FnashJsParamBundle

Simple way to expose some symfony2 container parameters to javascript

Installation

Step 1: Download sources

Option 1: via Composer

Add FnashJsParamBundle in your composer.json:

{
    "require": {
        "fnash/fnash-js-param-bundle": "*"
    }
}

Then run:

$ php composer.phar update fnash/fnash-js-param-bundle

Option 2: via Git

$ git submodule add git://github.com/fnash/FnashJsParamBundle.git vendor/fnash/fnash-js-param-bundle/Fnash/JsParamBundle

or if you are using say SVN in your project

$ git clone git://github.com/fnash/FnashJsParamBundle.git vendor/fnash/fnash-js-param-bundle/Fnash/JsParamBundle

Add Fnash namespace to autoload

<?php
// app/autoload.php

$loader->registerNamespaces(array(
    // ...
    'Fnash' => __DIR__.'/../vendor/fnash/fnash-js-param-bundle',
    // ...
));

Step 2: Register bundle in AppKernel class

<?php
// app/AppKernel.php

$bundles = array(
    // ...
    new Fnash\JsParamBundle\FnashJsParamBundle(),
    // ...
);

Step 3: Import routing

# app/routing.yml

fnash_js_param_routing:
    resource: "@FnashJsParamBundle/Resources/config/routing.xml"

Step 4: Configure

Given your parameters file

# app/parameters.yml

parameters:
    param1:   value1
    param2:   value2
    param3:   value3
    param4:   value4

Add some parameters you want to expose in your javascript

# app/config.yml

fnash_js_param: 
    expose: [param1, param2]

Be careful! Do not expose critical infos such as passwords etc..

Step 5: Add javascript file to base template

    {% block javascripts %}
    .............
    <script src="{{ path('fnash_js_param_js') }}"></script>
    .............
    {% endblock %}
    </body>
</html>

Get your parameters from javascript

alert(FnashJsParam.param1); // value1
alert(FnashJsParam.param2); // value2
