|
||||
Syntax explanation
|
||||
------------------------
|
||||
|
||||
## variable
|
||||
`{{ variable }}`
|
||||
|
||||
Use dot (.) to access attributes of a variable
|
||||
|
||||
#### variable lookup order
|
||||
1. key of an associative array
|
||||
2. array-index
|
||||
3. object attribute
|
||||
4. object method call
|
||||
|
||||
**Example**
|
||||
|
||||
*in your template*
|
||||
|
||||
{{ person.name }}
|
||||
|
||||
*in php*
|
||||
|
||||
<?php
|
||||
$h2o = new H2o('template.tpl');
|
||||
$person =array(
|
||||
'name' => 'Peter Jackson', 'age' => 25
|
||||
);
|
||||
$h2o->render(compact('person'));
|
||||
?>
|
||||
|
||||
Let's say that you have assigned the value `Peter Jackson` to a 'person' variable in your php script. The following
|
||||
variable tag will print out `Peter Jackson`.
|
||||
|
||||
## Filters
|
||||
|
||||
Filters are variable modifiers that manipulate or format the value of a variable.
|
||||
A filter usually looks like this `{{ person.name|capitalize }}`, a pipe ( | )
|
||||
character after a variable, plus a filter name, will cause H2O to apply the filter.
|
||||
|
||||
__Filter chaining__
|
||||
|
||||
|
||||
Let me borrow the image from liquid template
|
||||
|
||||
You can chain multiple filters together and use a pipe ( | ) character to separate
|
||||
them. `{{ document.body|escape|nl2br }}`
|
||||
|
||||
__Filter arguments__
|
||||
Filters can accept arguments. For example:
|
||||
`{{ document.description|truncate 20 }}`
|
||||
will display the first 20 characters of the document's description.
|
||||
|
||||
Moreover, there are cases where you might want to pass in multiple arguments.
|
||||
Use commas ( , ) to separate them:
|
||||
`{{ person.bio|truncate 20, "..." }}`
|
||||
|
||||
__Filter named arguments__
|
||||
h2o uses colons ( : ) for named arguments. These allow you to build 'optional argument' arrays.
|
||||
|
||||
`{{ '/images/logo.png' | image_tag width:450, height:250, alt:"company logo" }}`
|
||||
|
||||
The above code translated to php will be like the below snippet, which resembles what happens internally:
|
||||
|
||||
<?php
|
||||
echo image_tag("/image/logo.png", array(
|
||||
'width' => 450,
|
||||
'height' => 250,
|
||||
'alt'=>'company logo'
|
||||
));
|
||||
?>
|
||||
|
||||
Note: Difference with Django, Smarty
|
||||
H2o does not use the colon ( : ) character to separate arguments for readability reasons,
|
||||
H2o uses the comma ( , ) which is more logical.
|
||||
|
||||
|
||||
## Tag
|
||||
|
||||
`{% tag %}`
|
||||
|
||||
Tags are very powerful, as they control the logical flow and structure of a template,
|
||||
There are inline tags `{% inline_tag %}` or tags that requires a
|
||||
close tag. For example: `{% if condition %} ... {% endif %}`
|
||||
|
||||
|
||||
### The "if" tag
|
||||
|
||||
`if` tags evaluate either a variable or a simple expression. If the result of the `if`
|
||||
expression is *true*, then the contents of the `if` block will be allowed to render.
|
||||
|
||||
{% if person.is_adult %}
|
||||
You are old enough.
|
||||
{% else %}
|
||||
sorry, you are too young for that.
|
||||
{% endif %}
|
||||
|
||||
### The "for" tag
|
||||
|
||||
`for` tags allow iteratation over an array of items.
|
||||
|
||||
{% for task in tasks %}
|
||||
{{ task }}
|
||||
{% endfor %}
|
||||
|
||||
The above snippet will print out each "task" in the "tasks" array.
|
||||
|
||||
Template inheritance
|
||||
------------------------
|
||||
H2o supports template inheritance. Inheritance allows you to factor out a lot
|
||||
of common code that would otherwise be duplicated across most of your templates.
