case sensitive

Hi,

I have a problem with filter, because he integrated the case sensitive and i would like to recuperate a specific word inside a specific row.

For example: when i type ‘pau’ 0 result found and when i type ‘Pau’, 2 results found.

//var_dump($atts);

$sc = $atts['shortcode'];
$filter = 'filter='."'plato=". $_REQUEST['plato']."'";

$shortCodeString = '['. $sc;
unset($atts['shortcode']);

foreach ($atts as $name => $value) {
    $shortCodeString .= " $name=\"$value\"";
}

$shortCodeString .= ' '. $filter .']';
//var_dump($_REQUEST['plato']);

echo $shortCodeString; // DEBUG
echo do_shortcode($shortCodeString);

sorry for my english.

thanks
