find_in_set

[sabret00the]

can someone run through this with me please?

PHP Code:

if ($do == "step3" AND $_GET['sectionid'] AND $_GET['category'])
{
    globalize($_GET, array(
    'do' => STR,
    'agree' => STR,
    'sectionid' => INT,
    'category' => INT,
    'goto'
    ));

    $sectionid = intval(trim($sectionid));
    $category = intval(trim($category));
    // make style dropdown
    $getstyles = $DB_site->query("
        SELECT *
        FROM prs_styles
        WHERE FIND_IN_SET($category,catid)
        ORDER BY catid ASC
    ");
    echo("
        SELECT *
        FROM prs_styles
        WHERE FIND_IN_SET($category,catid)
        ORDER BY catid ASC
    ");

    $style_dropdown = "<option value=\"0\">Select A Style</option>\n";
    $style['description'] = "Please select the style you feel best suits the piece you're about to submit.";
    $thetext1 = "thetext1[0]=\"" . $style[description] . "\"\n";
    $thetextcount = 1;
    while ($style = $DB_site->fetch_array($getstyles))
    {
        echo $style[description] . "<hr />";
        $style_dropdown .= "\t\t\t\t\t\t\t\t<option value=\"$style[styleid]\">$style[stylename]</option>\n";
        $thetext1 .= "\t\t\t\t\t\tthetext1[" . $thetextcount++ . "]=\"" . $style[description] . "\"\n";
    }
    eval('$prs_main = "' . fetch_template('prs_submit_styles') . '";');
} 


catid is either a solo number or a string "35 454 9845 908432 930483409 23434" shouldn't find_in_set do this perfectly?
