This plugin allows you to output certain default variables and custom variables anywhere on your joomla website.
Output a code snippet like {{wi_var:my_variable_name}} anywhere in code/html and the system plugin will find and replace it with it's value.
It is even possible to access data of active menuitem using {{wi_var:menuitem:var_name}}. Works together with wi_menuitem_params!
A really basic if clause is possible too - but without nesting! Use {{wi_var:if:var_name}} stuff... {{wi_var:endif}}
Make sure NodeJS is installed, then download or clone the repository:
git clone https://github.com/jbjhjm/wi_vars.git
Change to development directory and run npm install.
use grunt build to create a package for joomla installer at ../build.
Use joomla installer to install. Change to plugin manager and enable wi_vars plugin.
After installation, following variables are immediately available to use with {{wi_var:name_of_var}}:
| Name | Description |
|---|---|
| sitename | Name of your Website as specified in Joomla configuration |
| baseURI | URL of your Joomla installation |
| year | Current yeat |
| date | Current date in d.m.Y format |
| time | Current time in h:i format |
| datetime | Current date and time in d.m.Y - h:i format |
| if:var_name | Hides content until endif, if var_name evaluates to false (false, 0, empty string, empty array) |
| endif | Ends content area controlled by if statement. |
| menuitem:alias | Alias of current menuitem (defaults to home item if no menuitem is active) |
| menuitem:title | Name of current menuitem (defaults to home item if no menuitem is active) |
| menuitem:some_var_name | Get any menu item parameter of current menuitem. Works with wi_menuitem_params plugin, too! (defaults to home item if no menuitem is active) |
locate /plugins/system/wi_vars/custom within your joomla installation. In there, you'll find two files named vars_.php/.xml. Remove the underscore to allow the plugin to access their contents. After renaming them you can also safely update the plugin without loosing your custom data.
Using the xml file, you can create parameters which can be edited in the wi_vars plugin settings. The xml file already contains a few example fields. Refer to [https://docs.joomla.org/Standard_form_field_types](Joomla form field types) to see what's possible.
Using the php file, you can declare your own variables or even execute PHP code.
Adding key/value pairs to the static $vars array is the easiest possibility.
Modify static function getVars to return any key/value array you'd like.
Define static function(s) with a naming scheme of processVar_[my_functions_name] and use {{wi_var:my_functions_name}} to execute them.
You can even use {{wi_var:my_functions_name:A_STRING}} and receive A_STRING as function argument.
