JSVars

A PyroCMS Plugin to get your PHP variables to JavaScript cleanly.

Installation

Drop the jsvars.php file into one of your plugins folders (e.g. addons/.../plugins).

Usage

Anywhere on your page, preferably inside of the <head> tag, place {{ jsvars:dump }}.

You can then fill the tag up with attributes, for example:

{{ jsvars:dump my_cool_variable="My cool value!" }}

This will generate:

<script>
    var myCoolVariable = "My cool value!";
</script>

Namespaceing

As we all know, global namespace pollution is punishable by death, so you can namespace your vars with the namespace="whatever" attribute:

{{ jsvars:dump namespace="whatever" my_cool_variable="My cool value!" }}

This will generate:

<script>
    var whatever = {
        myCoolVariable: "My cool value!"
    }
</script>

Default Values

By default, the plugin adds themePath and themeUrl to the generated variables, with the respective values, of course. I plan to add options to turn these off.

Events

This plugin triggers the jvars_dump event while compiling the key/value pairs, it expects a simple array consisting of key/value pairs.

I have not yet added validation/sanatization, because I'm lazy, but here's how you can pass you own values into the whole thing in a sample Events class:

class Events_Sample
{

    public function __construct()
    {
        Events::register('jvars_dump', array($this, 'onJvarsDump'));
    }

    public function onJvarsDump($data) 
    {
        return array(
            'this was added' => 'by some module'
        );
    }

}

Register your function call on the jvars_dump event
Return a simple two-dimensional array of primitive data types (no arrays/objects or something fancy)
That's it! If you now put

{{ jsvars:dump namespace="whatever" some_attribute_key="and its value" }}

somewhere in your theme, you'll get

Object {someAttributeKey: "and its value", thisWasAdded: "by some module", themePath: "...", themeUrl: "..."}

in your console by typing whatever.
