Drupal：从自定义.module创建变量到自定义.tpl.php

Question

I create a custom module and I want use the complete_url of my future website in the template who used/created by my module.

I tried several ways and searched Google but I don't find a solution. However this issue seems very simply, that became me crazy x)

So, I must create a variable in my .module and add her when I return the array in the main_socialtag_theme function. Where/How can I do that ?

My .module:

function main_socialtag_block_info(){
    $block['main_socialtag']=array(
        'info' => t('Main socialtag'),
        'cache' => DRUPAL_NO_CACHE,
    );
    return $block;
}

function main_socialtag_theme(){    
    return array(
        'main_socialtag_block' => array(
            'template' => 'theme/main_socialtag_block',
            'variables' => array(),
        ),
    );
}

function main_socialtag_block_view($delta=''){
    if ($delta == 'main_socialtag'){    
        return array(
            'subject' => '',
            'content' => array(
                '#theme' => 'main_socialtag_block',
            )   
        );
    }
}

Thanks for help, and sorry for my bad english writing !

If you are looking for a way to add, modify and call variables. Check variable_get and variable_set.

To add or modify a variable value:

variable_set("my_variable_name", "value");

To retrieve the value:

$myVal = variable_get("my_variable_name", "");