|
||||
|
||||
Template inheritance is implemented using the `block` and `extends` tags, with child templates
|
||||
*extending* their parent templates.
|
||||
**Word of Caution:**
|
||||
* H2o templates only support single inheritance (just like PHP!), and currently do not support deep inheritance chains.
|
||||
|
||||
|
||||
Quote from the Django docs:
|
||||
> ... a base skeleton template that contains all the common elements of your
|
||||
> site and defines blocks that child templates can override.
|
||||
|
||||
|
||||
*Example:*
|
||||
|
||||
_base.html_ - defines the base structure of our pages.
|
||||
|
||||
<html>
|
||||
<head><title>{%block title %}This is a page title {% endblock %}</title></head>
|
||||
<body>
|
||||
<div id="content">
|
||||
{% block content%}
|
||||
<h1> Page title </h1>
|
||||
<p> H2O template inheritance is a powerful tool </p>
|
||||
{% endblock %}
|
||||
</div>
|
||||
|
||||
<div id="sidebar">
|
||||
{% block sidebar %}{% endblock %}
|
||||
</div>
|
||||
</body>
|
||||
</html>
|
||||
|
||||
As you can see, the base template is a typical web page using a two column layout.
|
||||
We defined two blocks (`content` and `sidebar`) and HTML code common across all of our pages.
|
||||
|
||||
|
||||
_page.html_ - defines a page-specific template.
|
||||
|
||||
{% extends 'base.html' %}
|
||||
|
||||
{% block content %}
|
||||
<h1> extended page </h1>
|
||||
<p> Body of extended page </p>
|
||||
{% endblock %}
|
||||
|
||||
{% block sidebar %}
|
||||
Sidebar contains use links.
|
||||
{% endblock %}
|
||||
|
||||
|
||||
The `page.html` extends `base.html`, allowing us to override any block
|
||||
previously defined in `base.html`.
|
||||
|
||||
Below is an excellent article about template inheritance in Django. If you wish to understand H2o's
|
||||
template-inheritance system, this would be a great spot to start, since H2o's template-inheritance system
|
||||
is strongly influenced by Django's.
|
||||
|
||||
[Power of inheritance][3] is a very good blog post explaining inheritance
|
||||
|
||||
[3]:http://www2.jeffcroft.com/blog/2006/feb/25/django-templates-the-power-of-inheritance/
|
||||
|
||||
*Tips*
|
||||
|
||||
* If you have found that you have several common elements inside the same template, it may be a
|
||||
good idea to put that portion of the template inside a `block` in a base template.
|
||||
* `block` give you a hook, which is useful, since these can help with javascript and css too.
|
||||
* When defining a block use a short and distinctive name
|
||||
|
||||
|
||||
|
||||
### Configuration
|
||||
There are a range of options for configuring the template engine.
|
||||
|
||||
<?php
|
||||
$h2o = new H2o('template.tpl', array(
|
||||
[option_name] => [option_value]
|
||||
));
|
||||
?>
|
||||
|
||||
#### Loader
|
||||
The name of the loader or an instance of H2o_Loader
|
||||
|
||||
__Use file loader [default]__
|
||||
|
||||
` $template = new H2o('index.html', array('loader'=>'file'); `
|
||||
|
||||
|
||||
__Advanced setup__
|
||||
<?php
|
||||
$loader = new H2o_File_Loader($custom_searchpath);
|
||||
$template = new H2o('index.html', array('loader'=> $loader );
|
||||
?>
|
||||
|
||||
__Use dictionary loader__
|
||||
|
||||
If you want to load templates from resources other than files, then this will be your
|
||||
friend. H2o uses `dict_loader()` for testing.
|
||||
|
||||
<?php
|
||||
$loader = dict_loader(array(
|
||||
"index.html" => 'Hello {{ person }}'
|
||||
));
|
||||
$template = new H2o('index.html', array('loader' => $loader'));
|
||||
?>
|
||||
|
||||
#### Searchpath
|
||||
|
||||
default: this will be the base path of your template
|
||||
|
||||
H2o use this path to load additional templates and extensions.
