WordPress Theme Options Import/Export

maybe you can write 2 functions for your options

1. one script to write a txt file to export your options
2. one script to import in your wordpress (add upload field in your option
   theme page)

all of theses functions can be in your functions.php of the theme

here is an example of function to write a ini (txt) file

function write_ini_file($assoc_arr, $path, $has_sections=FALSE) { 
    $content = ""; 
    if ($has_sections) { 
        foreach ($assoc_arr as $key=>$elem) { 
            $content .= "[".$key."]\n"; 
            foreach ($elem as $key2=>$elem2) { 
                if(is_array($elem2)) 
                { 
                    for($i=0;$i<count($elem2);$i++) 
                    { 
                        $content .= $key2."[] = \"".$elem2[$i]."\"\n"; 
                    } 
                } 
                else if($elem2=="") $content .= $key2." = \n"; 
                else $content .= $key2." = \"".$elem2."\"\n"; 
            } 
        } 
    } 
    else { 
        foreach ($assoc_arr as $key=>$elem) { 
            if(is_array($elem)) 
            { 
                for($i=0;$i<count($elem);$i++) 
                { 
                    $content .= $key2."[] = \"".$elem[$i]."\"\n"; 
                } 
            } 
            else if($elem=="") $content .= $key2." = \n"; 
            else $content .= $key2." = \"".$elem."\"\n"; 
        } 
    } 

    if (!$handle = fopen($path, 'w')) { 
        return false; 
    } 
    if (!fwrite($handle, $content)) { 
        return false; 
    } 
    fclose($handle); 
    return true; 
}

You can use write_ini_file to send the values to a file, parse_ini_file to read them back in 🙂
