将MySQL变量传递给Joomla模块，而不是使用默认字段进行Twitter搜索

Question

It seems I've hit a wall here and could use some help

Would like to pass a MySql variable to a Joomla Module

Im using Yootheme's Widget-kit to display tweets from a search term. Works great and all but you need to enter the twitter search term in the Module back end.

Instead I would like to use a variable ( already used on the page) and pass that variable to the Twitter module so it can display the tweets I want

Here are some lines of PHP with the variable I'd like to use

$document->setTitle(JText::sprintf('COVERAGE_DATA_PLACE', $this->country->country_name,     $this->city->city_name));

$text = JString::str_ireplace('%city_name%',$this->city->city_name,$text);

$this->setBreadcrumbs(array('country','city'));

Is there any way to take the "City" variable and send it to the 'word" field found in the twitter module?

Here is the Code for the twitter module

<?php

I believe you can do what you want with this: http://www.j-plant.com/joomla-extensions/free-extensions/26-module-plant.html

This plugin supports module parameters overriding. Use the next code for overriding parameters:

[moduleplant id="77" <param_name_1>="<param_value_1>" <param_name_N>="<param_value_N>"] replace and with the necessary parameter name and value. You can override as many parameters as you want. Available module parameters can be found in module XML manifest file. A manifest file is usually located in the next path:

 modules/<module_type>/<module_type>.xml
