Can't get options with $data['variable']

Question

Can't get options with $data['variable'].

(I'm use SMOF - Slightly Modded Options Framework)

For example in the header.php (index.php, footer.php, etc.):

global $data;
$logo_type = stripslashes( $data['type_logo'] );

and nothing happens, variable $logo_type contains nothing.

But if I use the same code in the \css\styles.php - all works fine. Code from \css\styles.php:

<?php 

/* Background Body */ 
$bg_color = stripslashes ( $data['ct_bg_color'] );

?>

/* Body BG Color */ 
body, .body-class { background-color: <?php echo $bg_color; ?> 
}

Function as part of framework :

/*-----------------------------------------------------------------------------------*/
/* Generate a static css file from the defined options
/*-----------------------------------------------------------------------------------*/
// This function will generate a static css file which you can use in your theme.
// Some examples of the dynamically generated options has been defined in css/styles.php
function generate_options_css($newdata) {

    $data = $newdata;   
    $css_dir = get_stylesheet_directory() . '/css/'; // Shorten code, save 1 call
    ob_start(); // Capture all output (output buffering)

    require($css_dir . 'styles.php'); // Generate CSS

    $css = ob_get_clean(); // Get generated CSS (output buffering)
    file_put_contents($css_dir . 'options.css', $css, LOCK_EX); // Save it

}

First encountered this problem... And can not understand what could be the problem (php, web hosting, etc.)

Anyone else encountered this problem?

This is actually a PHP question, and not a WordPress question.

The issue is that global variables don't pass through the include()/require() call from the template file into header.php.

The solution is to define $data after you globalize it.

Without knowing your options framework or your Theme specifically, I can only answer in general terms; that said, you would likely define $data like so:

global $data;
$data = get_option( 'some_option' );

or

global $data;
$data = framework_get_options();

Hint: take a look at /css/styles.php to see how your framework/Theme does this, specifically.