|
||||
|
||||
You can either explicity set the search path,
|
||||
|
||||
`$template = new H2o('index.html', array('searchpath' => '/sites/common_templates'));`
|
||||
|
||||
or h2o will try to find the searchpath for you.
|
||||
|
||||
`$template = new H2o('/sites/common_templates/index.html');`
|
||||
|
||||
#### Cache
|
||||
You can define the type of caching engine h2o should use, if any.
|
||||
Set 'cache' to false to disable caching.
|
||||
You can read more about performance and caching in following sections
|
||||
|
||||
Use file cache [default]
|
||||
|
||||
`$template = new H2o('index.html', array('cache'=>'file'));`
|
||||
|
||||
Use apc cache:
|
||||
|
||||
`$template = new H2o('index.html', array('cache'=>'apc'));`
|
||||
|
||||
Use memcache cache
|
||||
|
||||
`$template = new H2o('index.html', array('cache'=>'memcache'));`
|
||||
|
||||
Disable caching
|
||||
|
||||
`$template = new H2o('index.html', array('cache'=>false));`
|
||||
|
||||
#### Cache_dir
|
||||
When the file cache is used, you can define where you want templates to be cached.
|
||||
|
||||
It will put a cached template in same location as the normal template
|
||||
|
||||
`$template = new H2o('index.html', array('cache_dir'=>'/tmp/cached_templates'));`
|
||||
|
||||
#### Cache_ttl
|
||||
"cache_ttl" specifies how long a cached template should be used (defaults: 1 hour) before it is recompiled. The template fragment cache
|
||||
that is bundled in the cache extension will use this as default ttl value.
|
||||
|
||||
`$template = new H2o('index.html', array('cache_ttl' => 3600));`
|
||||
|
||||
|
||||
Performance and Caching
|
||||
------------------------
|
||||
|
||||
Caching can increase performance since it skips step of inefficient template parsing.
|
||||
H2o caches the template objects (the internal data structure of a template) and the bundled
|
||||
caching backends include File, APC, and Memcache.
|
||||
|
||||
### File cache
|
||||
By default h2o uses the file cache to store template objects. Change h2o option `cache_dir` to where you
|
||||
want to store template cache (ie: /tmp).
|
||||
|
||||
<?php
|
||||
$template = new H2o('homepage.tpl', array(
|
||||
'cache' => 'file',
|
||||
'cache_dir' => '/tmp'
|
||||
));
|
||||
?>
|
||||
|
||||
### APC cache
|
||||
APC is an op-code and object cache extension for php whose performance is
|
||||
generally 10-30% better than just plain file caching.
|
||||
|
||||
<?php
|
||||
$template = new h2o('homepage.tpl', array('cache' => 'apc'));
|
||||
?>
|
||||
|
||||
### Memcache
|
||||
Currently not implemented
|
||||
|
||||
|
||||
Extending H2o
|
||||
------------------------
|
||||
|
||||
|
||||
Known issues
|
||||
------------------------
|
||||
Yes, h2o has them. However, if you are careful, these shouldn't hinder your template development.
|
||||
The deep inheritance issue is a bit problematic for some template architectures, but again, if you
|
||||
are careful, and perhaps a bit inventive, it won't hinder you terribly much.
|
||||
|
||||
* `{{ block.super }}` doesn't work with more than 1 level of inheritance yet, so if `{{ block.super }}`
|
||||
invokes another `{{ block.super }}` it won't work just yet.
|
||||
* 'if' conditions don't support multiple expressions or mathematical expressions yet, like:
|
||||
`{% if something > 3 or something < 2 %}` or `{% if something + else > 12 %}`
|
||||
These likely will not be implemented in the future unless some daring soul implements them and
|
||||
contributes the code back to the h2o-php project.

* Inclusion with additional context variables passing:

* Note: Double quotes matter. In this example 'foo' template variable of subtemplate.html

* would be initialized with 'bar' variable contents (from main template context),
|

* while 'spam' template variable of subtemplate.html would be set to simple string ('eggs').
