same as the default hierarchy. You can use partials as follows:
{{ content() }}{{ partial("partials/footer.volt") }}13. template inheritanceYou can create a basic template that inherits from other targets to improve the reusability of template files. The basic template uses a block to define a block, which can be covered by the quilt template.
For example, the following is a basic template.
{# templates/base.volt #}<!DOCTYPE html>Other templates can inherit from this basic template and replace the block in the Basic Template:
{% extends "templates/base.volt" %}{% block title %}Index{% endblock %}{% block head %}<style type="text/css">.important { color: #336699; }</style>{% endblock %}{% block content %}Not all blocks need to be replaced in the subtemplate (meaning that you can replace the desired part ). The final output result of the above example is as follows:
<!DOCTYPE html>As a piece, the path followed by "extends" is a relative path relative to the view storage directory (that is, app/views ).
/* By default, for performance considerations, Volt only checks whether the Sub-template has been modified. Because we recommend that you use 'compilealway' => true at the beginning of the development phase. In this case, the template always checks whether the parent template has been modified. */
14. ConfigurationVolt can change the default behavior through configuration.
<?php//Register Volt as a service$di->set('voltService', function($view, $di) { $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di); $volt->setOptions(array( "compiledPath" => "../app/compiled-templates/", "compiledExtension" => ".compiled" )); return $volt;});//Register Volt as template engine$di->set('view', function() { $view = new \Phalcon\Mvc\View(); $view->setViewsDir('../app/views/'); $view->registerEngines(array( ".volt" => 'voltService' )); return $view;});If you do not reuse Volt, you can register the Volt template engine as an anonymous function when registering the view service instead of using it as a service.
<?php//Register Volt as template engine with an anonymous function$di->set('view', function() { $view = new \Phalcon\Mvc\View(); $view->setViewsDir('../app/views/'); $view->registerEngines(array( ".volt" => function($view, $di) { $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di); //set some options here return $volt; } )); return $view;});
